Very good

perfect

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

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 :-)

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 :)

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