Tips and tricks to improve Firefox performance
Firefox is a very good browser, despite its underrated status on the market . It’s one of the few that doesn’t run on Chromium technology, and because of this, it’s almost a symbol of resilience in an internet dominated by big tech companies and, above all, Google. So, if you’ve decided to use it, the tips I give below will be of great interest to you, especially for improving Firefox’s performance.
Enables hardware accelerated rendering
One of the most effective ways to improve Firefox’s graphics performance is to let the graphics card do the work. Hardware rendering lets the GPU handle the processing of graphics and visual elements , thus offloading the heavy lifting from the CPU.
This is especially useful if you frequently have multiple tabs open with media content. You should do this:
- Go to about:preferences#general .
- Scroll down to the Performance section .
- Uncheck the option that says Use recommended performance settings .
- Check Use hardware acceleration when available .
Minimize the use of extensions
Extensions are useful, but each one consumes memory and resources, especially if they run in the background. Having too many active can cause browsing to be very slow, even if you’re not actively using them. In the end, it’s like having many small apps running at the same time.
The ideal is to clean regularly and keep only what you really need.
- Check the installed extensions in about:addons .
- Discard the ones you don’t use daily.
- Avoid extensions that do the same thing.
Use strict tracker protection mode
Strict mode not only protects your privacy, but also blocks many adware scripts, trackers, and third-party elements that load with every page. This significantly speeds up the loading time of websites, especially those heavily populated with ads.
Just follow a couple of simple steps:
- Go to about:preferences#privacy in the address bar.
- Select Strict under Tracking Protection .
Caution! Some websites or components may stop working. If this happens, temporarily disable protections for that specific page.
Increase the number of content processes
Firefox uses multiple processes to manage different tabs and tasks. If your computer has at least 8 GB of RAM, you can allow the browser to use more simultaneous processes . This improves stability and prevents everything from freezing if a tab crashes, although it will increase the browser’s RAM usage.
You can do it like this:
- In the Firefox address bar, type about:config and press Enter.
- When you see the warning, click I accept the risk and continue .
- In the search bar on the about:config page, type browser.tabs.maxForProcess .
- The default value is usually 8, which is the maximum number of processes Firefox creates per web page. You can increase this value to a maximum of 30.
Clear the cache regularly
Over time, Firefox accumulates temporary files to speed up the loading of frequently visited sites. But if too many are stored or become corrupted, they can do just the opposite: slow down your browsing. Therefore, periodic cleaning prevents this problem.
You can do it like this:
- In the address bar, type about:preferences#privacy .
- In the Cookies and site data section , click Clear data .
- Check only Cached Web Content and press Clear.
Additionally, you can delete other things, such as cookies, although this impacts privacy more than performance.
Prepare a clean profile if nothing works
When Firefox starts crashing for no apparent reason, it could be due to erroneous configurations or improperly removed extensions. Creating a new profile is like starting from scratch, but without losing your browser installation.
You can do it this way:
- Type about:profiles in the address bar.
- Create a new profile and give it a memorable name.
- Start it from there and see if the performance improves.
- From this same page you will also be able to delete old profiles.
Remember that your personal data is safe on Mozilla servers, as long as you’ve created an account and enabled synchronization.
To improve Firefox performance you can also reset the browser.
Additionally, there’s a trick to improve Firefox’s performance . It involves completely resetting the browser. It’s as if you were deleting it and reinstalling it.
It’s as easy as doing this:
- In the address bar type about:support .
- Click Reset Firefox…
- Finally, click Delete in the pop-up message.
Please note that your personal information will remain stored in your user profile. If the performance slowdown is severe, it’s best to create a new profile and then reset Firefox.
Always use updated versions
Finally, here’s a common but very pertinent reminder: Each new version of Firefox brings performance improvements, security patches, and optimizations. Therefore, it’s crucial to always keep your browser up to date.
