firefox problem to restore session, scrollbar left instead right, links cannot be executed

[brkas]

Binary package hint: firefox-3.5

Ubuntu 9.10
can't find out what package I am using... Synaptic 0.62.5 ?

Firefox has problems to restore closed sessions. It was either displaying information that add-on Collorzilla is now installed or Nitro PDF (although these were already installed).
Pressing on links it has problems to execute these.
Scrollbar which is normally on the right hand side is sometimes suddenly on the left hand side.
First error message was with All in one sidebar. Outward apperance is slightly changed.

Followup: After deinstalling most of the add-ons links are now again executable and everything seems to be back to normal. Because it were quite some add-ons I couldn't say which deinstallation finally fixed the problem. Maybe in the other technical information which are automatically generated?

https://support.mozilla.com/en-US/forum/1/515668 seems to be the same problem, and points the finger at the SwitchProxy Tool Add-on.
