Adobe Flash on Opera/Linux has always been quirky , crashy and all-round unreliable for me in the past. So, I use Opera as my pure-HTML+javascript browser, with ALL plugins, sound, animation, and Java plugins turned off in Global preferences. Going off-topic [Opera praise]: These settings instantly turn Opera into the most stable and shockingly scalable 'Research and reference' browser I've used. I only use Firefox3.5.x solely for web-dev, Google Apps, heavy-JS Web 2.0 apps, and Flash-enabled sites of course (with Flashblock as first-line-defence).
