by Firefox user 13998002, 8 years agoThis extension is fantastic! I didn't check all of the settings that are included with the extension but what i needed it for it did superb!
I use Firefox for Android on my 18" Samsung Android Tablet and I get tired of having to check the little box to get the desktop version of websites. Like Google, for instance, I prefer Google's desktop version of their site over the mobile version, especially when the search results load.
I tried to find a way to make the desktop site the default of Firefox for Android and there is an extension that does exactly that but it is incompatible with my device so i did a little thinking outside the box. I remembered there used to be a way to make a web browser, as well as the device it is installed on, appear to a web site to be different than the actual device and browser being used. If a web site detects I am using Linux as opposed to Android which is what I am really using, then it would show the desktop version of it's site since Linux is only installed on a desktop pc while Android (although a variant of Linux) is only installed on mobile devices.
It worked! If need be I can also switch back to Android or just switch it off too! The Windows selection didn't work for me on my Android Tablet but there's other options to choose from. Thank you so much for this extension!

- Rated 1 out of 5by Vykro, 10 days agoThis extension does way more harm than good.
While it does seem to do what it claims to be doing, in practice using this is shooting yourself in the foot.
This is because it appears that with this extension active and set to pretend to be a different browser, websites perceive you as a bot.
On a vast amount of websites you will run into an impassable cloudflare captcha verification screen. You try to solve it - it fails and loops back around. It will keep failing until you deactivate this extension.
On youtube, any comments you leave will be automatically shadowbanned. Presumably because it detects you as a spam bot.
So I honestly don't see much point in using this. - Rated 5 out of 5by Ana, a month ago
- Rated 5 out of 5by Cyberdyne, a month agoOn the surface, a simple extension. Underneath, a powerful extension that enables you to view websites often in ways that run faster and disable pushing their APP to your phone. I consider it more advanced power user stuff, so I do wish there was a way to simplify things visually for more people to enjoy the advantages here. Maybe even a built-in database of known good user agents per website.

- Rated 4 out of 5by fgxxr, 2 months agoEasy 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. - Rated 1 out of 5by Firefox user 19581717, 2 months ago
- Rated 1 out of 5by Firefox user 16549430, 2 months agoI have changed to a different agent switcher as this one causes a Cloudfare verifying continuous loop.

- Rated 2 out of 5by Xenofox, 4 months agoI 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. - Rated 5 out of 5by Firefox user 19437637, 4 months ago
- Rated 4 out of 5by ArtchibalD, 4 months agoPlease add a redefinition for Yandex Browser (Window), because I'm tired of seeing annoying ads in Firefox every time I search!

- Rated 5 out of 5by E.C., 6 months agoThanks, I can see high quality Facebook Reels on Firefox because of this extension
- Rated 3 out of 5by Nocturne, 7 months agodoesnt 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
