Thunderbird Support Forum

As described in [question] I am unable to install addons in Thunderbird: when attempting to install an addon, either via the in-app browser or via a file, a pop-up window appears for which "Add" and "Cancel" buttons do nothing (there is no way to move or remove the window without killing the process).

I am opening this question as this problem still persists over a year and many versions later.

Thunderbird V. 115.11.1-1 on 6.9.3-arch1-1 with Sway WM

I have set toolkit.legacyUserProfileCustomizations.stylesheets to TRUE in both Thunderbird and Betterbird.

I have created the file C:\Users\MYNAME\AppData\Roaming\Thunderbird\Profiles\r2v9k1zw.default\chrome\userChrome.css

I have successfully entered css into that file that work as expected in Thunderbird v115.12 and has for the past several versions. But I have NOT been able to do anything in that file that works with BetterBird. In fact, using the inspector, I don't see userChrome.css even being loaded! I have also tried starting the file with '@namespace html url(“http://www.w3.org/1999/xhtml”)' but that makes no difference either.

How do I get BetterBird to recognize the userChrome.css file?

Refer to two images below.

Just loaded Thunderbird on a new laptop. It displays a list of messages with no headings, each message listing in two lines and acres of wasted space in the middle. See Image 1 (6300040).

How do I get back to a list of one-line entries with headings at the top of each of the columns (which lets me change the sorting direction)? It works so much better for me. See Image 2 (6300039).

Thanks in advance for your help.

Latest Thunderbird update has placed the From and Subject fields on two separate lines in the classic view. Other views I have tried do not put these two fields on the same line which is what I have had for decades. I have essentially lost half the space I had to view contents of my email inbox and folders. How can I modify my view back to the way it was before with From and Subject on one line giving me a more compact view of things?

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.

recently I learned how to point all accounts "archive" and "junk" and "Sent" to "local folders". But, Thunderbird continues to isolate archived messages into a separate subfolder within each of my several email account(s) - I work with a unified inbox and prefer unified "Junk" and unified "Archive" and unified "Sent"... How do I do teach Thunderbird to start using the intended folder structure ?

My many message filters were lost in updating to 115, and it has taken much time to reconstruct the new layout to be usable. If this was AI generated, it is a poor outcome.

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?

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.

Hello,

I am new to Thunderbird and need help with configuring the 'Copies & Folders' tab in Thunderbird 115.12.2 (32 bit) running on Windows 10.

Background: I have just set up a pop3 account to download and locally store all incoming messages to my inbox and also to keep a copy of those messages on the server.

I want to store all sent messages for that pop3 account locally too, in a 'sent' folder.

Questions: 1. If I have more than one pop3 account set up like this, do I: (a) set up a separate 'sent' folder for each of those accounts; or (b) set up one 'sent' folder containing sent messages for all pop3 accounts, or (c) is it personal choice?

2. How do I set up: (a) a separate 'sent' folder for every pop3 account? (b) a single 'sent' folder for all pop3 accounts?

3. Can I keep a copy of all sent messages on the folder in addition to storing the locally; and if so how do I configure this?

4. How do I set up the Drafts & Templates section for the above scenario? My preference here would be to have one drafts folder for all pop3 accounts. I don't use templates.

5. If I uncheck the 'keep message archives in' check box, will that turn off automatic archiving and keep all incoming pop3 messages in the inbox?

6. Is there an up to date manual for Thunderbird? I can't find one.

Many thanks for your help with this.

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.

I would like to delete a mail without opening the mail or without a right-click.

Please refer the images to understand what I am saying.

The attached pic is from Windows default Mail app. I was talking about the red delete icon. Is it available in thunderbird too?

Thank you.

I have a <something> that creates a daily sunrise and sunset entry time in my diary. It isn't an addon as far as I can see. It's not a prewritten list, but seems to create its entries dynamically when I first look ahead to a date- filling all the days with the correct sunrise and sunset times. The normal reoccurring event options don't appear when I delete one. i.e. doesn't offer me the option to delete all the events. I have no idea what I did to set this up ( it must have seemed a good idea at a time). I can not see any subscription that would account for it. I've checked all my accounts on my devices. Thunderbird/Betterbird on my main PCs and Outlook.com on my iPhone just in case I brought it in to TB that way ( which seems unlikely). Nothing. Clearly something is working away generating new sunrise and sunset times to display in TB. But I can't find any way to kill it off. I must have found a sunrise/sunset app that does this, but I have no idea how or where. Any suggestions. Either where it might be hiding in TB or where I can track it down and look for instructions.

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!

I have a Thunderbird on my laptop with a big folder in the Local Folder. It has a labeled "mail window" having 5,044 messages in a folder named under the internals of the Profile as "Family" and "Family.msf". Under "Family" are at the next level called "Archive-A" and "Archive-A.msf". (This may not be a kosher "archive".) I tried to use NanaZip to prepare as a zip by Exporting it the other laptop's Thunderbird in our house, but the process seemed to hang before that could do it. Maybe there had to be two levels, I dunno. Maybe getting from a .ZIP to a .SBD....

Even if that had resulted in a useful .ZIP, I'm not at all clear how I could I succeed in importing it into the main profile on the other TB computer. I am defeated at this point.

I wish I had a "Thunderbird for Dummies", or at least a manual + a lexicon with acronyms.

Could someone help me out?

Thanks!

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.

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.

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!
