The videos show only the upper-left corner of the image during playback.

When I try to play a video in Firefox (23.0) on my Mac, all I can see is the fourth upper left of the video image.

When I try to display the same video in Safari it works fine. The entire image is rendered.

Mac OS X 10.8.4

Hello

There are a few things that could be the cause. Please can you try the following:

  • Check the Adobe Flash plugin is updated to the latest version
  • Open Firefox in Safe Mode and check if the problem repeats. If this isn't the case, then most likely an Add - it is at the origin of the problem.
  • Try turning off hardware acceleration - Options > advanced > General > uncheck "use hardware acceleration when available.
  • Try to disable "protected mode" in flash player or go back to the Flash 11.2 drive. See this thread for more details support: Flash video only showing a quarter...

I hope this helps. If this isn't the case, then I would try a Firefox Reset. It will return its default settings Firefox but will keep your browsing history, bookmarks, etc..

  • extra frame created in the upper left corner of the scene when exporting .mov only when the 3D rotation tool

    Hi, I really need help because my deadline is imminent, and I looked all over for an answer but have found nothing... I use Flash Professional CS6 on a Mac and have not had any problems to export before .mov until I tried to use the 3D animation tool. A copy of the first image in the upper left corner of the scene - but it shows not in the timeline panel, or when you test the movie. It appears in the preview by choosing export options and stays there during export. I did about 5 different tests and they all have the same problem - it will only go away if I do not use the 3d rotation tool. Problem is that I really want to use this tool to get the effect I want!

    Thank you very much in advance!

    I could easily create the same problem, even in the current version of Animate. The only solution I could understand was to put a keyframe of Tween non - 3D before where the 3D Tween starts. Just frame 1 look exactly as it does now, only to do tweening 3D pieces start from frame 2. It then exports frameless glitch.

  • Show 'the story' 'bookmarks' etc. on the upper left corner

    I returned from vacation and had malicious software. In addition, I don't have the usual tabs in the upper left corner when my home page opens. How to bring back these tabs?

    Were you able to remove malware? Our technical support article lists the tools free other Firefox users have found useful: Troubleshooting Firefox problems caused by malware.

    If the bar classic menu set is missing, you can display it temporarily by pressing the ALT or by pressing F10.

    To be displayed, you can use one of the following methods to display the list toolbar, and then select it there:

    • Right click on a place empty on the tab bar (or the button '+')
    • Press the Alt key to activate the classic menu bar > view > toolbars

    Does it work?

  • After FlashPlayer 11.04, a site with videos, like YOUTUBE opens a separate process and videos appear in the upper left corner and cannot be moved.

    After update to a version after FlashPlayer 11.02 when you open a window with flash videos on, next to the Firefox process in the taskbar appears a new process with the Flash Player icon and the video window is placed in the upper left corner and cannot be moved. If there is more a video on this page when you click on that Flash Player icon, you can see a list of all the videos.

    Using Flash Player 11.02 this problem does not occur and I used this solution for quite awhile, but now, if I use this version, I get a black window with an error message on security reasons, but if I click on it it plays without any problems. Although in a few Web sites that require Flash, he says he needs at least version 10, but I 11.02 but does not recognize it and ask to be upgraded.

    It's very weird because that doesn't happen in my laptop, I have a desktop computer with the exact same windows and version Firefx and this happens. I already tried uninstalling Firefox completely and even remove all plugins and extensions, and the problem persists.

    Uninstall Flash player also solves this, but then I wonder to upgrade the Flash player. This problem occurs in Chrome or IExplorer 10:

    Recent crashes of some multimedia content (this includes the Youtube videos, some flash games and other applications), in collaboration with Firefox are most likely caused by a recent update of Flash 11.3 and/or Real Player browser plugin to malfunction.

  • SQL DEVELOPER DATA MODELER tables seem to be read-only and make it a symbol of the string in the upper left corner

    I have a lot of tables in my data model.  I have three relational models defined in this file.  In one of the models, all tables seem to be read-only.  They all have a string in the upper left corner of the box.

    I use version control, so that are not archived or something like that.

    How to unlock these items?  Why they seem to be locked?

    Thank you

    Must not have been involuntary - you should have physically moved and dropped the tables/entities from one model to the other.

    If you want to copy them and be able to change in the future, use instead of copy / paste.

  • Was a change made? : before the jpeg photo showed up at the upper-left corner of my screen, with a white background for the screen. The image now appears in the center of the screen, and the rest of the screen is completely black.

    By the way, when I put the url in Safari, it's the same as before, namely the image appears in the upper left corner, and the bottom of the screen/monitor full is white.

    You can try it with this URL to jpeg:
    http://www.antiquegamblingchips.com/Crest/bison.jpg

    Yes, it is a new feature in Firefox 11, which was designed to improve the readability of images. You can install the https://addons.mozilla.org/en-US/firefox/addon/old-default-image-style/, which restores the change if you don't like it.

