Was a really great AddOn, doesn't work correctly since some Version Version
4.13.6136. Error report posted, no feedback.

Next problem: After migrating my Firefox/settings to a new computer/system, the import of my aprox. 100 userscripts fails. :-((
The error message "Invalid Userscript. Sry!" allows no inference, where tom locate the error. Its impossible to fix this issue. / AHH, I found a solution: don't export/import as text file, but as zip!
