@Stanisable Ok, it is broken only when ProtonPass extension is set. Nothing surprising here, @protonmail is having a really good time nowadays breaking everything that once worked on each update.
@christophe@Stanisable Hi! We'll fix the issue in the next update of the extension. For the time being, please downgrade to 1.14.1 by reinstalling the browser extension and this should resolve the problem.
The patch with the fix has been submitted and we're waiting on Firefox to approve it.
