Firefox 4 slow? Make Firefox 4 faster

Make firefox faster
Firefox 4, the latest version of Mozilla Firefox, was too slow for me. The browser looked good in design, so I upgraded it(regreted it), but in terms of browsing, it was slow, especially when opening new tabs, and got slower when I had several tabs opened.

Here how to make Firefox 4 faster:

  1. Open a new tab in Firefox 4, type about:config. If you get a warning, just click the button.
  2. Then type network.http.pipelining in the Filter bar.
  3. Double click on network.http.pipelining, this will make the value to True.
  4. Same with network.http.pipelining.maxrequests, double click on it, now enter a value of 8 or 10.

Other changes you could make in order to make Firefox 4 run faster:
network.http.max-connections, change it to 100.
network.http.max-connections-per-server, change it to 20.
network.http.max-persistent-connections-per-server, change it to 8.

Restart your Firefox 4 browser, you will notice that Firefox 4 is a bit faster. Opening a new window or tab should be faster. Pages should load faster in Firefox 4 now. It worked for me!


Good guide, there is an awful lot you can do to make Mozilla Firefox work faster a good guide is here
Note it will take a while but well worth it in my opinion.

Tech Helper, I read all of it. And thanks for pointing out the Check Places add-on.

Great blog.

Hey! I could have sworn I've been to this site before but after checking through some of the post
I realized it's new to me. Nonetheless, I'm definitely glad I found it and I'll be
book-marking and checking back often!

Superb blog! Do you have any helpful hints for aspiring writers?
I'm planning to start my own website soon but I'm
a little lost on everything. Would you recommend starting with a free platform like Wordpress or go for a paid option? There are so many options out there that I'm completely confused ..

Any recommendations? Thank you!
