Firefox renders webgl at 50%

[SkippyHub]

I believe firefox renders the xterm text as half the size compared to chrome which loads correctly.
firefox

chrome

anyone else have this issue?

using:
Terminal = require('xterm').Terminal;
FitAddon = require('xterm-addon-fit').FitAddon;
WebLinksAddon = require('xterm-addon-web-links').WebLinksAddon;
WebglAddon = require('xterm-addon-webgl').WebglAddon;
CanvasAddon = require('xterm-addon-canvas').CanvasAddon;

Cannot repro with xterm.js demo. Which xterm.js version and OS are you on? Is that from the demo? Plz also check, if your browser has some zoom setting active or not.
