    Reviewing 51.0.1 (Jan 29, 2017)

    I've been using Firefox for many years, first in Windows XP and then in Debian. At some point betas as well as normal releases became too unstable for me to use so I started using ESR versions. Now even ESR versions seem like betas. Something is just not right with Firefox any more. It lags in about everything you do with it, but I'm so dependent on it. Sad. It must be overbloated with trashy code, I don't see any other reason why it is so laggy. And in the mean time I changed three PCs in the last 10 years. The one I have now is far more powerful than the first one. Mozilla, please hire some better coders and/or make a new browser from the ground up. This is going nowhere and I'm considering using alternatives. You've lost so many users in the last 10 years and it is perfectly understandable why. It' a shame though because we do need an open source browser. Good luck! Can't give you more than 3 stars and that is for the effort. Your programmers suck big time.

    Use the PPA for Ubuntu if you want to get the latest stable version in your updates.

    Open Ubuntu Software Center>> Edit>> Software Sources...

    Click Other Software tab and click Add.

    Then just paste:


    Click close. Open your Update Manager and you can upgrade from 3.6 to version 4.0. Sweet!!

    If you are 64bit Linux this link will give you a 32 bit version which will run, but none of your plugins will work. For a 64 bit version, check here;

    Incidentally I'm on FF4 on Ubuntu64 and its literally 60% faster than FF3.6, really really amazing improvement.
