No, you turned on a hidden setting on your old Firefox, and that didn't Sync over to your new Firefox. '''Setup: Enable adding search engines by URL''' (1) In a new tab, type or paste '''about:config''' in the address bar and press Enter/Return. Click the button accepting the risk. ''More info on about:config:'' [[Configuration Editor for Firefox]]. ''The moderators would like us to remind you that changes made through this back door aren't fully supported and aren't guaranteed to continue working in the future. Since I use it myself, I feel comfortable mentioning it.'' (2) In the search box in the page, type or paste '''browser.urlbar.update2.engineAliasRefresh''' and pause while the list is filtered ''Firefox should display a bar with Boolean Number String and a plus sign button.'' (3) Keep the selection on Boolean and click the plus sign button. If the value isn't set to '''true''' automatically, double-click false to switch it to true. '''Create a New Search Engine''' Open the Settings page, Search panel, and scroll down to the Search Shortcuts section. Below the box, you should find a new '''Add''' button. Here's where the (not fully baked) magic happens: Click Add to open a form and then set up your new engine with the name of your choice, your results page URL, and keyword of your choice, if any. '''The results page URL requires editing:''' replace {searchTerms} with %s in the URL. This is an example from another thread: <img src="https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2022-01-24-17-00-59-305e5b.png"> Note: there's no way to edit this new search engine so if it doesn't work, you would need to remove it and create a new one.

Thank you 100 times!! That worked :)
