Hello,

Sorry for my bad English.

I want to know, if Thunderbird works with GMX-Freemail too. Or do I need GMX-TopMail? And if it works with Freemail, what must I look for? For any information I`m glad. Thank you so much.

Regards

Wolfgang

I have 5 email accounts stored in drive I: and 3 in drive C:, with multiple profiles (in I:(...)\Roaming\Thunderbird and \Local\Thunderbird AND the same in C:). (Windows 10). I need to move to a new PC (Windows 11), where drives are named C: and D:. I tried to use the Import/export function, but the accounts previously in I: don't appear (only the basic account shows, no inbox/sent, etc. and no data). I manually changed one of them to C: and then import again only the data. That was not possible for all the accounts and many emails (90%) are missing, also from the account were it "worked". I can find some emails in folders at the bottom of the account list, but many emails are yet missing, and received/sent not clearly defined. NB: on Windows 10 I have the latest esr version, on Windows 11 the latest NOT esr version.

So I tried to manually transfer the archives, but when copying from \Local\Thunderbird to an USB for the transfer, many files (more then 40k) went missing due to errors of copying.

What can I try?

Hello Community

Can anyone help me.

After using clean my Mac, I accidently deleted Firefox and important bookmarks. I have searching for the boikmarks folder in TimeMachine but cant find them. Any ideas please?

Best regards, Graham

I have never deleted so many emails at one time, around 500. Did I exceed the limits of Thunderbird? I cannot log on. Cannot see new emails. I have been on emailsrvr.com and did verify my passwords. Thank You

FF 148.0, Intel Mac, current 15.7.4 (Sequoia)

In the middle of a browsing session I needed to consult my substantial browsing history and found it to be gone. I quit FF using the dropdown and restarted. After restarting FF the browsing history showed only that session and the TST sidebar with many tabs didn't display so I concluded FF created a new profile for startup but using my home page. I have the profile in use at the time (profile_a) and a month old backup of it. profile_a seems to have all the expected data and the bookmarks are correct. I've hacked around within Profile Groups and profiles.ini but FF refuses to use profile_a in spite of my edits, and worse is silent about it so I'm stuck and need help.

Possible related issue: is TST sensitive to the number of tabs? I'm a hoarder and find TST easier to use than bookmarks so had about 700 tabs stashed in TST.

I have used Thunderbird for many years and and have loved it. However, recently my "Local Folders Inbox" have been extremely slow (deleting emails, reviewing an email, etc.). I have tried every suggestion that I have found without any change: reducing emails in the folder (down to about 75 remaining), compacting and repairing the folder, deleting and rebuilding all of the msf files and global database, disabling all addons, empty trash and junk, clear the cache, disable hardware acceleration, exclusion in antivirus, etc. It has become very frustrating. Any suggestions would be greatly appreciated.

I routinely drag and drop attachments out of an incoming email and into various desktop folders. However, in the last couple of days, it started creating multiple copies when dragging more than one attachment at a time AND doing it in multiples of the number of attachments. For example, if I drag four attachments over, it will save the original attachment and create three more and number them: ex. File.pdf (original) and File-1.pdf, File-2.pdf, File-3.pdf. Three file equals two copies, six files equals five copies, and so on. Dragging one attachment is fine and saving multiples via SAVE ALL works fine as well. It's only multiples via drag and drop. I am running the latest Thunderbird 148.0 on a Mac with Tahoe 26.3.

UPDATE: efforts to fix this have revealed that it's likely the release of Profiles didn't cause this problem although I speculate there might have been an inadvertent time bomb in the release. I will open a different question searching doesn't turn up the fix. If I would delete this post if possible.

FF 148.0 was running on MacOS with my profile as a folder (e.g, trb618r9.default) under Firefox. When I looked in history it was empty so I restarted FF, none of my tabs were there, and TreeStyleTabs didn't display. Investigating I see a new folder named Profiles that has a profile in it with the trb618r9.default name but not all the data in the original trb618r9.default. I renamed the "new trb618r9.default" and moved the original trb618r9.default to Profiles and restarted FF but still am not seeing the original fxxx data which still exists.

Screenshot of finder before I renamed etc. as described above shows the two same named profiles.

How can I recover?

There is a way to add a folder to a Thunderbird account that combines other folders. The one I want to create would be "Inbox and Sent emails combined". I did it in the past, but I can't remember how to do it anymore. Can someone help with this? I am running Thunderbird 140.8.0esr (64-bit) on Linux Mint.

All of the sudden can't use Hotmail through Firefox I have tried clearing cache, making sure clocks are correct etc.

This is the error page that I get. How can I fix?

Hello

We use ManageEngine's ServiceDesk plus and all has been fine until Firefox 148 update was installed.

The body of a request where we type details of a case or insert images now will not display anything. The data fields are fine, it is just the description box which appears to be iframe. Other browsers still work, but we prefer FF.

Thanks in advance - Terry

I was cleaning up my wife's email when I noticed there are a lot of messages unread and in the trash folder that ought not to be. I am wondering how to fix that for her. Example: some amazon.com emails about orders, or emails from favorite merchants or websites.

I never had this problem and only been experiencing it recently.

After turning my computer off, turning back on and loading up Thunerbird, my calendars are not displaying again. I have to keep removing and readding again.

I am using Google Calendar that is linked to my phone and pc. The phone is fine and always displayings my appointments. I am using the "Provider for Google Calendar" extension on Thunderbird.

I at first though it could be OneDrive interfering with the data, but that does not make much sense as its a calendar hosted on Google, but still I configured and checked the OneDrive.

I am at a loss and getting fed up of having to readd my calendars back every day. So, I don't know if this was an update that did it, a broken extension, etc. But, I am desperate for a solution.

Regards

TB on Windows

Prior to TB 148, OAUTH worked for POP3 access to: Gmail, MS Outlook, and Yahoo.

After TB 148 upgrade: OAUTH to Yahoo fails, subsequent log-in page also fails. Both OAUTH to Gmail and OAUTH to MS Outlook still work fine.

Rolled-back/Reverted to TB 147.0.2 -- OAUTH to all works fine, as it did previously.

Note: YahooMail seems to have other problems. But I was able to confirm successful OAUTH and POP3 to YahooMail after reversion to 147.0.2.

Created new yahoo mail IMAP (PKCE) account using Thunderbird account creation. All seemed to work well. However, new account does not receive mail from "some" other IMAP and POP accounts in testing, including from TB Pro. Strangely, mail sent from oldest POP accounts works. Mail from newer POP gmail and TBPro accounts is not received. TB 149.0b1 Windows 11
