Convert Firefox smart keywords into Opera search engines
Explanation
Opera doesn't support Firefox Smart Keywords. When you import Firefox bookmarks into Opera, you lose the ability to use any bookmarks with a "%s" in the URL to search. This page changes all the smart keyword bookmarks into the search.ini Search Engine format so they'll work in Opera. Tested with Opera 10.62.
Instructions
Export your Firefox bookmarks as HTML
Paste the resulting HTML in the top text area
Open %USER_PROFILE%\Application Data\Opera\Opera\search.ini in a text editor and scroll to the end
Back up search.ini just in case
Enter what the next search engine number should be in the Starting Search Engine Number field
Hit convert (each bookmark with a "%s" in the URL will result in a search engine entry)
Paste the contents of the lower text area at the end of search.ini
Start Opera, hit Ctrl-F12 and go to the Search tab to see the new Search Engines
Note:
For some reason the search engines added this way don't sync through Opera Link unless you modify them and save them through the Opera interface. I'm looking into why that is.
Live a good life. If there are gods and they are just, then they will not care how devout you have been, but will welcome you based on the virtues you have lived by. If there are gods, but unjust, then you should not want to worship them. If there are no gods, then you will be gone, but will have lived a noble life that will live on in the memories of your loved ones. -- Marcus Aurelius, Meditations
