Patches, patches and some bugs

As I have done most of work on Specta Player on my Chromebook I wasn't aware of a few issues appearing in Firefox and Edge. I strongly apologise for that and I'm happy to tell you that Firefox is back on the track with the last known bug being investigated on other repositories (updates in #2). Edge sadly stays visually broken but it is usable if it needs to (updates in #3). I'm working on those issues very hard to make sure they are resolved as fast as possible.
