I know the Linux community has a hard time accepting this, but Firefox’s rendering engine is trash tier. Even in Windows.

I don’t know the inner workings or politics, I can only go by anecdotal evidence. Firefox runs like shit for me on everything.

🤷‍♂️

Going by my experience, the problem is something else at your end. Mind you, I don't load it down with loads of extensions.

May I ask: when did you last try Firefox? There was a period during the 2010s when it has truly horrible performance, but they rolled out some major updates several years ago that greatly improved performance (though wouldn’t call some of the UI changes improvements).

Honestly, every major rendering engine is terrible in some way.

  • Blink is resource intensive and has so many non-standard APIs for the sake of Google’s version of “Embrace, Extend, Extinguish”.
  • WebKit takes 50 years to support the newest standards.
  • Gecko (Firefox) is non-modular and is limited to being used in Firefox, Thunderbird, and forks and Firefox as a result. Its performance is also somewhat worse than Chrome’s, but not noticeable for daily use.

Ultimately, I choose Firefox because its issues are the least annoying to me. I do wish its structure was more community-based and less corporation-eating-its-own-hand, but whatever. So long as Debian sees it fit to keep in its repos, I’ll use it.

Moved off Firefox this month. I was die hard Firefox user for decades. All the way back to Netscape and the original Mozilla browser with the t-Rex logo.

I tried using zen and librewolf but they both suffered the same problem. Dogshit engine.

May I ask what your config was, such as distro, packaging format, and extensions were used? Also, what hardware?

Additionally, what issues specifically were you experiencing specifically? Were sites just loading slowly?

I ask because I’ve used recent versions Firefox on decently old hardware with 4 GB of RAM and 2 cores and had almost no problems. Everything rendered correctly and in a reasonable amount of time. I’d be curious to know why that isn’t happening for you.

It’s not that it renders incorrectly so much as abysmal performance. Choppy scrolling, page elements taking a long time to load, etc.

I did a bit of distro hopping lately so it was on a few distros mainly arch and Fedora base.

Also experienced this in windows 10 and 11.

the only sites ff is shit for is Google sites imo (e.g. earth and maps)

otherwise it's fine

Also YouTube

Changing the user agent seems to help in some cases

Honestly, even those don’t run that horrid for me when I have to use them.

[-] Jumuta@sh.itjust.works 3 points 2 weeks ago* (last edited 2 weeks ago)

they're not unusable but you can definitely notice there's some Google fuckery going on

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
