Disabling flash does not work with VLCTube

[Joschasa]

I can't use youtube with VLCTube and flash plugin disabled.

Error: For video playback either Adobe Flash Player or a browser with HTML5 compatibility is required. ("Für die Videowiedergabe ist entweder der Adobe Flash Player oder ein Browser mit HTML5-Kompatibilität erforderlich.")

Without VLCTube the HTML5 player loads just fine. With flash plugin enabled (but on "ask to activate") VLCTube works fine aswell.

Browser: Firefox 39 OS: Arch Linux

Same issue on Fedora 21. What is even more stupid, is that I have outdated Flash plugin that doesn't even load in Firefox AT ALL because Mozilla blocked it, but it still makes VLCTube work if I put it on "ask to activate" (and it of course never asks since it's blocked by Mozilla).

EDIT: Actually, it's even more bizarre, outdated Flash can load, but it can't be set to "Always Activate" and it's off by default on all pages and Firefox warns about it being outdated when there is request to load it. I was thrown off by the fact that YouTube NEVER asks for Flash to load when loading a video (just asked now on main page once).

Table of outdated Flash x VLCTube interaction:

VLCTube	Flash on "Ask to Activate"	Flash on "Never Activate"
VLCTube is ON	VLC player works correctly	Everything breaks (message about needing Flash or HTML5 is shown in place of the player and only control bar of VLC player is visible)
VLCTube is OFF	HTML5 player works correctly	HTML5 player works correctly

I have found this to be the case as well. If you uninstall Flash, VLCTube works, but then it always autoplays and in the console a

I think the solution is to uninstall Flash ~~and fix VLCTube to prevent YouTube from forcing autoplay~~.

Edit: So I found that the console message was coming from VLCTube, where is tries to nuke the HTML5 player. But, I think the real problem for the autoplay is on Firefox 40 browser the config options work. On Firefox 43 I can't set any config options, so it is probably default autoplay in VLCtube that was messing me up, and I can't seem to get it to show any checks or save any.

Edit 2: I deleted the VLCTube.db and when it was recreated setting config options now works, I guess it was a strange GM\FireFox file permission error, not VLCTube related.
