Ocena uporabnika Patrice

So easy to use, unless you have a serious brain disability but in this case you should be in a specialized hospital (yep a read some 1 star reviews = UNBELIEVABLE about why they put 1 star!!!)

A top of the line add-on, strongly recommended!

Yes sure we would like more options in the user agent or more operating system and browsers choices, but it's just to be able to put more mess with websites who spy on us... I got an idea why not an input where we can input a "home made" user-agent ROTFL hahaha ;)

In all case this add-on spoof very well Instagram to upload pictures from your desktop computer, just select any smartphone, reload the page and you are set with the + tab/button at the bottom!!

Thanks a lot Alexander Schlarb, it's very good add-on

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. 😕

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.
