As you all know, millions of add-ons have been developed to give extra features to Firefox browser, which don’t come by default. Users install these add-ons without having any knowledge about how they are going to work. These add-ons can change Firefox ‘about:config’ preferences without your knowledge.
Many Firefox users have been complaining about add-ons over the last few months which suddenly changed Firefox preferences without their knowledge. The solution to this problem is ‘Preference Monitor’ add-on, as this simple extension watches for changes in the ‘about:config’ preferences on Firefox browser and alerts you of what was changed exactly.
There are three scenarios regarding changes:
- Changes made by Firefox itself.
- Changes made by extensions to its own preferences.
- Changes made by extensions to private Firefox preferences.
‘About:config’ contains most of the Firefox configuration option. Any changes in the ‘about:config’ settings could dramatically affect Firefox browser ability to work without hassle. It’s a must have add-on for Firefox browser, so that you could know about the changes made in ‘about:config’. You can download and install ‘Preference Monitor’ add-on from the link below.
