What does one do with downloaded add on .xpi files?


Windows 8 OS

Downloaded some add-ons--they were downloaded as .xpi files to my DL folder..

'DoNotTrackMe', 'NoScript, 'EasyUTubeVideoDownloader', 'Greasemonkey' and 'FoxyProxy'.. Should they be automatically recognized by Firefox (they're not)?

As far as I can tell, DoNotTrackMe and EasyUTubeVideoDownloader are available.. Should I assume FoxyProxy is running in the background upon opening Firefox? How about NoScript? Same thing?

But GreaseMonkey--shouldn't I have a new menu for that within Firefox?

Thanks for any help.

Lastly-I forgot-TheUTubeDownloader--it is not working either-it is in my add-ons, and enabled, but is unavailable to record while at youtube videos..there's no menu to download..

It is usually best to use the install button on the home page to install an extension.

You can install extensions that you have saved locally by dragging the xpi file in a Firefox window or use File > Open File or Firefox > New Tab > Open File.

If you only saved those .xpi files to disk then they are not installed in Firefox.

Thanks..I figured much of these things out with further poking around shortly after I asked.. Thanks for the help.
