like i already wrote in another thread - i found bibitnow as a possible alternative to get info from your browser to jabref.
Maybe this could be an (even better) alternative ? I have looked into it a little (still using zotero as main literature manager) - but not in a real user case.
It seems available not for firefox only - so maybe you guys can “collaborate” with the extensions developers to make it work with jabref easily - and maybe make jabfox obsolete with that (not meaning it is not needed/shitty or something - but you simply don’t have to reinvent the wheel to have a working solution for several os and browsers by integrating a working solution - which you don’t have to spent time on yourself.).
