I love FF, it don't know what I would do w/o FireNICO. I have Safari, Chrome and IE8 installed also but I never use them. I don't like how you have to build Chrome to fit your needs and Safari is just too hard to get used to. I haven't even used IE8 yet as it came installed on my laptop b/c I have Vista Premium 64bit. Firefox has so many add-ons and plug-ins that you can literally spend days sifting through them all.
If you install Down Them All you'll never have to worry about losing anything that you save to your computer, If you get My Xmarks you can transfer all of your bookmarks in one easy step and it remembers new bookmarks and will transfer them when you use IE again. Plus with the bookmarks in FIrefox you can customize them and give them tags so they are easier to find and most will have a little symbol next to them to make them even easier to fiind.
I used to have a problem with FF crashing my desktop as there is a corrupt file that if you use any MS product you have to reinstall FF every single time, but my desktop is old, running XP, and severely needs to be reformatted. I haven't had any issues on my laptop. As far as crashes go I've only had a couple crashes happen and they were caused to either too many tabs being open or some sites just aren't FF compatible.
Oh and the Private browsing and easier cache/history clean up make it a win for when you don't want to gf or wife knowing that you're looking @ Pron. As far as the Ad- Block goes, I think mine is broken b/c I get ads like crazy.
Bean if you go to the help tab at the top there is a link for IE users that willl take you to this page,
