Ever since an upgrade a few days ago this Home Improvement site has been running super crappy in FF - all other browsers it is fine. The site locks up constantly and takes 10-15 seconds to load sometimes. I am behind a proxy server most of the time so it could be something that is loading through our firewalls quickly, but I don't have any issues with other SE sites and like I said other browsers work fine - checked in IE11, Chrome, Safari. Anyone else having problems?
I am not really seeing much go on during the hang state. Right before the hang state I get a console error "The connection to wss://qa.sockets.stackexchange.com was interrupted...". It then handles trying to load all of the extensions. It hangs every time I visit DIY or DIY meta and no other SE sites. It also hangs every time so not intermittent at all.
Update: Site is basically unusable in FF (W7 64). In IE11 it is definitely loading slower than other SE sites but not a huge deal (.5-1 second vs instant).
Also another weird behavior was noticed today. I haven't used site as much lately because of the issues. But brought it up in IE11 today. Logged in. Answered a few questions... Saw that I had an answer with a comment on another SE site. Clicked on the other SE site to open in new tab. Took me to the answer and I am not logged into the site and I didn't see the common "refresh" login bar that I would normally see. First time this has ever happened. I suspect that part of the core SE was not uploaded correctly during the last update.
Another update: As of today FF is responding much better. Not "fixed" but much much better. Instead of hanging 10-15 seconds on every load it now hangs 1-2 seconds. I am assuming something was changed over the past couple days. But there is still a load issue.
