Not ones of any value, I've found. If they still insist on FLASH they don't get my business. Monst of what I've seen that require Flash are ads. When I run across a major website that still requires Flash, I write to the CEO of the sponsoring company, not the IT guy building the site, he's too stupid to write to, telling him how his IT/webmaster is giving his company a bad reputation by forcing potential customers to load a malware magnet on their computers to buy his products or use his service. I'm quite specific about it and include links to articles on the failings of Flash and the constant number of zero day vulnerabilities and exploits. I also demonstrate there's a reasonable substitute that exists in the HTML5 standard code. I then ask "Are you in the business of selling your products/services, or in the business of supporting and advancing Adobe's bug filled product?" You'd be surprised how often that gets results and how quickly!
But is HTML5 really all that helpful? In the past few months, I have found that attempting to view vids running Firefox on the YouTube site after just a few views the browser comes to a complete halt and I must necessarily halt the process and restart it to view the rest of the video I wish to access.
Granted, that may be a personal computer problem with the setup I have here, but considering how careful I am about allowing upgrades to the system and only connecting to Stable repos, I am for the moment quite severely concerned about why this is occurring.
I am concerned that the HTML5 standard is beginning to cause more problems than solved with the elimination of the Flash standard.
