We're sorry to hear that Firefox is crashing. In order to assist you better, please follow the steps below to provide us crash IDs to help us learn more about your crash.

1. Enter about:crashes in the Firefox address bar and press Enter. A Submitted Crash Reports list will appear, similar to the one shown below.
2. Copy the 5 most recent Report IDs that start with bp- and then go back to your forum question and paste those IDs into the "Post a Reply" box.

Note: If a recent Report ID does not start with bp- click on it to submit the report.

(Please don't take a screenshot of your crashes, just copy and paste the IDs. The below image is just an example of what your Firefox screen should look like.)

Thank you for your help!

More information and further troubleshooting steps can be found in the Troubleshoot Firefox crashes (closing or quitting unexpectedly) article.

I have already wiped out Firefox with all the data. And reinstalled it as suggested by Twitter support. You can find all my reports by IP **.**.***.**

I can't look up crash reports by IP, Mozilla doesn't store those. Next time Firefox crashes please get the crash id using the steps above.

Ok. Will send as soon as appear.

Do you remember what Firefox was doing when it crashed? Or where?

I arrived from work, logged in and saw a crash report. Previous was on openning twitter.com Another one was while opening yaplakal.com Before crash it is starting to be very slow - and then crash. Uptime was about a day for all the crashes. Version 37 was stable for over a week. But crash where to, not so annoyning though.

You can try to disable hardware acceleration in Firefox.

• Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"

You need to close and restart Firefox after toggling this setting.

Signature nvwgf2um.dll

nvwgf2umx.dll = Dwm.exe = Microsoft Desktop Window Manager

Perform a System File Check to fix corrupted system files http://www.sevenforums.com/tutorials/1538-sfc-scannow-command-system-file-checker.html

See if there are updates for your graphics drivers https://support.mozilla.org/kb/upgrade-graphics-drivers-use-hardware-acceleration

So when to expect a fix from Mozilla for this bug?

Please try the following:

• Upgrade your graphics drivers to use hardware acceleration and WebGL
• If that fails, Turning off hardware acceleration

Please click on the other 3 Crash Reports to send them and then give us the BP- id that appears after submission - they probably weren't sent to Mozilla. I didn't see enough identifiable information to move forward.

IMO, Microsoft Desktop Window Manager isn't enough for us to work with - too generic of a crash. Unless you are running a modified desktop theme, in which case disable temporarily it to verify that isn't causing Firefox to crash ...

Another one: bp-6736be28-e24e-4869-b5cd-e0f272150608

Signature nvwgf2um.dll

Nvwgf2um.dll = NVIDIA Compatible D3D10 Driver = NVIDIA Corporation

Check for updates.

Why the 37 version didn't crashed and 38 started to crash every day. Nothing changed except the update.

Did you try to disable hardware acceleration in Firefox like I suggested above?

Another one: bp-5c975e3d-3baa-4268-b858-6529b2150610

Tryied to disable hardware acceleration.

Did you look for updated Nvdia drivers?

You can try to toggle the layers.d3d11.disable-warp pref to true on the about:config page.

You can open the about:config page via the location/address bar. You can accept the warning and click "I'll be careful" to continue.
