Last week, I had to re-installed OS X 10.8.5 (Mountain Lion) on my iMac because of lightening bolt surge. And, after doing so, I then had to re-install the Waterfox browser app. to gain better access to my email account (because the old version of Safari that came with the vintage OS re-installation is no longer viable)

My questions are: 1. Do my former bookmarks (or the Waterfox profile that they were stored in) still exist somewhere? and 2. Is it possible to retrieve them to replace (and/or add them to) the new profiled bookmarks created with the updated Waterfox app.?

I've already tried following some of the suggested help from the forum questions that I read here, but have been disheartened because no backups for my years of bookmarking seem to exist. Sadly, I never knew that there was a way to back up bookmarks prior to this recent investigation.
