Firefox Community Forum

This started happening a few days ago.

I tried to drag a tab out of the main window to put it in its own window on my other monitor, but the tab just became unselectable, and if i scrolled in the tab bar, the tab icon and text would remain locked in place in the display while the other tabs moved behind it.

The main Firefox window also lost the minimize, restore, and close buttons. The only way to make the tabs work was to close Firefox and relaunch it.

I noticed this happened only after any app in the OS went full screen, be it a steam game, or another Firefox window, or a VLC window, or anything else that I did that made an app full screen in any of my monitors.

I am using Ubuntu 24.04 with KDE Plasma 5.27.12. Kernel is 6.14.0-29. Display server is Wayland.

Initially I thought this could be a problem with the snap version of Firefox, so now I've installed the deb package, but the problem remains. Firefox is the only app which presents a problem of any kind when any window goes full screen.

Here's a video showing what the problem looks like, in case my description was not clear. The ghostly tab in this video is the chess.com home page and you can see it as the third tab from the top right of the video, and it remains in that position as i scroll the other tabs, completely unselectable with the mouse.

Any idea of what could be causing this issue to appear?

Thank you!

After tinkering with about:config (shouldn't have...) the background of every page that does not specify a body background color turns the color of my theme background color.

Using the firefox color pipette says its white, but it clearly isn't.

The theme i have is dark, making any page that expects the background to be white unreadable (without DevTools -> Body -> background-color: white)

I haven't been able to find the config that fixes it.

As of 7/10/2025, Xfinity Streaming does not open through Firefox. I much prefer Firefox to any other browser so I am a little mystified as to why all of a sudden Xfinity Streaming does not open. I receive my Comcast email through FireFox but when it comes to streaming content, the Xfinity logo just sits there and does not open.

This is both a settings issue, and a privacy and security issue. I want to disable the google lens context menu item to protect my security and privacy from constant AI monitoring. I've almost accidentally clicked the new option before and I don't want to send photos or images to google's AI unless I specifically intend to do so.

I feel like Mozilla is interfering with people's privacy more and more, taking away features from their users, adding features we don't want, butting in and telling us how our browsers should work. This is starting to become absurd. Now you've added AI into the browser that can control how your tabs are displayed and named even, a setting I found while trying to disable Google Lens.

There's a couple other settings I need to figure out how to disable too, such as the context menu of translate and the ChatGPT context menu items. I just removed ChatGPT and a new AI chat bot option appeared. Just wow. What the hell Mozilla. Is your intention to just turn your browser into one big spyware?

Give me the option to disable all of this stuff you keep adding. I have a policy thats supposed to disable your auto updates too but YOU disabled that as well allowing you to install all this malware/spyware into my machine without my authorization.

Hi, whoever may read this ...

I asked friendly & helpful volunteer @jscher2000 a couple of days ago about the Strange Case of the Disappearing Bookmarks that suddenly befell me in FF last week.

Last night, the Bookmarks came back - or came back in part, so to speak. ~ ~ There are outstanding problems. I hope these too resolve themselves or can be resolved in the near future, as it is a bit debilitating.

So, what are my current issues/problems with Bkmrks in FF?

1) Can't search my Bookmarks any more.

I enter a search term in the Bkmrks Search box (whether all Bookmarks or a defined subsection/folder I have made) - never a response but blank (though I know that term is among bookmarks somewhere) - and then, the content list of that sub-folder of my Bookmarks even goes blank when I search there. (That content list returns when I click on another folder and back to that one, but that's not much consolation.)

2) Problem adding any new Bookmarks.

Though the "Bookmarks Star" lights up when I try to add a new Bkmrk - suggesting it has been saved - the new saves are nowhere visible among "Bookmarks". Not under the folder I chose to save them to (or tried), nor anywhere else I can see under Bookmarks, such as in the general folder.

3) Can't even Export Bookmarks any more - as html or in any other format.

I go to Manage Bookmarks, etc., and click "Export as html" ,,, nothing happens. There is no trace of an exported html or other file at the location where I decided to save the file.

(To explain what may be obvious: the point of the (attempted) Exportation on this occasion is to (try to) investigate, access the saved Bookmarks, retrieve the sites, etc.)

Can anyone help - or maybe offer solace that FF might fix itself or be fixed in the near future? Like I said, it's a bit debilitating for work, research and entertainment alike.

I should perhaps add that I prefer to use a laptop (HP) where possible.

Best wishes

Please I want to remove Ai from Firefox Mozila permanently on Windows 11 for all users/profiles:

I tried a lot of workarounds but they are unsuccessfully: I tried to create extensions (Hide Gemini, AI Google Overview), but they do not work for all users; only profile-based extensions are supported. I tried to use preferences using internal settings on Firefox, but it does not apply to all users. I tried using a script on PowerShell for all users merging internal preferences, but it does not work I copied the local and roaming settings from Firefox to the Default profile, but it was unsuccessful.

I also tried to remove "All" from the search page, but I moved the seach to go to the tab "Web" only.

