I recently updated from a very old version of Thunderbird. The new version no longer shows the little popup messages at the bottom of my screen when automatically checking accounts for mail at the designated interval. As I have numerous email accounts (all set up as POP mail), set to check at different intervals, these popups were useful to me - they also showed when I manually checked an account, or all accounts - this also is not happening anymore. Have they been discontinued, or is it possible I turned them off? I did change some things to suppress nags to update Thunderbird during the time I was using the old version, and unfortunately didn't keep a record of those changes. I'd appreciate knowing which function in about:config controls this feature so I can check to see whether it's set correctly. Thanks!

Thunderbird causes my machine to 'hang' from time to time,

1. often for up to a second and usually a number of times in quick succession on each ocasion. Sometimes this happens frequently - say every 5 or 10 minutes - sometimes only after an hour or more since the past occurrance.

2. My machine hangs completely - nothing will work, mouse, keyboard, sound, other apps etc. If I happen to be typing (into any app - including Thunderbird - when this happens, input ceases, the cursor freezes and - if the problem persists for a second or two, Windows reports "[app] is not responding"

3. I cannot be certain, but I believe the problem occurs whilst messages are being retrieved.

This is a very serious problem as it means that I can never leave TB running as the problems it causes are not acceptable.

4. This means I cannot deal with incoming messages without periodically re-starting TB - which is an utter PIA.

I am running Win 11 Professional on a 2-year old machine with 64 Gb of memory. I have run TB in Troubleshoot mode, I have confirmed that the problem occurs regardless or whatever other apps are running (or none) and I have proven conclusively that no other app causes any kind of similar problem.

Looking forward yto hearing if others have had the same issue and what can be done about it.

I have been trying to add my accounts to Thunderbird and had good success with gmail but wasn't able for Microsoft accounts. As I said in another thread (can't find the message anymore), I have 2 microsoft email account (one live.ca and one hotmail.com) and they both don't work. I was able to add them in Outlook desktop app and EM Client (a non open source software i'd rather not use) through IMAP with success. IMAP is activated in both accounts and as per Microsoft documentation the server is supposed to be outlook.office365.com on port 993. eM Client magically discover IMAP settings to imap-mail.outlook.com instead. Thunderbird opens an OAuth page and then it redirects from microsoftonline.com to localhost and fail with "Unable to connect".

2FA not activated in one account, if that matters. I have nothing running on port 80 if that matters.

For the past.. month I would say, any time I try to use Youtube on my Firefox Browser it nearly always switches over to landscape mode after watching a video. It doesn't matter whether my phone screen's auto rotate is on or off it still does it. Yes. I already tried to turn my auto rotate on to switch it back to potrait mode, it still won't work. The only solution I currently have is closing Youtube all together from my Browser, which really REALLY sucks!!

Can someone PLEASE look into the glitch?!

I am running Thunderbird 140.9.1esr on openSUSE Tumbleweed.

For a long time now, Thunderbird often runs at high CPU (80-100% of one core), for several minutes at a time (5-10 minutes). This seems to happen many times every day, with no apparent cause from my end. (I just got back from Lunch, and the fan on my laptop was going crazy because of the high CPU.)

What can we do to identify and fix this issue?

When I try to open Thunderbird it keeps giving me a message that it is trying trouble install a new helper tool and asks for my password. I do so, hit the Install Helper button, and then nothing ever happens. I get a spinning beach ball and it never opens no long how I wait. I would be very grateful for any suggestions or advice on what to do.

All of a sudden, Firefox for Android has been using about 1GB of data daily. My Data Usage monitor says it is almost all Foreground data.

I barely use Firefox for watching videos or streaming anything, especially when not on WiFi.

I run two extensions — Privacy Badger and uBlock Origin, both of which I would assume should be saving me data by blocking ads and trackers.

Data collection settings are set to Off. Autoplay is blocked for audio and video. Stories (sponsored or not) and sponsored Shortcuts are disabled. Tabs open for 2+ weeks are automatically moved to Inactive.

which says "Sending message failed The message could not be sent connection to server SMTP timed out."

This is a new occurrence not experienced before?

If I go to webmail it will send OK?

Firefox runs some sites slows on one of my Windows 10 computers.

I'm running Firefox on 4 Windows PCs and 3 of the 4 work just fine using the same synced profile.

Fidelity.com and Amazon.com are 2 of the sites that are very slow to load. They will eventually load, but clicking on any links causes another slow load.

The same web sites are fast when I use MS Edge.

Troubleshooting steps I've taken (none of which have worked):

  • Refreshed Firefox
  • Created a new profile
  • Uninstalled Firefox leaving my old profile
  • Completely uninstalled Firefox and deleted my profile

Any thoughts on troubleshooting steps to take?

I started getting this message when I attempt to download my email to Thunderbird:

"Unable to write the email to the mailbox. Make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox."

I am using AOL with the address: rc.woolfenden@verizon.net on a Windows 11 platform with a 1TB solid state hard drive. I have never encountered this issue before.

Have an AT&T email account on 3 computers. Two of them running windows 10. One mqchine running windows 11. On the windows 11 machine, we set up a new email account and it doesn’t work. Sometimes you cannot send or receive. We delete that account and create a new one and sometimes it receives but does not send. It asks us to retry or enter a new password. We enter the password and still fails to authenticate. We tried setting it up as POP other times as SMTP. Still fails. Sometimes we get a yahoo pop up to help us set up the new email account but most times that yahoo pop up does not appear. We tried to match the setting of the windows 10 computer exactly and still doesn’t work.

Sometimes we get it to work using the above methods but fails after 1-2 weeks.

Any insights?
