How to disable Add-on compatibility checking in Firefox 7.0a1 Nightly builds


Firefox have just updated their nightly builds to 7.0a1 and if you want to continue to use your existing Addons, you will be aware that some gentle browser hacking is required.

However, the usual Firefox hack involving extensions.checkCompatability.x now fails. I tried the following entries and the Nightly build ignored them

However, a great post from Daniel, discusses how to solve the problem.

To get your Addons working under Nightly 7.0a1:

  1. Open a new tab.
  2. Type about:config in the address bar.
  3. Right click anywhere on the page and click on Boolean under New.
  4. Enter this as the preference name: extensions.checkCompatibility.nightly
  5. Click OK.
  6. Choose false and then click OK again.
  7. Restart your browser and all your add-ons should be runnable again.

Firefox 4 Search Engine and Tab Tweaks


I’ve been using the latest Firefox 4 beta for over two months now and I like it a lot. In fact, since December 2010 I’ve been using it as my default browser and have even moved to using the Mozilla nightly builds which I have found to be robust.

Mozilla has made a number of changes to the upcoming release of Firefox that some users may like or not. One interesting change was to use Bing as the default search option in the address bar. Personally, I don’t mind it but there will be many other users who may prefer to use Google instead.  By following the small tweak below, you can change the default provider from Bing to Google. Choice is life is always a good thing!

  1. In the Firefox address bar, type  about:config
  2. In the filter box type in: keyword.url
  3. Next, double click on the highlighted keyword.URL entry
  4. Replace any text in the string box and replace with:
  5. Replace the text with the following:
  6. Click Ok to save the new setting

Loading multiple tabs in Firefox can slow down the overall user experience. By design, Firefox runs three tabs in the background. But, there is a manual override to gain better performance.

  1. Locate browser.sessionstore.max_concurrent_tabs in the settings.
  2. Set the preference from 3 to 0. Essentially, It’s a built-in BarTab.

Speeding up Firefox


Type “about:config” in your firefox address bar.

Search for the following settings:

  1. network.http.pipelining  -  Set to TRUE
  2. network.http.pipelining.firstrequest  -  Set to TRUE
  3. network.http.pipelining.maxrequests -  Set to 32
  4. network.http.proxy.pipelining  -  Set to TRUE
  5. nglayout.initialpaint.delay  -  Set to 0

Its very likely that you won’t have an entry for network.http.pipelining.firstrequest. Thats ok. Just add one.

Right-click on the preferences list, select ‘New’ then select ‘Boolean’

On the first prompt, type:

On the second prompt, set it to TRUE

Its also likely that you won’t have an entry for nglayout.initialpaint.delay

Right-click on the preferences list, select ‘New’ then select ‘Integer’

On the first prompt, type:

On the second prompt, set it to ‘0’

Optionally (for even faster web browsing) here are some more options for your about:config (you might have to create some of these entries by Right Click –> New– > Integer or String

network.dns.disableIPv6: set “false”
content.notify.backoffcount”: set “5“; (Five)
plugin.expose_full_path”: set “true”.
ui.submenuDelay”: set “0; (zero)
