One of the most useful aspects of the Firefox web browser is that its architecture lets developers create software add-ons to customise the browser and add many useful features that are not provided as standard (for example, to improve privacy, or provide tools for web developers).
Add-ons which are particularly useful include:
|RequestPolicy||Prevents content from third-party sites being loaded on the site that you are visiting (for example buttons and content from social network sites which track your movements around the web, data-gathering adverts, and so on).|
|Flashblock||Prevents Flash content from running automatically (unneeded Flash is quite CPU-unfriendly, especially on Linux).
This add-on is not needed if you have NoScript, but it is a simpler solution if you do not.
|Firesizer||Lets you resize your browser window to a specific size (useful for web development, or if you’re just finicky..).
(In Firefox 31 or newer, The Addon Bar is also required (as this has been removed from Firefox).)
|Neo Diggler||A “go up” arrow for navigating hierarchical web folders more easily.|
|It’s All Text||Lets you open textarea editing boxes in an external editor.|
|Firebug||Web developer debugging and code inspection tool|
|Colorzilla||Colour picker tool, useful for editing stylesheets or transferring colour values from and to images.|
|Cookie Controller||Lets you quickly set cookie acceptance options for individual websites, delete cookies, etc|
