The update to opera 25 seems to have fixed the slow mac pop ups. Hopefully it will stay that way. Thanks avi.
I didn't know there was a update to 25, it always said opera was up to date.... hmmmmmm.
chas4, flash is the overall problem. Its sucks on all my web browsers, and not just on the macs. Adobe has had plenty of time to fix the issues and they seem to do nothing about it. I wish more websites would phase flash out, as there are much better options out there already.
