Help! Safari suddenly opened hundreds of old tabs!
I'm running Safari 7.0.3 on my MBP in clamshell mode with a Thunderbolt Display. While using the Royal Mail website (in the UK) I suddenly started getting messages about unable to do this or that, then realised that the machine had opened hundreds of tabs, some very old from years ago (hence the error messages). I can't see how many have opened because the list goes off the bottom of the screen when I hold down the arrows.
I tried re-booting Safari, then re- booting the MBP but to no avail. The fans are naturally working flat our and my CPU is working at about 99%!
Is this a virus? What do I do? My tech support son is on a long-haul flight and I'm panicking ....
Any ideas anyone?
