User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:36.0) Gecko/20100101 Firefox/36.0 Build ID: 20150114125146 Steps to reproduce: Test environment: - Windows 7 x64 - latest Nvidia driver (347.09) - Firefox 36, 37, 38 - clean profile (always created a new one during tests) - no add-ons/themes installed - all plug-ins disabled Hardware acceleration is enabled in preferences area. About:config -> layers.offmainthreadcomposition.enabled set to false Visit https://www.google.com/maps/ for example Actual results: Firefox crashes without doing anything on that page. Probably other pages are affected too since Fx36 beta 1 (build 2) crashes a lot. Expected results: No crashes should occur. Preventing crashes is possible by disabling hardware acceleration or setting "layers.offmainthreadcomposition.enabled" back to "true". Since "layers.offmainthreadcomposition.enabled;true" causes tab freezes/hangs since Fx33, using it is not an option. Firefox 33-35 did not have the above issue.

Please provide the crash ID from about:crashes and also post the graphic section from about:support

Are you sure that the crash id is from the crash you want to report here ? The crash id shows a crash in the plugin code and "NPSWF32_16_0_0_235.dll" is loaded. from comment #0 "all plug-ins disabled"....

After clicking on the id link, it automatically added a "bp-" and god associated with that page. Here is the crashreport, Firefox wants to send: http://pastebin.com/TpnfRNP1 I just retried and got more crash ids bp-2e0f8119-5fbe-40b1-9be0-5207f2150116 https://crash-stats.mozilla.com/report/index/2e0f8119-5fbe-40b1-9be0-5207f2150116 bp-11a5267f-d240-4e91-b217-9bf892150116 https://crash-stats.mozilla.com/report/index/11a5267f-d240-4e91-b217-9bf892150116 bp-58ac2c41-4884-41ee-af40-36b4a2150116 https://crash-stats.mozilla.com/report/index/58ac2c41-4884-41ee-af40-36b4a2150116

The bp- in front is correct and bugzilla recognizes such a crash id with a bo- in front and converts the crash id to a link.
