Works great, but for one critical flaw: One can define multiple commands, but only one displays in the toolbar :-(

Does the job. But if you pin a batch file it does not parse it correctly. In my example it skipped any more advanced programming arguments, and went straight to a timeout command within the batch. Compiling as an executable fixed this but I gotta -1 for this. Ill happily submit my batch code.

Also minus 1 for the client, connection check at the beginning, and vagueness surrounding this client. Is it always running as a service? Does it only open with Firefox?

Just want to pin a simple batch file! FF57 in case that matters.

With Firefox ESR v52.5.0 (64-bit) the right-click on the toolbar icon does not bring up a context menu to select the external application. You have to go to the Add-ons page to change this which is rather laborious. This is with the latest version 0.2.7 which claims to have fixed an ESR v52 bug, so looks like there are more.

click the add application button and nothing happens.
The chrome addon works well.

always told me select a placement for application , can not work. 55.0a1
