Works well. Thank you man!

Great addon! A must-have for me, it saves my Firefox

Well, problem doesn't reproduce anymore, so, I guess bad luck. Thanks for your work.

(in the meantime, did things another way : directly uncompressing search.json.mozlz4, manually editing and recompressing. takes a bit of time but gets things done)

Man, I was about to uninstall Firefox and go back to Chrome thieves, for the lack of my country localized Google search engine in Firefox, that I just couldn't find. This extension saved the day. Thank you so much.

All what I want. I don't understand why mozilla does not include the custom search engines as feature.

Was alarmed to learn that Mycroft Project search bar options no longer works, while recreating my Firefox profile. Apparently Mozilla is depreciating Opensearch XML addon support? That's dumb.

Found this extension and it does the job of creating custom search bar options perfectly. Highly recommended!

A great tool that perfectly does its job

It's a shame Firefox no longer lets me add DuckDuckGo UK (I used to be able to search on here and add it just fine), but this extension helped me. Mozilla Firefox has really dropped the ball here. Well done Tom Schuster for enabling a customisable work around.

Doesn't work on Firefox 78+ and had to use "Add Search Engine from Mycroft Project" instead.

Edit: Works now, thanks for prompt fix.

tks, working perfect for searching product on marketplace
ex: tokopedia.com, bukalapak.com, shopee.co.id, lazada.co.id

is there a way to synchronize custom search engines between different devices?

Think back to the days before rolling releases and remember the simpler times. Times when you could add any site to your search bar in a single click. Those were good times. This gives you a dose of that sweet nostalgia of having a powerful URL bar, but with the added fun of being able to customize the handling a wee bit more by yourself. I hope some day we'll even get to a point where we can set keywords ourselves.
