终于干掉CSDN啦

太好了，终于屏蔽掉垃圾的 CSDN !!

After the mycroft project stopped working, I was completely lost as to how I would add another custom engine. This extension worked like a charm!

Sehr nützlich!
Hiermit kann auch die defekte Amazon-Suche wieder hergestellt werden.

Extremadamente util.

I'd give this 5 stars, except the instructions to use it aren't at all clear.

How I got it to work (to add google.co.uk as a default to google.com) in Windows Firefox v 126.0 64bit:

1) add (ie, install) the extension
2) restart FireFox
3) Right-click search box. You'll then be given the option to add a custom search; click this, then enter the details. Finish.
4) go to firefox->settings->search and your new custom search engine should appear at the bottom of the "Default Search Engine" drop-down list. Choose it.
5) Voila!

I don't like running extensions when not in use, so I turned it off. When I restarted FireFox, my choice (google.co.uk) was still active.

Thanks @Tom Schuster

Works like a charm! I was sad when I thought Firefox didn't have something that Chrome did—but this fills that gap!

以前、Ready2Search　を長年使っていたが、提供しているサイトが閉鎖。結果、Add custom search engineに辿り着いた。Firefox内では、検索サイトをオリジナルで作れないので、今後は、オリジナルでも追加できるようにしてもらうとありがたい。しかしながら、コレはお気に入り♪

Works really well
