I have Firefox on a couple of (Windows 10) PCs. This problem is happening on one of them. It has two profiles (users), and it's happening on both. If I open Firefox, and then trying going to google.co.uk, or do any google related search, almost everytime there is an obvious 30-40s delay. Indeed, during this time I can even open up other web sites (immediate), and trying google.co.uk again, and delay continues to occur. Opening up the Network Console in Firefox, the GET request can be seem and then like clockwork there is about a 41000ms delay until it then continues. If I open in TroubleShoot mode, same issue. If I open in a Private Window, the problem does NOT occur. This problem does NOT happen on my other PCs with Firefox, or any other browser on the PC in question. This is very frustrating :( You open firefox to do a google search and it takes tens of seconds to resolve (on the first attempt) :(
