+/**
+ * Bug 1769762 - Empty out navigator.plugins
+ * WebCompat issue #103612 - https://webcompat.com/issues/103612
+ *
+ * Certain features of the site are breaking if navigator.plugins array is not empty:
+ *
+ * 1. "Likes" on the comments are not saved
+ * 2. Can't reply to other people's comments
+ * 3. "Likes" on the videos are not saved
+ * 4. Can't follow an account (after refreshing "Follow" button is visible again)
+ *
+ * (note that the first 2 are still broken if you open devtools even with this intervention)
