Leftovers from previous versions
Even though it's said that after an update, the leftovers from the previous version are automatically deleted, they are not and roughly 200mb remain and have to be manually deleted.
Being picky about the browser size may sound over the top, but Pale Moon seem to stuff their whole application in 87mb and while Vivaldi uses Chromium and the minimum is 300mb, those extra 200mb literally make the browser half a gigabyte, which still sounds bizarre.
Please do something about those leftovers.
@TianlanSha The installer and vivaldi.7z are required for Autoupdate.
They total 168 Mbytes
But sometimes it's completely gone on its own, sometimes it isn't, very curious behavior.
