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.

Don't get your hopes up, this was first reported 14 years ago.

In the meantime, there is a workaround for this that's easy enough [source]:

Workaround

Assuming copying from one PC to another

1. Close FF on both PCs
2. Navigate to your profile folder on the old PC: %APPDATA%\Mozilla\Firefox\Profiles\
3. Find file search.json.mozlz4
4. Copy file to USB/Cloud Service
5. Download to new PC and copy to your profile folder (replace the existing file)
6. Open FF on your new PC and enjoy your search engines and keywords

Note: when I reopened FF after doing this my default search engine had been changed, so you may need to manually reset the default.
