Hello,

Thanks for the fast reply!

Im sorry to inform that its empty In my about:crashes. The next time it crashes i will send and copy the information.

Thanks!

Hello,

Now my firefox crashed again and I got the ID.

bp-04238717-938f-4a29-80a1-fe4b52160104

Thanks!

Once again it crashed.

Here comes one more ID.

bp-b023ce42-80da-4e56-8271-db19d2160105

And here is another one.

bp-b12a2fd7-4e6a-49b0-a0e8-91f9d2160106

The first two crash reports 'flag' lpxpcom.dll - a Last Pass dll. Is Last Pass up-to-date?

The third shows nvwgf2um.dll - which is related to video / graphics drivers. Check for updates for your graphics drivers. And if no updates are found, try disabling Hardware Acceleration in about:preferences#advanced (Options > Advanced tab) = "Use hardware accelrration when available"

Hi,

Lastpass just came out with a new update, so I updated it. But I think it can be the graphics driver that has been messing up. I read in the changelog that they had some errors with previous driver and now released a new version (Nvidia 361.43). So I will test with this new driver and see if it works better.

I will update with status when I have tested this a few days!

Thank you very much for the help!

Hello again,

So now my browser crashed again. Both LastPass and gfx drivers are up to date.

Here is the ID: bp-5e3cf968-06d5-47f9-9d9e-5de2b2160108

Thanks!

Might be related to the amount of RAM and HDD free space available on your machine (does this also occur on any 2nd machine which you may have?).

Perhaps the memory load which FF generates before crashing rises to some unsustainable level, producing a seizure/crash -- should also produce slowdown or non-responsiveness, if so? Use Windows' Task Manager under the "processes" tab to monitor that aspect before the next crash, and look at the "advanced" tab under FF options (Tools|Options) to identify what amount of hard disk space is being used by FF for its cache -- you may want to toggle the box which overrides automatic cache management and input a limit which is consistent with the amount of HDD capacity available if it is consistently being maxed out. Unfortunately, there's no comparable way to limit the max load on RAM (but there really needs to be).

Hello,

I dont really think it has with HDD or RAM to do.

Im running with 16GB RAM and not even half of it is used now when im using firefox and multiple tabs. My harddrive has 201GB free space.

Thanks!

You posted here using the Firefox 32-bit version, which will only 'address' slightly less than 3 GB of RAM - a limitation in Windows 64 with 32-bit applications.

As far as that last Crash Report - two red flags appeared:

msmpeg2vdec.dll = Windows MPEG-2 Video Decoder and nvwgf2um.dll = graphics driver, again

See if turning off Hardware Acceleration in Firefox helps. https://support.mozilla.org/en-US/kb/upgrade-graphics-drivers-use-hardware-acceleration#w_turning-off-hardware-acceleration

Hello,

I have now disabled the Hardware Acceleration. I hope this will fix the problem.

Would a 64-bit version of Firefox help this type of problem? And is there any plans of a such version to come?

Thanks again!

Here we are again, problem still not fixed.

A little update:

I have another program that crashed and it said it was due to gfx driver. So I went to the device manager, right clicked on the gfx-card and selected "Check for new drivers". So windows installed a new driver for the gfx-card. I assumed I had the latest driver after i updated from Nvidias own control panel, but windows update seemed to find new drivers anyway.

So I will run this for some time and see if I get anymore crashes.

Thanks

Ok, so I think i have got a little grasp around this issue.

Like I said in my last post, I updated driver through the device manager instead of using Nvidias control panel. After i did this update via the device manager, I got a notification from the Nvidia control panel that there is a new update for my gfx driver. I installed it and noticed that it is the same driver as i had prior to the update via the device manager.

I knew that using the driver that Nvidia control panel provides will make Firefox crash. So I once again went back to the device manager and updated the driver that windows update provides. The driver that Windows provides is Version 10.18.13.5382 and the driver Nvidia provides is Nvidia 361.43.

So far I have not experienced any more crashes since I have been using the Windows driver. Usually when I look at the computer after it being on all night, Firefox always has crashed, but so far no crash yet.

Hopefully I found the issue causing the crash. I will keep you updated.

Thanks!

Once again I hit rock bottom. Firefox crashed just now again.

Thanks!

Sorry, that type of crash - [@ nsInterfaceHashtable<T>::Get ] - didn't "red flag" any "module" that would indicate the cause.

As far as using a 64-bit build of Firefox, whatever benefits it has over 32-bit Firefox might be offset by the lack of 'whitelisted' Plugins with 64-bit. Only Flash and Silverlight are 'whitelisted' (allowed) in Win64 Firefox builds. The beginning of the end for Plugins with Firefox. All the major web browsers are doing away with 3rd party Plugins; Edge doesn't have them, Chrome is getting rid of them early this year, and by the end of 2016 the New Firefox using Rust / Servo won't need / allow Plugins. HTML5 will "replace" 3rd party Plugins in all web browsers; or so the 'plan' is ...

Try to rename the storage folder in the Firefox profile folder. You can use this button to go to the current Firefox profile folder:

• Help > Troubleshooting Information > Profile Directory: Show Folder (Linux: Open Directory; Mac: Show in Finder)
• http://kb.mozillazine.org/Profile_folder_-_Firefox

You can also try to remove all the cookies via Clear Recent History (Ctrl+Shift+Delete) and set the range to everything with only the cookies selected.

Create a new profile as a test to check if your current profile is causing the problem.

See "Creating a profile":

• https://support.mozilla.org/kb/profile-manager-create-and-remove-firefox-profiles
• http://kb.mozillazine.org/Standard_diagnostic_-_Firefox#Profile_issues

If the new profile works then you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over problems.

Hello,

I think I now have pinned down the issue for my crashes.

To start with, I uninstalled Firefox from my system. I then changed the name of the profile folder, so a new and clean one would be created when installing firefox again. So now I have a totaly fresh install of firefox.

As you probably can see, I have a few addons installed and one of them is LastPass.

I have noticed that when using certain functions in LastPass, firefox crashes. One of the functions is "Generate password". It does not crash EVERY time, but very often.

I noticed that it crashes more often when I do the following:

1. Press LastPass icon 2. Select Generate Password 3. Copy generated password 4. Minimize Firefox

Like i said, it does not crash every time. But it has done it enough numbers of time to understand that LastPass is related to the issue im having.

It happend not so long ago. Here is the ID: bp-636f8ee5-7727-443d-ae67-5b4d62160118

Any more thoughts regarding this?

Thanks!
