Sync search engine settings

[Arvid]

It would be nice if I would not have to set up all my search engines and their short codes with every new installation but could sync them just like my add-ons and history.

Thanks @IndefiniteBen! Copying search.json.mozlz4 to another pc/installation works like a charm.

Integration in Firefox sync would still be a much needed addition, though.

Remember sites, keywords? I can't even get google to explain “keyword,” but you're already on a computer, and you don't screen grab the info or enter the info to ff and Notepad? I Notepad lots of my system settings, when I have to, and google syncs them, but quite possibly I'm missing something about this.

140.0 relnotes mention "Custom Search Engines: Firefox now supports adding even more search engines. To add a custom engine, right-click a search field of a supported website and select “Add Search Engine”, or go to Settings > Search > Add…"

I kinda hoped that would also bring in sync, but apparently still not 😞

3 years ago @Jon had "exiting update"… that the issue is trending. Well, d'oh!

It would be nice to have though I guess lack of any sort of search engine customization on android could be a problem. But having it sync would be great start...

what is going on? this is an extremely low hanging fruit that I cannot imagine are withheld for any real reason other than bureaucracy

Looking for the day I can get rid of my search bookmarks and rely on the custom search engines in the settings that have the nice UI but that's not happening until it get synced

It's so weird to have custom search engines features duplicated in two different places (bookmarks and settings), people it's all there, just unify the thing

Same with the profile feature than you can get from about:profiles and from the menu... but they are not the same...

I would love to see this get added

It's Nov 2025 and folks like myself are still coming here because we're finding that when we set up an elaborate custom search engine configuration, we have to manually set it all up over again on every other device we have or work from. This becomes a frustrating and arduous task, and I thought this was the whole reason for sync to exist in the first place?

If it's really as easy as just copying over search.json.mozlz4 to our other machine, then why hasn't this been implemented with sync yet? Is it because of revenue-generating contracts for default search engines? Because some of us came over to Firefox to get away from that kind of thing...
