I'm sorry, this is not really an answer to your question, but I have some thoughts. I believe in regularly clearing the history for my browsers because it is stored in the computer's RAM (memory). When that memory gets too full with that history, plus other things, it affects the functioning of the computer. I regularly restart my computer every week or so and I also clear the browser history every couple of weeks. I have little need to save those historys. If I want to revisit a site, it's saved as a bookmark. Just some things to consider.
