Display the web address in Firefox's tab tooltip

Mozilla a while ago decided that it would be a good idea to remove the title bar from the Firefox browser and rely solely on the tab to display the title of the site. While that is working okay for sites with short titles, it does not work well for sites that use longer titles as they do not display fully in the tab. You can hover the mouse over the tab to display the full tab title.

Related to that is something that may not be an issue for many web users. All tab driven browsers display only the web address of the website that is currently displayed in the active tab in the browser. If you want to display the url of a site that is open in another tab, you have to switch to that tab first to do so.

Tab Tooltip is a lightweight extension for the Firefox web browser that adds tooltip information to each open tab in Firefox to display the web address of the website that is open in that tab directly on mouse hover.

You are probably asking yourself why you would want to install such an extension. There are a couple of scenarios where this may come in handy.

  • A website that you open in multiple tabs regularly displays the same page title on all tabs. If that is the case, you can't really differentiate between tabs so that it becomes hard to pick the right tab to go to.
  • Some titles get shortened when displayed in tabs so that it becomes impossible to determine the site that is open in those tabs. The shortened title for the popular eBay website for insstance reads "Electronics, Cars, Fashion, Collectibles, C...". While you can sometimes use the favicon to identify a site, more often than not you may not be able to do so.

The extension adds a second line to the tooltip that displays the full url of the site. To display it, simply hover over any tab in the Firefox web browser.

    I prefer the older format with tabs below the address bar. This provides for a title bar with the tab information displayed in the title bar.

    Easy enough to tweak Firefox to do this:

    1. Go to about:config
    2. Search for “browser.tabs.onTop”
    3. Change from “true” to “false”.
    4. Restart Firefox.

    Just installed it. Great. I love these little codes that make life easier. This is well thought, 2KB of pure brains. I think many users like these add-ons also which are darn useful.
