First, let me say that I use Linkman as my all purpose bookmark keeper, and have it working excellently with multiple browsers at one time. Firefox Quantum ESR, Chrome, Pale Moon Waterfox, Opera and many others can all be used with Linkman. There is little or no architectural variance. You get the Linkman button in the toolbar, and then add (using port 81, so as not to clash with Skype) and edit bookmarks either from the toolbar or from their drop basket, a frog which floats in the moat. All excellent there, and highly recommended. And I do lots of jiggling to keep information there, based on keyword linkage.
My normal bookmarks, for super-quick access, work on the bookmark bar, about 20 folders - health, biz, puter, scripture, and lots of easy access stuff there. And I like to drop new stuff in. I do not have to change the structure, e.g. adding folders, except every blue moon.
This bookmark bar can be replicated on Pale Moon, and any other browser that will import the file.
Right now I simply keep Firefox Quantum as my master, and switch back there when I want to add.
My goal is to be able to add to maybe 3 or more browsers that all have the same bookmark structure. And then every once in a while, maybe weekly, put all the additions together. If a subfolder was added in one browser, and a different subfolder was added in another browser, I would like both to be in the new master structure. And I am not worried about deletions, changes of names and stuff like that. I would be aware than changing names would create duplicates.
Is this pseudo-synchronization idea feasible? How?
Your thoughts welcome!
