[Users] Firefox, Chromium won't open HTML mail

[Pierre A.]

Hello,

I observed this just a few days ago (possibly after an automatic Firefox update) :  HTML mail cannot be viewed in Firefox 93.0 by clicking the image icon in Claws mail, because

Firefox won´t open this kind of URL 
file:///home/alba/.claws-mail/mimetmp/*.mimetmp.html

where * stands for a variable digit sequence.

Firefox gives the error message 
"
Access to the file was denied

The file at /home/alba/.claws-mail/mimetmp/*.mimetmp.html is not readable.

    It may have been removed, moved, or file permissions may be preventing access.
"

Actually it is not a problem of permission but file name.  Firefox does not like the termination ".mimetmp.html".  Removing ".mimetmp" solves the problem.

Same thing with Chromium 95.0.4638.54.

However, no problem with Dillo version 3.0.5 and Google Chrome 90.0.4430.93.

In conclusion, I think it might be useful to modify the file naming scheme in Claws mail in order to make it compatible with Firefox and Chrome.
