Firefox got mosaic after browsing for a while

There is a kind of mosaic of problems appear randomly while I'm browsing the internet. What happens to my mac and windows 7.

Please refer to the photo of the attachment, you can see on the top right, there is a white block. It keep flashing randomly and blocking the image while I am browsing.

I thought it was my graphics card problem at first, but I found that this also happens to my macbook.

Please tell me how I can solve this problem? As it has become very annoying.

Thank you very much!!!

Hi, this may be caused by hardware acceleration or extension, so please try Firefox Mode safe mode to see if the problem goes away. Firefox Safe mode is a troubleshooting mode that temporarily disables hardware acceleration, restores some settings and disables add-ons (extensions and themes).

If Firefox is open, you can restart Firefox Safe mode in the Help menu:

  • Click the menu button

    click Help

    then select restart with disabled modules.

If Firefox does not work, you can start Firefox in Mode safe as follows:

  • On Windows: Hold down the SHIFT key when you open the desktop Firefox or shortcut in the start menu.
  • On Mac: Hold the option key during the startup of Firefox.
  • On Linux: Exit Firefox, go to your Terminal and run firefox-safe-mode
    (you may need to specify the installation path of Firefox for example/usr/lib/firefox)

When the Firefox Safe Mode window appears, select "start mode safe."

If the problem is not present in Firefox Safe Mode, your problem is probably caused by an extension, theme or hardware acceleration. Please follow the steps described in the section Troubleshooting extensions, themes and problems of hardware acceleration to resolve common Firefox problems to find the cause.

To exit safe mode of Firefox, simply close Firefox and wait a few seconds before you open Firefox for normal use again.

When find you what is causing your problems, please let us know. This might help others with the same problem.

  • 12 Firefox became the slowest browser for the loading of web pages. Is there a solution?

    I've been using Firefox as my default browser for years. However, beginning with FF11 and continues with FF12, it became so slow to load web pages that it has become practically unusable. IE, Opera, and Chrome are all must faster. If someone knows a solution, I'd love to hear about it.

    I live in rural Texas and it is true that my ISP is not the fastest 'high speed' in the world - 1, 5 - 2.0mbps, but other browsers can handle this OK. No Firefox.

    I tried to disable ALL add and extensions. I got FF up to bare bones - without tab, no whistles or bells - and yet it's very slow. I've already replaced my router - no help. I tried to empty the memory cache, settings, same run the «Speed Up My Firefox» software Nothing seems to help.

    It is clearly a problem of Firefox. I'd like to go back to Firefox, but I don't have the patience to wait while he takes his own load time of web pages.

    Any ideas?

    Tom

    I edited this post to remove some questionable information and keep only what I know works for me.

    The setting network.http.keep - alive false seems to provide the greatest improvement, but I think that setting network.http... Max-connections to 64 maybe helped a little in my case, since I have a slow connection 'broadband '.

    I also reinstalled FF12 with these changes, and the problem seems to be resolved.

    For now, this seems to have solved my problems. If things start going downhill, I will return.

    Thank you all for all the help and suggestions.

    Portable computers support two monitors. The problem may be caused by two reasons:

    1. incorrect power setting.

    We have 2 servers RDP with Windows Server 2008R2, we recently updated firefox since version 9 version 17.01 because of flash plugin crashes. After that the firefox update blocks very regular for each user.

    After you open a site, we see it for a fraction of a second, then
    The error message depending on whether we get:
    "Firefox has stopped working".

    This is the case for most sites, some sites work however, as www.google.nl
    Sites that do not work for example:
    www.YouTube.com
    www.nu.nl
    www.UNOX.nl

    I thought it would be flash again.
    What we tried:
    -Firefox to uninstall and reinstall again.
    -Uninstall Flash player and install it again.
    -Disabled all add-ons
    -tried save mode

    I'm a little short on options.
    Any help would be much appreciated!

    Kind regards

    Joost

    Luckily a colleague of me figured it out!

    It turns out that the cause of the firefox crashes came from a security layer installed with the ESC Secure Layer that uses an application called Manager of funds
    The dll that the accident was referring is used by this program. Find that out was the hell google is now filled with the nonsense of 'check your PC for malware' stupid on a search for the dll.

    After removing the application, FF works fine again without crashing.
    So it seems a compatibility issue with Firefox and Money Manager

    Thanks for the help and I hope that someone in the future will have something on the solution we have found.

