Excellent

Almost perfect. I'm having hard times deleting or fixing an engine (which happens to be Google FYI and) whose "Search URL" I tweaked and ended up making it invalid when I added it. Unfortunately it seems users are not allowed at all to edit added engines.

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.

Not working as intended. When I manually enter a search engine and press "Add custom search engine" I get sent to the "Adding a new search engine via the URL bar" page, showing how to add a search engine with the 3 dot menu, but the option in the 3 dot menu never appears for the sites im trying to add. I'd like an option for the manual input to not take me to the 3 dot instruction screen.

Will update rating when this is resolved because this app is really vital for me.

I used to use "add to search bar", it only need a right click on the search box, it was much more easier.

I literally don't know how to use this anymore, I used the form but nothing happened. Then a page was shown to add the search using the 3 dots but then all my customizations were lost and the search did not work. Instead of getting a wikipedia search all I got was https://en.wikipedia.org/wiki/Test every time. How do you use this thing now?

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.
