Mozilla Firefox Version (37.0) 37.0.1 Released


Firefox
Update:  Version 37.0 was withdrawn from the release channel due to users experiencing start-up crashes with certain graphics hardware and third party software.  Version 37.0.1 has been released to fix that issue as well as disabling HTTP/2 AltSvc and including one (1) critical and one (1) high security update.

Fixed in Firefox 37.0.1

  • 2015-44 Certificate verification bypass through the HTTP/2 Alt-Svc header
  • 2015-43 Loading privileged content through Reader mode

Mozilla sent Firefox Version 37.0 to the release channel.  The update does not include any security fixes.

Correction:  Although not listed in the Release Notes, it appears that Version 37.0 does indeed include security fixes:  four (4) critical, two (2) high, five (5) moderate and one (1) low.

A major addition included in the browser is called Heartbeat, described as User Voice in Firefox. Essentially, it is a user rating system.  Heartbeat will appear randomly requesting a rating:

which may be followed by an "Engagement" request:

Personally, this seems like a whole lot of nonsense to me and a wasted effort on the part of Mozilla.org to increase its following.  It is nonsense like that that convinces me further that I made the right decision to switch to Pale Moon.

If you do not wish to allow Heartbeat, it can be disabled as follows:
  1. Open about:config
  2. Click "I'll be careful, I promise!" when presented with the warning.
  3. Type selfsupport in the search box
  4. Set browser.selfsupport.url to "" 

Fixed in Firefox 37


  • 2015-42 Windows can retain access to privileged content on navigation to unprivileged pages
  • 2015-40 Same-origin bypass through anchor navigation
  • 2015-39 Use-after-free due to type confusion flaws
  • 2015-38 Memory corruption crashes in Off Main Thread Compositing
  • 2015-37 CORS requests should not follow 30x redirections after preflight
  • 2015-36 Incorrect memory management for simple-type arrays in WebRTC
  • 2015-35 Cursor clickjacking with flash and images
  • 2015-34 Out of bounds read in QCMS library
  • 2015-33 resource:// documents can load privileged pages
  • 2015-32 Add-on lightweight theme installation approval bypassed through MITM attack
  • 2015-31 Use-after-free when using the Fluendo MP3 GStreamer plugin
  • 2015-30 Miscellaneous memory safety hazards (rv:37.0 / rv:31.6)
