I have not changed my email accounts or my Google & Microsoft usernames or passwords. A few days ago when I started Thunderbird, two Google pop-ups arrive reading "Mozilla Thunderbird Email wants to access your Google Account" demanding that I deny or allow it. Why might this be happening and how do I stop it? This does not occur with other email apps such as Outlook for Windows.

I have seen many questions a bit like mine but they all refer to downloading emails. Mine is different: "The folder 'Trash on my@email.com' could not be compacted because writing to folder failed. Verify that you have enough disk space, and that you have write privileges to the file system, then try again." It now happens on two different email addresses (one is POP one is IMAP). Trash seems otherwise to work and can be deleted. But still this alarm. MAS OS 15.1.1 (24B91) - latest Thunderbird 128.5.2esr (64-bit)

When I use my PC (main device) Thunderbird shows individual mail folders, on my iPad the default mail client as well as individual account folders has an 'All Inboxes' This is very useful as 95% of my mail will go to one account .... so having an 'All folders' account ensures I don't miss a mail arriving on a less used account.

Is there a way to set this up on Thunderbird?

Tracking Protection

I recently encountered an issue when attempting to login to The Coventry Building Society website using Firefox (desktop PC & Windows 10):- https://www.coventrybuildingsociety.co.uk/ It failed to display the page used to enter the one time passcode used for two factor authentication.

After looking on some forums I discovered this is because 'Strict' tracking protection was enabled. If I change to 'Custom' and uncheck 'Tracking Content' then things work as expected.

I also read on a forum that you can leave tracking protection set to 'Strict' but enter the URL for the problem website under 'Enhanced Tracking Protection -> Manage Exceptions'. I tried entering 'https://www.coventrybuildingsociety.co.uk/' Initially this appeared to work. However, when I tried it again the following day, the page failed to load as before. I had to change back from 'Strict' to 'Custom' and uncheck 'Tracking Content' once again. It's as if the exception URL is ignored in 'Strict' mode.

Am I doing something wrong or is this how it is supposed to work? Do I need to click on the shield icon (to the left of the padlock icon) and turn off 'Enhanced Tracking Protection' every time I visit the website?

I had a Firefox update I believe last Friday 16th August. This resulted in a disastrous event whereby an error message displayed: error message 129. I finally managed to open a version of Firefox but I had lost all my bookmarks and open tabs. I also had to sign in to all existing websites which I had previously automatically had access to. The strange thing was that the version of Firefox that I had opened was from 2022 sometime because of the data that appeared. I am totally devastated by the loss of my bookmarks. :( What can you do to help?

I've been using Thunderbird for several years now without any issues, and I currently have the latest version installed. I typically have multiple email accounts logged in. Recently, I tried adding a Gmail account, but it wouldn’t log in, showing the error: "Unable to log in at server. Probably wrong configuration, username, or password."

I’ve tried the usual fixes like closing and reopening Thunderbird, clearing cache files, and even searching online for solutions. Based on what I found, I’ve tried turning off VPN/antivirus, changing the default browser, clearing browser data, and, finally, uninstalling and reinstalling Thunderbird after removing all my email accounts.

Now, I’m unable to log in to any of my accounts, which were working fine before. Can anyone guide me on how to resolve this issue?

Thanks in advance!

On my main Laptop I checked the Roaming\Thunderbird folder properties and found the following: Size on Disk: 35.8 GB Contains 253,172 files and 1,533 Folders. Is their anyway I can reduce the size? My TBird seems to be running slowly and occasionally stalls. I do not want to switch back to Outlook client program, I am not a Microsoft supporter. I do know I could move mail to local folders but would that mean I could only access them from one machine? Thanks.

How to stop 128 ESR is automatically updating to broken Thunderbird 131

I've never knowingly installed a non-mainline thunderbird, but earlier this week I started getting the following when I open Thunderbird:

This is an unsupported version of Thunderbird!! Thunderbird monthly releases are not considered stable for general use. Use at your own risk, this build is the same quality as Thunderbird Beta.

Checking the version of thunderbird.exe It says its v131, which happens to be the same as the copy of Firefox installed. When I remove and reinstall Thunderbird it starts off as 128 but quickly changes to 131, even after uninstalling Firefox. (Also annoyingly, this stomps on the version in the profile, which 128 claims is no longer compatible, because Thunderbird isn't clever enough to save a copy of files when it makes "breaking" changes to user files)

I wouldn't being on 131 if actually worked, but it gets stuck in the handshake with my IMAP server, and doesn't even show the local folder caches. (It also for some reason shows the window controls on left side of the window title bar, rather than the right).

How can I restore standard functionality?

I've been a Thunderbird user for years. I have no idea what they changed recently, but it's incredibly, incredibly SLOW, almost to the point of unusability. Even something as simple as deleting emails.

I usually do these in chunks -- select multiples and delete. We're not talking about hundreds of emails at at time here, just maybe 5-15. Select them all, hit delete, and it should take just a couple of seconds to delete the messages. It did, in the past. But lately, it's taking so long that I could leave and make a sandwich, and when I come back, maybe it will be done. Maybe it will still be working, though, or maybe it will have locked up because it was taking so long.

It's pretty difficult to get work done at this rate.
