I-Firefox Isithangami Sokwesekwa

Concerned about javascript injection. I was visiting a new website and a user was testing different scripts that run when you click on the notification bell.

I've followed the instructions (image attached) of a clean reinstall. I've deleted temporary files. Ran a Quick Scan from Windows Defender (No threats found). Browsed through Processes to see if anything was awry. Seems all clean from my inspection, but is there something I've missed? Some place I haven't looked? I have restarted firefox a few times, but not my PC.

i get the following error when i try to go into the web page through a facebook portal (https://apps.facebook.com/texas_holdem/?fb_source=bookmark_apps&ref=bookmarks&count=10&fb_bmpos=3_10) ...... the error reads....An error occurred running the Unity content on this page. See your browser JavaScript console for more info. The error was: RuntimeError: index out of bounds

In the game you can click on link to get daily bonus which i did as the game loaded perfectly but when it tried to reopn i got he above error. I have looked at java to try to configure this but cant see any way of doing it

I really need some help on this as i enjoy this game and ply it most days

3 days running I can no longer play Lord of the Board game in Facebook, Getting error TypeError; src is undefined

I have reloaded Java and the game. Problem still exists.

recently i went from version 1904 to 2004 in Win10 and have had nothing but problems in viewing and bringing up websites that I had no problems with in the past. Am I missing something?????
