Hi, opening Firefoxportable.exe after moving the installation folder is followed by the portable splash screen, then a small window at top right corner of screen shows for a split-second (sometimes with "window id="main-window"
^" in red writing), then firefox closes immediately. Because it doesn't even load, I can't even start in safe mode.
Temporary Workaround:
In prefs.js: deleting the line: "user_pref("extensions.lastAppBuildId", "###########");," .
However, the next time I move the folder, the workaround will need to be repeated. 
Why is this happening and how can I fix it permanently?
