the solution to the issue of synchronization on multiple computers

Hello.

(chrome)
on one computer is stylebot. I ordered the style for all visited links red (on one site, this is still enough)
this is done so that I can see I came to this page or not.

How to make sync between multiple computers?
*if synchronize history is standard, links are still not highlighted.
*it's possible that different computers will work simultaneously, i.e., synchronization should happen very often (maybe once a minute)

1. the words "leg" to verify that you are not a bot
2. variant implementation of the decision
3. the price for your decision
4. can arrange MEM, then write whether or not the SLR
