OMG it instantly solved problems i've been having for years!!! thanks!

very good and it fixes slowness on youtube, but captions dont work now???

很好，操作简单，点一下就伪装成 Chrome 了。印象笔记本来不让使用的，用这个插件开启伪装后，就能正常使用了。

works well! thx

Works Extremely well!
Finally fixed my slowness on Youtube THX!

Overall seems like a good extension but my biggest problem is when used on google for example it requests desktop website instead of mobile we should be able to select whether we want mobile user agent or desktop in extension settings, quite unstable in firefox android because of this reason.

Edit: Developer fixed the issue and thanks to them for responding if they can implement desktop user agent when clicked request desktop site to extension like they have said it will be 5 out 5 extension for now it is 4/5 still very good worth checking out.

Today, Audible decided it didn't want to run its web player. This fixed it.

Nice addon helpful on some websites!

every website can still detect it's firefox

Works great when a site "isn't supported" for Firefox
