Since I installed Firefox 82 (on Mac OS 10.14) when I'm filling in an online form FF jumps away from the page and brings up an error message telling me that the form is no longer available. Huh? I can use the "Try again" button and it takes me back to the form, but might have lost some of my entries. This happened several times when I was entering data for a bank transfer and has just happened again when I was ordering something online. I've now installed FF 83 but have the same problem. I use only 2 extensions: 1 Password and Privacy Pass. Thank you in anticipation of helping me sort this out.
