Thanks for telling.

What site are you using it on? On video or audio? Yes, the standard right click context menu.

I don't know if it's possible for you to reply to my reply here. You can edit your review and I'll re-read it. Or email me.

This thing doesn't work on Soundcloud at least, since they use a different way of serving their music. There are other websites like that too. Works on Youtube so that's a good place to test it. On youtube, the first right click brings up youtube's own context menu. Just open the context menu again and firefox should open the regular menu. There you can then see the custom loop menu.

edit: that is weird. I'm now on ubuntu and I see it fine. Can you see context menu items for other addons?

Try this: https://addons.mozilla.org/en-US/firefox/addon/right-click-wiktionary/ . Select some text and right click it, you should see a Wiktionary thing.
