As of firefox update 44.0, I cannot get firefox to work properly. Trying to connect to any website gets stuck at "Connecting." I have no add-ons, extensions, or themes installed, and I tried all of the suggested troubleshooting with hardware acceleration etc. The only time firefox will run is in safe mode, or immediately after I "refresh" firefox completely. As soon as I close and re-open it after a refresh, it stops working again. I have tried updating and disabling all plug-ins as well. This likely goes without saying but internet connection is fine otherwise. Thank you for any help! (i don't know if the troublshooting info will be helpful, this is the information from immediately post refresh while I can still connect,)
