I recently installed Firefox 4 after its release and updated the 1Password extension to support it. The extension works just fine when Firefox 4 is running in 64-bit mode, however sometimes I have to restart in 32-bit mode (like when watching Netflix streaming videos because Silverlight does not have a 64-bit version). When in 32-bit mode, the extension no longer works. Pressing the keyboard shortcut does nothing, clicking the "1P" toolbar icon does not bring up a menu, and right-clicking on the page, when you select the "1Password" option nothing is displayed. I've tried reinstalling the extension but this does not resolve the issue. Is this a bug? Is there something broken with my installation?
