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.
