Summary0006625: give better errors when web extension backend doesn't respond
DescriptionDue to various browser issues, it is possible that the web extension background page doesn't respond properly to our messages.

Instead of just being "stuck", all the wallet UI pages should try to display better error messages.

Ideally we'd link to some FAQ with instructions on what to try/do about it.
TagsNo tags attached.

Florian asked me to provide the inspection output for the Taler Extension. Hopefully the "Console" output is the needed information:

I forgot to add my screenshots.

db.png shows original settings before I switched all values to "true". But that didn't help. (even after re-starting Firefox.)

loading.png shows what I get after I try to withdraw KUDOS into my browser wallet. (This screen stays forever.)

Thanks, these are exactly the logs I was looking for. From the logs, it's not really clear what's going wrong, other than "the WebExtension UI is unable to talk to the WebExtension background page".

Just to confirm, is this using the latest version of the wallet from the Mozilla Addon store? (Should show up as "0.8.0.2" under about:addons)

I wasn't able to reproduce this myself with 78.3.0esr. We had a similar problem in the past, where the extension simple wouldn't work on certain profiles.

Would it be possible for you to try the Taler wallet under a fresh Firefox profile? You can either start Firefox as "firefox --new-instance --ProfileManager" or go to about:profiles to run it in a new profile.

Once we know if this is an issue with certain profiles / configurations, we can figure out what's going on from there.

Yes 0.8.0.2 is the Version number I get if I open the details view in the Add-on Manager.

The Taler extension instantly worked in the new profile where this was the only extension without any personalisation of the browser.

My original profile might be rather unusual. I always use private browsing, delete all data when closing the browser, I use Adblocker Ultimate and have the Gnome Extensions manager installed. Aside from that I have made several adjustments for more privacy (but I didn't need to go into the "about:config" page for that. So it shouldn't be way out of the ordinary.)
