To be honest, why expect application support at all for these features? These things should be the domain of the OS, not applications.
This answer is somewhat foreshortened over my previous attempt - for some reason slashdot lost my previous draft when I logged in.
At least with Chrome, I could always use it on Linux for just those rare occasions needed.
I use Chrome when I have to (one of my client's software only works in Chrome and Chrome's development tools are pretty cool). Otherwise, I use Seamonkey, as I can find everything I need. I'll use Firefox when a web site refuses to serve Seamonkey (looking at you Slack), but otherwise the lack of menu items to find things like "Open file", or "open new window" makes it a bit annoying for my main browser. Ya, probably this is me not being used to the Firefox way of doing things, but anyway.
The Tao is like a glob pattern: used but never used up. It is like the extern void: filled with infinite possibilities.
