This user-agent switcher saved me a lot of reboots. I am running a dual boot Windows 10 / Ubuntu environment. I needed to use a website that doesn't validate Ubuntu as a compatible OS. Now I can use that website just by switching the user-agent to Windows. Great work! Thank you for making this add-on.

Très pratique, fonctionne avec Instagram, Youtube, Amazon...

good gan...

It's fairly good, but it has some big issues:

(0) *** It needs to allow per-site overrides. You should be able to set a global user-agent string, but override it with a different one for specific sites. ***

(1) It doesn't get regular updates to keep the user-agent string up-to-date with new browser versions.

(2) If you modify the string of a combination of OS+browser, there is no way to reset it to the default, and the change will be retained even if uninstalling and reinstalling.

(3) No option to save a custom string; if you change the agent, the custom string is lost.

(4) No option for random agent.

It's not work on Firefox for Android

he很不错

it's interface is easy and friendly, but you have to update UA strings because many websites break and say that my browser is old and not supported, which makes the addon useless.
