While normal user could still stay with the latest stable version of Firefox 3.0.11, since the RC version is intended for developers and members of the testing community.

Product analyst Lawrence Eng says, "With Opera Unite, everyday non-technical users can serve and share content and services directly from their own computers in the form of intuitive applications."

A media application has come with Opera Unite as a demostration. Using this Jukebox tool, all "united" friends will select their favorite songs, and combine together to form a virture online radio.

And Lawrence Eng believes that "That’s just the tiniest tip of the iceberg—the potential for what can be done is much larger. The key to Opera Unite is that it enables a whole new class of social software on the Web, applications that benefit from two or more people being online at the same time. And, with Opera Unite, these people can all connect directly without needing middlemen who control third-party servers."

The thing is Firefox treat feed from WordPress a little bit different from other browsers, ie, with the same feed address, I got full content in IE.

After a search, I found the solution and technique explanation, see how to force Firefox to display your full feeds.

You needs some knowladge about WordPress and coding to understand, but it’s not necessary to learn why it’s happening, you can just follow the steps in the article and have it done.

I suppose most users subscribe feed using Clients such as Google Reader, but not the browser itself. The trick may be more valuable for bloggers who want to control there feeds perfectly.

According to the official site, Opera 4.2 running faster than the old version, thanks to the increase of server park in United States. And this leading mobile browser product has been the first alternative on Android powered phone.

To backup default profile

Run the program, you will see only one profile named User Data in the Google Chrome Profiles window. To backup, just click Run Wizard! button to bring out the backup wizard dialog. Select the Backup radio button and click next, then select Backup default profile radio button and click next. Click Browse button to specify a location you want to put the backup file (with .gcb extension) and click Finish button. Wait until you see the message "Saved to …", you now have had the default Google Chrome profile saved successfully.

To backup user created profile

Still click the Run Wizard! button, but this time select "Select a profile to backup" when you are asked to choose which profile to save. I believe you know what to do next

To add a new profile

In the program’s main window, click Profile button and choose New Profile, input a Profile Name you like, for example logger, then press OK button. Now you got a new Google Chrome profile in c:logger folder, and a shortcut to launch it in your desktop.

To remove a profile

Simply right click the profile name in the list, and select Delete. But by doing this, neither the profile folder nor the shortcut is actually deleted from your system. What the program did is removing the relevant entry in one of its own setting files – profiles.dat. However, you can delete the profile folder and shortcut manually if you want.

To restore a profile(or copy one profile’s setting to another)

Run the wizard, and select Restore, Browse to the .gcb file you backed up and click Next, choose which profile you want to restore and click Next, Restore.

Notes

When I click the Preferences of this program, it crashed. I tried several time, and got the same result, so I don’t know what settings it have.

You can manually create a shortcut with switch -user-data-dir="logger", this will create a folder logger in root dir of C drive if it does not exist.

Another useful switch is –incognito, which lets you start Google Chrome in private mode (incognito window).

We know that Firefox comes with a built-in Profile Manager to manage multi user profile, it’s good for Google Chrome to have this feature in the future release.

Different profiles can hold different bookmarks, cookies and other user data, so it’s good for people who need to separate working and life.

It’s a shock for me that Google takes the beta label away this quick (even Gmail is still in beta). Is it a sign that Google will put more focus on browser market and maybe more actions based on Google Chrome?

Anyway, without a extension system and cross platform support, Google Chrome can not be users’ first choice of browser. It can’t beat Firefox or IE in short time.

Download Google Chrome [via Official Google Blog]

For example, there is a plain text of a URL, you can just highlight the URL, and drag it to the current tab to open it in current tab, or drag it to the blank area in tab bar to open it in a new tab.

Same actions can be done on image, try it.
