Firefox doesn't render some websites properly.
I have been noticing this issue with websites with intense graphics and stuff like this Samsung's one:
I even tried opening it in firefox's default profile.
This doesn't happen with epiphany or chrome.
Firefox or Firedragon?
Firefox
Edit:
Are you facing the same issue?
I am facing the same issue in my Linux Mint installation.
All fine on LibreWolf and FireDragon 
Open issue on Firefox.
Nag the guys to properly support Firefox. All other browsers use webkit and are the same. A lot of web-developers today only test their stuff with webkit.
@SGS I see the same problem here with firedragon. The structure of the page renders ok, but a lot of the graphics are just not displayed (no download issue). So I am pretty sure the developers of the page are at fault here and use some webkit specific hacks.
There is no garuda-inxi, so not much context to troubleshoot an issue like this. Not every Firefox session is the same.
paru -S firefox-video-acceleration
I would have wished that the problem pages were posted and not just the home page, possibly I would have looked at more if it was about the Ultra with 12GB/1 TB 
If that helps Austin, I'm at work so no Linux here, I have opened up Firefox in WinCOUGHdows and all renders fine.
It is truly graphics intensive but no slowdown or rendering issue on a 4yo machine (this is bad with Windows). The short animated videos also work fine.
I did get a BSOD while I was writing this, but that has nothing to do with Firefox or that website, as I had closed Firefox prior. loll
I am on my old laptop with Linux-mint, which also has the same issue as on Garuda.
So what happened is my father had to get some work done on our new laptop with Garuda, and he was complaining that some of his work-related websites won't function properly on firefox. I installed chrome for him, and it's working now.
I will share my inxi, and check out your suggestions when I have the laptop.
Thanks

firefox-video-acceleration, it didn’t change anythinghow do I check that?
I suppose everyone is facing this issue in firefox on Linux, but @FGD didn’t face it on windows 
.
Actually, I have been noticing this issue in firefox for some time now, whenever the websites have some heavy graphics.
Thanks in advance.
Correct! And I will add to that: I face the same rendering issue as you on Firedragon Linux.
As I already mentioned, this issue is also there in Linux Mint.
So we can conclude Firefox Linux and its derivatives have this issue.
It would be nice if someone could report this bug to Firefox, it would be a little difficult for me as my exams are coming up, and I am also not exactly familiar with this process.
There is an environment variable which can be enabled for better performance on Wayland sessions, see here: Firefox - ArchWiki
If you switch back and forth, an easy way to have this taken care of automatically is add to your .config/fish/config.fish:
if [ "$XDG_SESSION_TYPE" = "wayland" ]
export MOZ_ENABLE_WAYLAND=1
end
I also was unable to get this website working correctly, but I’m not so sure there is a bug to report to Firefox or anything like that. It looks like there is a problem with the website:
I tried to force the website to load the page even though it is broadcasting insecure elements, but couldn’t quite figure out how to do it despite some hacking around in about:config. I discovered if you toggle security.mixed_content.upgrade_display_content from false to true, it will change the “connection not secure” badge to “connection secure”, but it doesn’t appear to change the elements displayed on the page in any way.
After working through this page here: Websites look wrong or appear differently than they should | Firefox Help, I found a link at the bottom to report a website that is broken on a specific browser at https://webcompat.com/. Here is the issue I raised:
It only took about ten minutes to raise the issue. I’ll let you know if they reach out or respond to the ticket in any way.
Now if I try to find non-functioning heavy websites(apple, asus etc.), everything seems to work. I think this Samsung's website was an exception. As far as I remember, I experienced this issue on other websites as well some time back, but now most of those seem to be fixed.
What actually caused me to post this issue here was my father's work-related website not functioning in firefox, and I had to install chrome 
. Now I don't know which website it was, but it didn't have any heavy graphics; it just wasn't responding.
Thanks, @BluishHumility, for submitting the issue at webcompat.
Hi to all,
I have the same problem with:
Firefox
Firefox ESR
LibreWolf
Firedragon
When trying the next URL:
Here my garuda-inxi:
My scenario is:
Distro: Garuda KDE Dr460nized Gaming Edition
DE: KDE Plasma 5.27.0
WM: KWin (X11)
I alredy have the:
paru -Q | grep firefox-video-acceleration
firefox-video-acceleration 1.0.0-1
More ideas ?
Thanks for your support !
I can't tell if you are just trolling or not. Have you had a chance to read through the previous comments in the thread?
