F11 is grayed out. How can I restore funtion is?

Until recently I could invoke (or output) mode full screen with the F11 key. Now, the F11 and F12 (for Firebug) are grayed out on the view menu and no longer work. I have not installed the new modules recently, so I presume that the cause is a recent day either Firefox or my OS. I'm using Firefox under Windows Professional 8.1 50.0.2 x 64.

Start Firefox in Safe Mode {web link} by pressing on the
(Mac = Options)
key and then from Firefox. A small dialog box should appear. Click start in Safe Mode (no refresh).

Is always the problem?

  • How can I restore my factory settings.i deleted my recovery files

    "How can I restore my laptop compaq presario cq57 windows computer factory settings 7", I deleted my recovery files.

    Hello

    If you have deleted the recovery Partition, you will not be able to create your own set of recovery disks, then you will need to order a replacement, set as described in my previous post.

    If you use these replacement disks to reinstall the operating system, they will also recreate the hard disk recovery Partition - this will allow to use the 'method f11' reinstall Windows if you wish.

    Kind regards

    Hi Jason,

    Can't you see it's not "SECURE" in the title bar for documents where the tools are grayed out? If you do, which would indicate that the document has been password protected and perhaps editing restrictions.

    Best,

  • If I accicentally delete a tab, how can I restore it?

    If I accidentally delete a tab, how can I restore it?

    I'm not sure what you mean by delete, but I'll mention a few things to get started:

    (1) If you accidentally closed a tab, but there is another tab open in the same window:

    • Make a right click No matter what tab > undo close tab

      • CTRL + SHIFT + t did the same thing
    • Use the menu list in the history of recently closed tabs to re - open the tab

    (2) If you accidentally close a tab, and that the entire window:

    • If you had another open window (Firefox did not close): allows you to re - open the window menu in the history of windows list recently closed
    • If Firefox shuts down: after starting Firefox, check the list of the menu in the history of recently closed windows. If none is listed, try to 'Restore previous Session' on the history menu and then check again.

    Create a new profile as a test to see if your profile is the source of the problem.

    See "create a profile":

    If the new profile works then you can transfer files from a profile already used in the new profile, but be careful not to copy files corrupted to avoid transporting more problems.
