HUD appears when pressing Alt+Left or Alt+Right to navigate in Firefox

[Alex Peters]

In Firefox, Alt+Left and Alt+Right are used to navigate backwards and forwards in the current tab's page history respectively.

If these key combinations are completed quickly enough, the HUD erroneously appears immediately afterwards.

"Quickly" is the key here; if the keystroke is completed at a slower rate (e.g. slower than the time between a user holding down Alt and the current window's menu bar appearing), the HUD does not appear.

This problem does not seem to occur with all Firefox Alt+ keyboard shortcuts. For instance, I can hit Alt+1, Alt+2 etc. to switch between tabs as quickly as I like and the HUD does not appear in these cases.
