Firefox Support Forum

Posting on behalf of a user who hit the VPN inbound queue with a question better suited for this forum:

The tab bar, toolbar, and address bar placement in my Firefox Desktop browser has recently changed. I have been trying to revert these recent changes as they interrupt my current workflows.

I DO know which prior profile save contains the desired info however, it contains many files and I DO NOT KNOW which files I need for the bars to be restored. If you could provide me the name(s) of the file(s) that holds the bars data, I am probably saved, hopefully saved.

For the last 1-2 weeks FF has started saving web photo files as .AVIF files instead of whatever extension the photo actually is online. I cannot find anything in the settings to change this. I am not sure if this was caused by an update, or something I did.

I am using Win 10 64, FF is version 95.0.2 (64-bit)

Anyone have any ideas on how to fix this? Thanks.

Greetings everyone,

Firefox is my preferred browser and I really prefer the Firefox Engine over Chromium that most other browsers use.

I want to install a backup browser that runs the Firefox Engine in case my Firefox browser has a problem.

I searched a lot and I thought installing this would be the best option: https://www.mozilla.org/en-US/firefox/developer/

However, I’m worried that installing the Firefox developer edition will change my Firefox installation…

( :( :(

since yr last update i have lost all my tabs, settings, and pinned tabs, what is happening can you help me stabilize this and i can not get any o\lfd them back from history as every time i open firefox, a second window opens and then keep cycling thru all the pasty websites i have visited and i cant stop it

I have checked against other web browsers and only happens in Mozilla, within the last few weeks. I checked on multiple computers, still having the following problem. I use workspace by go daddy for my online email. I click on compose and the expected window pops to create the email message. When I get to the subject line. every time i use a space bar after typing in a word, the cursor automatically moves to the beginning of the line. This happens each time I type a new word in the subject line. NO other issue in to, cc, bcc, or main message body. This only happens at the end of the subject line. If i type in the middle with characters already on either side, the space bar does not reset.

Go Daddy tech support says it sounds like a browser problem

Thank you, Dr Steve

Good afternoon Mozilla!

Hope all is well.

I wonder if you could please kindly help me.

Major issue on my Director's laptop. He uses Firefox on a daily basis and has several bookmarks, history, etc... Also when he searches for an specific company/supplier (we have over 3000) they come up and once we are on said supplier's website the account logins are recognized enabling easy and pain-free access.

Since the major issue, Laptop had been refreshed (Microsoft Windows 10 - kept all files and apps and got rid of the explorer issue where any folder within the Laptop would crash after few seconds)... Even bringing back the old profile my director can no longer access history, nor bookmarks and when searching automatic login to supplier websites is no longer there...

I used a software called Veeam Agent to do an Image of his entire Laptop on the 10.02.2022. I would bring back the whole ISO image and hopefully things would go back to what it use to be (most likely the Folder/Explorer Issue would also come back)... however he insists in just getting Firefox going ON again...

I have created a new profile and imported/copied/pasted all info I found on Veeam... there where contents of Firefox under Profiles on Local and Roaming locations within the C Drive.

Also followed this... but it did not help...

Can you please kindly help me? Kindest Regards Paulo

When watching something on Youtube and I click on the coloured download icon, I get to be able to click on the title of the video. A blue 1 appears in the download icon. When I click again, then click on the blue 1 to watch the download. Nothing happens. The window just sits there and states 'downloading', but it does not happen. This happened last year and you managed to fix it; now Youtube seem to have blocked downloading again. Geoffrey D Dean, Australia.

I was quite unhappy with the new Firefox Proton design, so I made a CSS file and copied the following code from a website. However, I don't know what to do to (1) slightly reduce the tab height, (2) get back tab borders for inactive tabs and (3) remove the small gaps between tabs. How exactly do I have to change the following code to do so (ideally, for convenience, please just complete the code accordingly)? Thanks in advance for any support!

I cannot log in to my Google account with Firefox. I get this message: You appear to have no security keys registered on your account, and won’t be able to sign in. To sign in on this device, ask your admin about registering a new security key or choosing another second step for verification.

I am the administrator of my account on Google Workspace. I have no idea what the problem is. I have MFA turned on and I am able to log in to Google with Chrome and Edge. I don't see an option on the Google Admin security tab to create a new security key. Please advise on a fix. Thanks

Today I tried to place an online order to pickup from Texas Roadhouse, but no matter what time I chose a message said it was not available. The only selection that worked was "Earliest Available Time". Finally I called to place an order. Firefox worked 2 months ago but I don't recall which version I was using at the time.

Today I was using FF vers 97.x and later updated to vers 99.0.1 figuring that might be the problem, but it made no difference.

Later I tried Windows 10 Edge & that worked. Then tried a Chromebook & that also worked.

