TO on other Chromium Browsers ?

Yep, need to check them. Will do this after the next major release, it is anyway hugely rewritten so there is no sense to check with the current version. Meantime the  next major release  of TO have more priority then the Opera or Iron support. 

I do plan support the Opera actually.

But if for true i am not very exiting about this idea, it's hard enough already to support the Chromium and retest on all of the combinations of OSes and browsers.
