I seriously doubt you'll get an opposing opinion when it comes to dumping that beast Flash for HTML5, the Thoroughly Modern Millie of the interwebs be they a series of tubes or made of cats.

There's nothing ridiculous about maintaining a secure browser.
"but there are also many browsers to choose from."
I rode the browser merry go round until The Merry Go Round Broke Down (the Loony Tunes theme) and landed me on Firefox, a SECURE browser.
"A few versions back firefox blocked a bunch of useful plugins"
And soon regretted authoring Fartfox when Mozzarella was swamped with complaints. Only one is perfect and perfection is inscrutable.
"Those buttons are supposed to be links to useful URLs, and that could be accomplished with a simple HTML table and forget about the annoyances, overhead, and definite risks of scripts and flash if the message board software allows a direct approach like that."
BINGO. The whole idea behind starting this thread was not so much to start discussion, but more to attract the attention of the boffins that run this site. Flash is dead, only two of the sites I use forgot to bury it, and after a recent update caused it to act up the other site buried the stinking corpse.
