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.

1. Press the following shortcut to get a Run window: [Windows] + [R]. This should bring up a window that contains a text field.
2. In that text field, enter %APPDATA% and press Enter. An explorer window should open.
3. From that explorer window, double-click on the Mozilla folder, then double-click on Firefox and then on Crash reports. Double-click on submitted.
4. 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.
5. Open the most recent 5 files with a text editor and copy the IDs.
6. Paste each ID into the reply window on the forums.

Thanks in advance!

You can find more information and troubleshooting steps in the Troubleshoot Firefox crashes (closing or quitting unexpectedly) article.

Hi mfaisal_i

This looks like a problem with the Free Download Manager (all reports have the same [@ vmsfdmff.dll@0x5728 ] signature)

• https://crash-stats.mozilla.com/report/index/bp-4f3aaabf-9459-4a31-9640-cee0d2121222

• bug 789700 - crash in vmsfdmff.dll@0x5728 with Free Download Manager

So you will have to disable this program or extension in Firefox.

yeah i did already but who has to fix this plugin issue ???

If that plugin isn't working properly then its developer needs to fix this via an update.

Try to ask advice at the Free Download Manager forum
