Last week Thunderbird did an automatic update, this is not unusual BUT since then every time I try to start Thunderbird A message comes up

"Your computer needs to be restarted to complete a previous upgrade of Thunderbird. Do you want to reboot now? Yes No"

No mater how many times I allow the computer to restart Thunderbird never opens.

I like Thunderbird I is my preferred email reader and writer.

i've tried to import my data because i have moved to another computer, i tried importing the profiles folder yet nothing happened, so i tried deleting the profiles and it's now broken.

i've tried the password thing, didn't work and the profile one didn't work either.

FirefoxからGoogle Chromeの設定が感染したかのように変更された。 誰か特殊画面で音声をRealtekに戻す方法を教えてください。

ブラウザのマークを右クリックしたら５回連続で出せたので 音源を変更してしまったが、 変更後には特殊画面が出てこなくなり変更を治せない。

The settings in Google Chrome were changed as if they had been infected from Firefox. Can someone tell me how to restore the audio to Realtek on the special screen?

When I right-clicked on the browser icon, it appeared five times in a row, so I changed the audio source, but after the change, the special screen no longer appears and I cannot undo the change.

Hi. I have over 20,000 messages in my Inbox. I've been sometimes having trouble moving messages into folders, so I thought it would be a good idea to reduce the number of messages in my Inbox. But I can't delete or move messages in the Inbox. When I select messages and enter command to move them to a folder, or ask to delete them, nothing happens. I am a Thunderbird supporter, and I love this program. Thanks for your work! Any advice appreciated. Connie

I’d like to know how to stay in private browsing in Firefox full-time, like other browsers. It seems that my history is always saved because your browser doesn’t give clear instructions on how to stay in private browsing. It makes you you tab over to private after hitting the + button.

I've been using Thunderbird email for a few years. I use many folders to organize my emails. Recently, when I attempted to move emails from my inbox to a folder, the emails returned to the inbox. It doesn't happen with all the folders, but it is happening more frequently.

What can I do to fix this?

Hello, I have Firefox installed on my pc which is running Windows 11 pro. I also have it installed on my iPhone 16 pro max, m4 iPad pro, MacBook Air & Android tablet. I recently deduplicated my bookmarks on my pc but the change never synced to any of my other devices. I tried signing out of my account on my phone earilier today, by disconnecting & reestablishing sync but it did not help. What might I try to rectify this situation? Please note: I am visually impaired, so If images must be posted, please insure you include alt text.

Thunderbird has worked fine for me for years on my Windows 10 Pro machine. The computer works perfectly otherwise--and has a large amount of RAM. But a few weeks ago, Thunderbird started freezing (stops responding) at some point while I'm writing a message.

What happens is that I'll start to write an e-mail message in Thunderbird, and at some random point (from a few seconds to a few minutes) it will stop adding what I'm typing, and soon the text that it was showing grays out. It will then say Thunderbird has stopped responding, and I have no other choice than to close Thunderbird. I have no way of saving or recovering the message I had been typing--very frustrating!

As a partial work-around, I found that if I click on "Save" every time I add a little more to the message I'm trying to write, then at least when I restart Thunderbird I can go to Drafts and recover the message (as it was the last time I clicked "Save").

Thunderbird still works fine for all other functions (reading received messages, etc.). It only has the stopping responding problem randomly when I'm trying to write a message. It can happen while I'm typing--or during a pause between writing sentences. And the timing of the problem is very random and variable (from almost immediate to a few minutes). I tried running Thunderbird in Safe mode, but the problem was the same...

I always keep up with Thunderbird updates. Currently, I'm using version 140.1.1esr.

Can you give me any help with a solution? This problem is maddening!

Thank you,

Vincent Andrunas

Have 2 accounts in a TB install: gmail and outlook. Use outlook as my primary sending account. All mail received on outlook account is FORWARDED to gmail account. Have been asked several times this morning to either login to Microsoft account or enter a new password. Entered my "regular" Microsoft/Outlook password when asked and told TB to save it. Still getting authentication problems. Password I am using WILL log me into the Outlook website. Any clues?

Not a huge problem, but VERY FRUSTRATING! After years of reliable performance, my personalized incoming mail notification sound (wav format) suddenly stopped playing. The 'test' function in settings works fine, but NOTHING happens when actually downloading messages. I've tried EVERY possible FIX, but NO LUCK. Any suggestions? Thanks

Ever since this month's Windows 10 update I've been having problems with Firefox. I start it, the menu bar and tab comes up, but then nothing. I can't access any web sites. I tried removing the Windows update, then tried uninstalling and reinstalling Firefox, and then messing with the settings. In each case Firefox would work for a couple of days, then I'd have to start it three or four times to get it to work, then it wouldn't work at all. I've been using it for 10 or more years now (four on this computer) and have never had any problems before. I'm loathe to switch to another browser, but if this can't be fixed I won't have any choice. This is what happens when I start the program.

I've read everything apropos here, tried everything, and I'm lost--and totally screwed--if I can't get into my old Thunderbird. Spectrum, computer died, nobody competent here to get past "Registry Error," I guess, but I need all the data, contacts, calendar, etc., in the T'bird I've relied on for MANY years. PLEASE help. I tried to get a screen grab: It didn't work.

This is the second time I've appealed for help.

I received an email, Thunderbird on my Windows 11 PC, that was heavily covered by an unknown solid black design. Most of the text was covered over. I was unable to remove the blockage. When I opened the same email on both my iPhone and my Yahoo mail account, there was no problem - no blockage. It looked somewhat like a large black mask laid over the text.