I've also had problems going to the Tracfone website & so have several other people. It's hit or miss with Firefox & usually it doesn't work. But Chrome or Edge seem to work for everyone.

Is this a website problem or a FF problem?

Win10 with what was Firefox 89. I had already disabled the Proton UI on this installation, because it is horrible. Today Firefox decided to update to version 91. All of the Proton UI junk is back. I tried disabling it again, but nothing worked. Doing a web search, it appears that Mozilla has disabled the ability to turn off Proton.

I then set about to rollback the installation back to version 89. I found a Mozilla link on this, went to their ftp server and downloaded the installation files for the last version of 89. The installation went normally, but when I opened Firefox afterwards, a little box popped up saying something to the effect of "To keep your History and Bookmarks from possibly being corrupted, Firefox must create new user profile." I exited out of this and Firefox didn't start. I attempted to restart Firefox again and the same box popped up again. The only way to get past it was to click the accept button.

I did so and Firefox started. This was clearly not version 89. As the UI is junk, it took several minutes to find out that this was now the latest version of 92!!!! I'm absolutely positive that I downloaded the correct file. When I look through the update history, it doesn't even show todays version 89 installation as happening. What a piece of junk.

I then spent 20 minutes figuring out how to revert back to my user profile, not the new one that it had created for me. I then did some research on what had happened. Well it turns out that you can't actually rollback Firefox, despite what Mozilla says. For a while they have added "downgrade protection" which automatically creates the new user profile and stops your old profile from being accessed by it. So unless you want to figure out how to spend a hundred hours reconstructing bookmarks, passwords, settings, etc. it actually isn't possible to rollback Firefox. Doesn't this violate some Microsoft rules about being able to uninstall versions of software from within Windows? If you try to do this with Firefox and go back to a previous version it blows everything up.

Does anyone know how to actually rollback Firefox to a previous version, so that Proton can be disabled?

version 94.0.2 (64-bit) message: "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." I can not see any of my bookmarks and I can not bookmark any page. I have: Shut down Firefox and restarted: no help uninstalled, deleted folders, and reinstalled: no help Import bookmarks from another browser: no help. That doesn't work either

What "security software" is the message talking about?

Hope you can help, because I don't want to go to another browser.

I added a plugin that enabled privacy.clearonshutdown for a number of settings and I have lost my Cache and History. Is there a way for me to restore that data? I haven't restarted my computer yet.

I was looking at other options: https://support.mozilla.org/en-US/questions/1290163 and apparently there is an index.dat thing I could use as well, but I can't find it. I really can't afford to lose yet more data after my last mistake.

Ok, so I installed Firefox today, and tried to watch Discovery+, it kept saying it was installing components to play the audio and video and never seemed to actually install them. I finally figured out it's the widevine plugin sitting there with a yellow bar saying it's going to install soon but never does.

I went through nearly an hour of troubleshooting, and nothing has worked. I tried toggling the DRM option on and off, restarting the browser and PC, reinstalling Firefox, restarting my modem, disabling and enabling the plugin itself, going to all the streaming sites I use, attempting to manually install the plugin, etc.

As far as I know, I'm not using an antivirus, I don't have my VPN on, any other extensions or plugins, pihole, or anything else I saw in other support queries. I'm just going crazy trying to fix this since it seems nothing works.

On some websites (e.g. the Guardian newspaper) Firefox displays graphics overlaying the text, making the page unreadable. Same page works fine in Chrome. Thoughts?

Firefox now requires a refresh to use every time it's opened. If I don't it keeps displaying that every page I attempt to go to has an expired https. It requests that I contact the owner to notify them of the problem and to try again. It does not connect to any webpage without a refresh. I've attempted troubleshooting mode and without a refresh, it still does not work. The refresh only lasts for about 10-15 minutes before another is required. All extensions are removed and even just attempting to go to google.com results in the same problem.

I want to change background color in Firefox from white to gray (because my eyes get tired of white)

I try to change it this way: Preferences -> Language and appearance -> Font -> Colors

But it does not work as expected on some complex web sites. All I want to do is to darken the background, but not to change color of other elenments (links, text, scrollbars).

Can I do it in Firefox ? How [Preferences -> Language and appearance -> Font -> Colors] works in Firefox? Perhaps, there is some "override css" for the entire browser?

When I login to URL

 https://www.ohiogasprices.com/index.aspx?mss=286965  

with Firefox there is a long delay (~5min.). This happens with multiple machines and locations (w/ Windows 10p and Windows 11p). This started a few weeks ago, I'm wondering if an update is to blame.

It all works fine with Microsoft Edge.

I keep accidentally muting my tabs when all I want is to click on them to switch to them.

I don't want the option to mute the tabs at all. I just simply want to switch to the tab when I click on it.

How do I do that?

My version is 89.0
