How to Set Restrictions in Mozilla Firefox? Restrict Downloads, Adding Bookmarks, Add-ons, Changing Options, etc

Many times we want to restrict other people from changing our customized settings. We change various options to meet our requirements and suddenly someone comes, uses our system and modifies the settings. It takes lots of time to remember the previous settings and re-apply them.

Same case with our web browsers. In this topic we are going to talk about Mozilla Firefox. We'll learn about how to:

Restrict Downloads in Mozilla Firefox
Restrict Add-ons in Mozilla Firefox
Restrict Options in Mozilla Firefox
Restrict about:config in Mozilla Firefox
Restrict Addition of Bookmarks in Mozilla Firefox
Restrict History and Bookmarks Sidebar in Mozilla Firefox
Restrict "Clear Private Data" window in Mozilla Firefox

Wouldn't it be great if we can have a single tool which can set one or all above mentioned restrictions in Firefox in a single go? Actually you are very lucky today.

We found an interesting add-on "Public Fox" which allows you to set various restrictions in Mozilla Firefox.

You can download the add-on using following link:

Download Public Fox Add-on for Mozilla Firefox

Once you install it, you can access it using "Tools -> Add-ons -> Extensions". Select the add-on from the list and click on "Options" button.

As you can see in the above screenshot, you can set various restrictions using a Password. After applying the restriction, whenever you'll try to access a restricted feature, you'll be prompted to enter the password.
