thunderbird will not allow attachments of any kind or size

Seems like the same issue as on Windows: https://support.mozilla.org/en-US/questions/1609202

Same problem here. The problem has occurred with the latest update to Thunderbird. For reference, I am running Linux Debian KDE Plasma 5.27.5. Thunderbird version 1:140.17.0esr-1 deb1 2u1.

Thanks

I suspected that. I will also contact support for my OS and see if I can attack it from there.

I am running 153.4.0esr Wed

Any way too report this to Mozilla other than here? It's really affecting my workflow. Thanks

I had some what the same issue https://support.mozilla.org/en-US/questions/1608942 I fixed it my way but I hope mozilla can fix the cause

something a wish I knew when I had the issue was if you needed to send a image another way to do it then attach is menu bar insert > image

I think I have found the issue. It is likely not a Mozilla problem, but is the result of a recent OS update.

I tried attaching and sending a message from another
computer here that is running Linux Mint. No issues. Everything works.

On my main system, running Pop_Os, I am not able to attach a file to a Thunderbird message at all. Neither of the buttons work. If I try dragging a file into the message, I get only a link to the file which does not work. Just before sending, I get the error message asking did you forget the file?

Any other tests you can suggest to confirm my suspicion.

And THANK YOU all for your assistance!
