Hi arian30, sorry to hear about the crashes.

If you are getting the Mozilla Crash Reporter form, your Firefox may have logged some data that would help track down the cause of the problem. You can submit that data to Mozilla and share it with forum volunteers to see whether it points to the solution. Please check the support article "Firefox crashes - asking for support" for steps to get those crash report IDs from the about:crashes page, and then post some of the recent ones here.

Also and/or meanwhile, could you test in Firefox's Safe Mode? In its Safe Mode, Firefox temporarily deactivates extensions, hardware acceleration, and some other advanced features to help you assess whether these are causing the problem.

If Firefox is not running: Hold down the Shift key when starting Firefox. (On Mac, hold down the option/alt key instead of the Shift key.)

If Firefox is running: You can restart Firefox in Safe Mode using either:

• "3-bar" menu button > "?" Help button > Restart with Add-ons Disabled
• (menu bar) Help menu > Restart with Add-ons Disabled

and OK the restart.

Both scenarios: A small dialog should appear. Click "Start in Safe Mode" (not Refresh).

Any improvement?

In the address bar, type about:crashes<enter>.

Note: If any reports do not have BP in front of the numbers/letters, click it to submit them.

The crash report is several pages of data. We need the report numbers to see the whole report.

Using your mouse, mark the most resent 7 - 10 crash reports, and copy them. Now go to the reply box and paste them in.

Seems like no crashes are logged.. btw in safe mode it seems to work fine. How do i get to know now which extension is possibly creating the issue ?

Hi arian30, is there anything recent in the "Submitted Crash Reports" section (below the Unsubmitted section)?

Were you getting Firefox crashing closed, or Firefox freezing and needing to be terminated?

If Firefox was crashing and you didn't get the Mozilla Crash Reporter dialog, did you get a Windows dialog or did Firefox just disappear?

If Firefox was freezing when you opened the Options page for some time, like 10-30 seconds, that could be related to Firefox processing your download handlers file. You can rename the file and have Firefox rebuild it. Here's how:

Open your current Firefox settings (AKA Firefox profile) folder using either

• "3-bar" menu button > "?" Help > Troubleshooting Information
• (menu bar) Help > Troubleshooting Information
• type or paste about:support in the address bar and press Enter

In the first table on the page, on the Profile Folder row, click the "Open Folder" button. This should launch a new window listing various files and folders in Windows Explorer.

Leaving that window open, switch back to Firefox and Exit, either:

• "3-bar" menu button > Exit/Quit
• (menu bar) File > Exit (or Firefox > Quit)

Pause while Firefox finishes its cleanup, then rename handlers.json to something like handlersOLD.json. If you see a file named mimeTypes.rdf, that is obsolete, you can delete it.

Start Firefox back up again. Any improvement?

Thanks .. it is working fine now after checking in safe mode. Thanks again :)

It's back. Updated firefox today. Reinstalled, ran ff in safe mode, remove all addons. Still when i open options or try downloading anything, firefox crashes.

I can go into Home, Search, Privacy and Security and Firefox Account in the about:preferences section, but as i click on General, it crashes.

Hmm, it sounds like there is a problem interacting with the Windows file system (opening a file browsing dialog to upload or save).

I don't know if you'll be able to do this, but if you can:

New Profile Test

This takes about 3 minutes, plus the time to test some problem sites/features.

Inside Firefox, type or paste about:profiles in the address bar and press Enter/Return to load it.

Click the Create a New Profile button, then click Next. Assign a name like Dec2018, ignore the option to relocate the profile folder, and click the Finish button.

After creating the profile, scroll down to it and click the Set as default profile button below that profile, then scroll back up and click the Restart normally button. (There are some other buttons, but please ignore them.)

Firefox should exit and then start up using the new profile, which will just look brand new. Please ignore any tabs enticing you to connect to a Sync account or to activate extensions found on your system so we can get a clean test.

Do your problem sites/Features work any better in the new profile?

When you are done with the experiment, open the about:profiles page again, click the Set as default profile button for your normal profile, then click the Restart normally button to get back to it.

Or use the new profile for a while and we can discuss moving over key data files. (Sneak peek: Recover important data from an old profile)

Did as you said but it crashed again on the new profile (Dec2018) clicking Option under Tool , reverted to new profile :(

Some of your crash reports weren’t sent to the Mozilla Servers.

This could also be an problem with the (default) download location (folder) that isn't accessible for some reason (you may have once saved a file to a removable device).

Please see crash recording video: https://streamable.com/s/zh9rm/dfuwxx

Also this crash is not logged, not sure why. All logs are old.

These reports are too old to be useful. The others were not sent to the Mozilla servers.

Let’s do a full clean re-install;

Download Firefox For All languages And Systems {web link}

Save the file. Then Close Firefox.

Using your file browser, open the Programs Folder on your computer.

Windows: C:\Program Files C:\Program Files (x86) Note: Check Both Folders

Mac: Open the "Applications" folder. https://support.mozilla.org/en-US/kb/how-download-and-install-firefox-mac

Linux: Check your user manual. If you installed Firefox with the distro-based package manager, you should use the same way to uninstall it. See Install Firefox on Linux; https://support.mozilla.org/en-US/kb/install-firefox-linux

If you downloaded and installed the binary package from the Firefox download page, simply remove the folder Firefox in your home directory. http://www.mozilla.org/firefox#desktop ++++++++++++++++++++++++++++ Look for, and remove any Mozilla or Firefox program folders. Do not remove the Mozilla Thunderbird folder if there is one.

Do Not remove any profile folders.

After rebooting the computer, run a registry scanner if you have one. Then run the installer. +++++++++++++++++++++++++++ If there is a problem, start your Computer in safe mode and try again.
