Thunderbird incoming attachment opening issues

Hi,

I recently received a PDF attachment from my customer but Thunderbird was not able to open it.

I had set Microsoft Edge to open PDF by default. I got this error message.

File not foundIt may have been moved, edited, or deleted. ERR_FILE_NOT_FOUND

Whereas, if I saved the file to another location and I try to open it (again with MS Edge), there is no problem.

It seems having an "#" in the file name was part of the reason.

I could set Firefox to open the PDF by default but there seems to be disappearing fonts (in some instances) when I open a PDF with Firefox.

Not sure what to make of this but I am posting this here in case someone finds it useful.
