Отлично работает!
Perfect!

Very good work.
*Please see if you can add On/Off button somewhere easy to access.
*Also if you can add a button to let the user decide when to change the UA, for example I'm on a website with a specific UA and when I load the next page of the same website then the UA changes which it is going to be very suspicious if the system is smart.

Thank you again for the great work.

I'm not a programmer or a tech guy -- but I am concerned about canvas fingerprinting. Question: After installing this extension I re-ran Panopticlick (https://panopticlick.eff.org/) yet my test results did not improve. Is this test not recognizing what RandomUA is doing? My assumption is that RadomUA is creating a new, unique fingerprint and that maybe Panopticlick isn't geared to recognize what is happening. Any explanation would help, thanks!

haven't had any issues with this so far!

Does what it says - spoofs UA string, throwing off fingerprinting.
