Firefox 技術支援討論區

Hi, this is going to be a long one, so many things... Using Firefox the latest Ubuntu LTS, with the latest Firefox from Snap. I'm a very long term Firefox user, never had any real troubles unit recently. I have a vast number of cookies, saved passwords and so on. Reinstalling or deleting cookies or such isn't an option unless fixes are guaranteed to work - if I have to start over then I'll do it with Opera, that is where my grumpiness indicator is at.

The set up is two monitors (working as a single 'screen') attached to an Aspire PC (Aspire X seems to be the model?). I tend to have 'stuff' going on in the left hand monitor, YouTube on the right. The PC is on all day. I know there are log files, but I don't know which is for what or where they are. I use AdBlocker Ultimate.

So what's happening is: Firefox crashes quite often at any time - 'Firefox is not responding - force quit or wait' - always have to quit. There doesn't seem to be any repeatable way to cause this, it seems random.

When the mouse enters the YouTube window (the drawing area, not the actual window) it disappears until the pointer moves out of the window. Jiggling the window size sometimes brings it back, but...

When the mouse pointer actually appears the window is completely unresponsive - clicks don't work, nothing highlights and so on. After somewhere between 10 and 30 seconds things will work for 2 or 3 mouse actions (clicks, drags etc) then do it again. Unless I give it plenty of time, clicking on a video will play a pretty random one - Firefox seems to lose track of where the pointer is.

If I comment on a video the I get about 5 to 10 characters in then nothing happens for 10 to 20 seconds, then any queued characters are shown. Rinse and repeat until the comment is complete - it takes ages.

YouTube is the biggest problem, but there are some glitches in other Firefox windows, I'm supposing that the problems are audio/video related.

None of the above happens with Opera. It's getting to the stage where Firefox is unusable.

I've googled and searched this site but the there seems no solution.

Any help appreciated.

Firefox takes about 5 minutes to load every it launches, before working smoothly like it should. This problem occured first time yesterday morning, and I have no idea what could have caused it.

It happens :

• when I launch firefox normally (whatever the profile)
• when I launch it from the terminal (it provides no output at all)
• when I tell it to launch the Profile Manager (5 minutes to see the Profile Manager appear, then 5 more minutes to launch firefox using the selected profile)

It does not happen :

• when I click "New Window" inside an existing firefox process
• when I call `firefox --help` from the terminal

Here's what I've tried :

• First, I've seen pretty much every article from Mozilla Support, Reddit or SuperUser (writing this question is kind of my last resort)
• I've tried removing and then reinstalling Firefox from Flatpak, from the Fedora repos (using `sudo dnf install firefox`) and using the manual install via the archive (v125)
• I've tried downgrading firefox (when using the package manager install) from v125 to v124
• I've also tried the Firefox Developer Edition, same problem here
• I've tried using the "Refresh Firefox" feature and restarting in Troubleshoot Mode (both are also affected by the slow startup, which makes them particularly painful to execute)
• I've tried manually deleting the `~/.mozilla/` folder (= manually deleting my profiles)

When firefox launches, it does not freezes my OS and does not seem to use many system ressources : CPU usage is normal, RAM as well, and it does not seem to read many things from the disk as well (I've seen some threads where this was the issue).

And here is something interesting that I discovered :

• loading (including refreshing) `about:profiles` is also slow and this time freezes firefox (OS reports it as not responding, I can't switch tabs and I can't see my mouse). Other about pages seem to work fine (although I did not try them all)

Thanks !

PS : Even if I think it has nothing to do with the issue, I prefer to mention it here : I was messing with virtual machines yesterday when the issue occured for the first time. My disk got full at some point and I don't know but it might have messed with firefox. At this stage, I had not deleted any files that could relate somehow to Firefox, that's why I doubt it would have caused anything harmful to Firefox. (instead, I mounted an empty partition from my disk to get some space)

I am using Firefox 125 in Windows 11. And this just happens recently.

Sometimes, quite frequently, when I click the addressbar wanting to input or select a new address. The Firefox UI freezes (before the dropdown list of addresses is shown). The video/audio/other effects are still working, and from task manager, it does not cost more CPU/mem than usual. But it does not response to key press or mouse action. All I can do (that I know of) is killing the processes. The problem does not seem related to "current" webpage I am browsing. And I have not installed new addons for a few months.

Any idea what should I look into?

When I would mouse-over a thumbnail on the Youtube home page I use to get a video preview with sound and text controls displayed. Video preview and controls are now missing on homepage thumbnails. Is there a way to get preview and controls back ?

I cleared the cache and cookies...no effect. Problem does not exist with Edge browser.

