After resetting Firefox, LCD screen has lost its sharpness - as there are some missing pixels - WHY?

I have a PC running Windows 7 Ultimate. Lately when I'm in Firefox (running the most recent version), if I try to open more than one tab, Firefox slows down and I get the message "Mozilla Firefox does not. in a few seconds, regardless of site I try to open in the new tab opens; Firefox just seems to be morose. Finally, I tried to reset Firefox. After I did the reset, I noticed that the images on my screen (Acer LCD S200hl) appear to be less clear, even the wallpaper. As I type this, there seems to be holes in the image on the screen, as if the pixels are missing. Some letters look as if they are not completely filled. The only change is that I have reset Firefox.
Any help will be appreciated.

Where there is an incompatibility between Firefox and your graphics driver, try to disable the use of Firefox hardware acceleration. You could have done this once before, but of course, reset turns it back.

the button Firefox orange (or the Tools menu) > Options > advanced

In the mini ' General' tab, uncheck the box for "use hardware acceleration when available.

It will take effect after you exit and then restart Firefox. Any difference?

  • Windows cannot connect to the printer. The name of the printer has been correctly entered, or the specified printer has lost its connection to the server.

    A Windows Server 2003 Standard Edition SP2 32-bit computer is a field, the file and print server.

    A computer on the domain is a machine of Windows 7 Ultimate 64 - bit with HP DesignJet 500 24 printer connected via USB.  The printer is running the latest firmware.  The PC is running the latest 64-bit drivers with no problems to the host machine printing.  The host also has the latest drivers 32-bit (x 86) installed by downloading by other computers on the network.  The printer is configured to share with the share name of HPDJ500.

    Now, on a machine Windows XP Pro SP3 32 bit on the field, I'm trying to connect to the shared printer.  Add a printer > click Next in the wizard of > check "a network printer or a printer attached to another computer" and then click Next > click on "Find a printer in the directory", then click Next > click Find now > HPDJ500 in the list below (the XP machine can see the shared printer on the Windows 7 computer!) and click OK.  At this point, I get an error that says: "Windows cannot connect to the printer.  The name of the printer has been correctly entered, or the specified printer has lost its connection to the server.  For more information, click Help. »

    Alternatively, if I right-click on the HPDJ500 printer listed, then click on connect, I get the same error message but I also see a separate window that says "Connecting to HPDJ500 on H2.ws.net" with the lively projector.  This window also disappears as soon as I clear the error message.

    Please note that this printer worked perfectly as a printer shared, hosted on a machine XP 32 bit on the field.  It works perfectly for the new Windows 7 64-bit machine, but we cannot connect from anywhere else on the network (including the server which translates the same exact error message).  On the server, I also preinstalled drivers thinking there was a problem with a 32-bit computer, trying to grasp the correct drivers from the host 64-bit Windows 7, but that doesn't change anything.

    How connect to this printer?

    Try using the path UNC path of the printer in the Add Printer Wizard.

    Add a printer > network printer > connection to this printer ((deuxieme point)

    Click next to browse (leave blank, the name field) or type the UNC path of the printer (i.e. \\Computername\Printername) path

  • When sharing my project there are some clips that show a red screen with a camera saying error. How can I solve these clips if I can share the project correctly?

    When sharing my project there are some clips that show a red screen with a camera saying error. How can I solve these clips if I can share the project correctly?

    This happens usually when the import process was not completed. If you have the original camera card - or a copy of the computer of the map - you can probably use the re-import command (on the file menu) to fix things. In addition, it is possible that the original media is imported, but this transcoding was not. If you have chosen to optimise upon import, try to select clips in the browser and transcoding to optimized.

    I have a hard drive. At least two partitions. C: 74.7 GB with 63.3 freespace

    Right-click on the desktop and choose screen resolution. Assuming that
    you have a LCD monitor, set the resolution on what the manufacturer

  • Photosmart 7520: Photosmart 7520 has lost its wireless connection

    Our photosmart 7520 used to print beautifully two laptops, but today it stopped printing at all and seems to have lost its connection to the internet.

    I tried to remove it from my system preferences, to reset, and when I tried to add it, it was no longer on the list of available printers.

    Hello @cornylouise!

    Thanks for posting on the HP Forums!

    I would be happy to provide you with assistance on the Photosmart 7520 and the problem of communication between 2 laptops.  If the printer is no longer being found by computers, then you can by looking at a slight problem of Wi - Fi.  The first thing I would suggest is the cycle of power cables to the printer and the router by unplugging the power for 20 seconds.  Once the devices back on then see if you can add the printer to laptop computers.

    If you are unable to find the printer then I suggest to restore the default settings of network on the printer and it reconnect to the wireless network.

