Titlebar Tweaks is a Firefox plugin which let user change the title bar for different format. For example, you can set the title to “My browser”.
User can change the title to any text they want, or they can change the format of the title bar. For example, the default format is “Webpage title – Browser Name”. But, user can change the title format to display either webpage title only or browser name only, or display both, with different order.
After download the plugin, go to your Firefox->Tools->Add-ons and choose Titlebar Tweaks. After that, you can start changing your Firefox titlebar.
Install this plugin in your office computer. You can then change the title of Firefox so that your boss/friends don’t know the page title. But, if your office computer comes with any logging aplications, your admin still can find out your internet activities.
This doesn’t work in FF3.
