I'd like if it could work with Wetransfer uploads too

It restarts (or any other actions) the browser when the download are finished. But I'd like to choose other events for restarting than "download finished", or no event at all (only a click on the button).

I want to close a firefox window or tab with timer.
I olready can adjust timer for system (with terminal in linux as -command:shutdown xx:xx- )
How can I find like that add-on.

Restart didn't work, I tried many times. OS: Win 10 Pro 64-bit with Firefox 53.0.3.

It's a little bit complicated when you want to shutdown. I don't understand why you must download native-client 0.3.8 or windows.zip (install.bat).
