I love Konqueror, but certain sites do not feel the same way, gmail being one of them. One alternative is to have Konqueror identify itself as a different browser, say Firefox, but then you don’t show the world that you using Konqueror! There is another alternative though…

Under Tools -> Change Browser Identification -> Configure

On the right, click New and then enter this information:

When Browsing the following site:

Use the following identification
Safari 1.2.4 on Mac OSX

the real config will automatically appear. You can now reload gmail and select the standard view.
