It seems to be slower downloading images and leaves some blank. Although I do live across the Atlantic. So I upped my iMac from 4GB of RAM to 16GB. I use it in our nighttime here so there seems to be the odd problem, but most of the time at 03:30 am it is OK. It is not very good during the peak periods and I have fast broadband.
Plus Firefox keeps cutting out and says try again for security reasons. You can get the post back you are writing, but it does take its time.
Time for a wee dram, and wait.
Regards.
Neil.
