webRequestBlocking	Permission	Critical	This permission allows the extension to intercept, modify, or block any web request in real-time before it reaches its destination. Rated Critical because it can modify sensitive data (like passwords, credit cards) before encryption, redirect traffic to malicious sites, or block security updates.
webRequestFilterResponse	Permission	Critical	This permission (Firefox) allows the extension to read and rewrite the body of any HTTP response before the page sees it. Rated Critical because it can exfiltrate page contents in transit and inject arbitrary code into any response.
<all_urls>	Host	Critical	Broad host access — the extension can read/modify content on every website.

Filename options should have an additional option to use both the last part of URL and the tab name, or a custom pattern. Also, sometimes it gets the videos from Private tabs, sometimes it does not. The interface is also overall kinda clunky to use, like, the buttons and overall layout would be much better with some proper care, it does not separate videos found in the list, as in "Found", "Downloading" and "Downloaded". So, mostly the extension is not clear enough about what is happening and I'm just hoping that it will find the file and that I'm downloading the right file, even if I need to click some settings that I'm not completely sure of what they do. Overall, with a bit of hope and fiddling, it tends to work. Could use more work to be more clear about what's going on, but, it does work, and thank you for that!

Does not work, UI is garbage. Does not recognize anything! Tried Facebook and YouTube. The download page gives a lot .mp4's but when I click the preview you get nothing but an empty video or a MIME error. When trying to download a video and open via VLC, nothing happens. ODDLY ENOUGH the ONLY video that works is the test video..... GARBAGE PRODUCT!!!!
