i am too not sure...i can only compare the results in ff and opera..in opera i dont have the sun java starting...
so i only want to use 1 browser
Why? Unless you're hurting for computer power, having two browsers open or loading Firefox when needed is no big deal.
btw..how handle other users this issue with opera? do they use really 2 browsers?
I certainly do. Three sometimes, because maybe I just feel like using SeaMonkey sometimes. Opera is my favorite and has features no other browser has and it works fine with the vast majority of Web sites. If I hit one that doesn't (and one of my regulars does have problems with Opera), I use Firefox, which is likely to work. If it's an Internet Explorer only site, well, we're all in trouble then. But fortunately those sites are becoming fewer.
