When you download something say a file in Mozilla Firefox browser a green bar starts occupying the browser's icon on task-bar that shows the overall progress of download(s) going on .But, I want to disable this feature. How can I disable the feature ? Also give a way to enable it too.
Don't allow me be the bearer of bad news.
It seems the progress bar overlay is implemented by Firefox, so I doubt if you can disable on Windows. There seems to be no way to disable it on Firefox currently.
However, according to an answer given to this same issue, a possible solution may be to edit certain files in the Firefox Download API that makes it think the download is complete.
