Comment 62 for bug 281348

I'm also affected by this bug in Karmic AMD64. Steps to reproduce:

- create new FF profile
- install e.g. Adblock Plus which will put an icon in your toolbar and restart FF
- at this point, the ABP icon is still being displayed
- install Tab Mix Plus and restart FF
- at this point, the ABP icon is gone
- disable either TMP or ubufox and restart FF
- at this point, ABP icon is displayed again

Adblock Plus 1.1.2
Tab Mix Plus 0.3.8.2
