items dragged to overflow menu pop back out, will not stay there - dunno how to fix this.

Hate the "puzzle piece." Involuntarily upgraded to 115.25.0esr and it lost all my bookmarks, addons, history. How do I know which profile was the most recent, before the update added a new profile? How do I find my addons from the previous version? history?

I exported my profile to an external drive, then reset my Windows 11 PC. The resulting file is a zip file. When I import, the import starts, then stalls and gives an error. The error log is incomprehensible to me. How can I not lose my local folders and messages? I tried unzipping and importing that folder, but another error. I need help! Ideas? Thanks.

Image of the error attached.

Following a switch off and restart triggered I think by a Windows update, Thunderbird is not displaying any messages in my Inbox, though it is showing the number of messages in the Inbox title bar. 'Drafts' and 'Sent' all display correctly, but the 'Inbox' is blank with a grey icon of an envelope and the statement: "No message found". I am an IT novice. I looked on the 'help' pages. I have checked that no filters are set. I have right-clicked on the 'Inbox' title to display the menu with 'properties' at the bottom. I have clicked on that to bring up the dialog box with the "Repair" icon. It shows 'Inbox' in the 'Name' box but I note that the 'Location' box is blank. Presumably it should not be. Presumably it should show either the location of locally stored messages on my hard drive, or the location of the messages on the email server. I am not sure which. I have found the directory on my hard drive where I believe the messages are stored locally. The size of the file suggests to me that they are all there. The periodic 'Checking for new messages' is happening, but nothing is displaying, though a check via webmail shows that new messages are arriving on the server. What should I do to get my Inbox to display correctly? With many thanks, Iain

Recently clicked to update to the next version of Firefox. Then I get the message "Restart to Update Firefox." I restart Firefox but the message is still there when I click Help > About Firefox. It would appear that the update did not happen for some reason. Do I need to re-install Firefox to get around this problem?

I need assistance to setup my accounts correctly in my unified inbox. A few times I have lost some messages, when sending mail, they go out from both accounts Is there a way to chat with someone, and to share screenshots. I look forward to hear.

Bonjour, J'ai effacé par erreur un dossier et ses sous-dossiers directement dans ma messagerie Orange. J'ai ensuite installé Thunderbird qui voit ces dossiers dans la poubelle mais ils restent désespérément vides des mails qu'ils contenaient. Est-il possible de les récupérer malgré tout svp ?

I am now getting a spinning wheel with annoying frequency while using/trying to use Thunderbird on my MacBook Air 2017 running Monterey. Everything was fine for the first 6-9 months, but over recent months the spinning wheel has appeared more and more frequently while I'm trying to read mail, answer mail, scroll through messages, etc., etc. Now it comes up every few minutes and delays me doing anything for about 15-30 seconds at a time. It's really frustrating. I recently ran Onyx, which was designed to clear cache, etc and make everything run smoothly. But the only program it required me to quit before it started was Thunderbird. Is there some cache or something I need to clear on a (semi-) regular basis to keep it working at a reasonable speed without this godforsaken spinning wheel interrupting everything? Thanks for any/all your help.

Copied Thunderbird Profile from Windows 10 PC, pasted to Windows 11 PC - No email history or address book

I followed the steps to copy the profile from the old PC and paste it into the folder on the old PC.

Thunderbird is using that profile, but there are no email history or address book.

We recently update Firefox with version 138.0 and now getting the message "Gah. Your tab just crashed" when opening the browser.

We attempted to update and install version 138.0.1 only resulting with the same error. We also found and attempted the following all resulting with the same error: - change the about:config page for settings to false for both browser.tabs.remote.autostart and browser.tabs.remote.autostart.2

- clear browser cache.

- enable Temporary Mode in the Help menu. This appears to fix the problem but only for the current browser session. When a new Firefox window is opened, the error reappears.

What is needed to resolve this error or is there a way to permanently enable Temporary Mode or some similar setting? Thanks for all your help with this.

Opened Thunderbird today April 7, 2025 and the oldest email was from 2:58 PM April 6 2025. All my extensive collection of folders and old email have disappeared. New messages arrive in my inbox just fine. I suspect that there is a folder still on my hard drive somewhere with all the info in it. It appears that Thunderbird just can't find it for some reason. How can I help Thunderbird get back to using that file?

I created a 2nd account years ago and it has worked since then. Now when I create a third account, it works well but when I disconnect I loose the account and have to recreate it again. How come?

I would like to download hundreds of emails from Thunderbird to my PC for archiving purposes. How can I download one of my folders from local folders? I tried using AI but it didnt help me at all.

Hello,

I recently updated my Firefox browser to the latest version, 138.0.1 (64-bit), on Windows.

After the update, I noticed that when playing videos in fullscreen mode (for example, on YouTube or other video websites), the Windows taskbar (the bar at the bottom of the screen with the Start menu icon) does not hide automatically. This is affecting my fullscreen viewing experience.

Before updating to version 138.0.1, the Windows taskbar would hide correctly when entering fullscreen video.

I was wondering if anyone else has encountered a similar issue with the Windows taskbar not hiding, or if there are any suggested solutions to help resolve this problem.

Thank you for your help!

Hi all, New (ish) user to TB here so please be gentle ha ha!

I was using a 2013 Mac on Catalina and recently moved onto a 2019 Mac running Sequoia.

Everything copied over from old system onto new, however when I opend TB on the new Mac, my font is tiny and when I open a new email that is tiny too. The only way to enlarge it is to hold the CMD key and press + 6 times to get it to the size I want it.

I have been through all the articles etc to try to get it to stay enlarged, but as soon as I log off and back in, it goes back to being tiny.

Any help or guidance would be greatly appreciated!

I've finished setting up the S/MIME encryption in Thunderbird, and imported all the certificates needed. When people with the certificates emailed me, I could receive and read all the emails. However, when I replied to the same people, I got the error message saying 'End-to-end encryption requires resolving cerficiate issues'. My colleagues imported the same certificates without any issues. Do you have any suggestions for me to solve the issue? Thank you very much!

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?
