I have been testing all the four major browsers. But with the recent beta I think opera has won my vote.
I wanted a browser that would save my bookmarks across computers.
Opera went ahead and did one better, they made it even possible to sync your bookmarks to your mobile. And opera has one of the best mobile browsers around.
So now if find anything on mobile or PC I just bookmark it and it will be available on the later without any effort on my part.
You will need to download the latest opera browser beta for PC and the latest opera mini beta and create an account which is really easy. Once you create an account and give your username and password every 10 minutes it automatically syncs the changes in your bookmarks. You could always stop the syncing if you don't want it.
There is also a features called wand which save the username and passwords for website logins. So if you are tired of logging into your mail or other sites with logins. Once you save the username and password by going to the site one time. From then on you just hit ctrl+Enter and you will be logged in. The best part is you could have multiple logins for a single site. If you have multiple logins it will give you an option to select which one you want to get logged in with. All in all a great feature.
How to Save or Export Wand Passwords from Opera
Here is the trick when you upgrade or move to a new computer if you want your wand passwords also then just type "C:Documents and SettingsUser 4Application Data" look in this folder for opera and in the opera folder for profiles and then copy the file "wand.dat" and it has all your logins. Don't worry even if someone gets the file they can't read it because its encrypted. Copy it to a safe place and once you upgrade or move your PC just put the file back into the same place and all your logins work like before.
