Only works for direct URLs. Continues to pass on the default UA for any page resources (JS, CSS, images, etc.) Sadly it's now how it is supposed to work.

This one is saving my life when using office web.. it's sad to see office web forcing edge to be used... I really love this extension.

Thank you

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

When I try to log in to discord.com, the screen turns blank and I can't get in.
If I turn off this add-on I can log in, so I think something must have gone wrong with a recent update to the add-on.

Very usefull, but UA data are too old, and I can't edit config which I added, only way is remove first then re-add it

Worked perfectly no issues. Simple and sweet.

Update: New version is broken, install 0.2.1 instead.

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

Works mostly as described. Unfortunately it doesn't seem to support wildcards (*) in url patterns, meaning eg every subdomain of a given parent domain must be listed separately, which is not convenient.

Very awkward to use. It can't be activated for the current Page/site, but, instead, its address must be manually added to the list of the desired agent string, what is possibly the worst way to implement it (what if a site matches more than one list, the first string is selected or does it randomise amongst all matches?) I also had problems using * as a wildcard, forcing me to use full URL.

priority not working anymore

This add-on functions as the name says.

Gripes: The add-on is not suited for small screens, especially on Android, as some of the Android phones' smallest screen resolutions are only 240x320px in size.

this crap is totally unusable

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

The addon works like a charm and it is the most powerful when it comes to change UserAgent.
Definitely a must-have for advanced users in the need of this feature.

However, i believe, it could have a simpler settings' page if one could have a combo box for Platform Selection, another for OS selection and another for Browser Selection, all separated from each other (leading to the final User Agent String).

That would work kind of a "step-by-step wizard" that would avoid the actual very (VERY) long options' combo box that might scare new users...

Working

Thanks

Sorry this addon does not work either. And its UI is cumbersome, why do I have go to addon settings to set UA? Cant this be done in a popup?

It's not work on Firefox for Android

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