Firefox sometimes uses more memory (RAM) than it should. This can make Firefox slower and in extreme cases can even cause Firefox to crash. This post describes how to make Firefox use less disk space.
Firefox works better than most browsers with third-party plugins, but as the developers have already mentioned, some of them can slow down your computer considerably. In this way, they are working on a "Get the most out of Firefox" button that will stop all extensions when the browser is restarted (below). This alone could improve things and "you can always restart later," the developers say.
Update Mozilla Firefox
The first thing we suggest is to check for Mozilla Firefox updates and update them if there are any. Are older versions likely to have bugs or performance issues? Newer versions generally offer improved performance and fix bugs. To check for Firefox updates, open it and click on the three bands at the top right (Open menu), then on the “Help” option.
Mozilla Firefox starts to check for updates. If updates are found, Mozilla will install them for you. If you already have the latest version, you will see the status “Firefox is up to date”.
Disable extensions and themes that consume a lot of memory
Extensions and skins can cause Firefox to consume more memory than would normally be the case.
To determine if an extension or theme is causing Firefox to consume too much memory, start Firefox in safe mode and monitor its memory usage. In safe mode, extensions and themes are disabled. So if you notice a significant improvement, you can try disabling or uninstalling the extensions.
Restart the Firefox browser
As long as you notice that Firefox is using too much memory, it is better to restart your web browser. This usually helps you.
Before doing the same, set Firefox to store open tabs. It allows you to restart them where you left off.
Then open Firefox again and restore the previous session using the "Menu" button alternatives.
Reduce memory usage through Firefox settings.
You can customize some Firefox settings to work faster and use less disk space.
About: configuration settings
First of all, you should install the latest version, because in the latest version, the memory consumption has been greatly improved. They enable the browser to use the least amount of memory feasible. If your version is old, please update it. Or you can download the latest version here.
If you are using the browser, try opening the minimal tabs. Because if you have too many tabs open, they will take up more disk space and slow down the overall speed of your browser.
Type “about:config” in your browser and configure the following options in the list that appears.
- Browser.Cache.Ability .-> .setting.to.0
- Browser.tabs.animate -> disable
- javascript.options.jit.chrome -> set to true
- javascript.options.jit.content -> set to true
- Network.http.pipelining -> set to true
- Network.http.proxy Pipelining -> set to true
- Plugin.expose_full_path_full -> set to true
Decrease session history
browser.sessionhistory.max_entries determines the maximum number of pages in the browser's session history, in other words, the maximum number of URLs that can only be navigated with the Back / Step Forward button. The default value is 50, we generally won't browse more than 5 of the sites we've visited before, and there's really no need to store more than that in the session which can lock up memory as they grow.
1. open firefox
2. enter about:config in the Firefox address bar.
3. Press CTRL-F and search for browser.sessionhistory.max_entries.
4. Double click on the value 50 (or the current value) and change it to something lower, for example 5.
5. restart Firefox.
Enabling hardware acceleration
Flash content requires RAM to be loaded. Regardless, hardware acceleration in the Firefox browser can lower your memory load if a dedicated graphics card is installed on your system. So, in this step, we will make sure that the Hardware Acceleration feature is enabled.
