Enhanced Tracking Protection is a collection of Firefox features that protects your privacy by blocking trackers that follow you online to collect information about your browsing habits and interests. It also includes protection against harmful scripts. If a site seems broken, you can try turning off Enhanced Tracking Protection for that website: # Click the shield [[Image:Fx89ShieldIcon]] icon at the left of the address bar. # At the top of the panel, toggle off the Enhanced Tracking Protection switch [[Image:Fx91ETPbluetoggle]]. The site will be added to your Enhanced Tracking Protection exception list, allowing trackers on it, and the page will reload automatically. #; [[Image:Fx138ProtectionPanelOff]] <!--{for not fx138}[[Image:Protection panel|width=400]]{/for}{for fx138}[[Image:Fx138ProtectionPanelOff]]{/for}--> This will allow trackers to load on that website while keeping you protected on other sites.
