I've had it with Adobe Flash on Linux. While I give kudos to Adobe for releasing a 64-bit version of Flash on Linux before a 64-bit version on Windows or Mac, I have to say the implementation sucks. It's incredibly greedy for CPU and memory resources, and maintains a large footprint in the system even after all Flash videos have finished playing!
I noticed that VLC has a small footprint, plays Flash videos well, and accepts YouTube URLs as inputs for network streaming. So, would it be possible for it to replace Adobe Flash as a browser plug-in? (for Firefox mainly, though support for Epiphany, Konqueror, SeaMonkey, and/or Opera would be welcome.)
A 'clean' implementation would be a plug-in or extension that embeds VLC into the browser, with a whitelist/blacklist system for permitting/blocking Flash videos depending on the source, but at this point I'm so frustrated with Flash that I'd be happy with a one-click method that opens VLC as an external app and passes the URL from the browser to VLC to play.
You would have the gratitude of the multitude of Linux users who have given up on Adobe.
