Sir I've already posted my appreciation for this super fine Firefox browser. As a an absolute novice of internet browsers I usually use both Chrome and Firefox in my Android phone. I'm new to computer science and usually Use these two browsers for downloading IDEs,SDKs, Utility softwares and other Necessary software and Technology- related documents and not for anything else. My request is There are many hidden and unknown options in these Two browsers like chrome://flags in Chrome browser and about:config in Firefox browser As an absolute novice all I can do is to protect myself from unknown harmful websites by using your images-blocking option. There are other options too in your Firefox browser extensions and add-ons which are Extremely Complicated to Understand as a novice now. Please provide me a detailed Documentation in the form of a pdf about all the available options in this beautiful Browser including addons, extensions and about:config. I'll be waiting for your response.
