Recently updated to Windows 11 after Windows 10 stopped getting supported. After putting down several smaller issues on my own, I can encountered something I cannot fix on my own. Currently, I cannot detach, reattach, move tabs (With the exception of moving tabs with the right click menu). I could do all of these on Windows 10. I have already tried the browser.tabs.allowTabDetach setting in about:config to no success. I am starting to suspect it is a problem with windows versus a problem with Firefox because of an earlier bug where I couldn't move the windows entirely without enabling the Snap Windows function in my settings.

Is there a faster way to allow images in incoming messages? Manually copying email addresses to Tools/Settings/Exceptions is a chore when processing a lot of mail every day. If there's maybe an extension/add-on that would be great, though I can't find one.

Many thanks

if I type a hyperlink into the Calendar description field it does not link to the url.

The mouse pointer does not change from a cursor to a pointy hand when I hover over it

I have also tried using the 'Link' button and that creates a blue/underlined url like a traditional clickable link but the result is the same as before.

Please help troubleshoot the problem, at the moment I'm having to copy and paste every link which becomes tedious when there are lots of links

Thanks

I recently updated to 147.0.1, and now it seems I can no longer access word/excel/powerpoint files for online editing. I have already tried clearing cookies, disabling adblockers, disabling tracking protection, running in a private window, all the way down to completely reinstalling Firefox 147 fresh. This has persisted for roughly a week, so it does not seem to be an issue with my own network connection, nor with Microsoft's services, nor my files specifically since I can edit the files online from my PC at work. The error message specifically reads:

We can't connect to the server at usc-excel.officeapps.live.com (or usc-word-edit.officeapps.live.com or usc-powerpoint.officeapps.live.com, respectively).

I could previously access these files to edit when I was still on Firefox 146, so I'm guessing it's something going on with 147. Has anyone encountered similar issues with Web Office apps, and perhaps found a resolution?

Hello, I am still running an old WIn 7 media center because I have applications I need that are no longer supported elsewhere. Firefox ESR has been working just fine up until the most recent update - which repeatedly fails to install each time I start Firefox. Is there a location where this update resides? If so may I know this location and procedure to eliminate this errant update? Thanks!

I am not able to send emails I have checked all my SMTA settings I am running version 147 and this just began on 1/26. I have turned off anti virus, run in safe mode and nothing works. I can send emails from my phone and using the provider webmail but not on my laptop. This is the msg I get

' Sending of the message failed. The message could not be sent because connecting to Outgoing server (SMTP) promail.ptd.net failed. The server may be unavailable or is refusing SMTP connections. Please verify that your Outgoing server (SMTP) settings are correct and try again.

After installing thunderbird, It takes me hours to figure out that my fonts are too small because of one value in Settings > General > Language & Fonts > Fonts > Advanced > Fonts for Other writing systems gives a too small number.

It seems insane and I don't think users can easily get there. Maybe some users want to set different fonts for different languages and the "Fonts for ..." is for them. However, for most users who just want to change their font size, I don't think it's a good experience to going so deep and find an option in the loooong "Fonts for ..." list.

So please give users a simple option where I can just set my font size without such pain.

I know there's a font size option in TB menu but it doesn't work as expected. In my case, the font size shown in TB menu is 16 while the font size of my plain text emails is 12. And 1. email font sizes will change to TB menu size as long as TB menu font size is not 16. For example, when changing TB menu font size 15 -> 16 -> 17, email text just suddenly goes from 15 to as small as 12, and then from 12 to 17. 2. email font size seems changing with the TB menu font size. However, email text font size will go back to what it was when open another email.

In einer frischen Thunderbird-Installation (getestet mit 140 ESR und 147) funktioniert der manuelle globale Abruf per Shift + F5 nicht mehr für POP3-Konten.

Konkret: – POP3-Konten sind korrekt eingerichtet – „Beim Starten auf neue Nachrichten prüfen“ aktiv – „Alle X Minuten auf neue Nachrichten prüfen“ aktiv (z. B. 2880 Minuten) – Thunderbird ist online

Erwartetes Verhalten: Shift + F5 bzw. „Alle Konten abrufen“ prüft die POP3-Konten und holt neue Nachrichten ab (wie in früheren Versionen).

