After a new update two days ago, Mozilla will not load. I get the error message: "ERROR: platform Version 133.0.3 is not compatible with miniVersion>=133.0 maxVersion<=133.0 Maybe try to install Firefox". When I klick the Mozilla icon nothing loads. I can't load any icon for a website. Prior to the update everything worked. I need Firefox working.

Thunderbird migration to new computer

I am about to set up a new Windows 11 laptop. The old one is a Win10 one, running Thunderbird 128.4.3 32-bit. Note I haven't upgraded to 5.2esr yet. My Thunderbird profile as recorded by Mozbackup is about 16GB - most of this is archived in Local Folders. I have 15 email accounts (using four different domains, none of them are gmail or hotmail etc) and a newsgroup.

I've looked at various answers (and problems!) around these factors and cannot see the wood for the trees. Can anybody tell me - or direct me to - a clear description of how to go about this? Some questions are:

1. Can I install 64-bit on the new laptop and copy over the old 32-bit profile? If not, is there any problem in continuing to use a 32 bit Thunderbird? I am getting a lot of hanging/not responding in the current TB. Note I haven't upgraded to 5.2esr yet.

2. How do I ensure that all the archived mail is transferred without problems? I haven't compacted anything lately, since I noticed that sometimes a message stub is retained where the message body seems to have disappeared, and that compacting risks deleting even the message stub, which can be useful.

3. I've been using MozBackup for ages now but it is really ancient - is there a more up-to-date backup that would be reliable?

Thanks in advance! I'm planning on do the new installations at the weekend but anything I can do to prepare would be useful to know!

Migrating from a Windows 10 computer to a Windows 11 computer and many aspects are not working correctly

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

tabmail.js:956:17

   openTab chrome://messenger/content/tabmail.js:956
   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?

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.

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.
