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 paste them into your response here.

Thank you for your help!

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

Ok, here are the 3 reports:

bp-d2f711cd-ebea-498f-8796-967ab2140209 bp-cccd8628-70bd-4fa7-a995-e656c2140209 bp-63154d06-c20c-4d21-b5fb-661e72140209

I've done some testing and the crashing issue and I have found something odd. If I open in the fresh install, 10 tabs and close Firefox, no crash. I did it again, this time one of the tabs was soundcloud. When I close Firefox with the tabs still open it will crash every time without fail. If I try youtube as one of these tabs there is no crash. I've made every plugin ask first, but when I go to soundcloud it doesn't ask for any plugin to activate.

It would seem to me the issue is with Javascript perhaps? If I enable it to use soundcloud, close the tab and then close Firefox it still crashes. I don't know what else I can do.

Try to set the Boolean pref media.windows-media-foundation.enabled to false on the about:config page to disable the built-in HTML5 media player.

You can open the about:config page via the location bar

Tried that, seemed to work, allows me to play soundcloud but after leaving FF open for a bit doing nothing I Just got a crash, for no reason. I wasn't closing FF, I just left it open. bp-3a5f5e18-93d4-450f-91c3-ec7492140210

Same old, same old.

Try to disable hardware acceleration in Firefox (you need to close and restart Firefox).

• Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"
• https://support.mozilla.org/kb/Troubleshooting+extensions+and+themes

In Firefox Safe mode these changes are effective:

• all extensions are disabled (about:addons)
• default theme is used (no persona)
• userChrome.css and userContent.css are ignored (chrome folder)
• default toolbar layout is used (file: localstore-safe.rdf)
• Javascript JIT compilers are disabled (prefs: javascript.options.*jit)
• hardware acceleration is disabled (Options > Advanced > General)

• plugins are not affected
• preferences are not affected

That seems to (for now) fixed the crashing issue. However, as you may guess, performance is awful now. Google maps is horrific to use and browsing in the general feels sluggish. But maybe this narrows down the crashing issue somewhat.

Still not sure what to try next, I can't put up with this speed, it's like browsing in the web in 1998.

Try to set the gfx.content.azure.enabled pref to false or if this didn't help disable Direct2D by setting the gfx.direct2d.disabled pref to true on the about:config page and leave hardware acceleration otherwise enabled.

That way you still have the benefit from hardware acceleration, but may not suffer from rendering issues.

You can also try to uninstall Windows update KB2670838 if you have this update.

I have disabled the gfx.content.azure.enabled pref and re-enabled hardware acceleration. So far so good. No crashes with soundcloud. Will do a soak test and report back.
