Firefox has been suffering from feature creep for years, causing it to become as slow and bloated as IE.
I recommend trying Chrome. It performers much faster and is more stable.
Of course there is that whole Google thing. Do you trust a product made by Google? If you can get over that issue, it’s worth a try.
Thanks. Running Chrome on daughters laptop, had it on wife’s laptop for a while. This computer is just getting old, I fear.
