Great, thanks! I'd like a feature that when used on top of Firefox for Android, would automatically set the UserAgent to the desktop version of the site depending on whether it's open or not. For example, when the desktop version of the site is turned on, the Linux and Windows Useragent is generated, and when it is turned off, the Android one is generated.

it fixed my ban status on a site!!!!

This new update is not working. Please upload the previous version it works well. This update is not stable.

The last version "improved" the extension so much that it stopped working. It doesn't matter what user-agent it shows - browser tests always return the original one.

Could be the best UA changer out there if it worked. Something broke or there are unknown conflicts (Multi-Account Containers?). Some other extensions of this kind I tried also don't work.

So-so. When it works very good, but often randomly does not work and then i have re-install, switching on-off etc... Unreliable operation ...

The add-on button shows the random UA, but the web pages still see the actual UA.

I really like the extension, it works great. The problem is, when im on my android phone and it chooses to spoof my device as a tablet, websites show the tablet/desktop version even though i choose only androids. I understand that it would compromise some of my privacy, but i would really appreciate if you would add a switch where it would only spoof my device as a mobile android phone, as it would solve a convenience issue.
Thank you!

Great, it works and it is very simple and easy to use.
