Comment My report: 6 months without using Flash (Score 4, Interesting) 167
Some time ago, after the last round of Flash exploits, I de-installed it and resolved to live without it.
There are glitches: I can't get most video content, and Flash-only sites are inaccessible. However, this ended up being not a big issue.
One reason for this is that many YouTube videos play in HTML5 on Firefox. (If you find a video you can't play, try embedding it; this sometimes produces a workable version.)
Overall, the playback on HTML5 is better than Flash. There are fewer random slowdowns and stall-outs. On the downside, not every video is in HTML5.
The most amazing this is that browser crashes have dropped to near zero, either one or zero during this time. Most of what I thought was FF and Opera being buggy was in fact Flash being buggy.
There's not yet enough content switched to HTML5 from Flash to navigate everything, but during my 6 months without Flash, I've noticed that more firms are going away from the Flash-only navigation school of design.
YMMV. For me, life without Flash has been better, although I do miss out on some things.
