Yes Ricky, it takes a little getting used to as it's not quite as IE-like as Firefox but once you're familiar, you'll probably never use IE again. Opera's fast and has some good features/tools and now our friend polonus has explained that I can use Dr Web there too I can see Firefox will get even less use. Of course, like all things, it's a matter of personal preference.
I've been using Opera since IE caused me real grief - nasty spyware - so much grief, the shop gave up on my PC and it was the experts here who helped me get it going again. I then switched from Norton to avast! (best move I ever made) from Zone Alarm to Kerio, and use IE only for MS updates. Since I started using Opera I have had NO spyware. NONE! I run all the scanners weekly, but there's nothing to find. Mind you, I'm a safe surfer and just don't go to "those places".
Thank you all for the links and info! Cool that there's always something new to learn!
Happy days to all
