I love this extension, but I had to roll it back to 0.2.1 for Discord to work. Something broke.

Worked perfectly no issues. Simple and sweet.

Allows domain or URL-specific spoofing, exactly what I need.

It now works after I've restarted the browser three times. Don't know why :-)

Working

Thanks

Its a awsome addon,i can chose my private ua though it,but only for more experience user

Works, but setting a default user agent (by using *) will supersede all custom domain rules.

Perfect, 100 % function.

Giving it five stars because it actually works in the new firefox versions. It's a bit awkward having to go to the addons page to make changes, be nice if there was a toolbar button for easy access but it seems as if web extensions are all doing this.

The addon itself does the job however. I particularly like being able to set unique agents for specific sites. This is coming in handy right for now for youtube since by using an IE11 string I'm automatically getting the old format back. I know this won't last but as long as it does I'll make use of it.

Does what it sets out to do.

Works for me. I can add rules. So, this rules changed User-Agent headers.
