Share bookmarks locally between different profiles
I have for now a work flow where I share my bookmarks between different firefox profiles, without any acces to web/net/cloud/whatever..., all is local to my computer. This works well with an old firefox version. But, because there is a but. I'm blocked in this situation. My firefox version is 60.9.0esr. I can't go higher because starting with firefox version 62, there where changes that prevent concurrent access to sqlite databases.
I did some search in addons to try to find an alternative, without success. I also already done a research in previous support questions, without success too.
So, maybe someone have an idea or suggestion, to help me achieve that, or something similar, with newer firefox version. I need to upgrade to something more up to date.
Thanks in advance, K.
