Firefox Community Forum

a few months ago firefox started rendering images funky. I am not sure what changed, it seems to be a setting problem as other computers with FF 135 don't seem to do this. I have not been able to come up with the right search terms to describe the problem. here is a screen shot of the issue.

First issue, as subject suggested, it always on. Meaning, if I type random letters or website shortcuts, it will go through ctrl f and not what i intended. it is very annoying.

Second issue, so far, if i close twitch, astro or youtube tab, the Firefox will automatically unresponsive and require to close and relaunch to kinda fix it.

This started about a year ago. Whenever I click on an MSN article, the screen jumps about half a screen away and I need to scroll to get back to the headline and click again. This does not happen on any other website. It does not happen when I use MS Edge browser.

I am on a Mac desktop running Ventura 13.7.3 and running Firefox 135 with extension of Ghostery, Privacy Badger, Google Don't Track Me, Facebook Container, FoxClocks and SoftGreenLeaves theme. All of these extensions have been playing nicely with each other for a long time.

Recently I've been having trouble recently with Firefox doing that thing of suddenly freezing/producing multiple windows and I need to refresh in order to get it working properly again. This has happened three times in the last five days - so frequently that I now keep the refresh instructions on my desktop. Today I heard the CPU grinding and clicked open my Activity Monitor to see four listings of 'FirefoxCP Isolated Web Content' running all of them using in excess of 2Gb. Unfortunately I wasn't able to get a screenshot of the Activity Monitor while this was going on as I had the Mac force quite Firefox and the moment I did, the activity stopped, but I've attached an example of the Activity Monitor showing still high CPU values for a few moments of browsing.

So what's up? How can I stop the CPU grab? How can I stop the frequent crashing?

For tab settings I have checked these: Open links in tabs instead of new windows When you open a link, image or media in a new tab, switch to it immediately

In the past links opened in new tab immediately. But now some links open in SAME tab immediately. For example: I open https://www.pbs.org/livestream/ and start watching the livestream. When I click the link On Air Schedule It opens immediately in the same tab, which ends my livestream

For several weeks now, I have been unable to upload videos to a group in Facebook using Firefox. Previously, I posted a video almost daily. The loading wheel keeps spinning. This in Windows 11 Pro version 24H2 with Firefox 135.0 (64 bits).

Доброе время суток!

это папка C:\Users\Илья\AppData\Roaming\Mozilla\Firefox\Profiles\v2zudvil.default-release\storage\to-be-removed постоянно растет, удалять ее приходится вручную, почему так происходит? и как это избежать 

последний раз, когда удалял, это папка занимала 52ГБ

My firefox is using up too much memory, up to 60% of my laptops memory, even when I am not using youtube. and I can't figure out what is causing it to use so much. I've used minimize memory to no effect, can you figure out what is causing it? This link has a memory report to help

Has anyone else noticed that the memory leak issues have gotten way worse since last update?

I work on a potato. Most of the memory is in the windows paging file, on a mechanical hard drive. So freeing up used memory takes longer than it would on a machine with a metric tonne of quad-channel RAM. The past 6 months, Firefox has started having memory leak issues, where it just uses more & more memory until the paging file hits its hard limit and windows kills firefox.

But since last update (135.0 x64), the memory leak issue has worsened significantly.

If I open firefox, and then tab between all current tabs, I get maybe 5 GB of memory usage. So even if all tabs are marked as "active" and loaded into memory, this still isn't enough to cause issues.

But after 30 minutes, that memory usage has ballooned up to >20 GB, at which point windows decides that it needs to free up memory, and kills the process. Which is annoying, because then the browser reverts to the last saved state, meaning many tabs can be lost or reset to several clicks back.

I've tried shaving off extensions, with zero change. I've tried increasing paging file size, but that's just kicking the bucket down the road.

Anyone have a solution to this?

Firefox has recently become unreadable--it is blurry, then clear, blurry, then clear. It has become unusable. I've moved on to Edge. After much research, it is apparent that this is a problem unique to Firefox, who hasn't bothered to address or correct this issue. No more Firefox for me:(

About once a minute or more Firefox lag by 10-15 seconds before showing a character or characters I have typed.

It seems to be using a lot RAM. I have one window open with six tabs, including this one, and it is using nearly 8GB. There are 48 processes showing in Activity monitor.

I am using version 135 on a Mac Book Pro running MacOS 15.3 (Sequoia).

It is almost unusable.

Suddenly without warning, my Firefox browser (I guess it's 135.0) is no longer able to access my Yahoo/AT&T email account. I can do so with my I.E. browser (I never it used until this week) with no problem. This is has become a hassle for me.

https://mail.yahoo.com/d/folders/1 is the URL that no longer functions with this new Firefox browser.

Disheartening! Are there any solutions?

javascript does not work even though javascript.enabled is true.

Every time Windows 11 shuts down and reboots, a google search produces the same error screen stating javascript is not enabled, go to about.config, set javascript.enabled to true -- which every time is set at true already.

This is a huge pain in the butt!!!!!!!!!!!

windows 10 firefox was attacked by a scammer which declared that any attempt to shut down would cause problems. so i reloaded with some difficulty and subsequently the highlight function is blocking my screen

For the last few days, I have noticed when I pause a YouTube video and move on to using other applications. Suddenly the video starts playing out of nowhere, this ghost action is irritating. Can someone please fix this issue?

version: 135.0 (64-bit)

Firefox User here since Netscape Navigator. Problem occurred with latest Firefox release as far as I can tell. This rig works flawlessly with everything but Firefox and Thunderbird Chrome and Edge have no problems. All my apps operate normally. Almost all aspects of the browser/ display window are corrupt. Chrome and Edge and all apps function without issue. Included are two screen shots In attempts to resolve this issue I have uninstalled the video driver several times, including the use of DDU. I have done a deep uninstall of Firefox, including cleaning the registry and all hidden files. I have tried the latest video driver and several earlier versions; all exhibit the same issue. I can't use Firefox and its driving me nuts. I'd like to understand why Thank you for any advice and hints in advance
