This workaround is now obsolete.

Please use the the official method to get rid of this issue...

Just open a new tab and go to about:config and filter on signatures.required and double click both of them to turn them from true to false:

Nasty Red

and the nasty red turns into a fine yellow:

Nice Yellow

Which allows me to move on for the moment, until:

    It would be even better if you add the link to the bugreport - https://bugzilla.mozilla.org/show_bug.cgi?id=1548973 and Mozilla's twitter https://twitter.com/firefox/status/1124527050490933248 . To show that Mozilla knows about the problem and working hard with fixing it. – N0rbert May 04 '19 at 10:32
  • I do not know if it will work for long. Firefox is disabling extensions it does not approve and/or that have obfuscated code. – Rui F Ribeiro May 04 '19 at 10:45
  • @DKBose I agree, that is why I said "it will not work for long"...but alas, it might not work for long, if we are pedantic today. – Rui F Ribeiro May 04 '19 at 10:59

    A [partial fix](https://bugzilla.mozilla.org/show_bug.cgi?id=1548973#c57) is being pushed out via the [Normandy](https://wiki.mozilla.org/Firefox/Normandy/PreferenceRollout) route. – DK Bose May 04 '19 at 11:06

    Note that to receive the fix via *Normandy* you must enable *Firefox studies* under *Privacy & Security*. – DK Bose May 04 '19 at 11:28

    Will there be a regular fix as well, one in the form of an Ubuntu package update? When? – Wolfgang Jeltsch May 05 '19 at 20:32

    Any update on when this will be fixed in Ubuntu? – Tor Klingberg May 07 '19 at 09:05
  • **IMHO:** Disabling security is neither *recommended*, nor a viable *long term solution*. Allowing 'Studies' (discussed below) also require diagnostics (data sent to Mozilla) to be enabled (although this is already **enabled** by default). Use this 'solution' until **66.0.4** (with actual fix, and replacement Add-Ons certificate) is released (via normal update process) to Ubuntu. – david6 May 08 '19 at 07:18
  • @david6 See comment below other answer: once released to the Ubuntu repositories, I'll be changing the acceptance of the answer. **0:-)** *For the moment,* this is the best solution yet... **;-)** – Fabby May 08 '19 at 07:28

Firefox 66.0.5 has now been released by Mozilla which avoids the Master Password issue in 66.0.4 which prevented the previous fix from working in some cases.

After the update arrives in the Ubuntu repositories, anyone who has used the workaround and disabled extension signing in about:config should re-enable it by double-clicking on the:

  • xpinstall.signatures.required and
  • extenstions.langpacks.signatures.required

settings again to set them back to the default value of true.

More Mozilla support information here.

Obsolete now:

Firefox 66.0.4 has been released by Mozilla which should fix this without requiring the Studies functionality and is now in the package repositories for all supported branches of Ubuntu.

  • @Fabby: 66.0.4 is now in the package repositories for all supported branches of Ubuntu. 66.0.5 will presumably also appear soon as it is already showing in Eoan (but 66.0.4 should fix the issue for the majority of users). – djcater May 08 '19 at 21:54
