Firefox crashed, can't get it to work - Mozilla Firefox

  • twain1275069 Sep 30, 2009

    Mozilla reporter opens every time I try to start firefox and says it has crashed. I post a note on the open page to mozilla to fix it but that's a joke. I thought I would uninstall it and reinstall it again but it says I have to close firefox before I can uninstall it, it's not even open anywhere so now i have a catch 22. nothing works

OK, just what do you mean by "it crashed"?
You need to do a ctrl-alt-del and end the firefox processes that are running. I'll bet you have several.
Now start it up again.

  • Anonymous Oct 01, 2009

    When it says it's still open, did you look to see if any firefox processes were running?
    When I get this message, that's what it means.

    Next option--start the computer in safe mode and remove it.

    Also--remember that Firefox is open source and many times the help will come from volunteers.

Firefox crase every 15 minuts plz fix 4 us

Mozilla's Firefox Internet browser is one of the most popular browsers in the world, second only to Microsoft's Internet Explorer.

As of April 2011, Firefox held a 21.63 percent share of the worldwide browser market. Unfortunately, problems with plug-ins, websites and general operating system incompatibility occasionally cause Firefox to become unstable and crash.

To prevent these crashes from occurring again, the cause of the crash needs to be identified so an effective fix can be implemented.

Take note of the action or circumstance that lead to the crash.
Pay particular attention to the timing of the crash and whether it occurred while launching Firefox, when trying to view a specific website, when attempting to download a file or at a seemingly random time.


Repeat the action that caused the crash to see whether it causes Firefox to crash again. Some crashes are caused by memory problems or other external factors and may be a one-time occurrence.

Repeating the action determines whether the crash was caused by errors within Firefox or if there were other factors involved.

Hold the "Shift" key down on your keyboard and relaunch Firefox.
This will launch the application in "Safe Mode," disabling all plug-ins and themes.

Repeat the action that caused the crash; if the problem was caused by a plug-in or theme then the crash will not occur this time.

Open a new Firefox tab and type "about:crashes" without the quotation marks into the navigation bar.
Press "Enter" to load the Firefox crash log listing.

Select the most recent entry and scroll through it to find the name of the plug-in, theme or other component that caused the crash.

Disable or update the component to remove the cause of the crash.
This information should be contained in the "Details>Signature" or "Details>Crash Reason" sections.

Open the Tools menu in Firefox and select "Add-ons" if you cannot resolve the crash problem by disabling or updating a plug in.
Scroll through the list of installed browser add ons, disabling add ons one at a time in an attempt to correct the error.

If the crash occurs when trying to view certain types of content, such as streaming video or other media files, focus in disabling add-ons that are related to that type of content.

Open the Help menu and select the "Troubleshooting Information" option if crashes occur only when attempting to download files.

Locate the "Application Basics" entry, then click the "Open Containing Folder" link to open the folder containing your Firefox profile.

Exit Firefox, then select the "downloads.sqlite" file in your profile folder and delete it.
This removes your download history, eliminating any problems with the file and allowing Firefox to create a new file when it launches again.

Update Firefox.
Some crashes are caused by problems within the Firefox program itself, such as problems with specific operating systems or crashes that occur only in new Firefox releases.

Updates may contain fixes to these Firefox crashes, eliminating the crash problem once the browser update is installed.

Adobe plug in keeps crashing when playing Zynga on facebook. Since this started, also noticed some programs seem slugish. whats wrong?

If you are using Firefox profiles to work with Adobe Reader/Acrobat 9 in the browser, you may encounter a browser crash. This can occur when you have a PDF open in one profile and a normal HTML page in another profile in Firefox, and then you close the Firefox window with the PDF, firefox crashes

This is a bug in Adobe Reader/Acrobat 9 and is fixed in version 9.3 onwards.