Tatsächliches Verhalten: – Shift + F5 bewirkt gar nichts – Kein Abruf, keine Fehlermeldung, keine Statusanzeige – Gleiches Verhalten bei „Alle Konten abrufen“

Wichtig: Der Abruf funktioniert sofort, wenn man per Rechtsklick gezielt ein einzelnes POP3-Konto → „Nachrichten abrufen“ auswählt.

Das zeigt, dass – Server erreichbar sind – Konten korrekt konfiguriert sind – das Problem ausschließlich den globalen manuellen Abruf betrifft

Zusätzlich scheint Shift + F5 inzwischen nur noch Konten zu berücksichtigen, die für den automatischen Abruf vorgesehen sind, wobei dies selbst bei gesetzten Haken nicht zuverlässig funktioniert. Dieses Verhalten ist weder dokumentiert noch für den Benutzer nachvollziehbar.

Fazit: Der bisher etablierte Workflow „manuell alle POP3-Konten abrufen“ ist in aktuellen Thunderbird-Versionen faktisch nicht mehr nutzbar. Für langjährige POP3-Nutzer ist das eine massive Verschlechterung der Bedienbarkeit.

Ist dieses Verhalten beabsichtigt (Designentscheidung) oder handelt es sich um eine Regression? Falls beabsichtigt: Warum gibt es keinen Ersatz für den früheren selektiven/globalen Abruf?

We hate this useless so-called feature and you've completely failed to give us an OFF switch! It's been many months with countless complaints and still no OFF switch! We've had this conversation before, all of your ideas must come with an OFF switch, especially so for the dumb ones like tab pinning! You don't ever force this dumb crap on us, ever!

Where is the fkin OFF switch already!?!?!?

Through extensive troubleshooting, I am unable to get firefox to open at all.

I've done a full uninstall, cleaned all user directories, program files / x86, program data, appdata roaming and local, etc. I used the Microsoft uninstaller and even Revo Uninstaller to remove everything related to Firefox, did a restart and reinstall of the latest one and it still won't launch.

Firefox was previously working until a reboot occurred and now it won't launch.

Firefox 32 bit seems to work when installed, and running Firefox as an admin previously worked but no it no longer does.

I looked at the following articles: - https://support.mozilla.org/en-US/kb/firefox-wont-start-find-solutions - https://support.mozilla.org/en-US/kb/profile-manager-create-remove-switch-firefox-profiles - https://support.mozilla.org/en-US/kb/profile-manager-create-remove-switch-firefox-profiles#w_start-the-profile-manager-when-firefox-is-closed

There's no malware on this machine (business EDR on it, even disabled it as a test and it still didn't open).

I was able to launch the profile manager but now I am unable to as the processes launch in task manager and then within 5 seconds they close.

Firefox is not running in the background for any user (I'm the only one logged in after a reboot as well)

I'm unable to open in troubleshoot mode either. Tried run as and admin cmd "C:\Program Files\Mozilla Firefox\firefox.exe" -safe-mode

Ran SFC / scannow / DISM restore health commands as well and both came back fine / no integrity violations

Hi, I don't understand why I can't access the Accor Hotels website using my preferred browser, Firefox. I'm using an iMac with OS Catalina v 10.15.7 and Firefox 147.0.1 (64 bit)

I can access the site using Chrome. Chrome version is 'This computer is using macOS 10.15. Learn more Version 128.0.6613.138 (Official Build) (x86_64)'

I've checked every Firefox setting I can think of, passwords etc. but the site freezes. Please see attached screenshot. Accor tech support say they have no problem at their end.

Other sites all seem to work ok.

Any ideas pleas on why just this website and how I can access it without having to swap browser?

No messages show up in the inbox. If I run Thunderbird in troubleshot mode all the messages in the inbox show up. I suspect it might be something regarding filtering, but I do not know how to turn filtering off. Help.

I run my BTinternet mail account via Thunderbird and would like to run my two Gmail accounts via Thunderbird too. Do I just do that by clicking on the + New Account button, please? I'd hate to lose access to my BT mail by doing that. (Switched to Thunderbird from Outlook a year ago and have never regretted it!
