  1. Mozilla has released Firefox 4. The final build comes less than two weeks after Release Candidate 1. The company originally found no major problems in the RC1 build, and decided to release RC1 as the final version, but then changed its mind. An RC2 build was quietly pushed out on March 18, 2011 with a few fixes, and today the final bits appeared on Mozilla's servers.

    If you have a previous build of Firefox 4 and navigate to the Help>About page, it will automatically download the update and bring the software up to the release version.
     
  3. If you want to save tabs when closing firefox.

    browser.showQuitWarning - set it to True

    I wish there was a Like button for this.
     
  5. Is there a way to make sure all your add ons are compatible before you upgrade? I usually hold off for a month or so to give them time but if I knew for sure I would upgrade now.

    when you close firefox 4 the tabs are saved.
    you have a button on the homepage which will restore them when you open FF again.

    About the addons - go to and manually check if the addon supports FF4. if not then check if a beta version of the addon is available. (example: FEBE, firebug - beta stage but work just fine). if you find nothing then just force FF to install it. many addons still work even if there is no new version for FF4

  11. You can get your tabs by clicking on history, then restore previous session.

    It was RC2 but when you look at the "About Firefox" it just said 4.0 . maybe because they were preparing for 4.0 but they were forced to push a second RC and they didn't have time to change that (or just forgot about it)

    I abandoned Firefox in the early 3.x days because it seemed to get slower and heavier with each release. This version... I actually like. Now my browser hierarchy goes Chrome>Firefox4.x>IE9>Opera>IE8>IE7>Firefox3.x>Safari

    Is there actually a point there somewhere? It seems like you might waste more time deciding which browser to launch, than any possible speed gains you might achieve by your decision.

    Captaincranky says, "Chrome is only good for motorcycle parts, just say "no" to it as a web browser"! :haha:

    Hey Cap !
    Luckily my choices are rather limited to two options only i.e. IE9 & FF4. So I don't have to go through all the list LNC have; save lots of time I bet. ;)

    I'm sorry, but did you really put IE7, and IE8 before Firefox 3.x? Hahaha, GTFO.

    Yeah, I did. As I stated I really disliked the FF3.x releases. I much preferred IE 7 and 8 over FF.

    It's Fx anyway.
    I don't know why anyone would use IE. Their zone security is a joke. The only good thing is you get to see what cookies a website is setting and maybe for corporations it's easier to manage (restrict access).
