Firefox 社群討論區

I suppose this is a kind of support question, of sorts, but in my opinion this also has to be treated as a complaint, in a sense.

About one and a half months ago, Firefox became unresponsive, that is, it became awfully slow. I experienced just about every issue with the browser that was mentioned in the following support pages and support issues (posted by others) and I read all of those :

Websites don't load - troubleshoot and fix error messages

https://support.mozilla.org/en-US/kb/websites-dont-load-troubleshoot-and-fix-errors#w_the-problem-only-happens-with-certain-websites

firefox is extremely slow or fails to load sites

Secure connection and security warning error pages in Firefox https://support.mozilla.org/en-US/kb/secure-connection-failed-firefox-did-not-connect

An oddball situation had occurred in which I couldn't for the likes of me go to my librarything.com homepage at each restart of the previous Firefox session, which also causes lagging when the session wants to connect to the other (normally unproblematic) website session tabs, and I also get multiple connection errors + insecure connection notifications for some of these websites. (sometimes refreshing a page does not help, sometimes it does)

I got bored reading all those support pages and trying out the solutions, because nothing seemed to help. In the long run, I decided to de-install the whole browser after backing up bookmarks, speeddial settings, passwords and the whole profile. Simultaneously, I also tested the connectivity to these websites in another browser (Brave) and this did not present me with any problem.

So I did the following :

1) deleted the whole cache and closed the browser 2) uninstalled FF with Revo Uninstaller (which has an option to remove all remnant files / folders/ registry items on the Hard Drive) 3) made sure to remove all cached leftovers from HD by using multiple cleanup tools in succession : 1) Wise Disk Cleaner followed by 2) Bleachbit followed by 3) CCleaner

Went to the mozilla website, downloaded and installed the last version of FF. Next, imported bookmarks, speeddial settings and passwords. Next, reinstalled the Firefox extensions I used before (without any lag until one and a half months ago). I also did NOT copy the stored profile but decided on starting afresh with a new profile.

Everything worked lightning fast and efficiently until a few days ago, when I received an automatic update of Firefox - 151.0.3 - and all of a sudden, the same problems are reoccurring. And again, I can't connect to an unproblematic website like librarything.com, whereas before the update I was able to without any problem !!!

What the hell is going on with these auto-updates ???

How do I fix spotify images being grey? when I'm not logged in I can see he images of albums but whenever I log in they turn grey and I can't see the album/song image. Is there any way to fix this? I added a image for some context if that helps :) it's how the greyed out songs look.

When I copy a post in X from Firefox into a text file, it loses formatting, but when I copy the same post in X from Edge into the text file, it keeps formatting. Why?

Hi,

I’m using the latest version of Firefox on Windows 11 (currently v126.0), and I’ve noticed a recurring issue: the browser freezes for a few seconds when I switch between tabs, especially if one of the tabs contains a media-heavy website (like YouTube or online editors).

The browser doesn’t crash, but becomes unresponsive for 5–10 seconds before catching up. Task Manager shows a CPU spike during the freeze. I’ve tried the following:

-Clearing cache -Disabling all extensions -Running in Troubleshoot Mode -Updating graphics drivers

None of these solved the issue.

Is this a known problem? Any suggestions on how to fix or further debug it?

Thanks in advance!

can not resolve repeated problem : "The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. Some security software can cause this problem." Cánt not find "Refresh"

Since the last update its a mess. My advisors are telling me its loading slow I cannot connect with them in their chat............Chrome is fine

Can someone figure this out?

Thanks

Mozilla Firefox 115.25.0 (x64 en-US) won’t close since my previous version was updated on 6/29/25. I have tried closing it in my Win7pro Task Manager on several occasions, and had even tried to uninstall and then reinstall it from my “Programs and Features” menu, but I keep getting a message that the program can’t be uninstalled until it is first closed. Nothing I do fixes this problem. HELP

This video down helper is unstable it works when it wants to and stops working all the time can't somebody do something about it I paid for the license what more do you want fix this thing

I know, sounds stupid, but it is what it is. It happens rarely, only with Firefox on the secondary display from my laptop, via HDMI. It starts with some random few thin horizontal bars across the window itself, and soon, it turns off my display. It seems the bigger the window is, the more severe the issues. So full screen usually, it shuts it off and keeps it off. Not black screen, no signal style. I manage to get it out by Winkey+arrow. If i then put it back same issue. If i lower the width of it, it manages to stay coherent longer, but still resets the display with a quick black screen on page reload. The lower bounds on a 1920x1080 display resolution was 1515 pixels. At 1515 pixels, it works fine, once this is triggered, it's very repeatable on 60-70% of webpages. If i drag another window on top of Firefox, the monitor comes back up.

Before anyone asks: I have tried turning off hardware acceleration. I have tried putting firefox.exe to run on the integrated video card and on the dedicated 1060 Max Q videocard. I have cleared cache and etc.

This persists on a Windows session, across multiple Firefox restarts. A computer restart technically fixes it but i have no clue what triggers it. Laptop monitor works fine.

If I need to upload a file I click on the OPEN or BROWSE button in the website, Open File dialogue opens trying to list the location it is already looking at, and it hangs for over 30 seconds before listing files. This is windows 11, but it did it when i had windows 10 too. I dont know what to do.

When I try to load "Comments" I get this message:

Failed loading comments! Please try again...

Trying again doesn't help.

This is a fairly recent problem

Thanks for your help.
