did you write the greasemonkey script or did you use chatGPT to do it?
i used chatGPT to throw together some Perl a while back and it was worthless. by the time i cleaned it up enough to actually run correctly i already realized a better solution
i used LLama LLM by meta and deepseek coder, I started of with Llama 3 70b then updated recently with Llama-3.1-sonar-large-128k-chat.
I just realized the recent update is buggy in that it's no longer creating the x.com embeds/iframes or converting twitter.com links into iframes, none of the embed iframes are being created, so i'm testing scripts to see which one last worked and where a mistake was made.
edit
i just made a minor edit to the scipt and uncommented out this this line
addMirrorLinks(document);
which was at the very bottom, when i did a initial test in just one browser it created two sets of links. i realized 30 minutes later that because it the adding youtube mirrors code was originally part standalone userscript and i just copied and pasted to the end of my existing userscript, i never disabled the other userscript and incorrectly attributed the duplicate links to that one line. turns out I had uncommenting that one line effectively disabled the insertion of youtube mirror links.
i'm still troubleshooting the embed issue.
