Thanks, David! I haven't had a notification since I disabled everything. Not sure which was the bad extension yet -- I had quite a few that were no longer necessary so I am slowly adding them back when/if needed. I'm sure many will be deleted soon.
Did you figure out which extension it is? I've been having the same issue. Here are the extensions I have on. If you could identify any extensions you also have, maybe we can identify the culprit:
"Adobe Acrobat: PDF edit, convert, sign tools", "BetterTTV", "DownAlbum", "FrankerFaceZ", "GoFullPage - Full Page Screen Capture", "Google Docs Offline", "IG Downloader", "Image downloader - Imageye", "LastPass: Free Password Manager", "RightToCopy", "Story Saver", "Tab Session Manager", "Tampermonkey", "Twitch Downloader"
