已经整上谷歌云服务备份了😂谢谢佬抽时间解答

Is there something like this for Firefox?

I had to rewrite it slightly for it to work because values are bytearray, not strings.
I also used python3 which AFAIK is the default on most distros now:

#!/usr/bin/env python3

# Linux usage: ./extract_tampermonkey_script.py "/home/<USER>/.config/<BROWSER>/Default/Local Extension Settings/<EXTENSION_ID>"
#        i.e.: ./extract_tampermonkey_script.py "/home/foo/.config/google-chrome-beta/Default/Local Extension Settings/gcalenpjmijncebpfijmoaglllgpjagf"
#   Mac usage: ./extract_tampermonkey_script.py "/Users/<USER>/Library/Application Support/Google/Chrome/Default/Local Extension Settings/<EXTENSION_ID>/"
#        i.e.: ./extract_tampermonkey_script.py "/Users/foo/Library/Application Support/Google/Chrome/Default/Local Extension Settings/dhdgffkkebhmkfjojejmpbldmpobfkfo/"

import leveldb
import sys
import re
import json
import codecs

pattern = re.compile(b"^@source(.*)$")

db = leveldb.LevelDB(sys.argv[1:][0])

for k,v in db.RangeIter():
    k = k.decode('utf-8')
    m = pattern.match(k)
    if m:
        v = v.decode('utf-8')
        name = re.sub("[\W\b]", "_", m.groups()[0].strip())
        full_name = "%s.user.js" % name

        print("Writing to %s" % full_name)

        content = json.JSONDecoder().decode(v)['value']

        with codecs.open(full_name, 'w', 'utf-8') as text_file:
            text_file.write(content)

for those who cant install that leveldb crap. Install plyvel and try this script chatgpt adapted for me (tested on python 3.8 windows7)

import plyvel
import sys
import re
import json
import codecs

pattern = re.compile(b"^@source(.*)$")

db_path = sys.argv[1]
db = plyvel.DB(db_path, create_if_missing=False)

for k, v in db:
    m = pattern.match(k)
    if m:
        k = k.decode('utf-8')
        v = v.decode('utf-8')

        group_decoded = m.groups()[0].decode('utf-8')
        name = re.sub("[\\W\\b]", "_", group_decoded.strip())
        full_name = f"{name}.user.js"

        print(f"Writing to {full_name}")

        content = json.JSONDecoder().decode(v)['value']

        with codecs.open(full_name, 'w', 'utf-8') as text_file:
            text_file.write(content)

db.close()

For those who just want to copy tampermonkey scripts from one Chrome browser to another, you don't need scripts to just copy the scripts to another browser.
Copy folder C:\Users\YourUserName\AppData\Local\Vivaldi\User Data\Default\Local Extension Settings\dhdgffkkebhmkfjojejmpbldmpobfkfo. If the extension id changes when you will want to do it, look it up in the extension list.
