Firefox Snap unable to save html files

Hello,

I am unable to download html files with Firefox snap (Save Page As), it tries to download then in the download progress it just says “Failed”. Other filetypes can be saved just fine, and the Firefox .deb version works just fine with saving html files. I believe this has been a long standing issue for me but I never ended up reporting it until just now.

Here are my system specs:

Does anyone have any ideas what might be causing this? If you need any other details please let me know.

I can reliably observe the problem here.
I installed the latest stable firefox snap in a fully up-to-date 18.04 VM, and when I browse to about:buildconfig and right-click on the page and choose to “Save as…”, the download fails just as you described. If I then open the downloads popover from the toolbar and click the “refresh” icon next to the failed download, it works.

I cannot see any relevant denials in the journal.

Can you file an upstream bug with these details (please make it clear that it’s affecting the snap package)?

I am experiencing issues with both “Save Page As”, “Save Image As” and “Save Link As”.
On Firefox 84.0.2 (64-bit) snap on GNOME v3.38.2 with Debian Buster or Bullseye.
