It seems that installation may have done something to your former profile folder; you may have to hunt for it. According to the articles mentioned below, search engine details are in a file search.json.mozlz4. https://support.mozilla.org/en-US/kb/profiles-where-firefox-stores-user-data https://support.mozilla.org/en-US/kb/recovering-important-data-from-an-old-profile

tjn21, I copied over the file you suggested, but it made no difference. Also, I need to clarify my statement: the links are there, but the icons don't appear.

I don't use the address bar for searching. This article may help: https://support.mozilla.org/en-US/kb/search-firefox-address-bar From that article it seems the icons appear "when you start typing a search term ...."

tnj21, the search engines are there, but their icons arent. What does that mean?

You can rename/remove search.json.mozlz4 in the Firefox profile folder with Firefox closed to rebuild the search engines registry.

You can use the button on the "Help -> Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page.

• Help -> Troubleshooting Information -> Profile Folder/Directory:
  Windows: Open Folder; Linux: Open Directory; Mac: Show in Finder
• https://support.mozilla.org/en-US/kb/profiles-where-firefox-stores-user-data

Firefox will rebuild search.json.mozlz4 from the builtin search engines.

cor_el, thank you. That's one more thing off my to-do list. I renamed the file, and the icons for the alternate engine show again. Later, I'll go back and delete the old file. Again, many thanks. (Of course, we'll meet agin soon.)
