My computers primary hard drive semi failed and ceased to function as a primary operating system drive, so I purchased a new HDD to install my OS on as a main drive. However I was unable to import my Firefox bookmarks from my old version of Firefox, but i can still access the Firefox install folder on my old hard drive. However any attempt to load Firefox through the old directory does not yield any of my old bookmarks. Is there a way to recover those lost bookmarks using the old files from my previous OS?
