Chromium work well.

Do you have a crash report? https://developer.mozilla.org/en-US/docs/Mozilla/How_to_get_a_stacktrace_for_a_bug_report

I couldn't manage to have a crash report for now. Firefox make the computer totally crash again. To be clear, when I experienced the bug for the first time, Firefox made the computer totally crash on Google Maps. These days it was only Firefox that crashed on Google Maps. But now, as I said, Firefox make the computer totally crash again. I maybe have found the culprit. I should have said that I use a "user.js" file with these entries: // PERFORMANCE user_pref("layers.acceleration.force-enabled", true); user_pref("layers.offmainthreadcomposition.enabled", true); user_pref("layers.offmainthreadcomposition.async-animations", true); user_pref("layout.frame_rate.precise", true); user_pref("webgl.force-enabled", true); user_pref("webgl.msaa-force", true); user_pref("html5.offmainthread", true); // PRIVACY user_pref("loop.enabled", false); user_pref("extensions.pocket.enabled", false); user_pref("privacy.trackingprotection.enabled", true); user_pref("geo.enabled", false); user_pref("browser.safebrowsing.enabled", false); user_pref("browser.safebrowsing.malware.enabled", false); user_pref("dom.event.clipboardevents.enabled", false); user_pref("browser.send_pings", false); user_pref("dom.battery.enabled", false); // USABILITY user_pref("browser.tabs.loadBookmarksInBackground", true); It seem that is "user_pref("layers.acceleration.force-enabled", true);" that make Firefox crash. If I set it to false Google Maps works. To confirm with a clean profile, Firefox crash on Google Maps with just this setting enabled "user_pref("layers.acceleration.force-enabled", true);". Weirdly it make Firefox crash only on Google Maps. Unfortunately I, and a lot of people I guess, need this feature to get rid of tearing. I hope we can find a fix ! Thanks !

"layers.acceleration.force-enabled" is releated to hardware acceleration. Does Firefox crash in safe mode (HWA is off in safe mode)? https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode Anyway you can use your current profile with HWA disabled from the options: https://support.mozilla.org/en-US/kb/forum-response-disable-hardware-acceleration

Oh, and can you type about:support in the location bar and copy here the section "graphics".

Firefox doesn't crash in safe mode. It don't crash too with HWA disabled. Here is the section "graphics" Accélération graphique Fonctionnalités Composition OpenGL Zoom/Panoramique asynchrones aucun Rendu WebGL nouveau -- Gallium 0.4 on NVC1 Décodage matériel H264 No GPU 1 Actif Oui Description nouveau -- Gallium 0.4 on NVC1 ID du vendeur nouveau ID du périphérique Gallium 0.4 on NVC1 Version du pilote 3.0 Mesa 12.0.2 Diagnostics AzureCanvasAccelerated 0 AzureCanvasBackend skia AzureContentBackend cairo AzureFallbackCanvasBackend none CairoUseXRender 0

A similar bug is reported against Nouveau https://bugs.freedesktop.org/show_bug.cgi?id=97462

But since Chromium work well not sure if the problem is in part from Nouveau.

Right, you're forcing acceleration on the version of the driver that doesn't support it well. It's likely Chrome would crash if you were to force acceleration there. Good information though, identifying which driver version has problems, thanks!

I activated dri3 on nouveau (with the following user.js) and firefox doesn't crash anymore on google maps ! // PERFORMANCE user_pref("layers.acceleration.force-enabled", true); user_pref("layers.offmainthreadcomposition.enabled", true); user_pref("layers.offmainthreadcomposition.async-animations", true); user_pref("layout.frame_rate.precise", true); user_pref("webgl.force-enabled", true); user_pref("webgl.msaa-force", true); user_pref("html5.offmainthread", true); user_pref("gfx.content.azure.backends", "skia"); user_pref("browser.tabs.remote.force-enable", true); // PRIVACY user_pref("loop.enabled", false); user_pref("extensions.pocket.enabled", false); user_pref("privacy.trackingprotection.enabled", true); user_pref("geo.enabled", false); user_pref("browser.safebrowsing.enabled", false); user_pref("browser.safebrowsing.malware.enabled", false); user_pref("dom.event.clipboardevents.enabled", false); user_pref("browser.send_pings", false); user_pref("dom.battery.enabled", false); // USABILITY user_pref("browser.tabs.loadBookmarksInBackground", true); user_pref("reader.parse-on-load.enabled", false); user_pref("reader.parse-on-load.force-enabled", false);

Seem to work with nouveau dri2 on Fedora 25.
