Firefox for Android Support Forum

Up until the last few days I had bookmarks, shortcuts etc saved on my phone and Firefox browser. Today I went to click on a shortcut that I regularly use, only to find it had been completely deleted from my phone! How did Firefox get access to my phone to remove these and to completely clear my history, bookmarks, shortcuts etc??? I never gave permission to access or to delete anything from my phone or browser!

When I click on the scan feature next to the FireFox's search box, FireFox only shows a black screen. Same issue exists when I try to sign in to my FireFox account using the QR code scanner option. My camera outside FireFox works fine.
