Works in Zen too! :)

The only user agent switcher I've found that reliably works. Allows you to apply custom user agent to a specific domain. UI is simple and easy to understand.

The best user agent switcher. Buffering on Youtube magically gone. Compared to using FF by default that YT will buffer every 10 seconds.

very good at its purpose

Firefox on mobile doesn't have a feature to permanently keep "Desktop site" on, sometimes when the website is unloaded from memory and reloaded the website goes back to mobile view which can be frustrating. This extension is pretty much a fix to Firefox's lack of such feature.

Great add-on. You can apply user agent switches per domain. It worked at first try on YouTube. The icon colour will change accordingly whether there is a switch applied per domain or general. Way clearer than 'User-Agent Switcher and Manager' by Ray.

wow. this is better than User-Agent Switcher and Manager and UI is better. Also that works only single website if want. Great job 👍
