I am not sure when it started, but Facebook was handing too often in any browser in both my desktop and laptop.
I was unable to upload pictures, navigate through people's timelines, check updates and post.
Nothing that I tried worked, such as cleaning cookies, verifying and disabling browser extensions and add ins and shockwave flash version check, etc...
Then I stumbled on a thread that suggested to turn Stateful Protocol Filter option off in the general settings of the Norton 360 Firewall.
Disabling that option made FB work as expected on every device I have Norton 360.
But I presume that is not the best approach, I feel like I am unprotected at a certain level.
Are the plans to update the filter to make it "compatible" with FB?
