User-Agent Switcher by ntninja

Review by Firefox user 13522774

Dear Alexander Schlarb, I hope you receive this message. This agent switcher is by far the best I've tested at present. It gets the information correct on the sites I've tested it on. Other add-ons will show a different agent yet reveal under system information my real system information. Your add on doesn't. There's just one thing I would really appreciate, if possible, to set custom screen resolution, is that possible? I hope this review reaches you. Thanks.

Thank you for your feedback! Unfortunately this kind of feature request is totally ill-suited for the review section as it needs a lot more discussion and justification to be added to this extension. Please open an issue (with details and your particular use-case) at https://gitlab.com/ntninja/user-agent-switcher/issues/new so that we can discuss this properly.

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 Mister ntninja update the extension please!

Please add a redefinition for Yandex Browser (Window), because I'm tired of seeing annoying ads in Firefox every time I search!
PS: Windows / Yandex 25 [Desktop]: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:135.0) Gecko/20100101 Firefox/135.0 - didn't work

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.

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
