[Eugene San]

** Description changed:

  Firefox 39 keeps crashing after update from Firefox 38.
  Crashes are random but when idle happens at least once a hour or more frequently when actively used.
  
  When replaced with binaries from Mozilla there is no problems at same
  machine with same profile.
  
- There are many identical reports and seems to be unique for Ubuntu
- build.
+ There are at least 1100 identical reports and they seems to be unique
+ for Ubuntu build.
  
  Below is part of crash report:
