Was it by any chance a redirect to 'validate.perfdrive' something or other that then just fails? Freaked me out as it reminded me of the behaviour of those weird search hijackers I haven't seen in a good while.
I really hope so. It's lost my history before but only for a minute or two and I always attributed it to my browser chugging with too many tabs open. At this point I'm just going to wait and see :/
Just automate the watching process too, and get ChatGPT to summarise the content. Even better if you can let it watch with you, give it feedback, and tune it over time so it can make a value call on shows and save you the effort - "yeah I watched that, so you don't have to, you'll hate it".
(/s, but I imagine it won't be in a year or two or with a skilled coder).
Although it is kind of fiddly and needs refreshing a few times.
