Hi, using FF 28. It crashes when composing emails in gmail. Happens a few time a day. Pls help. Tx

hello, could you provide your latest few submitted crash reports? please enter about:crashes into the location bar, copy the latest few report ids from there starting with bp- & paste them here into a forum reply. this will give us a better understanding what may be triggering those crashes.

Do the crashes still happen if you start Firefox in Safe Mode?

There are other things that need your attention.

Your System Details List shows that you have a user.js file in the profile folder to initialize prefs each time Firefox starts.

The user.js file is only present if you or other software has created this file and normally it wouldn't be there. You can check its content with a plain text editor (right-click: Open with) if you didn't create this file yourself.

The user.js file is read each time Firefox is started and initializes preferences to the value specified in this file, so preferences set via user.js can only be changed temporarily for the current session.

The most recent crash report has an [@ EMPTY] signature, so there is no data available that would make it possible to tell something about the cause of the crash.
The older crash reports show an out-of-memory problem where Firefox uses up all available memory and crashes.

You can try some basic troubleshooting steps like disabling hardware acceleration and starting Firefox in Safe Mode.

Thanks for the reply. Once FF crashes again, I will send the latest report here for diagnosis. thanks.

Thanks.. let me try in safe mode..user.js probably is a file associated with greese monkey ad on.
