For example, I open Firefox and then turn on Transparent Windows at Transparent Windows Extension
But how do I know when it will complete downloading and installing? There's no notification or progress indicator. I visit https://extensions.gnome.org/local/ and also press Super+M keys but haven't found anything.
My platform is Fedora 21 and gnome 3.14.2
[UPDATE] Follow this instruction, I have to manually download zip file, unzip it and
cp -r 'transparentwindows@ellen/metadata.json' ~/.local/share/gnome-shell/extensions/, edit transparentwindows@ellen/metadata.json's "shell-version" to add my current version "3.14". Then
gnome-session-quit logout and login again. Open https://extensions.gnome.org/local/ with Firefox will now allow me to turn on Transparent Windows extension.
But still it's not my exact question, I'm curious about the official way to keep track of the download progress and installation fail log if any.
