Why add better safety at Firefox; Every time you connect to a website using any program tours, the website automatically collects a lot of information from your computer. Although not all websites process or record the information, some of them may well use it to locate you and for other purposes such as targeted advertising.
If you are worried enough and want to know more, there are Web services such as the Panopticlick of the EFF that tell you what information websites collect when you connect to them. The information you unwittingly share may include your operating system type, your web browser and version, your screen size, fonts,series of your system or what plugins you use.
What you could do quickly and simply is to install it Random Agent Spoofers in your Firefox. This add-on will send false information to the websites you visit.
As for plugins, web pages can only detect plugins that are enabled in your browser. So while you can - and should - disable plugins that you do not use, you can not block information sent by plugins that are enabled.
This can be changed by a Firefox add-on: Hide Plugin & Mimetype which you can install in your browser. Once you do, there is no information from the plugins about the websites that collect them. The Results of the add-on you can check them on the Panopticlick website.
How do they help all of this?
It should be noted that the add-on Hide Plugin & Mimetype does not prevent the operation of plugins. You can specify which plugins to run, you can prevent plugins from running automatically for a more secure browsing.
Blocking information prevents websites from using plugins to identify users. Websites as much information can gather, the more likely it is that they can create a unique footprint of the user to be able to recognize it even without the use of cookies stored on his computer.
