Comment:

 Active SVG exploits targetting TBB in the wild;

 Having an option to disable the image parser would allow mitigating future

 users download the new version.

 This applies to TBB proper, not just the exceptionally understaffed
 derivatives (eg https://dev.guardianproject.info/issues/8039).
