firefox extension question

Question

Browser extensions

To develop extensions, I use addon-sdk, and I'm interested in the following details:
1. Is it possible after running "cfx ​​run -p profile" to make a change in the code that will automatically load, otherwise I'm tired of restarting the browser every time (something like in chrome "Refresh (CTRL + R)").
2. How to properly debug firefox? Now I open the browser debugger to debug, is there a nicer way, for example the same as in chrome?
