Mozilla Firefox is rightfully considered the most functional browser, because... has a large number of built-in tools for fine tuning. Today we will look at how you can fine-tune Firefox for comfortable use of the browser.

By default, the browser can store up to 10 closed tabs, which significantly affects the amount of RAM consumed.

Find the following option:

browser.sessionstore.max_tabs_undo

Change its value from 10, say, to 5 - this will still allow you to restore closed tabs, but at the same time significantly less RAM will be consumed.

Step 2: Improve Mozilla Firefox performance

1. Right-click on the area free of parameters and go to “New” - “Boolean”. Give the parameter the following name:

browser.download.manager.scanWhenDone

If you set the parameter to “False”, you will disable antivirus scanning of downloaded files in the browser. This step will increase the performance of the browser, but, as you understand, will reduce the level of security.

2. By default, the browser uses geolocation, which allows you to determine your location. This feature can be disabled so that the browser consumes less system resources, which means you will notice an increase in performance.

To do this, find the following parameter:

geo.enabled

Change the value of this parameter from "True" on "False" . To do this, just double-click on the parameter.

3. By typing an address (or search query) into the address bar, Mozilla Firefox displays the search results as you type. Find the following option:

accessibility.typeaheadfind

By changing the value in this parameter from "True" on "False" , the browser will not waste its resources on what is perhaps not the most necessary function.

4. The browser automatically downloads its own icon for each bookmark. You can improve performance by changing the following two parameters from True to False:

browser.chrome.site_icons

browser.chrome.favicons

5. By default, Firefox preloads the links that the site thinks you'll next open.

In fact, this function is useless, but by disabling it, you will increase the performance of the browser. To do this, set the value "False" to the following parameter:

network.prefetch-next

Having done this fine tuning (Firefox Setup), you will notice an increase in browser performance, as well as a decrease in RAM consumption.

Overclocking Mozilla. Simple fine-tuning + 14 Mozilla Firefox tricks and hotkeys

If someone’s browser suddenly starts to slow down, especially Firefox, then do the following simple operations:

1. Type about:config (copy directly from here) in the address bar: you will be taken to the settings menu by pressing the enter key.

2. Find the network.http.pipelining parameter, double click on this option to change the parameter from False to True.

3. Find the network.http.proxy.pipelining parameter, double click on this option to change the parameter from False to True.

4. Find the network.http.pipelining.maxrequests parameter, double click on it and change the number to 150 ~ 200

5. Right-click and follow New > Integer, enter nglayout.initialpaint.delay in the name and enter the number 0.

6. The browser.sessionhistory.max_entries variable is responsible for the maximum number of pages stored in memory. The value is 50. No good. We put 5, we are happy.

Yesterday I personally changed my settings, I couldn’t be happier with the results, so I highly recommend it!

Significant amendment: I recommend entering it manually into the address bar; there should be no spaces between the colons; when I published a post, this space constantly appears on the left and, if you copy and paste it in this form, you will end up either in Yandex or somewhere else.

14 Mozilla Firefox Tricks

1.To quickly find any word on a web page, type "/word" -slash brings up the quick search feature and the word you're looking for will be highlighted, then press Ctrl+G to "find" that word again.

2. If you want to delete any list item from the address bar drop-down menu, select it by hovering your cursor and simply press Shift+Delete.

3. Periodically clear your download history to make the download manager work better, this can be configured in the English version of the browser here:
Tools | Options | Privacy, and in Russified version here: Tools | Settings | Downloads.

4. Type about:cache?device=disk in the address bar to view/save objects that are in Firefox's disk cache.

5. Type about:cache?device=memory in the address bar to view/save items in the Firefox cache.

7.If you accidentally deleted a bookmark and want to restore it, open the Bookmarks Manager and press Ctrl+Z or in the menu:
Edit | Undo (Edit | Cancel).

8. Double-clicking on an empty space in the Tab Bar opens a new tab.

9.Hold the Ctrl key while right-clicking the View Image or View Background Image context menu to open the image in a new tab or window.

10. You can also drag the bookmarks folder to another location, but you must hold down the SHIFT key.

11. To prevent a website from replacing/modifying your right-click context menu, go to Tools > Options > Web Options, and then click on the “front tab” line and deselect the “Remove or replace context menus” menu . In Firefox 2: Tools> Options> content> Advanced (Tools> Settings> Content> Advanced).

