Not sure if this is for mobile, but does about:permissions work? (put about:permissions in the urlbar and load it.

Note that about:about will probably give you a full list of all available about pages.

Well, you can clear ALL site-specific permissions from the Settings page. Not aware of a method to edit one site at a time.

Menu > Settings > Clear private Data

Uncheck everything except the last item, "Site settings" and tap the Clear data button. When I test using http://www.google.com/ and tap the link Use precise location, I get prompted again, so it seems to work.

Any luck?

Thanks jscher2000 for the suggestion. I wanted to avoid clearing all data for all sites, but I did find a way to clear data for a specific site:

While at the site in question, long tap the URL bar. This will bring up a menu which allows you to clear that site's data, and specific permissions that have been set for it.

Once I cleared the permission for location data, it asked me again to share my location, and everything was good.

The long-tap URL bar option should really be documented somewhere...

Hi knw257, I'm glad you found that.

This site's Knowledge Base is a wiki so you can mark in edits or post a comment. For example, you might add something to this article using the Edit tools in the left column : Clear your browsing history and other personal data on Firefox for Android On the other hand, perhaps there should be a separate article on site permissions?

Hey gtdmouse

What specifically didn't work for you?

the about:permissions answer. I made that post before I saw the other one that worked.