    (does not work on Vista)

    Then, you can open any folder containing

    Just right click the selected image files and
    Choose resize images in the menu. You
    can select a picture or an entire group.
    Just open a file and go to... Edition / select all...

    (Tip: even if you resize the Photos to the same)
    ... original size the size of the file will be greatly
    reduced).

    The program will place the resized in copies
    the folder with your originals.
    (Tip: * never * overwrite your originals)

    To ensure that images in both portrait and
    landscape orientation are resized to the
    same dimensions... go to... Advanced...

    IOW... for 600 x 800... Enter 800 in these two areas.

  • Need help! Does not start. Only get '_' in the upper left corner.

    Hi, have the following computer:

    HP-Pavilion model: KZ849AV-ABA s3500Z

    Running: win 8.1 (32B) 2G ram

    Have not had any problems I know, so far.

    Run norton regularly, no problem.

    Stop the machine to get out.  Returned, tuned back on and now will not start.

    It lights up, passes in front of the screen for "F9" "F11", etc.

    Then crashes on startup with a single "_" in the upper left corner.

    No beeps or error messages.

    Have you tried several attempts to diff power off, unplug, etc..  Same results.

    Have tried to interrupt the boot to make "diags", see the boot menu.  Everything seems fine, from what I can tell.

    Don't know what else to do.

    As mentioned, saw no problem before that to my knowledge.

    It helps the tight connections and no keyboard activity.

    Possible victory 8.1 automatic update when the last stop arrived.

    Recovery disks, I did several months ago when I upgraded to OS to win 8.1

    But I don't want to go down that path and reload everything.

    Any ideas how to check the boot sectors, chkdsk, etc.. ???

    Thanks in advance,

    Hi guys, thanks for all your comments.

    I managed to understand.

    I used the 'flash' player who made victory - 8.1 you create during the installation of win - 8.1 fresh.

    It's like a recovery disk.

    I started off of him and was able to use Diagnostics out of it to check the hard drive.

    He said it was to fix hard drive errors, then restarted.  Got the same new cursor. Then run this process again.

    Got mesg diff on the correction of hard disk errors, please wait.

    It restarted again and is came fine.

    Several reboots confirm the problem disappeared.

    I think that probably the hard drive boot sector becomes corrupted.

    I'll keep and eye to it and document, we had this problem with the machine.

    Will chose to replace the hard drive or buy a new machine.  Which ever option the woman wants to take (his machine).

    Thanks for your comments.

    PS You forgot to mention that I disassembled the machine and cleaned carefully.  Back together and restart with the same problem.  Then I did the above stuff.

  • Firefox ESR 24.8.1 - Flash Video shows only 1/4 of the image with Mac mid-2014, Retina Display

    Question: Flash - YouTube, flat Anywhere, Nickelodeon (only three tested) movies all show only top left 1/4 of the screen.

    Perceived the question: given that the retina has double the number of pixels, only the 'real' number of pixels is used, who is half - half higher, and half left, is only the upper left corner.

    Flash version 15.0.0.152

    Mac OS 10.9.5

    Hardware problem: Retina Display.

    Browser: Firefox ESR 24.8.1 (updated)

    Additional notes: changing playback of YouTube's Flash player to HTML makes the reading of the work.

    Moving the window to an external monitor (no retina) makes reading flash works.

    This is only the case for playback flash on the monitor of the retina; not for the non on the retina, no flash on non-retine.

    My question: how to make this work on my retina display? The choice of only possible browser for me are firefox and safari, and I really want to avoid safari for other reasons.

    Well...

    It turns out that the passage of 24.8 Esr Firefox with the non-beta plugin to 31.1 ESR Firefox with the beta plugin solves.

    Confirmed - it works fine on both sites tested so far which gave me bad.

    Now I just a new GUI on firefox to get used to... (at least it was only once a year now.)

  • I installed firefox 16 and when it happens my whole screen turns a reddish color and nothing appears that firefox symbol in the upper left corner.

    I have always used firefox. Two days ago, when I opened it, my screen becomes reddish and the firefox emblem is in the upper left corner and nothing else is on the screen--no text, no command, nothing. I uninstalled and installed again, same thing. Help!

    Thanks for the suggestions, but on the contrary, I restored my system to 2 days when everything worked correctly. It's all working now. The only great thing that has happened in these two days was a Java Update installation. I wonder if this has a conflict with Firefox. I have not applied this update of Java at that time.

  • Where is the back botton arrow in the upper left corner of the Office?

    Why and where is the back botton arrow in the upper left corner of the desktop, or the computer? The arrow that you can click if you want to return to the previous page of your screen?

    Show customize them with view > toolbars > customize

    then in the lower left corner of the dialog box customize, you want what he read

    Some things like the application windows and Finder can be trained over time to reopen at a certain place. However, I find that even that is affected and you miss out after stop and put in reverse.

    The best way to keep all window locations is only sleep and wake the system.