12. You can work with Firefox offline - just go to File > Work Offline. This means that you can even view previously opened pages while offline - a great feature, but not many people use it.

13. You can bookmark an open page by dragging the icon from the location bar to your bookmarks folder. You can also drag it to your desktop to create an icon for that page.

14. To stop playing animated gif images, press the “ESC” button. And in addition... Keyboard shortcuts for easy working in Firefox from the keyboard!

To work comfortably at the computer, you need to have the right monitor, based on the lighting in the room. If there is a low level of light in the room, then, accordingly, so that the monitor does not dazzle the eyes, it is also necessary to reduce the brightness on it.

Method 1: Control Panel.

Open "Control Panel" and go to section "Screen" .

At the bottom of the page there is a slider with which we set the required brightness. There is no need to save anything, just close the settings window.

Method 2. Hot keys.

In laptops, basic computer parameters are controlled using hot keys. These keys usually work in combination with a button Fn.

As a rule, we settled on the F5 and F6 keys. On some keyboards these functions are located on the arrow keys. For clarity, they are marked with small pictures.

To decrease brightness, hold down the Fn key and start pressing the F5 key until you achieve the best screen brightness.

What I don’t like about Chrome is the flickering of the white background when drawing a page. As far as I understand, this happens at the engine level, and cannot be changed at the user level, even if you change the colors in the OS. I think that at this point we need to throw a stone at the Chrome developers. Why do they determine the color of the canvas themselves, and not take it from the OS system settings? The same goes for Skype and a number of other “serious” applications.

Opera

Not so much with Opera. All we could find was the Contrast Changer extension. Or a simpler option in the form of bookmarklet.
As an alternative to Clearly, you can use the online service Instapaper and their bookmarklet.
Also, the Stylish extension has recently appeared.
Selecting a dark theme. For example, Opera Simple Dark.

To change the interface color:
File > Options > General > User Interface options > Color Scheme: Black. To change the color of the paper (background), you need to change the colors in the OS.
I can't help you with older versions of Office.

Another bonus of “white on black” for mobile devices is that this combination consumes less energy(because it emits less light). How much less? Don't know. I suspect that with prolonged reading it is quite noticeable. It would be interesting to see the statistics.

Vision hygiene

Contrast

As mentioned above, don't use too much contrast (max white on max black). Contrast ≠ readability. Light gray on dark gray is perceived more comfortably. Which gradation of gray is selected individually.

Contrast plays a role not only in the image on the display, but also with the world around you. That is, take into account the lighting in the room and try to avoid too much contrast between the lighting and the brightness of the display/colors. This is especially true for night owls. If you already work in the dark, switch to dark color schemes - your eyes will be much less tired. The contrast between a dark and light theme in a dark room can differ by 20 times or more!

Distance

Don't forget about the inverse square law. If you are used to leaning towards the monitor, then when reading, increase the font size ( Ctrl+) and lean at least 15cm more back. This will significantly reduce the amount of light emitted to the eyes. Of course, the monitor has too large an area to consider it a point light source and apply this law to it. But as a simple example shows, when the ambient light is not too bright, leaning back from a distance of 55cm to 75cm, the illumination from the monitor decreases by 1.5 times (and even more in the dark). The recommended distance from the monitor is 50-70cm.

Breaks

Regular breaks from working at the monitor are more beneficial for vision than all of the above combined. But how does one remember to take regular breaks?

I absolutely loved the Workrave app. Adjustable for different time intervals and pauses of different lengths (for example, 3 short ones every 15 minutes, 1 long one every hour). It can block the system for a certain time without the possibility of canceling, which is very motivating to get up from your desk :) It has many little conveniences in the settings. For example, a few seconds before blocking, a warning pops up, and if you are too busy and don’t have time to pause, then you just continue working - the application will notice the activity (keyboard, mouse) and cancel the blocking. It also independently determines when you take a break and resets your timer.

Exercises

I suspect that most readers are familiar with the symptoms of computer vision syndrome such as spasm of accommodation (pseudomyopia, false myopia) or dry eye. There is enough information on the Internet on how to prevent these disorders through various exercises and gymnastics for the eyes. The main thing is to do them regularly, at least several times a day. I would like to separately note 2 types.

