    Which one uses less processing power and allows for more battery life overall?

    Also are there any other benifits to one over the other?

    I don't think choosing one browser over another will have much of an effect on battery life. Just choose the browser that you prefer, since they both conform well to web standards and both have good compatibility with most websites, with FireFox having a slight edge from my experience. I personally use Safari on my MacBook Pro and switch to FireFox for the occasional website that does not work with Safari.

    On my MacBook safari uses much more processing power that firefox! This happens not just when it's being used, but also when the window is closed it seems to eat CPU cycles and makes my fans spin up. Obviously this has an affect on my battery life. Firefox on the other does not use as many resources.

    I like safari but it just doesn't work right for me

    Yes... when you open an app but you don't quit the app, it will still use CPU cycles. Firefox will do the same thing.

    You can customize Firefox to do pretty much anything you want. Safari... not really.

    I really like the features in Firefox, but for me firefox uses 4-5 times more memory than Safari.

    So nowadays i use Safari for day to day use, although I miss the addblocker from Firefox!

    these CPU cycles are so small they will hardly change the overall battery life.. you may get 5minutes less battery life (if that).

    if you were to leave a window open (such as a MacRumors page) the flash applets on it might reduce your battery life quite significantly. make sure you close all windows you arent using if you want to preserve battery life.

    ... I know that. But the poster I replied to doesn't, so no use telling me! :rolleyes:

    I think Firefox is better if you want to fiddle around with themes, plug-ins, etc. Safari is definitely superior in terms of performance, javascript, and speed.

    I haven't noticed any difference in CPU usage, but I deffinately have noticed it in ram. Safari uses more memory then Firefox, atleast on my MacBook.

    what performance? why easier to use is not counted as performance?
    what javascript? why supporting of more recent version of EMCA script isn't counted?
    what speed? why faster to reach sites users want isn't counted?

    you just have a javascript speed test and you put a lot of statements on that. Its misleading at least.
