This version for firefox is severely outdated. Not only it lacks newer features but also the text size adjustments don't work.

nice to use. and for Chinese user, I'll say it can translate words!

nice

Reading aloud doesn't work with firefox. the button has been disappeared compared to the version in MS Edge.
Even if it would work, there are only 3 voices availble.

很好，点一下图标就可以启动

A very elegant reading experience

无法启动阅读状态

在Chrome下体验良好，但是Firefox下没有效果，希望能更新
