Description

image

On my Firefox build, running version 51.0.1 stable, the & symbol appears corrupt as shown above. When Firefox is started in safe mode, the symbols just don't render instead of appearing corrupt (as shown below) - however, if all add-ons are manually disabled and Firefox is run outside of safe mode, the symbol appears like it does above.

List of add-ons:

  • LastPass
  • Min Vid (Firefox Test Pilot)
  • Octotree
  • Private Tab
  • Reddit Enhancement Suite
  • snoozetabs (Firefox Test Pilot)
  • Tab Mix Plus
  • Tree Style Tab
  • uBlock Origin

Research direction

Reproduce the rendering problem in Firefox 51.0.1, first in safe mode and then with the listed add-ons disabled individually. Since no file or test is identified, locate the code responsible for displaying the ampersand and verify that the symbol renders correctly without breaking the reported configurations.