    To restore the default settings of the network printer:

    1. To press the Wi - Fi icon at the top of the touch screen to printer
    2. Tap Settings
    3. Tap on restore default network settings and confirm

    To run the Wireless Setup Wizard:

    1. Icon press the Wi - Fi at the top left of the screen touchscreen printer
    2. Tap Settings
    3. Press wireless configuration wizard
    4. Select your network
    5. Enter the password and confirm it
    6. Check if the computer can find the printer again

    If please, after back and let me know how it goes!

  • with the help of your friends desktop PC running XP has LOST ITS (out of nowhere) unable to recover. sound in the control panel is grayed out. so is audio; "no audio currency found!

    IE and Firefox running.

    Search engines are not the problem. I don't think so. Has also lost its icon in the systray.

    I checked the connections. I have a set of small peripheral speakers: they get power but no audio.

    Try reinstalling the Audio/software drivers from the manufacturers Web site.

  • Why my Kobo Glo has lost its permission to Adobe?

    I continue to post this question and it is not displayed on the forum, so here's one more time...

    My new Glo Kobo worked justfine with ADE and showed my authorization under account.  today I signed my Kobo account and re-setup of my camera, but now the Glo tells me that I am not connected to Adobe approval, and even though Windows recognizes the device ADE is no longer is grateful.  ADE is still recognizing my older Kobo wifi.  How to retrieve my authorization to Adobe for my Glo?

    SUCCESS AT LAST! But be careful.  And the problem is Kobo, I think.

    This time, before you do a factory reset or a reset, I uninstalled the Kobo Desktop of my computer application.  It had been earlier, on my computer from my old installation of Kobo Wifi and when I first set up my new Glo, the installation process caused Kobo website to download and install a copy on top of the old copy (same version as it turns out) Kobo desktop on my computer.  But the installation was not completely 'clean', I realized this time when the installation and configuration of the process AFTER uninstalling the previous one, has produced a few screens I had not seen before in the impure installation...

    This time, after you have uninstalled the software my computer Kobo, performed a rest of factory on the Glo and I then in the process of re-configuration.  It took a little longer than the first time, but once it ended, FINALLY Adobe Digital Editions the Glo has recognized and asked me if I wanted to allow it (Yes!).  After authorization, then I could copy all my files epub DRM of ADE in the Glo, and I checked that I can now read all.  Everything seems to be.  Some relief after the anger and frustration of the past 24 hours.

    Considering pain Kobo Desktop gave me (and the stuff's done horrible it to my app iPod content and mix up my shelves iPod with my Glo shelves without my inviting to), I decided that I will never use the Kobo Desktop again.  Later, when I buy something (good selection IMO) Kobo ebook site, I'll just download the DRM epub files, load them into ADE and ADE to transfer the contents of the Glo.

    I will censor themselves the language I want to use what is web and iPod app software Kobo... but I don't really like the GLO features, size and speed.  When it connects with ADE as he is supposed to...

    Thanks again for the suggestion and support.  I hope that others benefit from my account of what went wrong past and how I fixed it.

    BTW for Glo users: the problem began, not out of the box (which was perfect), but when I made the mistake to go into the settings and close my Kobo account, thinking I would reconnect when I needed to.  NOT THERE GO.  GLO said immediately that I had to re-setup of the device (why, just because I'm logged into my web account? I'll keep this screed for my email to the technical support of Kobo).  And that's where all the 'fun' started.

    Don't disconnect your Kobo account in the menu settings Glo and Kobo Desktop to avoid like the plague, when you have finished configuring Glo for the first time.  Do not synchronize with anything with Kobo Desktop; Believe me, you will wish you didn't (I learned this with my Kobo Wifi and iPod and it's even worse with Glo and iPod, city of nightmare on many levels I'm in because this isn't a forum of Kobo).  Do your installation of content via ADE.  It can be a nightmare when it goes wrong, but until yesterday ADE had been purrs like a kitten for me and still is today.  Until someone comes up with something better.

    Some software is OK to crush, and some software must always be uninstalled before you reinstall or install a new version.  Some software (such as Kobo) editors are really sloppy on do not make it clear which is the case for users.  An another barbed zinger as Kobo will get me in a day or two.

  • Cannot play videos on Facebook after reset Firefox and add new Flashback... How can I add the exemption of Facebook. Controls look different from the previous.

    I fixed this problem a few years back... but it has reappeared since reset Firefox then reinstalling Flashblock.

    Videos play well anywhere, but on Facebook. Controls all the different aspect now and I can't find the way to exempt Facebook of Flashback.

    Above does not solve my problem, but this fact:

    Go to tools.
    Add Ons.

    Type Facebook.com to whitelist.
