Nice plugin, works well, but…

I like this plugin but it would be much better if I could test each video format with the same browser, via some kind of runtime switch. As it is, using my standard Vivaldi, I get the WEBM version because my browser will handle it; and I have to find a non-WEBM-capable Android or Linux browser to try to test the other formats on my live server. This does not add to productivity.
