From time to time I'm forced into switching for different browser instead of my favorite – Opera. Frequent message saying “You browser is currently not supported” is very annoying. This are most common on Wiki and Docs,but Gmail is Opera crippled as well.
And each time I see it, I, myself as a developer, understand reasons behind it. Yes it is FF that has all set of plug-ins and in fact became a developer tool rather than a browser. But this is still not a reason to provide less support to the best browser available. I'm not here to argue why I've stated Opera the best, yes I know that it has a lot of problems (I've mentioned that I'm a developer :)). But the painful aspect is that I can't notice the movement.
Guys, I really like products of your company, but it is so disappointing when you can't get all from products you like on the browser that you favor so much!
