Easy and decent User-Agent switcher. But missing an overview function for the exceptions / overrides i make for the many domains i visit. Now it is only possible to view/add/change an override if you are on the specific website.
An other thing which can be improved is the user agent set. After installing this addon i did not notice any updates (like version number increments) on the set of user agent strings, you have to do this yourself. [i was wrong, there are some weekly/monthly updates]
But the Firefox user agent is not correct: "Mozilla/5.0 (X11; Linux x86_64; rv:115.0) Gecko/20100101 Firefox/115.0" should be "Mozilla/5.0 (X11; Linux x86_64; rv:109.0) Gecko/20100101 Firefox/115.0" see the rv:109.0 reference.
Beside that, working great!

Easy to use (although a bit confusing if you're using it for the first time) and does as advertised.

The only issue I've seen recently is that videos on YouTube stop playing after a few seconds and an unexplained error prevents the video from playing every single time. Disabling this add-on instantly resolved this issue. I will change the rating to a 5-star as soon as I find a way for the addon to work again without this disturbance, or this issue is patched.

I have changed to a different agent switcher as this one causes a Cloudfare verifying continuous loop.

I use this extension for many years now. But sadly the development is very slow. It's very outdated, you're stuck with very old and on many websites not anymore supported browser-versions to choose from like Firefox 134, Firefox 128 ESR, Safari 17, Edge 131. Also no matter which browser you choose from, on browserleaks.com/javascript its still possible to see that mozilla is used (the parameter appCodeName shows "Mozilla". So please ntninja update the extension!

Edit (2025.11.05):
In it's actual deprecated state this browser extension breaks the Cloudflare Bot Challenges.
If a website uses any of Cloudflares Anti-Bot Challenges it will break the website and render it useless.

Please add a redefinition for Yandex Browser (Window), because I'm tired of seeing annoying ads in Firefox every time I search!

doesnt keep itself isolated using "only for this site" pref. Apparently it enables selected UA for *all* sites, and for ones you didn't want you have to opt-out... Not best UX

This used to be the most functional useragent-switcher (even if the UI/UX was left wanting), but even this doesn't seem to work anymore. 😕
