Accessing the places database directly would be great of course
The problem is not accessing the DB (I manage to make that work, see the previous link). I was even able to execute the UPDATE… but there is a hash to prevent unwanted modifications. I found some python code that should calculate the hash, but Firefox did not like it… or I missed some detail (encoding maybe?). Personally, the workflow I achieved with that script is good-enough for me, but it’s far from ideal.
The other usual approach to scripting in the browser is ViolentMonkey (or TamperMonkey, or others), much better for big scripts. The downside is that (AFAIK) you need to inject in every page all the scripts you want to be able to execute and (again, AFAIK) there is no way to run them as easy as “Control+L” (focus navbar) > Type keyword… which I have now so ingrained in my brain :D.
