Tabs panel missing

One of my add-ons replaces the tabs with a modified panel. Due to a recent issue (https://support.mozilla.org/en-US/questions/1257967), all my add-ons are disabled, but the original tab panel doesn't come back. Switching tabs with ctrl+tab key still works.

I suppose when the recent issue is resolved, the add-on will come back and the problem will disappear. However, it seems to indicate that firefox is not disabling add-ons properly, i.e. disabling them does not recover to a previous state.

Btw, I'm using firefox 66.0.3 on Ubuntu 18.04.

There is a problem with an expired intermediate certificate that is used to sign extensions. This is being worked on by the Add-ons team.

See:

At about 6:10 PST we received a report that a certificate issue for Firefox is causing add-ons to stop working and add-on installs to fail.
Our team is actively working on a fix. We will update as soon as we have more information.

did you apply a userChrome.css hack to hide the normal tab UI? (webextensions wouldn't be able to do that any longer)
