Thunderbird Support Forum

I am considering moving to Thunderbird from MS Outlook. I want the rules I have already setup in Outlook to work in Thunderbird. Is this possible & if so how do I make it work.

Trying to all threads to come up when I click on a new email as a default. Already did this:- settings>general - scroll down to config editor - enter mailnews.default_view_flags and change value to 0. Does not work!

Hello,

I am running Thunderbird 115.12.1 (64-bit). I somehow turned on the number of messages and folder size and can't seem to figure out of to remove them. A colleague suggested I click the 3 dots to the right of the "New Message" but I don't see them at all. Please advise. Thank you!

I filter messages to move spam to my trash folder. I don't use the spam & junk functions.

I'm on some oddball's list who sends all their spam in bold italics and an uncommon font.

Easy to spot but it's easily 30 a day. I'd love to filter them. I don't see a 'by formatting' option.

Any ideas? Thanks!

Would you please help me permanently remove cache2 folder from Local Folders please. I'm using Thunderbird 115.12.2 (64bit) on esr channel with Windows 7 Ultimate Service Pack 1 OS.

I don't want Local Folders / Cache2 folder (or incidently Inbox, Drafts, Archives, Junk, Deleted and Outbox) but Thunderbird highlight - right click - delete button doesn't get rid of it. I can temporarily delete the Doomed and Entries sub-folders with right click - delete - delete folder but they move to Deleted folder where once again they can be deleted the same way but when restarting Thunderbird they are back under the cache2 folder again.

Even after exiting Thunderbird and directly deleting the cache2 folder(s) in system AppsData - Local and Roaming Thunderbird profiles the cache2 folder (with persistent sub-folders) returns to my Local Folders when restarted.

If ignored I eventually end up having a cache2-1 folder etc.

Using TBird 115.10.1 64-bit on Windows 11. For ease of reading text in mail I am composing, I would like to select a large font size. In Settings | Fonts I chose Arial 18; but for some reason I get a small monospaced font whenever I start a new message. I can enlarge it with Ctrl-Plus, but it reverts to its old ways for the next new message. How can I make the change stick?

Like all of us, I get bombarded with spam emails. So I set up filters to separate the "definitely spam" from "possibly spam". I've been doing this for many years now. But recently, maybe for the past few months, I'm finding that these blacklist filters aren't working anymore. The filtering failure seems to be getting worse as time goes on. And, yes, I do a match on "any", but that still doesn't work. As I said above, my filtering rules used to work just fine, but possibly a new Thunderbird update several months ago broke filtering?

Also, is there a way for filtering on the message content URL? I find that sometimes that's the only way to distinguish spam.

This there a "Global" Message Filter Rule where you can change an Apply Filter When: to ALL your Message Filters?

Example: I'd like to add "Periodically, every 10 minutes" to ALL my current Message Filters. Currently, it looks like I have to Edit each and every one of them?

Thank you in advance.

See the previous, now archive post about it.

If this option makes emails sent from Thunderbird to any other email client have arbitrary line breaks where the line changes in the view of the composer. Please explain to me like I am 5, why is this ON by default? I just spent hours wording and formatting a work email vital for my career just to find out it will most likely look like a poem to the person that reeds it. This mailnews.wraplength "feature" looks a lot like is there to signal to other non-Thunderbird users to use Thunderbird. I really really hope there is a good explanation for why `mailnews.wraplength` exists and is on by default.

The default attribution line created by Thunderbird when replying doesn't work well when sending e-mail to Outlook users. [Unfortunately, Outlook users comprise 100% of the people to whom I send emails in TB.] TB's default attribution line causes Outlook OWA to hide the entire reply from the reader unless they click on a [...] button to show it. Then when displayed, the entire message is quoted/indented.

Yes, this is a bug in Outlook. No, it's not going to get fixed.

This can be avoided by changing the attribution line which current defaults to:

       On <date> <time>, <name> wrote:

Simply adding a space after the colon at the end of the line "fixes" the problem, but it's annoying to have to do that manually.

Can that attribution line be configured somewhere?

I've found all sorts of addons that let you muck with the headers of replies, but the headers are fine. It's just the attribution line that needs to be fixed.

So... just upgraded to 115.12.2, and I'm seeing that the columns have been removed -- and I don't see a way to re-enable them!

So on the main view, we now have a line.... from address with subject below, and then to the far right, the date/time.

Is there no longer a view with columns that we could more easily see, sort, move, etc?!

Example of new view is attached.

Hi there I must say having used Thunderbird for probably ten or more years that V115 has been a big pain in the butt to get used to. Why change everything? It was fine before.

OK I can get used to a completely different layout and changed menus even though I don;'t want to but I cannot figure out how to change the background from solid black which I hate. I have spent several days on and off looking for an easy way to do this and can't find it.

So now I go to write an email and the black screen doesn't show anything with black letters of course?? What is the reason for this? So I have to change font over and over to white color.

When I read new emails no problem background is white and font is black like a normal screen. Who had this bright idea?? Please give me a simple solution not involving Css whatever programming such stuff I cannot figure out and don't want to learn. Thanks so much

I don't seem to be able to self help very good anymore, can someone please take the time to teach me / guide me through the steps ?

1. 1 can I set up Thunderbird to receive my Gmail email, and if so, how do I proceed?
2. 2: How can I set up Thunderbird on my iPhone?

I appreciate your time!

I can not get thunderbird to stop opening a web page on start up. Deselect the "when thunderbird launches......." but it is turned back on once I close and restart

It actually opens my browser and opens a thunderbird donation page.....

why is there no back button on thunderbird? I clicked on a message (have to click twice on it now in the lousy upgrade I was forced to use), and now I can't go back to the inbox. What's up????

I would like to know what the options below, contained in the settings editor, are for and how I can adjust them so that every message sent is configured to require confirmation of receipt by default:

mail.identity.default.request_receipt_header_type mail.identity.default.request_return_receipt_on mail.incorporate.return_receipt mail.receipt.request_header_type mail.receipt.request_return_receipt_on mail.request.return_receipt mail.server.default.incorporate_return_receipt
