I just stumbled accross a possibly undocumented feature of the Firefox Browser's handling of Tabs for displayed pages.
I recorded a brief video for that.
- Collapse and Expand Tabs (webm-formatted screencast)
Snapshot before "collapsing":
If you click and hold on the Tab for an open web page, then drag that Tab so that the cursor is at the far left edge of the browser, with the cursor over the "site-specific icon", then release the mouse, the Tab will "collapse" to display only that icon!!!
Snapshot of tabs "collapsed":
To reverse the process, simply click and hold on any of those "collapsed" tabs, then drag until the cursor is in "unused space" on that Tab bar, then release the cursor, the Tab will be restored to its "Expanded" view with its Page Title visible.
