New install of Firefox set up with a 'wrong' email account. Tried to use the 'Mozilla account' page to fix this by using secondary email and then making it primary. But the secondary email I want to use is not allowed by Firefox giving an 'Account already exists' error. What should I do?

I have Ubuntu 22.04 (on a Dell Optiplex 3000) with a minimal installation. I downloaded Firefox 125, removed the SNAP Firefox and installed this Firefox with no issue. I can run "firefox --kiosk" and Firefox runs in kiosk mode with no issue.

I have made some changes in the "about:config" part of Firefox. I have also made some changes to the Ubuntu keyboard shortcut list. There is only one user created on this system and I have configured Ubuntu to login this user automatically upon reboot.

However, if I setup Firefox --kiosk to start automatically (I use the gnome-session-properties application to achieve this) and then reboot, Firefox does run, but it does not appear on the screen. If I enter the "switch windows" keyboard shortcut (ALT-TAB), the Firefox kiosk appears.

So, is this something I can fix by changing the Firefox configuration, or is it an Ubuntu configuration change. If so, can anyone tell me what I should do, or have an idea how to debug this?

I have accidentally end up with two FireFox accounts. I want to combine them, but I can't change either account to the other one because FireFox tells me that the replacement email/account is already in use. How do I get around this?

I reset a computer, deleting all my files. I want to use, as I do elsewhere, Firefox as my browser. And though I signed into Firefox using my old credentials, none of my bookmarks are there. How do I complete this setup?

I have two Zebra TC8000 hand scanners running Android OS 5.1.1 that I've reset to factory defaults. I need to download and install Firefox but each installation attempt fails either at the download or at installation. No real detail is given as to what the issue is. I just get a message "Queueing" or "X App not installed."

I've attempted to install our regular APK that has historically worked fine. The download location is... https://download.moziilla.org/?product=fennec-latest&os=android&lang=multi The APK from this site no long downloads. The download status just shows "QUEUEING" for 5-7 minutes then fails.

I switched to browsing directly to the Mozilla FTP page and attempted to download several versions of Firefox for Android. The latest version 125.0 at... https://ftp.mozilla.org/pub/fenix/releases/125.0/android/ Here, I tried installing each of the three APKs offered here and receive the message "X App not installed" with each attempt. I am, at least, able to successfully download the APK and launch the install but I can't get the install to work.

Any clue on what could be wrong?

Recently a popup notification came up when I opened firefox on my mac. Its been awhile since I opened it and without thinking I clicked : o ~ Now I worry if it'ss ledgit? Does Firefox give a popup box in top right corner when it needs an update? I wasn't on any strange website or anything but I'm always concerned and dont remember seeing that before.

My firefox now says its up to date after it restarted ~ it's running 125.0.3

Any advise is appreciated.

I am running version 125.0.3 (64-bit) on Windows 11, and I can't check for updates and have to manually download each new version after given a popup telling me that the latest Firefox update couldn't be installed. I've tried restarting the computer, tried running the Mozilla Maintenance Service, and installing the latest updates for Firefox and Windows 11. Nothing I've tried has worked, and no other help article has helped me thus far.

Hello All,

I have recently installed Thunderbird email client which populated on its own and before I was asked for an address or Password! This may be by design which is not an issue as such. However, I noticed that none of my Laptop, WIN 10, Windows Live Mail subfolders were present.

I had imaged at some point I would have to import all my Folders and the emails from Window Live Mail using the importexporttools-3.3.2 program. I have also been made aware that sometimes the process would not be without errors. Nevertheless I forged ahead.

Unfortunately I have discovered there are odd emails missing. It seems I have two options to try and recover the missing contents. 1) To delete Thunderbird client altogether and fresh install, plus to import folders and emails again. Or 2) To repeat the import procedure by over writing, which will hopefully add the missing emails!

However, I have two questions, if I am able to over write. 1) Is it possible to repeat the import again? 2) Will the result be I end up with hundreds of duplicate emails as well as those missing emails?

Perhaps someone has experience of the outcome.

Thank you in advance.

On every new release of an update for Firefox, the update process deletes all of my saved cookies that I have established an exception for. I do this so that I don't have to continually enter my user name and password for sites that I visit regularly. The developers must change the updates so that the exceptions carryover to the new version of Firefox.

from today I cannot download my gmail to Thunderbird, I'm getting always here below error code:

“400 invalid_request” or “Access blocked: App sent an invalid request,” it means the app uses an authorization method that Google doesn't allow. Google has safe ways for you to sign in and share your Google Account data with third-party apps and sites.

Please let me know how to proceed.

Thank you
