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

小心使用此插件，该插件可能会导致Cloudflare反复验证

非常感谢，它自由度高。

Thanks, I can see high quality Facebook Reels on Firefox because of this extension

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

Doesn't fool Netflix

Very usefully.

Plante instantanément Firefox mobile.
Instantly crashes Firefox mobile.

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. 😕

Although this extension doesn't solve my issue completely (hating how Facebook looks and works), I am able to easily convince FB that my laptop is a mobile device which makes it more tolerable.

I love it, I use the user-agent switcher because sites like Roblox believe firefox is "suspicious" and will serve you 10 Captchas if you are on Firefox

Does not work at all. Sites still see my browser's original version string.
