Disable Firefox 8 Add-on Compatibility Checking

By XPS on November 19, 2011.     What do you think of this article?

In an article I wrote last April concerning the Firefox 4 add-on compatibility checker, I explained how to quickly disable said tool in order to allow older add-ons to run. That tutorial worked great for Firefox versions 4-7, but it has to be updated for Firefox 8. In this tutorial, I’ll walk through removing the old configuration and adding the new.

• 1.) Open up Firefox’s Configuration page by typing about:config in the address bar. Read the prompt and click the button saying you’ll be careful. (See how to re-enable that warning prompt)
• 2.) Inside the filter field, enter in extensions.check to shorten the list of preferences
• 3.) Right-click the extensions.checkCompatibility.4.0 preference and choose the Reset option. You will notice the Type changes from a boolean (True/False) to a string and the Value goes blank.
  
• 4.) Create a New > Boolean with a preference name extensions.checkCompatibility.8.0 and set the boolean value to False.
• 5.) Restart Firefox and your new preference will function just as it did for Firefox 4-7. The old preference you reset also disappeared from the Configuration page because it was an empty value.
