I've been using Thunderbird version 155.0 with only a few issues (reported in other posts).

To investigate one of the issues I've had to create a new profile for testing. I've managed to set everything up except for my default font for outgoing emails. If I send an email with say, four lines of text, I can format each line to be a different font and the received email reflects the different fonts for each line.

But Thunderbird isn't remembering the last selected font. So if I send a second email (without re-selecting any font) the recipient receives it in some naff mono-spaced font. I guess there's somewhere where I can set up the default font for my outgoing emails but I haven't managed to find it yet. Can anyone help?

Hello, this is the basic problem:

The short version is that there is a problem with Firefox not interacting with the scrub bar and volume bar. (all other controls work fine) We know it's a Firefox thing because everything works with Brave. (or an interaction between Firefox and the OS at least, Firefox is heavily involved)

There is more detail and we have done some work on it here: CashyOS forum post

You can use the Firefox manifesto V0.2. video for an example, as it displays all the above problems for me.

I can get you guys whatever other data might be needed, but I kinda need an idea where to look to try and fix this, as all the other posts I have managed to find don't seem to have similar enough issues to work.

When using the browser on the newest update on the android app, I am unable to interact with pop up menus, such as when I want to change the options of a search, and I can't give websites access to my camera because the allow pop up button doesn't work, the only thing I can do is tap off to the side of the menu to make it go away. The only fix to this I found was installing an older version of Firefox, ver 150.2 specifically.

Firefox Add-ons Store returns HTTP 406 Not Acceptable on direct connections, but works through a proxy

Hello,

I would like to report an issue with the Firefox Add-ons Store.

Recently, I suddenly encountered an "HTTP 406 Not Acceptable" error when trying to access the Firefox Add-ons Store. The store is completely unusable for me right now.

Here are the specific details:

Issue description: I have tried accessing the store on every network available to me, including mobile data, my office wired network, and my home wired network. Unfortunately, I get the same 406 error on all of them.

Timeline and context: Everything was working perfectly fine last week. I was able to search for and install a Markdown add-on without any issues. However, starting this week, it suddenly started returning the 406 error.

Additional troubleshooting:

I am not using a VPN or proxy. However, if I enable a proxy, the Add-ons Store works normally.

There is no antivirus software or firewall blocking Firefox's network requests.

Other websites load normally. Even mozilla.org works fine, but addons.mozilla.org does not.

I have also tried changing to other DNS resolvers, but that did not help.

Could you please help me understand why this is happening and how I can resolve it?

Thank you!

Hello fellow Thunderbirds,

I have been using Thunderbird for years and had thousands of emails in quite a few folders, with a shit-tonne of filters etc. My emails were running pretty well. I only use two addresses, but the folders help manage everything.

I just got a new computer last week. Prior to switching over to the new computer I read through the 'Export your Thunderbird Profile' help page, and the 'Move Thunderbird data to a new computer' pages. I've tried to follow all the info there (with a glitch, explained below).

I am using a Windows system and have gone from Win10 to Win11.

I have the following data:

  • Mozilla Maintenance Service (in Program Files (x86) ).
  • Mozilla Thunderbird (in Program Files (x86) )
  • Thunderbird (In Users/Username/AppData/Local/Thunderbird) (Contains 'profile' and 'updates'

I tried to swap the above data into the same spots on the new computer, but alas, it's not working. I *may*, however, have fucked it up myself...

So... When I got the new computer, I immediately downloaded Firefox, but, alas, I entered my email's details before closing it down. It did download a few off the server, but only a day's worth (before I realised I screwed up).

As soon as I realised I'd mucked up, I uninstalled Thunderbird and deleted the files on the new computer (you know how when you download it doesn't always remove all the stuff, so I tried to do this).

I reinstalled Thunderbird, but closed it prior to loading the email addresses on (as instructed). I then transferred all the above data into the corresponding file areas on the new computer. However, everytime I try to run the program it just goes to the standard open screen (with the popup that prompts you to enter your email addresses and details into it - see image, below, in case I'm not explaining it right).

Anyway, I'd appreciate any help you might be able to give me as I'm desperate to get my emails running again and have access to all the saved emails which were in my system. Kindly. Larysa.

I'm trying to remove a couple accounts that I no longer use in Thunderbird. A window keeps popping up asking for a password, but the mail service is no longer available. When I click on the red delete button for that account, nothing happens. I've deleted all the mail in one of them which I was able to do as I thought I might need to do that first, but I still can't delete it after that. The other one won't even let me delete the emails. How do I delete these so I stop getting asked to put in a password for accounts that are no longer valid and I don't want anymore?

I have the latest T-bird installed on a latest version linux Mint laptop and occasionally get puzzling errors on Yahoo mail.

Mostly it all works, but Yahoo email errors are often enough to be bothersome and I can't find any information on the rather obsure errors. Been this way through many t-bird and Linux releases.

My other email accounts don't seem to have a problem (gmail, outlook) on any t-bird instances. Just Yahoo mail on Linux Mint t-bird. Here are the errors:

"Please try later" and apparent timeouts on Yahoo mail (on t-bird, of course). This is obvious, but it doesn't happen on my Win 11 and Android T-bird programs.

Operation on yahoo "inbox" did not succeed. Yahoo mail server responded "p." (Yes, just "p.")

Operation on yahoo "inbox" did not succeed. Yahoo mail server responded "UID FETCH completed"

These errors don't seem to happen on Android t-bird or Win 11 t-bird on the same accounts, but I'm not on those for very long.

Any guidance would be appreciated.
