One alternate way to the asked way by bash and the successor of sessionstor.js, to get the actual url of active browser of active browser tab by bash are the follow ( its sometimes echo p.e "c" and one other like about "[[xx" by unknown reasons to terminal, browser or to forms:

# set focus to adress on browser tab xdotool search --onlyvisible --classname Navigator windowactivate --sync key F6 # copy adress from browser tab xdotool search --onlyvisible --classname Navigator windowactivate --sync key Ctrl+c # get off the focus from adress from browser tab xdotool search --onlyvisible --classname Navigator windowactivate --sync key F6 # delivery of clipboard content to variable clipboard=`xclip -o -selection clipboard` # clear clipboard xsel -bc; xsel -c # echo URL of active tab of active browser echo $clipboard 

One other alternate, to the asked way by bash, can be possible by javascript:

The file looks like compressed by (LZ4):

/sessionstore-backups/recovery.jsonlz4 

JavaScript

let file = 'pfadZurDatei.jsonlz4'; OS.File.read(file, { compression: 'lz4' }).then(bytes => { OS.File.writeAtomic( file + '.json', JSON.stringify(JSON.parse(new TextDecoder().decode(bytes)), null, 1) ) });
