I’ve just installed Comodo (5.10.228257.2253) and I have a problem with Facebook. All websites I tried are loading properly except this one. It’s loading very slow, Chat is not working and I can’t load older posts. Moreover notifications bar on the top is not working too. I’m using Opera, but the same problem is in Firefox and Dragon.
Not a Facebook user here. Could you first try to clean cache and cookies of your browsers and restarting them? At first sight it looks more like a browser issue than a firewall issue.
Thank you for your reply. Cleaning cookies and cache didn’t help. But now, after few reboots it’s working again.
It may have been a problem with Facebook altogether. Glad it got fixed.
