Works for the most part but sometimes fails to compile the final video and you end up with a corrupted main file and a _tmp_ folder with thousands of small .ts files. Is this a bug? If so, please fix! Also, no matter which dowload folder i pick it keeps creating _tmp_ folder on disk C: which makes Windows super slow and unusable during the download as it creates tons of small files in that folder.
Used to work great for video downloading but has some unwanted side effects that render Firefox completely unusable. Happened to me once when I could not point my finger on it but then I could reproduce this starting any C64 game from https://archive.org/details/softwarelibrary_c64&tab=collection - afterwards even trying to reload a tab wouldn't work.
