为什么我的添加到Firefox点不了

unable to browse with newest version Tampermonkey

the newest version breaks the browser from starting

Close source since 2018

always opens new tabs itself on all PCs when it makes updates

not open source, maybe it sends all your data to china?

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!

Eh? I install script and nothing? Script list is empty. Looks like none-working addon. Deleting
