பயர்பாக்ஸ் ஆதரவு மன்றம்

On the Total Adblock site it gives these directions for removing the program: "Mozilla Firefox Uninstalling Adblock from your Mozilla Firefox browser is very simple and can be done within a few clicks. Go to the Extensions Page on Mozilla Firefox copy this link into the address bar of your browser:about:addons

Find Total Adblock within your plugins . Click the 3 Dots. Click Remove."

I do not know where the "extensions page" is. Nor where to find it. While I have been using personal computers for decades, I am still a complete beginner when it comes to any technical jargon. If someone would kindly give me directions in English about getting rid of this annoying extension/program? I would deeply appreciate it.

The extension Password Manager XP was installed on 3 computers running Firefox and the program Password Manager XP. Recently on one of the computers the extension disappeared and as a consequence the program's right click menu integration stopped working in Firefox, though it does on Chrome and IE.

How can find and/or download the extension and reinstall it on the affected computer?

Thank you
