If you are already not convinced that firefox is better than everything out there, here are a few tips and tweaks that will make you want to switch. If you are using firefox, maybe you still didn't know about these.
Step 1: Getting Firefox
Just download and install firefox... Works with just about every operating system there is... But don't get the beta, there aren't as many themes and plugins for thosehttp://www.mozilla.com/en-US/firefox/
Step 2: Speed 'er Up!
Do this if you have high speed internet, it won't work as well if you are using dial-up.
In the address bar, type in about:config
Once you are there, in the filter bar, type in pipe. You will come out with 3 results, network.http.pipelining
The first and the third should normally be set to false, and the middle one should say 2.
Double click the first and last one to set them to true, and double click the middle one to set it to 20 or 30. Try each out or even different numbers and post your results, because i did not really notice a different between 20 and 30, but then again I have satellite internet.
That 20 means it will make 20 requests at once, now you know why this is only for people with fast internet.
Step 3: Still Movin' Fast!
Now, right-click anywhere in the window, select new, then select integer. Name it nglayout.initialpaint.delay and set the value to 0. This is the delay to open a web page.
Step 4: MORE MEMORY
Now, to give firefox more memory, make a new integer, name it browser.cache.memory.capacity and depending on how much memory you have, give it anywhere above 8 megabytes. To do that, set the integer anywhere above 8,192. It's in kilobytes... I have mine set to 90,000 which is i guess around 90 megabytes...
Firefox seemed to respond faster after doing this...
