Zotero 2.1 makes firefox 4 to be freeze in extensions manager

I am using Firefox 4 in Linux Mint 10. I installed Zotero 2.1.1 (from the link provided); the extension works as promised.

However, it tends to "freeze" Firefox 4 whenever I open up the addons manager. I don't know whether it is a Firefox bug or something with Zotero but other extensions work fine. After removing Zotero, the addon's manager opened fine.

Could this be a bug? Can any one else replicate it? Can this be fixed? Thanks!
