None of my add ons are showing. Firefox 18.0.2, Ubuntu 12.10. Recent issue.

All sympthoms are similar to question at

The version 18.0.1 was fine, no any problems. Problems have started since I updated Firefox to version 18.0.2, before it was no issues with extension compatibility. Everything works except add-ons. I cannot install and/or update add-ons as well. I cannot open the page at The page gives a message: "The connection has timed out".

Add-ons bar at the bottom of the screen seems to be working, but none of my extensions are showing next to the navigation bar. I run Firefox on the Linux Ubuntu 12.10 (32-bit), as well, and no issues.
