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

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.

Works great to fix YouTube illegally slowing/breaking functionality on browsers other than Chrome. However, it completely breaks functionality in Google Docs, making it impossible to type in a document while the add-on is activated. As someone who does a lot of work in docs, this is a really significant issue, so a fix would be appreciated!

It works in Mozilla Firefox 129.0b9 x64, but it is sad that it is impossible to directly edit the list of domains and the User-Agents assigned to them.

Please, add other browsers, yandex, opera ...etc.

Seems ok but Edge browser is stuck on a very old version.
It would be nice to be able to enable (the agent switch) to a single tab

Worked great for YouTube, until they caught on and started blocking me (they showed the same default page "allow YouTube ads") anytime I had this set to Windows/Chrome :(

Good, but for example Edge browser is stuck on a very old version.

Needs an a dedicated on/off button, it blocks the cloudflare human verfication

Works great but it seems to cause problems with Cloudflare's website protection now. For example, going to https://www.podchaser.com/, the Cloudflare check just keeps resetting after clicking the "confirm you're human" check. Disabling the addon makes the Cloudflare check not appear at all

bro i am trying to test it on this website
https://webbrowsertools.com/useragent/
its saying
UA string detected by [normal] navigator.userAgent is different from UA string detected by [aggressive] iframe navigator.userAgent
What to do to hide it from being detected by iframe one . Thanks G

Does what it says, but this only works for "dumb" browser checks

Practical, especially if you want to upload something from your PC to Instagram. Even now, when I want to use Teams in the browser, I can do so despite Microsoft's disabling, because I pretend to be on Edge. I noticed that the Chromium-based Edge is still missing and only the old one is available.

where is white list/black list domains? so, its only full switching for all sites?

GUI awesome, but ...(

Does what it is intended. However, I would prefer if the user agent selection is somehow limited only to the tab where it was selected.

Works very well but the user agents have outdated browser versions.
