Got blur working on ff88+

[PoSayDone]

Hi! I've got theme working with blur.
I've imported window-transparencies.css to userChrome.css from this theme and got blur working properly!

Works great for me in AwesomeWM and KDE.

I've isolated the rule that enables tranparency down to this:

#navigator-toolbox {
	background: var(--bf-navbar-bg) !important;
	border: none !important;
}

I switched --bct-w-nav-bg with --bf-navbar-bg so as to use the active blurredfox theme.

It looks like the url bar color can somewhat be recovered by removing all the -moz-lwtheme-darktext and:-moz-lwtheme-brighttext tags from parts/urlbar.css, and then removing all the resulting duplicate rules. It's not the same color as what's in the original screenshots, but the url bar is definitely slightly different.

I'm still missing blur on the recommended url thing that pops up when you click the url bar. If anyone has a fix for that I would be ecstatic.
