Fixed addon not working with dynamically added video tags - such as when you open a YouTube video in the current tab instead of opening it in the new one. This is a big fix actually.

Pulled back the 'access your data on all sites' permission requirement, now it asks for these permissions only on supported sites.

1.1.1:
Sadly, version 1.1.0 was borked and had a stupid bug that caused the addon to simply not work

1.1.0:
Added:
- Support for Twitch VOD's
- Config for different styles of the time parameter in the URL (both YouTube and Twitch support both seconds-only and HMS) per site
Fixed:
- Worked around Firefox bug 753264 (https://bugzilla.mozilla.org/show_bug.cgi?id=753264) that causes the history clutter by manually removing excess history items
- Better icon rendering on HiDPI displays