Human vision is designed in such a way that the normal state of the eyes (when the eye muscles are relaxed) is accommodation into the distance. Because the monitor is normally located relatively close to the eyes, the ciliary muscle is constantly tense to keep the lens convex for close focusing. This leads to fatigue and spasms of the ciliary muscle (pseudomyopia), and over time to permanent visual impairment. Alternately looking far and near, compensates for this stress, for which you definitely need to break away from the monitor (which Workrave helps well) and periodically exercise at the window for a few minutes.

The second type is face palming.

face palming

Yes, yes, that's it. So every time you react to an epic fail, you have the opportunity to stretch your eyes. This method is also known as palming. There is still a lot of speculation and controversial personalities surrounding this word. Therefore, I will immediately make a reservation that I recommend this exercise Not as a method to improve vision, and as a method to relax the eyes. Darkness gives the photoreceptors the opportunity to “rest”, and the warmth of warm hands dilates the blood vessels of the eyes and stimulates blood circulation. It will also moisten the eyes, since for some reason a person blinks much less when working at a monitor. Well, considering that the brain spends most of its energy on processing visual information, this is also a way to relax the gyrus a little.
(house) and without lighting (at night). Daylight was excluded because the result strongly depends on many factors (for example, weather) and has a large scatter in measurements.
Distance. For the long distance I took the length of my arm to be 75 cm. For the short distance - a slope of ~20 cm forward closer to the monitor.
Display brightness. In conditions without lightening, I carried out measurements twice - with the maximum brightness of the display and, accordingly, with the minimum.
Measurement results. I compiled all the data into one table. For comparison, I used the ratio between illumination in different conditions. As can be seen from the table, with “average” lighting, leaning back, the illumination decreases by 1.5 times. And in the dark, if you use a dark scheme, then the illumination decreases by 25 times.
Disclaimer! The results of the experiment do not claim to be universal, since the experiment was done “on the knee”. But I dare to assume that similar results will be observed in many everyday situations.

Add tags

Since I became the owner of a monitor with an extended color gamut, I have seen only advantages. The AH-IPS matrix with GB-LED backlight provides indescribable colors. Even without calibration, the monitor was pleasing, but after that... it was only pleasing at first.
Weeks later, I suddenly discovered that the colors that were displayed correctly in Photoshop and even the built-in Windows viewer looked terrible after I posted them online. I was reassured by the fact that the colors on the laptop are almost the same as what I see in Photoshop. For example, the color red looked acid-scarlet when viewed with a VKontakte browser.
The search only turned up old notes about enabling color management settings in FireFox. I couldn’t find a complete description in Russian, so I decided to give it here. Perhaps it will be useful to someone.

In the latest versions of FireFox, color management is enabled by default only for images with built-in profiles. A number of sites remove all information about color profiles, as well as other tags in JPEGs. Accordingly, FireFox displays incorrect colors on monitors with a wide color gamut (more than 1 billion colors).
How to fix it?

In the address bar of the browser enter about:config and agree that we will be careful. In the search bar enter color_management and we are left with 4 lines:

- gfx.color_management.enablev4
Boolean parameter that allows or disables color management. Set the value true

- gfx.color_management.mode

- gfx.color_management.rendering_intent

Meaning	Description
-1	Uses a built-in value. By default, the use of built-in profiles is disabled.
0	Perceptual. Tells Firefox to display images while preserving tonal detail. Suitable for most occasions, especially photographs.
1	Media-dependent colorimetric. The color spectrum is scaled so that the white point of the original image appears as a white point on the display device. This option is especially useful in cases where the image was created in an environment with a smaller color gamut than the display environment (monitor).
2	Saturation. This setting allows you to maintain color vibrancy by maintaining hue accuracy. The parameter is applicable for displaying graphs, diagrams and other cases where bright, highlighted colors are important and color rendering of shades is not so important.
3	ICC-Absolute Colorimetric. This option is applicable in cases where it is necessary to accurately convey colors, since FireFox does not make changes to the color scheme.

· gfx.color_management.display_profile
By default, FireFox uses the profile installed in the system by default for color correction. If you want to specify a different color profile, you can specify the full path to it in this parameter. After this, FireFox will ignore the system color settings in Windows.

NB: After changing the settings, restart your browser!

I have highlighted in bold those parameters that are installed on my system. Be prepared for the fact that the usual saturation of all images will decrease and you will see the pictures as on a regular monitor.
