Videos will not work unless I have keep the cursor, or switch to full screen mode. This does not happen on Internet Explorer.

I've updated the flash player.

In past threads, users said that they managed to solve this problem in a variety of different ways, suggesting that there may be multiple causes:

  • Remove unwanted extensions
  • Clean malware
  • Disable hardware acceleration
  • Change to a different drive Flash (developer/debugger version)

In response to these first two, here is my procedure suggested to track down and cleaning of the bad modules. I know it seems long, but it's not so bad.

(1) open the Control Panel, uninstall a program. After the loading of the list, click on the column heading "installed on" to group infections, I mean additions by date. This can help the undisclosed items bundle smoker who snuck out with some software, you have agreed to install. Beware of everything that you don't recognize / remember, since malware often uses sounding names important or innocent to discourage you remove. Out as much garbage as possible here.

(2) open Firefox page modules using either:

  • CTRL + SHIFT + a
  • "3-bar" menu button (or tools) > Add-ons
  • in the Windows "Run" dialog box, type or paste
    firefox.exe "about:addons"

In the left column, click on Plugins. Set essential and unrecognized plugins 'never enable '.

In the left column, click Extensions. Then, in case of doubt, disable (or delete, if possible) not recognized and unwanted extensions.

Often, a link will appear above at least an extension disabled to restart Firefox. You can complete your work on the tab and click one of the links in the last step.

Any improvement?

(3) you can search the rest of problems with scanning/cleaning tools listed in our technical support article: Troubleshooting Firefox problems caused by malware. These scanners on request are free and take a long time to run. If they end quickly, especially if they require the payment you have a serious infection. I suggest the specialty forums listed in the article in this case.

Success?

  • In Photoshop CC 2015, when I switch to full screen mode (only F tap, not two) my panels often disappear (but not always) by themselves.  I exit full screen to retrieve them.

    I had this problem two major updates there is a CC of Photoshop.  The last update seemed to remedy, but with the last update major it is back.  I enter full screen often, as this is how I prefer to work and usually it works fine.  I know that the panels disappear if I press F twice, but I'm not in this mode, I'm only in the first full-screen mode.  They do not disappear immediately.  They disappear more often right after an action, for example when the action makes the Panel properties pop up, all other panels (layers, etc.) will disappear.  Sometimes press the tab brings back them, sometimes it just makes drop-down menus (file, editing, etc.) appear and disappear.  I can't be the only one with this problem, but I have not yet find a discussion on the subject.

    Someone has an idea what is the problem?

    I have an i7-4770 CPU and GPU Radeon R9 200 series running Windows 8.1

    Hi Mdentonetc,

    If this is the latest version of Photoshop and you do not have enough customize the tools Panel, then you can try resetting that default return Photoshop preferences.

    Steps to follow:

    To re-create the Photoshop preferences files, start the application while pressing Ctrl + Alt + Shift (Windows) or command + Option + shift (Mac OS). Then, click Yes to the message, "Delete the Adobe Photoshop settings file?"

    Lets us know if that helps.

    Hello

    Where it has been plugged in before?

    If you are using to connect via Wireless, then it might be that your wireless connection has a problem.

    ----------------------------

    Wi - Fi in general.

    These steps and tell us where is the breaking point.

    Check the Device Manager for the wireless card valid entry.

    http://www.ezlan.NET/Win7/net_dm.jpg

    If there is no valid entry, remove any entry from fake and re - install the drivers for the wireless card.

    Check network connections to make sure that you have a network icon/entry wireless connection, and that the properties of the icon (right-click on the icon) are correctly configured with the TCP/IPv4 protocol in the properties of network connections.

    http://www.ezlan.NET/Win7/net_connection_tcp.jpg

    ------------------

    The wireless card drivers much also install utility wireless of the seller.

    Make sure that if there are teas from Wireless Utility of seller does not work with the native Windows wireless utility (Service WLAN).

    ----------------

    Make sure you firewall No. preventing / blocks wireless components to join the network.

    Some 3rd party software firewall continue to block the same aspects it traffic Local, they are turned Off (disabled). If possible set up the firewall correctly, otherwise totally uninstall and get rid of its remaining processes that permit the own local network traffic flow.

    If the 3rd party software is uninstalled, or disables, make sure Windows native firewall is active .

    party like Hello and NetMagic 3rd network managers can block local traffic too.

    ---------------------------

    Stack TCP/IP work should look like.

    Right-click on the wireless network connection card, select status, details and see if she got an IP address and the rest of the settings.

    http://www.ezlan.NET/Win7/status-NIC.jpg

    Description is the data of the card making.

    The physical address is MAC of the card number.

    The xx must be a number between 0 and 255 (all xx even number).

    YY should be between 0 and 255

    ZZ should be between 0 and 255 (zz all the same number.)

    The date of the lease must be valid at the present time.

    * Note 1. IP that starts with 169.xxx.xxx.xxx isn't valid functional IP.

    * Note 2. There could be an IPv6 entries too. However, they are not functional for Internet or LAN traffic. They are necessary for Win 7 homegroup special configuration.

    ---------------------------------------------------

    A message in the small window that says connected wireless doesn't means that you are really a valid functional connection.

    Above everything is OK, you must be able to connect to the router.

    Connection to the router means that you can enter the IP of the router base in an address bar in one go, being able to connect and configure the router menus see.

    If it doesn't connect to the router, journal newspaper from any computer that can connect to the router wirelessly with a wire, disable wireless security, make sure that the wireless SSID broadcast is enabled and try to connect with no. wireless security.

    Enable security wireless after you eat to make a functional connection.
