Description

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.
