Dear Team. As always thanks for a great browser... I had a Firefox update come through this morning (through the browser prompt). After installing the update the pc became extremely sluggish. Thought it may need a restart so restarted the pc but pretty much the same issue? Slow, delayed and sluggish. I checked what was running in the back ground and other than the usual microsoft nonsense and background stuff it showed 30 instances of Firefox running taking up 82% of the memory. I always have one browser with 8 tabs running by default. I'm running an i7 processor with 8gig of ram which should be more than ample. Any thoughts / ideas would be most welcome. Once again, thanks for the best browser.... Best regards, Kev Brown. Brocott UK
