I've been loath to update to Firefox Quantum, as the selection of addons I use makes for a very fast and productive work session when using FF 56. The past couple of weeks my Firefix 56 has begun getting stuck either "waiting for" websites or getting stuck on "transferring data from... [site x]". This is made extra worrying by the fact that it does the same thing even when I'm connecting to my router which is connected to my PC by a 2m network cable! Sometimes it takes the router's landing page up to 3 minutes to load, when it used to be instant. I tried creating a new profile, but it does exactly the same thing. I tried a couple of other browsers like Waterfox and Basilisk, however they lack important features like proper support for Internet Download Manager and QuickDrag/Superdrag doesn't work properly. If anyone can suggest some fixes I might try, that would be great. I've done the obvious like clearing the cache, updating graphics drivers etc. but none of that has helped. Thanks!
