Firefox doesn't open up even after reinstalling

The window of the program opens but none of the icons are visible. I tried to reinstall Firefox but it didn't help. I don't get the message about any error. My operating system is Windows 7.

Try to disable hardware acceleration in Firefox.

  • Adobe Acrobat hangs when opening PDFs even after reinstall

    Hello,
    I have 2 new Dell systems that are having issues with Adobe Acrobat.  When opening PDFs, either from an email attachement or file from our server, there is a brief hang that lasts 10-15 seconds, during which Acrobat is unresponsive however the workstation continues to respond.  I've since uninstalled/reinstalled, still no luck.  I've also run updates. Problem unresolved.
    Any ideas

    One of our users is having a similar issue with Adobe Reader 9.2 hanging.  Adobe Reader will eventually open after about 5 seconds.  I've found a work around where if I leave a .pdf document open, any other .pdf I click will open up fine (but a .pdf needs to be left open in Adobe Reader).  This is happening only with one user.  Some of the things I've tried that have not worked: repairing, uninstalling/reinstalling, deleting temp files, opening the file with a different account/profile, downgrading to Adobe Reader 8.1.3.  Anyone have any ideas?  This is only happening to one user at my company.  I've searched the forums here and it looks like other people are having similar issues but there's really not a solution to this.  Any help would be appreciated.  Thank you in advance.

  • Firefox crashes upon start up even after reinstall

    I uninstalled, removed Mozilla folder from program files. Downloaded again and tried to restart. Crashed again. This is the report it tries to send over and over again:
    Add-ons: {B7082FAA-CB62-4872-9106-E42DD88EDE45}:3.2,{972ce4c6-7e08-4474-a285-3208198ce6fd}:3.6.10

    I really liked Firefox for the few days I got to use it. This doesn't bode well for future use.

    We're sorry to hear that your Firefox seems to be crashing when you open it. Please perform the following steps to give us a crash report ID that helps us find out more about the cause of the crash.
    #Press the following shortcut to get a Run window: [Windows] + [R]. This should bring up a window that contains a text field.
    #In that text field, enter %APPDATA% and press Enter. An explorer window should open.
    #From that explorer window, double-click on the ''Mozilla'' folder, then double-click on ''Firefox'' and then on ''Crash reports''. Double-click on ''submitted''.
    #Now, you should see a list of files that contain reports. Go to ''View'' > ''Arrange Icons by'' > ''Modified'' to get the most recent files at the top of the window.
    #Open the most recent 5 files with a text editor and copy the IDs.
    #Paste each ID into the reply window on the forums.
    Thanks in advance!

  • Firefox freezes and stops responding even after reinstall

    Hi, I've been a Firefox user for a decade, despite three attempts to switch to Chrome. But this is getting on my nerves. I'm in the middle of something and suddenly the browser freezes - I can move the cursor over whatever bookmarks, menu items, tabs or content but nothing responds. It's exactly as if the entire browser had turned into a printscreen. I get no crash report afterwards, I just close and restart it. This has been going on for quite a few months now. I'm using the latest version by the way.
    Extensions I use:
    Adblock
    Colorzilla
    Diigo Toolbar
    Evernote webclipper
    Fireshot
    Pin It buton
    Video Download helper
    Wisestamp
    Lazarus Form Recovery
    And quite a few other plugins.

    Hello kutez, '''try Firefox Safe Mode''' to see if the problem goes away. [[Troubleshoot Firefox issues using Safe Mode|Firefox Safe Mode]] is a troubleshooting mode that temporarily turns off hardware acceleration, resets some settings, and disables add-ons (extensions and themes).
    '''If Firefox is open,''' you can restart in Firefox Safe Mode from the Help menu:
    * Click the menu button [[Image:New Fx Menu]], click Help [[Image:Help-29]] and select ''Restart with Add-ons Disabled''.
    '''If Firefox is not running,''' you can start Firefox in Safe Mode as follows:
    * On Windows: Hold the '''Shift''' key when you open the Firefox desktop or Start menu shortcut.
    * On Mac: Hold the '''option''' key while starting Firefox.
    * On Linux: Quit Firefox, go to your Terminal and run ''firefox -safe-mode'' <br>(you may need to specify the Firefox installation path e.g. /usr/lib/firefox)
    When the Firefox Safe Mode window appears, select "Start in Safe Mode".
    ;[[Image:SafeMode-Fx35]]
    '''''If the issue is not present in Firefox Safe Mode''''', your problem is probably caused by an extension, theme, or hardware acceleration. Please follow the steps in the [[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]] article to find the cause.
    ''To exit Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.''
    also, any luck if you delete in your [http://kb.mozillazine.org/Profile_folder_-_Firefox#Windows profile folder] the [http://kb.mozillazine.org/User.js_file User.js file] you have ?
    The user.js file '''does not exist by default'''. If you create the file, forget it, if you have not create the file then delete the User.js file, to see if the problem goes away (some programs create and write in the file also).
    thank you

  • I can't open the app even after reinstalation !

