    I've had nothing but problems with Firefox 39.0 (using on my MacBook Pro OS X 10.6.8). In order to quit, I have to force quit. It freezes up continually. I'm about to uninstall it and start using a different browser. I'd give it a 0 stars if I could.

    Here's the first review in 3 years.
    This version is smooth and fast performing, literally taking many of it's looks and ideas directly from Google Chrome.
    Along with smooth performance comes better memory management.
    Firefox is probably the most configurable browser as well.

    Seems to work great with Mountain Lion 10.8.1 and updating Firefox from ver 14.

    Appears to have flawless integration.

    Reviewing 4.0 Beta 3 (Aug 11, 2010)

    Doesn't work on Tiger (MacOS X 10.4.x for the non-cognoscenti...), hence the low rating. It's a shame really: Mozilla is following in Google's footsteps when it comes to Apple OSes, and forgets that not all Mac users can or want to switch to Snow Leopard. Might as well spit in our eye... Take Opera as the (perfect) counter-example, they who have recently launched a new version of their browser that's really multi-platform. Shame on you, Gorgonzilla! (pardon the cheesy pun...)
