Updated to esr 128.14 Now Reddit (Redgifs) Hosting site for gifs crashes Firefox and cripples my PC. I've tried restarting in safe mode, then refreshing Firefox. Nothing is working. Reddit support just has an issue with the Gifs not playing, but nothing as extreme as what iam experiencing. I believe it may be something is preferences or a codec or something that was changed in the recent update. Any advice/ help would be great. Edit: OS is windows 10 latest updates Amd- Ryzen 7/32gig 3.20 ghz PC. So can handle a little bit of heavy browsing.. FF 128.14 esr Ext- Ublock Origin

Even with Addons disabled still occurs. Really at a loss here.

I have just installed Firefox on a new iMac, running MacOS 15.2. Firefox will not load any of the websites I have tried, whereas Safari and Chrome do. I have cleared the History and also set "No proxy" but loading still fails.

I have noticed a weird scrolling bug in Firefox since either v138.0 or v138.0.1.

If you go to https://www.architecturaldesigns.com/ and select any floor plan, if you attempt to scroll down the page the page will not let you and snap back to the top.

I tried this in Firefox troubleshooting mode with all add-ons / themes disabled and encountered the same behavior. This is something that just started happening in the last version release or two.

This is present both on Windows as well as Mac versions of the Firefox browser.

Hello,

This new version of firefox. I am experiencing icons grey out whenever I opened a new tab. Is anyone experiencing this below?

Когда firefox зависает и windows предлагает его убить, firefox получает права системы и по этому становиться не убиваемым.Система не может его убить потому что у его права системы .В первые заметил этот баг когда сделал браузер firefox браузером по умолчанию.У меня сим роутер при запуске системы открывает браузер тут та браузер и зависает (не всегда ,но часто) в диспетчере задач в этот момент у его права системы.Писал в майрософт ,майкрософт посоветовал пользоваться нормальным браузером и сменить браузер по умолчанию .По совету майкрософт сменил браузер по умолчанию на chrome проблема пропала. Firefox 140.0.2 (64-разрядный) Windows 11 версия 24H2

Have been having an issue for the past month or two where if left in the background firefox will slowly start to eat up my available ram. I was using it like this perfectly fine for years previous to now.

I dont have this issue when I'm actively using it, only when I tab away from it and specifically its not on screen. Once I tab back to firefox the ram usage immediately dips back down to normal. I have tried many things to try and solve this like doing a clean install of firefox, getting rid of extensions, clearing my browser cache, closing all other apps to verify it was just firefox, clearing my history, turning on hardware acceleration. Nothing seems to help, im really at a loss and I don't understand what changed besides it being updated in the past couple of months.

My computer is fairly heavy duty and I have 16gb of ddr4 ram that again was working perfectly fine to run firefox before these past couple of months. As a result of this issue however if left in the background for too long on accident firefox uses up all my idle ram and starts causing other programs to not be able to run and has even crashed my computer previously when trying to run a program like clip studio paint.

I have noticed that while running the firefox task manager there is definitely some difference in memory usage when i tab back in after letting it be in the background so I have attached screenshots of the regular usage while tabbed in and the captured usage when i tab back in.

Any possible solution is welcome because I really enjoy using firefox and i dont want to have to switch browsers unless absolutely necessary.
