Many people have asked for the ability to move their tabs to the side in Google Chrome. This is a feature that first took off in Firefox, and fortunately the Chromium team has graciously put them into the early builds. Now, if you’re using Chrome 6 in the form of the development or canary builds, you can have sidebar tabs as well.
The first thing you need to do is add “–enable-sidebar-tabs” to your Chrome shortcut like this.
To revert to regular tabs, right click on an open tab and uncheck the Use side tabs option.
I’m not sure what to think about sidebar tabs – I’ve never used them, so I am accustomed to using regular tabs on the top. I think the feature also need a bit of UI polish as well, but if you’re using Firefox just for the sidebar tabs, you might want to grab yourself the development build of Chrome and give it a shot.
