I rebooted my laptop with both firefox windows I had open and possibly a private window too, then rebooted again without touching firefox, and now I can only restore one of the two windows. I checked my recently closed windows in history and there was nothing there at all. Is there anything I can do at all to restore that other window or is it just gone for good now?

I have lost my tabs after the recent update. They used to show all tab groups in toolbar icon as mentioned here (https://support.mozilla.org/en-US/kb/tab-groups) in manage tabs section. Only the groups that were open are retained, the groups which were closed are lost. They contained important tabs which I haven't bookmarked. I didn't see any policy of removal of inactive tab groups after certain time, any help would be really appreciated. I use the desktop app on Linux.

I am unable to access about:addons on firefox, and I don't what I should do to unblock. I blocked about:addons myself, but I don't remember exactly how I did that, and now I am locked out. Could you be able to help me out with this?

What version of Firefox actually allows you to add extensions? I'm running the most current version of Tumbleweed that ships with 144.0. Attempts to add extensions just sit there doing nothing until I close the tab. This sort of worked some time ago (I forget the version) but the inability of Firefox to allow add-ons/extensions is getting to be a joke. There are other browsers out there, ya know.

One of the recent updates changed Firefox's behaviour. It now remembers my login status to various sites when I close the browser. For example, if I was logged in to facebook when I closed the browser, I will be logged in when I open the browser and navigate to facebook.com. This was not the case until very recently (a few weeks at most). Is there a way to change this?

I have strict privacy settings, and Firefox should delete all cookies when it is closed. There are no 'exceptions'. I have 'always use private mode' checked for history. Also: I haven't changed any settings recently - something changed in Firefox.

Any advice? Thank you.

Tried to sign in to Firefox on a Linux laptop; searched for a password and finally found it under "a" for accounts;maybe my error. Tried to sync. bookmarks etc. from Android phone and it suggest two non existent menu options: Sign in and - i've forgotten; Sync between devices maybe; anyway nothing resembling either was in the menu so it is at least satisfying to know you can delete a browser with no concern that anything useful or even functional is to be missed.

Firefox always auto-fills in the wrong phone number. But I can't find a setting that contains my phone number. How do I change my phone number that Firefox auto-fills?

Hello Firefox Developers,

No pressure for this item.

I would like to request that there be an option to censor or hide the Firefox user information in the Firefox UI and in the Settings section for privacy and security reasons, especially when doing online streams or making online guides.

At least an option to either make it "l.............@..." with an eye option beside it. Like what the password field behaviour is in online forms.

It would be nice if the option were available to the end-users.

Thank you so much.

Hi, I can't seem to find an extension for this.

I have several custom search engines that I can use via shortcuts on the search bar, but I'm looking for a way to select text on a website, click the right button on it and select one of those engines in order to search that text.

I think Firefox was able to do it, but I'm only finding extensions that don't use FF's custom engines, I have to add the engines to the extension itself, manually, all over again, and that's a pain to keep synced.

Am I missing something here? Thank you.

Hi,

I am using mTLS to authenticate my computers reaching websites I manage. I imported client certificate on firefox and cloudflare is checking if the client is sending the right certificate. I am using Debian and Windows. On Debian (13), everything was working great until the version 140 ESR. I don't know why but the client certificate is not sent to cloudflare, sometime it is (when CTRL+F5) but no CSS is rendered. So I can't reach my websites. Firefox is still asking for the right certificate to send but that's all. This is weird because on the same version on Windows, with the same certificate, it is working. I tried newer version (144.0.2) on Debian but it is not working. The version I use at the moment is 128.14.0esr. Cloudflare is blocking the traffic because no certificate is sent. If I disable the rule, it is working.

Could someone help me? Feel free to ask for more details.

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!

When I click on KPN TV+ I see a message: Firefox is installing missing components, try later. But Firefox is NOT providing missing components.. Or is the problem that KPN (and Ziggo IPTV) can NOT run on Linux???

I lost all my bookmarks after updating. I couldn't restore them, and now I have to log in to all my accounts. Absolutely everything is gone. I've tried restoring bookmarks, but it doesn't work.

Firefox used to save unknown files according to the save files setting. i.e. ask where to save files. Now if opens unknown files as text in a new tab.

How can the correct behavior be restored?

Alternately, can the Linux snap be fixed to allow saving of new file types? {The procedure shown in https://support.mozilla.org/en-US/kb/change-firefox-behavior-when-open-file is not present in the firefox 141 snap.

So if you go to My documentation page , go down to point 8 and try and copy the Systemd unit file from the browser to an editor, the line returns are not preserved and instead spaces are substituted. If I copy the text from a chrome browser into an editor, the new lines are preserved. I've copied the HTML source code below.

       [Unit]
       Description=Apache Tomcat 11.0 Web Application Container
       After=network.target
       

       [Service]
       Type=forking
       

       Environment="JAVA_HOME=/usr/lib/jvm/java-1.25.0-openjdk-amd64"
       Environment="CATALINA_PID=/opt/tomcat/Base/temp/tomcat.pid"
       Environment="CATALINA_HOME=/opt/tomcat/tom11/"
       Environment="CATALINA_BASE=/opt/tomcat/Base/"
       Environment="CATALINA_OPTS=-Xms512M -Xmx1024M -server -XX:+UseParallelGC"
       Environment="JAVA_OPTS=-Djava.awt.headless=true -Djava.security.egd=file:/dev/./urandom"
       ExecStart=/opt/tomcat/tom11/bin/startup.sh
       ExecStop=/opt/tomcat/tom11/bin/shutdown.sh
       User=tommy
       Group=tommy
       UMask=0007
       RestartSec=10
       Restart=always
       [Install]
       WantedBy=multi-user.target
     

So the code is rendering correctly in the browser, but is being incorrectly copied by Firefox. Note if you copy the above from this forum across to an editor the new lines are preserved, but if you copy it from the website they are not.
