Only gripe I have with Opera is poor compatibility with certain (many) sites. Apart from that its good.
People saying Opera is the most compatible browser is a classic example of
"If you say a lie enough times it becomes the truth"
I don't have data to make the case, i can only say it depends on the websites you visit, so its really comes down to if it fit your personal usage, in your case, its obviously a no
But,Im not sure if opera's compatibility is much worst than firefox or safari. I can only say that opera has very good w3c standard compatibility, at least as good as any other browser.
my friend, you really need to try it out before making judgment, and thats all this post is about.The same things I said about Firefox go for Opera as well.
The interface is made in Cocoa, not XUL. Uses the system-wide dictionary. Can access the Services menu. Uses Keychain. Updates come through Software Update. Has access to the text-to-speech service. Drag and drop produces a ghost image of what your dragging instead of an awful looking box. I can drag bookmarks along the bookmarks bar and I can drag them off. The web inspector in Safari 3 rocks.
part of the statement u made is no accurate:
Opera has ghost image when u drag images
opera allows you to access service menu
both firefox and opera allow you to drag re-arrange bookmarks along bookmark toolbar
and both opera and firefox allow you to remember multiple passwors/usernames for same websites, imagine when u have 2,3,4,5 gmail accounts,
firefox 3 is completely written in cocoa.
