I am on Linux Mint 22.1 Xia - Cinnamon - all updated - for a second I thought maybe Kernel problem, but only on new messages? Na Just updated kernel - no change - obviously.

Thunderbird is the Flatpak version - I prefer it contained in Flatpak

What is weirder, I have not done anything to it or the whole Linux system!

I even was away for almost 2 weeks, I barely use it at present as browsing and emails. Sometime testing hardware.

Thanks

Note: I am no Linux guru - please be simple - thanks

I have taken Flatpak version off and used the System one (the +Zara) and imported data.

Same

I also noticed - although email works fine, it does not connect its Browser?

IS there a About:config setup to chose which browser.

I am just guessing it wants to use Chrome that does not exist in any of my computers?

Thanks M

PS the end of Thunderbird ? mmm On mobile I do not use it, used k-9mail then you know what and I use alternative one now...

I switched to Betterbird and works fine.

The only problem I have is that I cannot drag and drop emails from a folder to an inbox and vice-versa.

I used to do it...

Let us know if you find out the exact cause of the problem
