@KenW holy crap, who knew .... very cool!
That is some heavy duty Firefox Foo .... something that might very well lead me into temptation and eventual disaster 🙂 I changed it to 200 which I like more than the default.
I found another feature of Firefox - you can save groups of tabs. So what I did was to create a bookmark of all individual printer IP's and all associated camera ip's so it is very easy to open up a new Firefox window and open all 3D printing related tabs at once. So now all I have to do is click on the bookmark and tell it to open all tabs. As a bonus, it keeps the tabs in order so all the camera feeds ,which show no indication on the tab as to which camera they belong to, are opened as an ordered group. DWC for printer one, printer one camera, DWC for printer two, printer two camera and so on.
Thanks!
