Sorry to hear about the crashes, and thank you for the report IDs. You'll notice that the forum didn't auto-link most of them, and if i try those IDs, they don't show any data so the submission may have failed. Is it possible to open the about:crashes page and click the three most recent report IDs to submit them?

If you haven't already, could you test in Firefox's Safe Mode? That temporarily deactivates extensions, hardware acceleration, and some other advanced features of Firefox that might make it more prone to crashing on some systems.

If Firefox is not running: Hold down the Shift key when starting Firefox.

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

• "3-bar" menu button > "?" button > Restart with Add-ons Disabled
• 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 less crashy?

Yes, I tried to submit them by opening in a new tab in the about:crash reports but i get an automatic page that says:

"You're seeing this page because the crash report you selected was held back from submission. For statistical purposes, we don't need every crash report and sometimes we decline the submission of a crash report as a form of throttling. If you'd like to see your crash report, type about:crashes into your location bar and your report will be automatically submitted to our server where we'll give it priority processing.

Thank you for reporting your crashes." (https://crash-stats.mozilla.com/about/throttling/)

And about the safe mode part, i restarted firefox once without any extensions because everything was laggy and solved the lag issue. This crash always happens in youtube (not instantly but lets say after i play 10 videos or so) when playing a video or when using anything that uses adobe flash player and it wont recover unless i restart my laptop.

I already updated adobe a few times or re-installed and doesn´t work either.

Don't open them in a tab - click on each un-submitted crash report to send it to Mozilla. You only need to do the most recent crash reports - maybe the last 10 or so. That should give us enough information to work with.

ok, so I clicked on the first 15 and I have to mention that any games installed on my pc after this crash happens dont start properly or load properly, youtube videos wont load without seeing a yellow crash line at the top of the browser or adobe flash always crashes after this happens. This issue gets worst in Windows 10 (I went back to 8.1). Here they are:

Thank you for the reports. This is in the same order you listed them:

(1) "ffdshow.ax" - this doesn't make sense, because this is the ActiveX version of the Flash player and Firefox doesn't use that version. Maybe one of your other add-ons embeds this version, or an external video recorder injects it? At least one of the other threads for this report shows that the Protected Mode feature is active. Further down in this message I'll suggest testing with that feature disabled.

(2) (3) Flash plugin hang on "ConsoleCopyStringToBuffer" - there's a bug filed for this, but no resolution or workaround in the system. When I click the "More Reports" link in this bug, over the past 28 day, it shows 24,173 reports ALL on Windows 8.1, which is very unusual, since Windows 7 appears to be the most widely used version of Windows. What is it about this particular version of Windows?!

(4) Very similar to #2

(5) Shutdown hang - this is recorded if Firefox does not complete its file updates and cleanup within a certain amount of time and usually is intermittent.

(6) Nearly identical to #2

(7) Nearly identical to #1

(8) (9) (10) Identical to #2

(11) Similar to #4

(12) (13) Nearly identical to #1

(14) Flash plugin hang on "IsWindow" - this is the latest version of the plugin; there's not enough information to understand what's going wrong here. Over the past 28 days, 99.56% of crashes were on Windows 8.1.

Disable protected mode (Windows Vista and higher)

The protected mode feature of the Flash player plugin has security benefits, but seems to have compatibility issues on some systems. You can disable it using the Add-ons page. Either:

• Ctrl+Shift+a
• "3-bar" menu button (or Tools menu) > Add-ons

In the left column, click Plugins. On the right side, find "Shockwave Flash" and click the More link. Then uncheck the box for "Enable Adobe Flash protected mode" and try that for a day to see whether it helps.

Thanks, about #2 I´ll see if i find any other posts about this issue. I´ll see how it goes for about 2 days and then i´ll be sure to click the "solved the problem" button

I replied before reading your note that you downgraded from Windows 10 back to Windows 8.1. If you didn't have problems on Windows 8.1 before the upgrade/downgrade, you might want to do a full Flash removal and reinstall.

Adobe has an uninstaller and then you can download both the ActiveX version of IE and the plugin-based browser version for Firefox using either browser from the soon-to-be-removed licensing page:

• https://helpx.adobe.com/flash-player/kb/uninstall-flash-player-windows.html
• https://www.adobe.com/products/flashplayer/distribution3.html (you can use either the EXE or MSI version of the various installers)

See also:

Did you install any codec packs recently?

You can check in "Windows Control Panel > Programs" for recently installed programs to see if any suspicious software (Conduit, Search Protect) shows up.

• Control Panel > Programs > Programs and Features > Uninstall or change a program
• Click the Installed column to sort by this heading
