Sadly Cloudflare security check is not letting me go to the webpage because I am spoofing that I'm on Linux (while my real OS is Windows) it has been working fine for years but not any more. Shame.

The only user agent switcher I've found that reliably works. Allows you to apply custom user agent to a specific domain. UI is simple and easy to understand.

The best user agent switcher. Buffering on Youtube magically gone. Compared to using FF by default that YT will buffer every 10 seconds.

very good at its purpose

Firefox on mobile doesn't have a feature to permanently keep "Desktop site" on, sometimes when the website is unloaded from memory and reloaded the website goes back to mobile view which can be frustrating. This extension is pretty much a fix to Firefox's lack of such feature.

Simply doesn't work on mail.com. That was exclusively what I needed it to do, so that's a total failure.

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!

Aucun effet sur Firefox pour Android, testé sur Boursobank et Renault, le navigateur reste détecté comme un Android
