Thunderbird Community Forum

Is there a way to change the default font color for replies in Thunderbird? Nothing I do works, and it is a real pain to have to manually change the color every time I reply to an email.

Thanks.

Thunderbird display messages in boxes arranged horizontally accross the top of the screen. How do I change that displAy to a list of messages listed from the top of the page to the bottom

My Thunderbird does look strange, though it works alright. It annoys me, there are black-gray rectanguler spots left top and bottom. It dissapears when in full screen mode. It is not in any other program. I add a picture. Is there anybody who knows how to solve this. Thanks, Hans, Netherlands

Not sure if I picked the correct topic for this...

I had to reinstall Windows 11 on my PC as the old copy was corrupt to the point I could not install updates, even with Microsoft's help. Before I made the plunge, I used Tools -> Export to create a zip file on my D:. After installing Thuderbird on the rebuilt copy, I went to Tools -> Import to recover everything.

About 19% in, I received error "Import failed unexpectedly, more information may be available in the Error Console." I found the Error Console but don't know how top proceed.

I have an image copy of my old installation. Can I simply locate the Thunderbird profile on the backup and restore it?

I keep getting alert notices on my phone from thunderbird. It started when i was going to add thunderbird to one of my other devices. But i changed my mind and deleted it on that device.

I need help. How do I troubleshoot TBird asking for a password that disappears when I go into troubleshooting mode? In other words, I can enter anything in for the password, or dismiss/close the pop up box, and nothing is effected by it. I still get all me email for all accounts. The only thing at the top of the box is a user name (pmruzicka). At this point, I have deleted the accounts that used that user name, including all info for the outgoing servers (even tho this password request pops up at TBird start). I have Disabled ALL extensions one at a time and the pop up still happens. I have set TBird to default them,e - pop up still there. I have unchecked the hardware acceleration box - pop up still there. I have no clue what else I could do at this point. I do NOT have a Primary password set. Can someone please help me figure this out? Getting tired of having to click off that pw box every time I start TBird. Thanks. Also, this has been happening through the last few updates of TBird.

All of my emails are being marked as read immediately. I have that option turned off in settings on all devices. I am not using bit defender. This only started after I moved to a windows 11 computer. I only have one account. I have read the previous forum similar issues.

I get USA TODAY Daily Briefing by email every day. For some time it's been duplicating stories and ads in the same message. This does not happen with my iPhone. I have used AI to try to fix the problem but to no avail. Any suggestions for how to fix?

I have not being able to add this 4 account to thunderbird: hotmail.co.uk/ live.co.uk/btinternet.com/gmail.com. I keep getting error either cannot connect to server or username and password wrong. I have managed to add two accounts successfully. I don't quiet understand what is happening with this new 153.0.1 version. I has it working before I had to reinstall windows 11 PRO. Could you help me please! Thank you! Best regards, Jairo Goncalves

I have a rather intriguing issue with the message editor which isn't a problem but puzzles me.

I monitor a number of email accounts. When compiling a message using one particular sending account the line spacing in the editor is reduced, as in the second attached image. If I use any of the other accounts it is correct, as in the first image . In each case the line spacing of the message that is actually sent is correct.

It's obviously not a big issue, but I'm struggling to understand how the editor can change depending on the sender account. Any ideas?

I have been shifting my email platform from Comcast to the new Yahoo platform. This has worked for my iPhone and for my Thunderbird app on my iMac. But NOTHING works for this on my MacBook Air. My gmail is fine, but the only way I can get to my new Yahoo platform is to sign in via the web browser. Thunderbird will not configure for the MacBook Air, and I've tried 10-15 different things already (not an expert by any means). I have all the proper settings. I have reinstalled Thunderbird on the latter machine.

thunderbrd version 153.0.1 64bit windows11 Spamfilter problem

my contacts are all in the personal address book convinced they get filtered as NOT SPAM, recently some addresses out of my adressbook get filtered anyway - weird an expert told me to setup a whitelist as a subfolder: I did but same prob... as far I know the address book works like a whitelist anyway, no success also not long ago thunderbird had an update - and it feels since the dodgy filtering started. Using thunbderbird for ages - never had that prob ever - till recent

Is there any known solution please ? Thanks & regards Jochen

I need a filter on a message to FULLY FINISH before a next message starts to be filtered. The "help" (quotes because it's an abyssal crap) says that simply ending the filter with Stop Filter Execution does it - but that's simply NOT TRUE: calling a console program in the filter, I can see five DOS boxes opening at the same time with five messages matching, i.e. the filters on the next message DID NOT wait! So... what can I do??

All of the above is because I'm getting "Too many simultaneous connections on the server". I'd like to limit the concurrency, but it only seems to be possible in IMAP, while this connection is a POP. Why only IMAP??!

Last week I deleted about 600 emails from the inbox, leaving about 500. I shut down the computer for 5 days then rebooted. TB seemed to start up ok. I deleted the remaining 500 emails. Emptied the trash folder. Tried to pull new emails to the inbox. I usually receive 100 - 200 emails per day but could not receive any this time.

I updated my Mac to Tahoe 25.5.2 recently. After the update my e-mail – Thunderbird- would no longer work. I was able to connect Thunderbird to the my university gmail account and can now read my e-mail, but I am unable to send e-mail from Thunderbird and I get a request for a password. When I enter my University password, I get the same message back. I only have one University password. What password is it asking for? The help lien at the university if not of any help. The segment below from University material point ou that I do need a second password. Where do I get it from?

2. If you are a UMN Google (Gmail) user sending from a desktop client like Thunderbird, you must use the authenticated relay smtp.gmail.com and sign in with an active Google account plus a Google Desktop/Mobile client password (your regular UMN password may not work for this).

Right click not working on spam email

Lately I am getting spam with from addresses I can not use the right click on to copy the email from address for reporting purposes. I have to use the More option, View Source and then search for the From address and copy it from there. Can this be fixed?

I saved off the source if someone wants to see it.
