By clicking on "Add to Firefox" button in the web page for TabGroups Manager (https://addons.mozilla.org/en-us/firefox/addon/tabgroups-manager/), and restarting my computer, I found an extra bar for "Tabs" added on my Firefox 21 browser window. That bar does not provide at all what I was looking for. In fact, I cannot figure out at all what it is supposed to facilitate. Now I cannot figure out a way to get rid of it. How do I accomplish that?
I was hoping, by the way, to have, if I easily could, an additional bar identical to my current Tabs bar. Is there a way to obtain it?
Help, my PC with Windows 10 won't shut down properly
Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