Using Windows 10 / Firefox browser 125.0.3 (64-bit)

Thru Firefox, I use Tineye to find related photos - I use it all the time, it's been great - I always use a VPN and have never had problems until now (as of yesterday). Now it won't search, a verify you're human window comes up, and I have to keep clicking squares, which I do - but then it says to allow cookies and start over. Well I don't want to allow cookies (I assume it's one of the options I have thru Firefox to block cookies), and I can't find where to allow cookies even if I did (I went to Firefox preferences etc) and I don't want to disable my VPN. Maybe I should mention that I just added or started a Mozilla account, as I have had immense trouble with my aol emails, and am trying to move everything over to a gmail account. My sign in to Firefox was the aol email, and I had to (try, I thought I did it) add another account, which I think I did successfully. So it was right after that, that all this started. Help please! Thank you!

In my Firefox email when I click on an email it opens to the entire page, but then if I want to get back to see the "Inbox" with the accounts and various folders I have created it seems the only way to do it is to scroll back on the line at the top which sometimes is short but literally sometimes takes a very long time and I don't know how close I'm getting, or I have to go up and click on the little contents box in the upper left corner, click on something else, like calendar or tasks to get out of email and then click on the contents box again and click on email. There has to be an easier way???

Thanks for any help in advance.

Hi, first the last update tried a few times over some days to install. Never got confirmation that it has been installed successfully. When I go to "About Firefox" I'm getting the information that I'm using the latest version.

Now I have problems, mainly when using facebook (especially when I try to play games through facebook) that Firefox uses enormous amounts of CPU and Memory. This does not happen all the time but at least in 70% of tries. I attached 2 screenshots

If this happens I'm not able to close Firefox the normal way but have to kill the process in the task manager.

Any quick help would be appreciated. I would also like to know if I'm the only one experiencing this or if it's a common problem.

Today while using firefox all my open tabs and windows crashed. Due to the situation, I had to restart my computer because everything was stuck. When it restarted I couldn't restore the previous session so I used various methods to restore it but I still can't restore the windows and tabs that were open today. I would like you to restore my session from before the failure today.

Hi,

My Mozilla Firefox Web developer tool keeps autonomously toggling on/off in any Firefox window/tab..

Its as-if I'm repeatedly hitting Ctrl-Shft-I (which brings up the web developer tool in the bottom 1/4 of the browser).

I've checked all Setting, turned off all hardware acceleration as suggested for similar flickering problem (which wasn't on anyway).

I use Norton 360 Security Software but have Norton Safe Web disabled. The only active Extensions are Firefox Multi-Container and Firefox Sideview.

Its not doing it at the moment, but I'm not sure exactly what triggers it and expect it to happen again.

Last time it happened I was browsing Amazon. Hitting Ctrl-Shift-I only makes is turn off until start scrolling again, etc.

I don't think its virus related, because I use Norton 360, and Task manager "Performance Tab" show the computer is generally very mellow.

Please help, as I love Firefox, but this problem can drive one crazy.

Thanks Larry Zdanis

I'm having trouble using my bank's website. Sometimes I can't log on (error messages) or I can log on and can't use certain features. The bank is Regions. The site works with other browsers. Is there some setting on the latest Firefox that needs to be adjusted? The articles I've read don't help. Thanks.

Sometimes I find that Firefox just randomly closes on my laptop, usually when I step away for about 10-20 minutes. I can't find any info in the about:crashes page when it happens.

Dear,

I have been using Firefox Developer Edition for many years without any problem. I sync Firefox on my different PCs, so they are basically all the same in setup. Unfortunately, Firefox now crashes constantly on my main PC. I have therefore temporarily switched to the default FF variant.

Of course I have tried all the steps shown here on the forum but without any result that I can see. Both in safe mode with or without addons. No matter FF crashed.

The error ID: Crash ID: bp-20d91ca4-1f79-4211-a3d5-4fd7c0240507

I hope someone can help me on my way ,

Regards,

Reinder

The animated images of the articles are loaded once every 3. On Chrome Android I have no problem.

I solve it manually by resizing the page, so they load.

Where could the problem be? In the animation of their site? Do you have any advice on a fix?

once every week or two, private browsing shows up in history. it is not cleared when i close all private windows. the rest of the time it works as it's supposed to. any suggestions are welcome. thank you. running 125.0.3 on mac ventura 13.6.6

I'm considering switching to Firefox for my primary browser BUT once I log in to AOL to check my mail, the print is tiny and cut off top and bottom of each letter. This is not a new problem, but I'm using Firefox more now and still have to use another browser OR another device to read my email. I am attaching a screen capture of what it looks like.

After loading the pop-up blocker extension I cannot access many links inmy email. Suggestions?

Tried uninstalling, selected to not include previous settings and reinstalled. Still having a problem.

Possible conflict with my firewall? How do I uninstall pop-up blocker?

Thank you