    As I said previously, I can't open it even after switched off the iPad, restarted the app and redownloaded it...
    When I launch it, a grey screen appears and then the app crash ...
    Help me please !

    The problems mostly happen when I am using X-Y compare in Library mode. It shows black rectancles over the tops of the sections that contain the photos and these flash. They aren't always the same size, but are only on the top of the section - never big enough to completely cover the photos. Then I get anywhere from one to about four or five extra windows stacked on top of the Lightroom Icon at the bottom of my screen (I use Windows 8) opening and closing, though there isn't enough time for me to click on them and read them because my computer gets so slow that my mouse actin is delayed by a few seconds. And, to shut Lightroom down, I need to use Windows task manager because clicking on the little red box with the X in the upper right corner accomplishes nothing. I have a new Sony Vaio i5 chip and 8Gb RAM. This also hapened on my old computer, though not as often

  • FF 6.0 doesn't open pdf-links, after clicking on "open pdf" error message says file not supported or damaged. IE opens file all right. Please advice.

    Firefox 6.0 doesn't open pdf-links after clicking on "open pdf". I frequently need to do literature searches and I need to view pdf files in the browser. After clicking on the pdf - link of a file the main options are to open or download the pdf. Every time I try to open a pdf-file a blank page and an error message appears saying the file would not be supported or is damaged. IE, however, opens the file all right. I tried various changes in the security and cookie settings without success. Please advice.

    Hi SGckc,
    This document is almost certainly a dynamic XFA form. Unfortunately, our mobile Reader does not support displaying or filling such forms. The application that produces this form embeds this message into the document so that non-supportive viewers (like ours) will display this "error" page when the document opens. I do realize that this is confusing and I would like to add some additional detection to our Reader for this case. However, we've avoided doing this for fear of confusing users even further. Your feedback helps though. Hopefully we'll find a way to detect this case and present a better message to the user like: This form is not supported by the mobile version of the Adobe Reader. Please open and fill it on the non-mobile version of the Adobe Reader for Windows, Linux or Mac OSX.
    Thank you for contacting us!

  • My itunes won't launch even after reinstalling.  Looked in itunes folder and somehow lost itunes library?  HELP!

    My itunes won't launch even after reinstalling.  Looked in itunes folder and somehow lost itunes library?  HELP!

    The first thing I'd suggest is to get a good antispyware checker and give it a go at your system. Some recent spyware has been reported by other users to shut down iTunes or prevent it from launching. From user reports, Ewido seems to be the best at catching it. You can download a free version of Ewido here.
    If that doesn't cure the problem, try deleting the iTunes preference files:
    C:\Documents and Settings\<username>\Application Data\Apple Computer\iTunes\iTunes.pref
    and
    C:\Documents and Settings\<username>\Local Data\Application Data\Apple Computer\iTunes\iTunes.pref
    You might have to turn on "show hidden files" to find them. (Right click "my computer", select open, select Tools menu -> Folder Options. Select View tab, "show hidden files" radio button is in the center scrolling panel.) Delete them or if you want to be able to put them back if it doesn't help, drag them to some other location. This will force iTunes to run the setup assistant the next time you launch iTunes. Note that you'll have to go back and set any preferences you've changed from the default.
    If that still doesn't work, try this:
    Bugie: Perform a Thorough & Complete Uninstall and Reinstall of iTunes/QuickTime.
    Hope this helps.

  • Firefox 4 stops opening new windows after browser window dragged to second display

    Firefox 4 stops opening new windows after browser window dragged to second display. It's weird. Behavior is fine until I drag any browser window to the attached second display, and after this point it stops opening new windows but will still open new tabs in the same window. Restart fixes it until I drag the window back to the second display.
    "Show all bookmarks" stops working too--won't open a new window.
    This is after clean reinstall with total deletion of any Firefox/Mozilla folders and the previously installed app and a restart of the computer.
    Mac OS X 10.6.7
    Firefox 4

    Pretty sure this is either:
    '''Bug 644733'''
    or
    '''Bug 609405'''
    (...and they may be reporting the same thing.)