    Cheers!

  • Is it possible to set Firefox to remember the story for a while rather than all or nothing?

    In previous versions, there was a choice to remember the navigation history for a number of days, but in the current version, the only choices seem to be remembering the story or don't remember the story, with no way to customize in the meantime. I don't want to have to clear my history and cache manually all the time, but I don't want not erased whenever I close the browser, either. Customization feature has been removed entirely, or have I missed something? And if she was completely removed, could it please be reduced? It is useful for those who want their browsing history more old should be deleted without deleting the history.

  • How can I make Firefox (9) the default browser for Android (2.3.4) on a Motorola Bionic (5.5.893.XT875)?

    Several suggestions online (for example, through the Manage Applications-All-Browser, or the settings of Firefox) have not worked. Browser 'faults clear"is grayed out, probably because there is no set of default values, and I've yet to find how to put everything. Firefox has no button 'Settings' and 'Website Options' or 'Préférences' means making FF by default. Whenever I click on a link, FF appears as an option, however, and it works fine.

    You need get the Actions dialogue box to appear and check the use as default action at the bottom of the list. One of the common ways for this to appear is to follow a link to a program of e-mail or a social network like Facebook or Twitter application.

  • How to restore a previous session after firefox closed and deforested browsing history, is still any chance to get it there?

    Accidentally closed down the pc and firefox did not return with option restore previous session in the first screen even in history-Restory previous session is gray. My settings are own history after closing firefox.
    Y at - it no change to return on my tabs from previous session even browsing history has been cleaned? I'd appreciate your help!

    In general, FireFox will behave in 1 of 3 ways when restarting after a stoppage.

    1 kill Shutdown
    This occurs when the FireFox process ends with a TerminateProcess() appeal or if the process of FireFox crashes. It's a dirty, no cleaning is done. When restarting after this FireFox will show a dialog "well, this is embarrassing' with options to restore the items selected from the previous session.

    2 force Shutdown
    This occurs when another process ask FireFox to shut down cleanly (for example, a reboot of the PC) by a call to ExitProcessEx() and does not ask confirmation of the user. Normally, when this type of shutdown happens, Firefox will just restore all tabs and sessions without asking. However if Firefox is set automatically delete the history on shutdown, it may not. I suspect that this is your case. I would suggest to the FF team remove that history should be ignored in this case, only a stop of the user must delete the history.

    3 judgment of the user.
    That's when said user Firefox close (by selecting exit or by closing all the tabs etc...). Confirmation is requested to close all tabs (if enabled and more than 1 tab is open). When the computer reboots, nothing is restored.

    Unfortunately, if you have enabled clear auto history, there is no way to recover the previous session. I'm sorry.

  • I like Firefox, I got Chrome as Firefox won't open Javascript for hulu. I've tried everything.

    I get an error saying my browser or security does not javascript open when I try to get on hule. I have tried everything to implement uninstall reinstall Firefox, clear the cache and cookies and make sure that javascript is enabled, uninstall and reinstall java. I have no problem using Chrome. I prefer Firefox, but I have no choice.

    Fortunately, Firefox didn't need the Java plugin to run JavaScript. It is built in.

    If JavaScript has been disabled, many sites Internet would shout about it. If you see this problem on Hulu, the likely problem has some other cause, such as some selective filtering by an add-on or external security/privacy software.

    Many users have recently increasingly aware of privacy and two changes made to their cookie settings or installed extensions that stop a few information to reach Web sites. While this reduces followed, it can also cause certain features of the site to break.

    As test, try to use Hulu in Mode without failure of Firefox in a private browsing window. This initiative will allow to bypass the cookie settings restrictive, as well as other behaviors extensions filtering, so whether those who are a factor.

    Hi B Odd Andersen,

    I want to clarify if your computer seems to be sleeping or it completely closed after being idle for a while.

    Method 1: If the computer is in power saving mode, check if you can wake the computer from this State by moving the mouse or pressing any key on the keyboard.

    Method 2: Change the power to another and check to see if the problem persists
    Change, create, or delete a power plan (scheme)

    Method 3: check the logs in event viewer for more information on auto-off down

    Open event viewer

    What are the information in event logs? (Event Viewer)

    Activate the update or disable automatic
