Nice, but the default shortcuts could be better.

You can set Ctrl+Right and Ctrl+Left yourself using about:addons -> Settings icon -> Manage extensions shortcuts

可以设置 f2 f3按键，切换tab页面， f3是firefox的。。。最后只好用f1 f2了

Should just be Ctrl instead of Alt+Shift.. which is not any practical.

Especially when you can simply use Ctrl+PageUp-Down(keys) todo the exact same thing ..
