I am following the instructions to transfer Greasemonkey scripts to Tampermonkey: How to Transfer All Greasemonkey userscripts to Tampermonkey on Firefox 57+. However the folder "gm_scripts" mentioned in the instructions does not exist on my PC.
Here are the folders that I do have (Click for larger view):
Would you know which of these the scripts may be in?
I am a beginner at using scripts and maybe this is not really necessary, but it is good practice for me.
Apparently GreaseMonkey no longer stores the user scripts in gm_scripts for Firefox. I have Firefox 58 with GreaseMonkey 4.2. I manually added some junk data to one of the user scripts, followed by comparing file sizes for any changed files in AppData, and what I discovered is that the scripts are apparently stored in an SQLite database file located at:
C:\Users\[Username]\AppData\Roaming\Mozilla\Firefox\Profiles\[ID].default\storage\default\moz-extension+++[GUID]\idb\[Number]gyreekansoem.sqlite
I then proceeded to open the database file using a tool called DB Browser for SQLite. Inside the database, the GreaseMonkey user scripts appear to be stored within the object_data table under the data field. The data format is unfortunately not plain text, so I am not sure how exactly to fetch the JavaScript directly from this database field.
If you just need to export all the userscripts, there's a menu item called Export a backup... in the current version of Greasemonkey (tested with version 4.8). This exports all the scripts' folders and files into a ZIP file.
