bug 1176147 comment 4 "The majority of the drivers showing this bug are using drivers that are more than 5 years old." There are only 8 crashes in the past week for all versions of Thunderbird. Very small volume compared to what it was for version 31. But if HWA were enabled by default .. hard to say.
