I've had this problem for a long long time. Even before the Curse website was overhauled and updated. I can't seem to delete favorites. I tried it using IE7 and IE8, FireFox, and even Chrome. I've seen a few others with this problem in the forums, but never any solutions.

Has anyone had this problem and found a fix for it? Any help would be much appreciated.

Thanks for the report.  We're in the process of changing the favorites system to bring back email and visual change notification, and I'll make sure this issue gets resolved when the new system is deployed.

You may try going to the addon page and clicking the 'Remove from faves' button in the meanwhile.

oK, thanks for the response. I did however find that if I F5 to refresh just before checking addons and pushing delete selected, that it works. Although it goes to a page that says an error in big bold lettering. I refresh again there, then use the back button it finally goes through and deletes the unwanted favs.
