Comodo Dragon and Facebook

I have been using Comodo Dragon for a rather long time now and never had any problem with it when being on Facebook! But after the latest update to it acts very strange, i cant open my mailbox nor can i see Youtube videos posted at Facebook! Guess i have to use another browser then!! But i do like Comodo Dragon!

Edit: Nor can i delete old posts!

Delete old posts from where? I know I have problems deleting history. I have to choose edit and manually delete them.
