    That is a fantastic fix!! Glad you posted this. What I can’t understand is why these settings are not the defaults. Firefox on Windows does not have this problem. Seems like this needs to be changed in the Linux version.

    Fresh install of 10.10, Firefox is fast again! I can’t believe the defaults make it so slow! THANK YOU!!!

    Strugglin’ for months with this problem and it seemed to get slower from day to day. Till yesterday, when webbrowsing was totaly shutdown.

    Wasn’t able to identify the problem. Thought it was a networking problem in the wifi or something.

    Keep publishing fixes. Damn importend.

    Thank You!

    Man, you are a godsend! I can now download my podcasts in style. Works great on 9.10.


  18. Matt says:

    Thanks, works great on 10.10

  19. Tarrasch says:

    This DOES work!

    For a while I thought:

    Firefox – find link in 1 sec, load page in 5 min
    Chrome – load page in 1 sec, find link in 5 min

    With this fix firefox has become the best again! Don’t switch to chrome (for speed reasons) before you’ve tried this!!!

    Amazing! Ubuntu browsing is alive on the WWW again! Ive been painfully suffering since moving to 10.04…

    Any similar fix for increasing download speeds using browser applications like DownLoaderHelper?

  21. Nicolai says:

    Great fix! Works here too!

    What does the http pipelining do though and why does turning it on fix the problem?