Website: https://www.londonpicturearchive.org.uk/view-item?i=119810&WINID=1764158938344 (for example) On Safari I see there is a message overlay from the website saying "press the command key to zoom the image". On Firefox, this message is not displayed, and the website is greyed out.

I have looked at all my settings: I can't see anything wrong. Any ideas?

Hi, I have the settings of 'General > Startup > [checked] Open previous windows and tabs' on. Most of the time it works as expected, but there are several occurrences when all of the sudden all of my pinned tabs are gone. When this happened, I usually tried the 'Command + Shift + T' to restore them. Sometimes they came back, some other times, they don't.

Can you fix it?

It's starting to get really irritating because I can have >12 tabs pinned and it's troublesome to have to remember them all in case this happens again in the future.

Thanks!

Hi, when I want to zoom in to the website page, I cant seem to find the horizontal scroll, thus I cant see the left side of the page that I zoomed in. Please make the horizontal scroll available. Thank you.

for some weeks now, Firefox (latest, in Windows) crashes, or says 'not closed properly' and shows (usually) 12 'instances' in Task Manager when only one tab has been opened. I'm not techie, and need clear advice. Can anyone help please? Hugh, UK

After a re-start, my Firefox browser on a Dell laptop lost all history and has since also not been collecting websites visited. When opening a new tab, the shortcuts and recently visited websites are also gone and no longer being collected. My CCleaner recently updated itself to a new version but I unchecked the delete history for Firefox (which treacherously is clicked by default - I fell into that trap before). Happy to blame the new CCleaner but that would not explain why history is not being collected now - to me the fault seems to lie with Firefox instead. Another possibility that went through my mind: Is Microsoft sabotaging users of Windows 11 to force them to buy new? PS: Under "Privacy", "History", the setting is "Firefox will remember history", as it always has been and should be. But it has forgotten all previous history and it is no longer collecting any new history either!

After recent update, I can not browse any addons. The site https://addons.mozilla.org does not open, shows the connection timed out. I uninstalled and reinstalled firefox deleteting all firefox related files. The problem still persists. Other than this all the using browsing I do are all working fine. Just this extensions I cannot browse. When I click the extension icon by default it shows some extensions, I can Install them. The problem is I can not browse them. Even the recomendation tab is also empty.

PS: I am using firefox on manjaro linux.

Hi! I'm on a relatively new to me (refurb) desktop computer running Win 10 Pro (64 bit)* and Firefox 143.0.3.

In the past week both Firefox and Win 10 have updated. I don't know what happened, but now when I boot up or reboot, my computer opens to MS Edge. Yuck!

Every single time I have to reinstall Firefox! Once I do that, all is well again. I have all my bookmarks back, etc.

It also keeps changing my "default to Firefox" browser setting, turning it OFF, while I'm using Firefox. I repeatedly have to keep going in and clicking to make FF to the default browser again.

Why is it doing this? How do I stop it?

Anyway, I know I can't delete Edge or uninstall it. How do I shove it back into the black hole it has lived in until now?

Thanks very much in advance for any help offered. :)

• (Nope - computer not eligible to upgrade to Win 11. My processor isn't fast enough, I think.)

I have asked this question before and followed ALL recommendations to no avail. I received no other suggestions to now, nearly a year later I am asking this question again. I had to stop using my favorite browser because of this. You all used to help your users but alas, no more. Here is a link to my previous question and then below is my present question;

https://support.mozilla.org/en-US/questions/1473866

I am running a fully updated Windows 11 computer. I have 4 fully up to date browsers; Vivaldi 7.5.3735.66 (Stable channel) (64-bit); EDGE Version 139.0.3405.125 (Official build) (64-bit); DuckDuckGo version 0.126.3; and Firefox 142.01. I play Bejeweled Blitz on FaceBook. The game works perfectly on all browsers EXCEPT Firefox. When I try to play on Firefox I get a message that says I must "upgrade to the latest version of Flash:. There is NO flash anymore. Why am I getting this message on Firefox but the game works just fine on all other browsers?

The website you are blocking is on my domain and is my website. Why are you blocking it? Stop blocking it!

After upgrading my 128 esr to 140 esr, some sites stopped opening. In regular versions, it has not opened for a long time. There are many such sites, for example, qwen3.app or temp-mail.io. It thinks for a long time and finally a message that the time has expired. Chromium is ok.

After my bitwarden add-on failed me, I remembered ChatGPT helping me with this another time - but I got it wrong. I right clicked the extensions button (I have 3 add-ons falling under that button) and removed from tool bar, thinking I could then reinstall it and the Bitwarden issue would rectify.

Instead, the extension icon disappeared, and is nowhere to be located. ChatGPT wants to do some reconfiguring but surely there's a better way. I have looked in "customise toolbar" (ie, right click toolbar, click customise toolbar and look for the icon" - but the puzzle piece icon is not there.

Surely I have hidden the puzzle piece icon somehow and I need to do some sort of magic to make it reappear... Have never had this issue with Firefox previously.
