(android version)It's so slow that when it takes too long to open a page I just copy the link and use brave.the only reason I use firefox is ublock origin.And no I wont be clearing cache now and then it happens fairly quick after clearing anyways.And I tried to disable extensions even ublock and it still is slow.remind you no other browser has any performance issues.Its even worse when a website login to account needs verification that needs performance and it takes too long.I just give up and login through another website.Well this is me ranting I wont be changing browsers unless ublock gets taken down.nor waiting for an actual solution there seems te be none anyways.Well thats all

Firefox is being flagged on my Android tablet as having too high background battery usage and it wants to put FF in deep sleep. This has just started happening. Also in the last several months, FF keeps freezing on my Android Tablet and I constantly (daily) have to clear the cache in the app. What has changed? If this continues I will have to uninstall this product.

switching windows in and out Firefox android seem to reload the open page, this sometimes means significant waiting time and in case of scrolling pages the loss of your last position

Hi there,

I am on a MacBook Air M3/8GB ram. I was really wanting to use Firefox due to your stance on privacy, etc. but here is my experience:

Yes, I keep a lot of tabs open - I do try to group them and hope that tabs in closed groups are deactivated, but I don't know this at all.

If I use Firefox all will seem well until my machine sleeps. On waking, it is excruciatingly slow - we are talking multiple seconds to even switch tabs or get the cursor to be "hot" when filling a form. Upon trying to quit (restarting being the usual first step), FF will ask confirmation and then close the windows, but will not completely quit, requiring me to force-quit. On restart it seems to behave again, at least for a while.

While I do see some evidence that others have this issue (memory leak?) there are no real methods or answers as to how, if at all, to fix this. It took a lot to get everything on FF working the way I like after leaving Chrome, but I really can't deal with this, and I think I will be looking at switching again - I guess to Safari.

I would love to know how to fix this, but really I don't imagine this is due to my system as much as the FF browser. That said, if you ahve any ideas, I would be open.

Hello! So long story short I've been looking to switch my default browser to Firefox and I would've done so by now if it wasn't for this small issue.

It's not anything super important, but it has been mildly annoying to deal with. I can't say for certain how long this has been an issue in general since I've only just started trying out the Firefox search widget about a week or two ago. The issue happens every time I use the search widget and seems to happen infrequently when I use my private tab shortcut too, but doesn't happen when I use the app directly however. After a initial search (when you first open the widget/tab), my keyboard would freeze on screen (sometimes fully opaque and other times a bit transparent in a similar way to a screen burn). I can only fix it by either exiting and re-entering the app/tab or by clicking on a link and having it redirect me. I have zero clue as to what could be causing this or if it is some kind of bug?

Any help would be appreciated, thank you!

Is anyone looking into this? I found an article that told me to remove some cash files and it seemed to fix the issue but it continues to reoccur. Some apps such as MS360 Outlook seem to trigger it, but if it was truly just a corrupt cache issue then cleaning the cash/profile once should have fixed the issue. Instead its become a constant pain in the *** and I'm tempted to find another browser. Seems very recent as well as I've never had issues with firefox before.

Ubuntu 24 Mozilla Firefox 151.0.3

I'll be on a page, maybe Facebook, the NYTimes, Amazon, or really any site, and suddenly I find I can no longer scroll, or otherwise navigate the page. I usually have to refresh the page, not so great an option, if I was in the middle of doing something, and and then it'll work OK. I shouldn't have to be doing that, and wonder why pages will just freeze up like this.

When firefox is loaded and as high as 13 can load. If go to task master and search for firefox it shows 13. If I try to delete 1 file all are deleted. If I delete firefox and try to add it again it says I already have firefox loaded.

I am a user and not good at using all sort of commands etc

Добрый день. Сегодня обновился у меня браузер до последней версии и перестал нормально открывать странички сайтов открывает и через время зависает почините пожалуйста скрин смотрите вот так все зависает и не отвисает

i used firefox version 144 or 148 and it frequently become whitescreen "but when i put or move my cursor hover, it becomes reload the page again. but it's annoying error bugs

When accessing only specific web pages, the screen freezes during loading. Backing, refresh, etc., are not working at all. The only way is to close the tab. I'm curious about the solution.

MacOS, M2 2023, fully up to date firefox.

Sometimes I'm using firefox and it just stops loading pages, internet is fine. Other browsers work. I look at my activity monitor and nearly 100% of my 32GB of ram is being consumed by various firefox processes. A lot of those processes seem to be associated with youtube. This problem usually, but not always, is resolved by restarting firefox. But this shouldn't be happening. I have a lot of tabs open sometimes, but it's not that excessive. And most certainly not 32GB worth and preventing my computer from doing a google search.

If there's a debugging thing I can do to post system logs, let me know and I'll post them next time this happens. I'll be away from my computer until early July, so around that time.

Hardware acceleration is turned off. Firefox does not show the GPU usage in task manager (which is very worrisome in its own right) but when watching a single stream twitch.tv my GPU usage is 60%~100% (which only shows on the GPU tab of task manage). If I close firefox, the usage returns to 0%. The usage also becomes 0% when the stream is not the active tab.

I believe this is a recent behavior change as I noticed it due to it causing games to have low FPS. The excessive usage is also present with only firefox running.

This is happening on a 7800x3d, RX 7900 XT and 32GB of ram.

I also tested on youtube and found it to be using 10% less gpu on average but after while it settles down to ~30% usage.

If I enable hardware acceleration, Firefox uses the iGPU at ~50% usage and still uses 50%~60% of the dGPU. Performance of videos doesn't seem to change whether hardware acceleration is on or off (where as on chrome there is a very noticeable difference).

Used Chrome for sanity checks and it does not affect games FPS while using on average half the GPU usage of Firefox. Chrome also reports it usage in task manager correctly.

I suspect Firefox may be calling GPU encoder\decode hardware incorrectly and always using hardware encoders\decoders regardless of the hardware acceleration setting.
