Firefox 技術支援討論區

At some point every night, my Firefox (and only Firefox) reverts to version 111 from the latest version. This happens on 2 different Windows 11 machines.

I can only get Firefox to run again by running from command prompt with "-allow-downgrade" option and then updating again.

I usually don't notice until I launch Firefox the following morning and it gives me a message that the profile was created with an older version and to exit or create a new profile.

I've had Firefox open and then it reverts and it gives me a XULRunner error about the profile being used by an older version.

I don't have any special backup or restore software running and the physical files in my Firefox folder in c:\program files\mozilla firefox are being physically pushed to a prior version dated 3/21/2023.

On both machines, I've completely uninstalled and reinstalled and it's good for a day and then reverts.

No log entries for the reversion can be found. It's just back to a prior version.

I've never come across anything like this before and have scanned for any malware or other issue, but haven't found anything.

As per old thread at: https://support.mozilla.org/zu/questions/1365405 which has since been archived.

As of version 113, this solution is being suppressed. I occasionally see the x appear briefly on the left when a tab is selected, but then it reverts. So far I have not been able to work out what setting is overriding this function, so I've just rolled back to 112 and used the "--allow-downgrade" flag on the firefox shortcut so I can still load my old profile, but understand this is not a safe option in the long term.

I'm now running in troubleshooting mode with NO extensions.

For weeks my drives have been churning and I've been running out of resource, seeing the hour glass, graying screen, etc.

I finally closed the windows with countless tabs, disabled some extensions, and it got better, but I still have problems, even in troubleshooting mode.

Task manager still shows phantom tabs. I had 4 tabs open, it showed 7, etc.

And strangely, I now see Kaperski Native Messaging with the tabs in task manager: https://www.file.net/process/plugin-nm-server.exe.html

Closed that. Have 7 tabs in one window, task manager shows 11 tabs.

Am so confused.

How do I block the 'You are seeing this message because ad or script blocking software is interfering with this page. Disable any ad or script blocking software, then reload this page.' ?

I have been using ublock origin add-on for years without any issues. For the past few weeks, pop up videos as well as above alert message appears on several news sites. Is this a glitch with the add-on or firefox browser issues?

Many thanks!

I get an messages staing that my browser won't allow me to paste from my clipboard. I'm able to use this function in other application, Firefox seems to be my only issue. Can you instruct me how to allow the "paste" feature.

Block autoplay not working on 112.0.2. I've tried going into about:config and changing settings. Doesn't help. Also under "Settings \ Permissions \ Autoplay" shows default for all websites as "Block Audio and Video" and under Websites "About:Welcome" shows as "Allow audio and video." I've changed the About:Welcome to block audio and video. I've also tried clicking the Remove All Websites button to delete the exception. Neither works. I save changes, exit Firefox, and restart. Same settings as before, and autoplay still starts.

For several years now Firefox keeps the methodology to update in the background and then force the user to restart.

This always causes some loss.

There are multiple situations where this is not acceptable. Just to give one example: I just logged in an account and clicked to receive an authentication SMS. But then Firefox forced restart and I cannot login nor ask for a new SMS because the previous request was recent.

In my opinion this makes absolutely no sense. Is there an option the turn off this forced restart?

When watching videos on streaming services (e.g. Netflix) a "1.0" is placed in the center of the screen. How do I get rid of it? (I don't want it ANYWHERE on my screen.) Thank you for your help.

This is a relatively recent but extremely annoying problem that i have been having with Firefox on Windows PC, perhaps in the past few months or so.

When on youtube i click the maximize video button (the button next to the theater mode button) the video will normally maximize over the entire screen.

However it seems the entire Firefox browser also automatically goes into F11 (full screen mode) which is something that i extremely do NOT want.

Aside from the annoyance of the mouse-wheel-scroll being able to move the maximized video up & down, through some combination of alt-tab or windowskey+D the Firefox will sometimes exit the maximized video (to normal size) but Firefox itself will still stay in "F11 mode" - forcing me to manually exit Full Screen Mode by pressing F11.

As someone who has never used F11 mode (especially because i find the Menu Bar toolbar mandatory) its very disruptive to the general use/workflow to sometimes randomly get Firefox stuck in F11 mode, especially because i have at no point requested nor desired for the entire Firefox browser to enter F11 mode.

In other words please let me maximize videos (such as those on youtube) without Firefox going into F11 mode. I never want Firefox to go into F11 mode unless i manually press the F11 button.

Before Update: I have two different YouTube workflows on two different systems. Although I use ONE Mozilla account, I was able to get automatic sign on for TWO different systems. This meant that I was not automatically logged into the other account as long as I was on the appropriate device.

After Update: Auto-login is only working on my main system's Firefox (without new update). I now have to re-log into my production YT account manually. The reason I can identify this was after the update is because I now have an "old Firefox data" folder on my desktop, aswell as all my extensions being re-installed.

Considerations/Clarifications - I do not mean auto-fill passwords. I mean that my account is already ready to go when I access the YT site. - I use a few security extensions. I understand that these may have an impact on my browser's ability to save passwords. However, for the past 7 years, this has never been a problem given similar extensions.

    - Extension List: Privacy Badger, Adblock, Adblock plus, Adblock for YT, DuckDuckGo privacy essentials,  Facebook container, and Decentraleyes.

Any help is appreciated.

I'm currently running Firefox v 112.0.2 on Linux. I've had a theme installed for a while now that I really enjoy. It's a minimalist theme I found on github and then I topped it off with some colors that suite my desktop theme.

The ONLY issue I am having is with the dropdown menus. I can't see any of the list items and I cannot for the life of me figure out where to modify these colors. Searching has only gotten me more confused.

Photo is attached. I'm hoping that changing the text color here is an easy fix. The colors are all fine in other dropdown-ish menus, like bookmark folders for example.

Thanks in advance for any advice.

I have Dlink web cams. They are only accessable via a MyDlink app. The app is only compatible with Firefox 51 or 52. How do i get older versions running on my laptop?

For the last month or so I have had problems with Firefox using too much CPU, too much memory. This is not long after I have restarted. It soon gets so bad that there is a 3-6 second delay in anything I do. At this point I am going to have to stop using FF as it is too disruptive. Cannot place any other system changes.
