I noticed my firefox 4.01 crashes every time when "leave extensions unlocked when browsers are closed" is enabled.
IE 9 doesn't crash. I reinstalled the 1P plugin but FF still crashes every time I hit the 1P button. When I disable "leave extensions ....." everything returns back to normal.
1password version 22.214.171.124. I have 2 more plugins installed, ad muncher and symantec.
