Why browser returns error “Extension’s manifest file is missing or unreadable“

It is something that commonly happens if you select a wrong folder or accidently delete the manifest file of the extension or do not name it properly or have changed the format of the file. Double check the extension folder to make sure that source files of the extensions are present else download the latest version of the extension and install it again for your browser.

You have to fiddle a bit and type in the path without the usual C:/Users/ part

Can not change the download folder in the settings. Yes I have CHANGE DOWNLOAD FOLDER enabled. Yes I navigated to the folder I want it to be and selected it but there is no option to choose / save it as my selection from the screen. Other than this, it is absolutely perfect, just what I wanted.

YouTube Vdeo Downloader 15.0.2 does not properlly work on some videos.

i.e. https://www.youtube.com/watch?v=IUjI4BBeyC0

I can only download up to 720p.

However, I’m able to switch to 1080p when watching, which is weird.
