When you open Firefox up in the left hand corner there is a drop down box that says "Firefox". Click on this and go to add-ons a new page will open with tabs on the side. Click on "extensions" then go to the add-on you want to remove and there is a button on the right that says "remove" then follow the steps Hope this helps, Jeremy Eramian

Note that Plugins are not installed in Firefox like Extensions and Themes are.

Maddening. Re; "When you open Firefox up in the left hand corner there is a drop down box that says "Firefox". Click on this and go to add-ons a new page will open with tabs on the side."

That does not happen that way. (I am on Firefox 19.0 for MAC.)

When I click on Firefox (left hand corner at top of screen) "ADD-ONS" does NOT appear.

I get "preferences" and "services" plus, of course ABOUT/HIDE/SHOW/QUIT choices.

Running through ALL choices in PREFERENCES (which was not included as a step in your description) I find NO WAY to "deal with" ADD-ONS in General, Security, Privacy or Advanced.

I KNOW that I have an "ADD-ON Manager" I can open that. The ADD-ON that I need to REMOVE/Uninstall/Disable does NOT show there.

It is an ICON on the lowest level of my toolbars showing above my window. Whether this is an awesome bar, or any other specially named bar I can't tell you, but: LOWEST section.

This creepy ADD-ON (that I never personally installed) is called PRICEGONG - and it is now opening up a pop-up on all my eBay pages and elsewhere.

It is wasting SO much of my time and I need to get it gone. WHAT do I do now? The PRICEGONG company has explanation of what to do to uninstall, but (no surprise) THEIR instructions/steps do not match reality either. RESULT: I can't get RID of this thing and am wasting huge amounts of time now with it. WHAT CAN I DO?
