Firefox Extension : Auto Full Screen and Support Dual Monitor on start up on Firefox v50.x or latter
I use Firefox as our default browser to show our business intelligence dashboard in our company. We facing some issue that our dashboard need to be automatically full screen at startup instead of press F11 every our mini PC started. We use the latest version of Firefox which is version 56.0.2. After do some research, we've found that Firefox not longer stores the Maximized and Full Screen mode setting in xulstore.json ("sizemode":"normal"), so it isn't possible to start Firefox in Full Screen mode without using an extension.
Our others issue is our dashboard will use multiple monitor to show more than one tab. Every tab will show one dashboard. Every Firefox started, we want every monitor showing one tab in full screen mode using our homepage url that we define in preferences-home page.
So, how we can write our self-written extension without using any exist extension like mFull? I've tried to find similar article on internet about Full Screen and Multiple Monitor extension on Firefox but I'm not sure I found what I looking for.

Mozilla is 2 days away , Nov 14th from launching Firefox 57 Quantum https://www.mozilla.org/en-US/firefox/quantum/ Note : Legacy Extensions will be disabled and or removed. and https://www.theinquirer.net/inquirer/news/3020724/firefox-quantum-everything-you-need-to-know-ahead-of-next-weeks-release
It is smoking fast.
So with that being said is there much point in doing anything for your 56.0.2 version when the whole look of Firefox is changing. As 57 gets out more info will trickle out as to how to make changes in the guts of it.
To submit suggestions for new or changed features, may I suggest:

Oh..........all Extensions are now coded completely different than what they have been so if your writing code it best be compatible to 57 and beyond.

Now forgot.... If want a earlier browser can go pick one https://ftp.mozilla.org/pub/firefox/releases/ Or you can move to the Extended Release Version 52.4.1 which only gets secuity updates, can run legacy extensions with that and should beable to play in the guts to do what you want. https://www.mozilla.org/en-US/firefox/organizations/
Please let us know if this solved your issue or if need further assistance.

@Pkshadow, after reading your answer we can conclude that it will be better if we wrote code using Web Extension API. is't right?
Thus, for this issue we consider to develop using Web Extension on FF 57 or latter. Unfortunately, I'm not sure have completely read all Web Extension API, but I'm not found the solution of our problem regardless make FF fully screen automatically at start up and support multiple monitor. Is there any references for our issue? Or is it web extension not fully supported for this features then I need to submit suggestion for new features? Any Idea?
I waiting for any good news. Thanks

After do some experiment, I've successfully create addons using web extension to set FF fullscreen at start up using [API] . However, I'm still looking for somehow to start a new window for every monitor in multiple monitor mode. Any idea?
