Works just fine with FF5, just install 'Add-on Compatibility Reporter' add-on which allows installation of add-ons marked as being 'not available for Firefox X,x', (meant for testing purposes).
As for modus operandi, I don't mind having to right click short URLs to analyse them individually since I don't need to check every one on a page plus I think the CPU and network overhead is small because of this. Lastly, this tool is MUCH more efficient than others which stall at most of the links I've tried, this one gets 'em all!
Good work Love Sharma, you're a hero!
