latest update seems to have broken firefox 155.0.1. It opens but then becomes unresponsive. Two different PC, both win 10. How can I revert to previous?

I can not get extra info from troubleshooting page cause FF won't open so as to be used.

After every update, Firefox starts to a blank screen and will not start loading the webpage url put in for over twenty minutes to a half hour. During this time other browsers on my Win 10 PC load immediately so it is not a network issue. It is Firefox. When I see that an update is pending I hesitate to do the update because I know I will lose the use of Firefox until it is ready to respond. It just hangs with "loading X.com" showing at the bottom left of the blank screen. I have been using Firefox for a long time and in the past year or longer it has become very unreliable. There are also instances where without an update it will do this and the only way I can get it to work is to clear the cache and the history through settings. What is going on with Firefox! (And lately there is an update every couple fo days!

fonts.googleapis.com is locking up websites for 40 to 60 seconds per keystroke. I have researched this problem and tried everything suggested, but nothing works. Much of the solutions include changing the settings used on menus which no longer exist. accounts.google.com is doing the same thing. This is driving me nuts. Help!!! Latest version of Firefox. Windows 11 desktop computer.

i tried firefox, zen and librewolf but every of them has the same problem. smooth scrolling is sometimes good but sometimes so slow and laggy, especially in a tab that has a video. in tabs that has a video always have that issue and tabs that not has a video does it sometimes. its like scrolling is in 60hz when it happens. i tried uninstalling lots of times but didnt fix.

While running Firefox on MacBookAir with macOS 15.7.2 to browse simple websites I keep getting the below warning message. I may have 2 or 3 other apps open (like Apple Mail, MS-Word, Preview). "Heavy memory usage You're running out of memory and your Mac may become noticeably slower. Consider quitting some applications. Firefox 2,48 GB" So I quit Firefox to re-open again and continue my work. Does somebody has an hint where this message can come from ? Any settings to change on my MAC ? Thanks for helping

Firefox has been my entire family's browser of choice for as long as I can remember. Which one am I supposed to use now that Firefox won't quit shoving bloatware and diminished performance at me? I'm also seeing articles stating that they plan on making it even worse with more AI. I'm supposed to let them steal my data and turn my browser into sludge with absolutely no benefit to myself? And they're asking me to donate to them on top of it???

Does anyone know of a viable Firefox alternative that isn't a chrome dupe?

Whenever I have to restart my cpu, the menu bar appears to try to open all of the tabs and it causes system hangups and says that Mozilla Firefox is not responding. What causes this ??

I started noticing my browser was running rough, and I tracked it down to Youtube, but only when I have a video in fullscreen. It doesn't appear to be affected by the codec, av0/avc/vp09 all suffer from it.

Incognito mode (no extensions) is still affected by it, but a separate profile + troubleshoot mode are not. My RTX 5080 is showing about 2% usage when playing a video, 0% at idle.

How do I nail down what's causing this?

This is happening more frequently. sometimes clicking links works but the cursor will not respond if i hover over the new tab button. To continue I have to select a new firefox window, The unresponsive window remains in error even when a new working window is active.

Hello,

In the DevToolbox, the “Copy all as HAR” and “Create file...” functions are not working. It seems that in both cases, only empty space is placed in the clipboard and in the file (this has been happening since the last update).

Thank you in advance.

why does Firefox cover the whole screen when it hangs? it covers the bottom row of icons which I use to switch to a different task while I'm waiting for Firefox to finish hanging.

I on MacOS and I'm facing this issue last half of the year. As usual mac book user, I have many WIP items on my laptop, so I don't reload my laptop every day, even months it can leave without reloading.

So, after a workday I just closing it and come back tomorrow. When I back to the work and want to open new tab: Jira, Gmail, LinkedIn any other tabs - FireFox just keeping in loading state. In comparison, the Google Chrome that opened as well all the time but with fewer tabs, open the same links in seconds.

I though the FireFox is not latest version, and updating or re-starting of it, sometimes helped me to fix the issue. But now it seems stopped work either.

So, after a 5 years on FireFox I'm seriously started about my migration back to Google Chrome. I'm not sure that you can help me in this forum, but at least I would like to hear you option. Maybe anyone else have seen such behavior also and FireFox could find the issue

suse linux 15.6 firefox 140.9.0esr (64-bit)

An aggressive website can cause "isolated web co" processes to be started. When they hog all processors and memory, the computer besomes unresponsive. Keyboard and mouse freezes up.

Is there a way to limit firefox processes to n-1 processors, leaving 1 processor available for me to kill it ?

Hi I always use Firefox on my Apple I-Mac and it has always been excellent but in the last couple of weeks a window pops up to say that Dashlane is slowing down Firefox when I am trying to type in E-Bay. Not yet seen it in any other situation but it it virtually preventing me listing items for sale on E-Bay. Always have Dashlane open on Firefox whenever I am using Firefox/the internet. Today I reinstalled Firefox but it is still doing it. Help please! Kind regards Jeff Worth
