Work, 👍

Since a few weks it breaks youtube. It manipulates cors in a way that youtube will not load past the minute mark

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

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!

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

Nice addon helpful on some websites!

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