Won't load more than four tabs at once following latest update
I've searched forums and tried reloading with add-ons disabled, tried reinstalling, but nothing helps. Once I have four tabs open, it won't load more. The tab shows my destination address in the address bar, but just spools and won;t load. No error message. I suspect it's something to do with the latest update (I think installed last week?), but am not sure.

Boot the computer in Windows Safe mode with network support to see if that has effect in case security software is causing problems.
