I'm migrating Thunderbird from my old Windows 10 computer to a new Windows 11 computer.

I've installed Thunderbird v115.12.2 and successfully moved all my accounts, emails, calendars, etc., to the new computer.

Several things are NOT working correctly, though:

1 - Settings will not open. Here is the message from the error console:

Error: No such tab mode: preferencesTab

   openTab chrome://messenger/content/tabmail.js:758
   openTab chrome://communicator/content/utilityOverlay.js:257
   openPreferencesTab chrome://communicator/content/utilityOverlay.js:295

   openOptionsDialog chrome://messenger/content/mailCore.js:628
   oncommand chrome://messenger/content/messenger.xhtml:1

2 - Customize menu does not open

3 - The hamburger menu in the upper right corner does not open

4 - The spaces toolbar on the far left is missing

5 - Events and Tasks are missing from the menu

6 - My calendar is nowhere to be found - I can't find a way to access it (on my old computer, I clicked on the calendar icon in the spaces toolbar on the left side of the window)

Thunderbird on my old computer was also running v115.12.2 when I backed up the profile folder to move it.

I tried downgrading to Thunderbird v102. I had all of the same issues listed above PLUS all my accounts and emails disappeared. -- I've brought it back up to v115.12.2.

Could someone please help me get Thunderbird working correctly?

Hi there, Im on a windows 10(ish) and yesterday got this problem after the auto update to firefox 133.0.3 - Update is not working. error window says platform version 133.0.3 is not compatible with minVersion >= 133.0... how can I fix this?

I've seen that there was a similar issue back in October with a previous version. Tried to follow instructions and reinstaled firefox from mozilla. But the problem is still there. Restarted after reinstalling and still getting the same error message. ((( Please help )))

I'm running Firefox 122.0.1 on a Windows 10 desktop PC, with a profile which includes a userChrome.css file which makes several layout and cosmetic changes.

I also have a laptop (also Windows 10) which has an old Firefox 97.0.1 installation, and I'd like to make the same changes on this machine which I'm used to on the main computer. I copied my desktop profile to the laptop, to the same directory as its present profile, but when I rebooted Firefox the transferred profile wasn't recognised.

While doing the transfer I received error messages about some of the folders: Destination path too long. This despite the fact that the registry flag to accept extended paths is set to 1. I had to skip several folders in order to complete the transfer.

Could this be the reason why the new profile isn't being picked up? Or is it because the two Firefoxes are of different versions?

I'd be grateful for any thoughts. Many thanks.

After a recent update to Firefox Nighty, the error "Procedure entry point IsWow64Process2 not found in DLL xul.dll" began to appear. I am using Windows 10 1507 LTSB.

Bonjour après avoir téléchargé firefox l'installation d ela nouvelle version ne se fait pas automatiquement sur mon ordi linux. que dois je faire? merci de votre aide

FF is my default browser. My computer is a new iMac (M3) desktop. I have used FF for several years without incident, until today. It opened normally, and then the familiar update pop-up said an update was available and invited me to re-start the browser. That requires providing admin credentials to the "Install the 'Helper tool' " pop-up, which I have done every time without incident, until today. A follow-on pop-up then asked if I wanted to allow Firefox to access other apps and devices, which I had never seen before. I said "No", and that was the end of my FF browsing experience. Every time I try to start the FF browser, it wants me to try to install the Helper tool; I provide admin creds, it goes away (fails), and the browser never starts.

I have a lot of bookmarked URLs and other browser-related data that are extremely important, and I cannot afford to lose them. Used Safari & Google & Mozilla helped me learn the location of the FF "Profile" folder. Navigated there and copied/pasted it (ends in ".default-release") to my "Documents" folder as a back-up copy. Downloaded a new instance of FF from Mozilla download page. Didn't open. Went to download folder, clicked the .dmg file, which opened a small pop-up. Followed the instructions to hold down the CTRL key while clicking "Eject Firefox". Nothing productive happened (no new FF icon). The old icon in the dock still doesn't start the app.

Would it be useful at this point to un-install Firefox (in Applications) and then try again to download a new version? If so, I would need help on how to make the old Profile folder (the back-up copy) available to the new instance.

Thank you very much.

I have finally decided to take a chance on upgrading TB from version 115.10.1 to 115.16.3 hoping that this would fix the huge delays and getting hung up checking my Gmail accounts but apparently not. Is there any hope or any answers?

Hello,

I recently migrated my sites (all were, and are in HostGator, just now we have integrated them all in one business plan).

From that point I stopped receiving emails (I am using Thunderbird as email operator). Where and what setting should I adjust in order to start receiving my emails again?

I am getting some notifications from Thunderbird: "Add Security Exception... "The Site belongs to ...

Why on gods green earth did you put this sidebar in now?? Appears with the update, not needed, interferes with the picture. Just what an inane thing to do. Now would someone please tell me how to remove it please. Or do I have to hire an engineer? This was totally unneeded.

I need advice on how to allow this update without it wiping out all of my bookmarks and stored login information.

Every time I have allowed an automatic update I lose everything and my computer shuts down.

Thank you Kharen

I've downloaded Thunderbird and got my main Gmail account but now need to add a second Gmail. Could someone please advise me how I go about this? Many thanks........Joe

Hi, I avoid updating firefox browser because each time I do it resets all my configuration parameters and uninstalls my plugins. If your product version update could do this without loosing all my setup/configurations I'd be more apt to updating 'promptly'. And, I've tried the 'save your settings' suggestion I've found on the web but that is not convenient so again I avoiding doing this troublesome workaround as I have to 'review/remember how to backup firefox configuration settings each time' and review/remember 'what plugins I've installed' so I can re-install them. Thx Firefox browser user Also, when will the browser be used as simple 'gui' rather than a 'marketing/data spying tool'? I go to the same few websites and don't do any shopping so no need for 'google spying tools' to tell the marketing people to 'what I'm looking for'. I also never, ever click on any web page ads. Please create a browser version with all the underlying 'spying guts' removed, ie a 'simply, safe gui interface' for windows like back in the 1990s.
