perfect

Very powerful, with a very deep selection of user agents that you can easily sort through based on OS and browser. Blacklist, Whitelist, and Custom filtering is available in the addon options, though curiously you have to choose between the three instead of having a combination of them. No way to bulk add user agents is the only real downside to this addon, but when it comes with such a large selection to begin with this won't inconvenience many.

I do recommend the Dev add a shortcut from the popup to get to the addon settings though.

In addition to choosing OS type and browser type, it allows to choose both the OS version and the browser version. Everything is provided as a pre-configured strings.

Very good spoofer. Use it to work around Facebook messenger. Only problem is that I can't get the whitelist to work.

user-Agent很全

It lacks the functionality to specify a user agent for individual URL. There are already extensions that have this implemented. Other than that, it works and the UI is nice. Mixed feelings.

Thank you.
Do you plan to change the user agent randomly?
By now I have to select a user agent at the start and after some time.
A blacklist and whitelist for certain sites would be nice too :-)

Needs an option to export custom strings from an XML, so it won't need updating once in a while.
Overall, looks pretty solid.

Incómodo de usar, dependiente de Internet para buscar en una base de datos que, encima, está desactualizada.

Very user friendly interface. Before i use other addon, but without option to select version of browser and etc, just only select os and browser.

just works :)

Wow it is easy to use and portable too. thank you!!

so good and portable.
there are many UA lists to select

So muvh
