Extension Addon list not visible

[Ed Dunlop]

running current Natty (updated yesterday). When Firefox 5.0 starts, some extensions error out, others start. Going to "Tools | Add-ons" shows an empty list of extensions so it is impossible to disable or remove them.

Unfortunately, the error console is overflowing with errors from logging onto Launchpad.

This error repeats with each restart. I can do a "Help | Restart with Add-ons Disabled" and FF comes up without most extensions but still no list of extensions in the add-on list so no way to control or remove extensions.

I have copied the first messages from the "Error Console" as Firefox starts:

I got the Add-on section working again by re-adding one of my current extensions into Firefox again. This made all of the extensions reappear in the Add-ons list. I now have control of the extensions & Appearance items and they all appear to work, but I am still getting numerous errors in the "Error Console".

Ed,

We are sorry that we do not always have the capacity to review all reported bugs in a timely manner. You reported this bug some time ago and there have been many changes in Ubuntu since that time.

Presumably this problem was a one time occurrence and/or is no longer an issue? Can this bug report now be closed?

If we do not hear from you the bug report will close itself in approximately 60 days time.

Thank you for helping make Ubuntu better.
