I used to use Firefox for everything. But recently some work-related websites have been created that work best on Google Chrome, and now that I have downloaded it, I LOVE it. It's so much faster. I have no idea why that would be, but it is!
Been using FF for years but it's been pissing me off lately. Thinking about switching to Chrome in the future, but I don't know that it has all the add-ons that I'm used to in FF. That's been the biggest deterrent.
But if it uses a fraction of the memory that FF does...it's ridiculous that a browser can't stay open for more than a few days without engulfing 900 megs of memory.
