Dude you just stole my heart with this addon. This is working perfectly as I wanted to. I want to add more User-Agents and OS and others for that I need your kind help. I have emailed you to the support email listed for this addon page.

*** I'm seeking for your attention dear admin of this addon sir ***

I need your kind help to add more User-Agents, OS, Versions etc.

Can you publish an Updated Version soon? Or else You can help me to add manually?
I'm really not aware of user-agents for different browsers and OS.

*** Waiting for your response ***

Sorry for the late response, I didn't see your message earlier unfortunately. The list of shipped User-Agents was recently updated. I do not plan on extending the shipped User-Agent list, since maintaining it is quite a bit of work and don't want to add any obscure entries.

You can, however, add you own entries in the settings (Menu → Add-Ons → Extensions → User-Agent-Switcher → Preferences). In order to find the strings you need I'd suggest looking at http://useragentstring.com/pages/useragentstring.php which has a very big list of those (they are not always up-to-date however).

Sincerely, Alexander

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!

小心使用此插件，该插件可能会导致Cloudflare反复验证

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. 😕

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.
