I’m always curious who’s installing extensions like this, that can potentially steal your most private data, when it’s not that hard to just export this information into a PDF yourself. In fact, you can ask most LLMs to do that for you.
Extensions are a huge security and privacy risk and I try to keep my usage of them at a minimum.
I used it for a few long ChatGPT threads with code and tables. Copy-paste usually messes up the formatting, but this saved it pretty cleanly.
