It's a must have extension. This should be a native function imho, but this extension make the work and make it very well. Thank you!!! :)

edit: figured it out, though seems quirky
Used to work now I get this: 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. just like the other guy, will also fix the rating if the issue is fixed.

thanks for this!

Hi Tom,
Is that possible to transfer configuration in any way?
Even to save search query somewhere will be a great solution.

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.
