Firefox better? Certainly not for everyone. Seriously do you think that 5% of web users are morons or something? Firefox ad ons are mostly crapware. Safari's RSS reader is infinitely better. Interface and commands are more mac-like (obviously) which means less commands to remember. It is faster in most installations I've seen. For that 5% it's obviously a good choice for them.
I don't care about the majority of the 'toys' that get passed off as addons. The only two addons I *cannot* live without (ignoring all the development ones) are:
- Adblock - which gives me back my browser from those damn marketing Muppets who design moving adverts
- Mouse Gestures - click on a link, find I want to go back, so click-wipe to left and back I go. No hunting for the back button or pressing backspace.
For development there's a ton of addons which makes Firefox THE BEST BROWSER FOR WEB DEVELOPMENT BAR NONE.
- Web Developer Toolbar - where would we be without it?
- Tamper Data - examine headers and change postback parameters
- FireBug - for debugging JavaScript and so much more
- ColorZilla - simple colour dropper to determine the colour of something under the cursor
- MeasureIt - a simple measuring tool for widths and heights
- HTML Tidy - check your code for bugs
I could go on. Honestly, anyone who does serious web development cannot not afford to not use Firefox.
