moderation comment: endless page loading

Hi everybody!
I need some help with comment moderation... I’m going crazy!

Let me explain:
I have MODx Evolution 1.0.5 with Jot 1.1.4, pages are not cached, I have FriendlyURLs and my Jot call, included in {{comment}} chunk, is:



It seems to work fine but when I try to edit or delete a comment, the page begins to reload and doesn’t stop untill I clear Firefox cache and cookies and I reload the page (obviously no changes are made).
If I don’t clear Firefox cache&cookies I can’t visit any page of site, it seems busy doing something...but what?

Please help me, I can’t understand what is the problem and I’m thinking about dropping MODx, but it would be a sad solution because I love MODx!!

Thanks
Giulia

Hi,
I think that this issue depends on the browser (Firefox 4) so I try to edit a comment with Safari 5.0.5 and everything works fine.
Do you think I should reinstall the previous version of Firefox?

Thanks
