Worked great, thank you VERY much!

I like the simplicity. This addon should be part of firefox. Its easy but very usefull for powerusers.

too slow

You should really get a firefox recommendation tag for this addon.

Useful addon.

Adding a custom search engine was really easy and worked flawlessly. 5/5

页面搜索框的检测并不灵敏，很多时候是手动添加。

This really should be a default feature in the Desktop browser, especially since this is how Search Engines are added in the Android version, but whatever.

didn't work on my device.
