Re: Battlefield 3 Download Plugin doesn't work

What? Did you try clearing your internet cache and then closing your browser, then reopening Battlelog and seeing if it then works?

If it still dont work then.............

- Uninstall the Plugin (in control panel>uninstall) then delete the containing folder placed in: C:\Program Files (x86)\Battlelog Web Plugins

Fix for Mozilla FireFox:
- Install the latest plugin
- go to Addons (Firefox menu) -> Plugins
- Search for ESN AND Battlelog
- Set both to: always activated
- close firefox, start it again and it should be fine then

For Chrome:
-Clear Browsing Data ( Settings/Privacy )
-Reinstalling the plugin by logging to Battlelog again
-In the search bar typing the following command: chrome://plugins
-Checking the box Always allowed for ESN Sonar API and Battlelog Game Launcher
-Restarting the Browser
-Log back into Battlelog via Origin (Play from Battlefield4 icon )
-Join a Server

For Internet Explorer 11
-Restart IE 11
-From Internet Options/General tab -> Clear Browsing data -> Delete button
-From Security tab, slide the bar to bottom -> Medium Protection
-In Trusted Sites -> .battlefield.com should be added along with battlelog.battlefield.com/bf4/ and battlelog.battlefield.com/bf3/
-It will require a System Restart in order for the 7 step to be applied.
-Log in again into Battlelog and download again the plugin.
-Join a server.
