Best is to leave all those prefs at their default and quite a few that have a trashcan at the far right on about:config are no longer supported anyway and you can click that trashcan to remove them. Randomly changing prefs because you see them mentioned on internet without knowing what they are about is highly discouraged.


WARNING: modifying prefs directly via the about:config page can sometimes break Firefox or cause strange behavior, and there is no guarantee that this will keep working in future Firefox releases, so be cautious with modifying prefs if you aren't sure you understand their purpose. You should only do this if you know what you're doing.

Thanks for your response but no I really want to know which of them exactly are increasing the speed of Firefox.

You can't increase the speed of the Browser that is related to your ISP bandwidth.

Sorry, but that's not true because I already modified them all as I listed them in my question, and indeed the speed increased around 1.3-1.7 seconds. I did several speed tests btw.

I just don't know which one of them exactly increased the speed.

There is hardware acceleration but that is a hit or miss depending on the setups.

Yeah I'm using recommended performance settings because when I uncheck this Firefox slows down incredible imo.

Btw, I found these 6 websites from which I got these settings:

https://www.drivereasy.com/knowledge/speed-up-firefox/ https://www.greengeeks.com/tutorials/increase-firefox-page-loading-speed/ https://www.wikihow.tech/Make-Firefox-Load-Pages-Faster https://www.webnots.com/fix-slow-page-loading-issue-in-mozilla-firefox/ https://www.problogbooster.com/2010/03/make-mozilla-firefox-faster-speed-up-browsing-about-config-settings-easy-tricks-addon-performance-tweaks.html https://www.maketecheasier.com/28-coolest-firefox-aboutconfig-tricks/

I followed every single step of this guides.
