Is there a dom inspector flag for Fennec?

I've got Dom Inspector installed on Fennec on my desktop, and sometimes the cmd+shift+i hotkey works and someti开发者_JS百科mes it doesn't (or maybe I'm forgetting it?).. so I"m wondering if anyone knows if there is a command line flag that I can use to open the dom inspector when Fennec opens?

Using the same argument as works with Firefox works for me:

fennec -inspector <URL>
