I love Firefox browser (obviously, in view of the fact that I contributed).

If I click the "Add to Firefox" button to add an add-on (e.g. UnMHT 8.1.0), can this action later be reversed and the add-on removed without problems?

In other words, how does one delete an add-on?

BTW, my platform is Windows XP, running Firefox 43.0.4

Please advise, Reed Hansen

There are two types of Add-ons. There are the Extensions that you find and install. And there are also Plugins. These are from other programs that are on your system when Firefox starts. Like video players, anti-virus, and many more. You can disable normal Add-ons by going to the Add-ons Manager,

Type about:addons<enter> in the address bar to open your Add-ons Manager. Hot key; <Control>(Mac=<Command>)<Shift> A)

Select Extensions, locate the add-on. From here you can disable or remove it. Plugins, however, can only be set to Never or Ask. To remove it, you have to remove its program.
