Tweak And Hack Mozilla Firefox 4 For Faster Browsing Speed

Mozilla Firefox was a really fast and stable browser until the arrival of Google Chrome and Apple Safari. I’ve been using Firefox for more than 7 years, after years of exporting and importing the same database, I guess it is time to tweak and optimize my database as it gets clustered. The following tweaks are obtained by typing about:config and then modifying the page.

1. To enable/disable Single Click Select URL of address bar

    browser.urlbar.clickSelectsAll = True
    browser.urlbar.clickSelectsAll = False

2. To auto Complete URL while typing in the address Bar


3. To set the number of auto complete URL in the address bar

    browser.urlbar.maxRichResults = #
    (# indicates the number of auto complete URLs shown. The default is 12)

4. To disabler Browser Toolbar Tip

    browser.chrome.toolbar_tips = False

5. To paste copied content by clicking the center button on the mouse

    middlemouse.paste = True

6. To disable blinking text

    browser.blink_allowed = False

7. To create a single close button to for all Firefox Opened Tabs.

    browser.tabs.closeButtons = 3

8. To increase number of recently closed tabs.


9. Right click view source in your editor

    view_source.editor.path= Path of Editor

10. To enable fast scrolling across tabs

    toolkit.scrollbox.scrollIncrement =75

11. To stop displaying website icon in address bar and on the tabs

    browser.chrome.site_icons = False

12. To enable spell check in text fields

    layout.spellcheckDefault = 2

13. To speed up the browser

    network.http.max-connections 30 to 96
    network.http.max-connections-per-server 15 to 32
    network.http.max-persistent-connections-per-server 6 to 8
    network.http.pipelining false to true
    network.http.proxy.pipelining false to true
    network.http.pipelining.maxrequests 30 to 8
    network.http.pipelining.ssl false to true
    network.http.proxy.pipelining false to true

14. To disable annoying browser behavior

    Change the followowing values to ‘false’

15. To show more tabs on single window

    browser.tabs.tabMinWidth = 75

16. To display search results in new tab

    this one doesnt relate to speed but tracking. By default, firefox 4 has a feature called geo, which tracks your location and offers search results based on this, especially google results. You can turn it off permanently. Within about.config just turn geo.enabled to false.

      Firefox needs to be written from ground up, I was hoping that they could release a no addon no toolbar allowed version. Just a simple browser build for speed.
