I find that with my Mac, on Safari, the problem happens only intermittently. So I have no way of knowing what causes it. Whatever the reason, it is terribly annoying.

I see an invite to Google chrome, but am afraid to click on it. I am a very timid, computer-clue-less fraidy cat who fears messing with anything I don't know anything about. If there were a way go click on something and be able to back out without affecting anything, I might be a bit more daring. My son, the computer guru in my family, is exasperated with me so I don't often venture into the realms of my ignorance. I know how to turn the key to drive the car, but have no idea what makes it run.
Sorry this has turned into a rant. I guess I am more exasperated than even my son!

milkmaid42 you are NOT alone! I am very much the same way except I have a laptop that right now is not usable because I clicked on something w/o reading it completely and now NO icons will come on screne and no way to connect to the internet.......thus I'm on a public computer 
Kakeladi, I'm so sorry for your predicament! But you make me feel a little better for my caution. I usually feel like an idiot at the keyboard and I'm so glad that I haven't screwed up yet. But there are a lot of features I miss out on, I'm sure. Is there any hope for your resolving your trouble? I sure do wish you well and hope you get things fixed. I guess a few ads and some annoyance are tolerable.
Leah, I don't have Firefox. Just a Mac with Safari and I use iGoogle. I'm used to it, providing nothing changes. I fear I don't do well with change or new things.

Hmph! Pick a number...
