hello IAmFridge, you have various malicious addons present. please perform all these steps - maybe they can address the soundcloud issue as well: # [[Reset Firefox – easily fix most problems|reset firefox]] (this will keep your bookmarks and passwords) # afterwards go to the firefox menu ≡ > addons > extensions and in case there are still extensions listed there, disable them. # finally run a full scan of your system with different security tools like the [http://www.malwarebytes.org/products/malwarebytes_free free version of malwarebytes] and [http://www.bleepingcomputer.com/download/adwcleaner/ adwcleaner] to make sure that adware isn't present in other places of your system as well. [[Troubleshoot Firefox issues caused by malware]]

I refreshed Firefox, ran the scans, and still no result. Anything else I could try? EDIT: Hold on, it worked. Thank you so much!
