#47 Breaks Firefox 2.0.0.4

[Anonymous]

Tab Effect worked for a while, but then stopped working, popping up an exception error ("Exception: TypeError: url.indexOf is not a function") when changing tabs (without the tab effect ever showing)
I tried disabling and re-enabling without results.
I tried uninstalling and reinstalling without results.
At that point, I just uninstalled it permanently, but the Exception error keeps happening on occasion when I switch tabs. I've tried uninstalling and reinstalling Firefox, but it didn't fix the problem.

How do I fix this? It's a major drain on system resources when I have multiple applications running.

Tab Effect also crashes 2.0.0.4 when I press ctrl+shift+tab to go the previous tab.
