Need to export bookmarks from Firefox old version 68
I need to export a collection of Firefox bookmarks from an old Android tablet. The latest version of Firefox that will run on this system is 68.0.2, which apparently did not have the ability to sync bookmarks or any option in the settings to export bookmarks. I would be happy if I could get the bookmarks in an HTML file or a plain text file. Or perhaps if I knew the directory in Android where Firefox stores the bookmarks, then I could copy it to a desktop computer.
This tablet will only run Android version 4.4.2. If I could find a way to view the support forums from a date when version 68 was still supported, I am sure I could find the answer myself.
Thanks very much! Lloyd
