firefox crashed [@gtk_style_realize] [@IA__gtk_style_attach] [@gtk_widget_set_style_internal]

... Firefox crashes after being open for an extended period of time

Simply put, if I leave the browser open for a few hours, it will crash.

Nice job catching this issue with -dbg installed. I have been looking for examples of gtk_style_realize bugs all weekend.

Thanks

this is certainly not the bug that is linked as duplicate ... decoupling.

This report looks good. Next step, evaluate stacktrace, find real dupes.
