Useful addon.

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

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.

I really love this, should've just been built in but now I can use https://searchthat.net/search.html?q=%s without problems. Thanks.

Does the job perfectly. Thanks.

Great addon.

Worked perfectly. Thanks! (PS use SearX!

It should be built in to firefox. Great and easy to use addon.
