Posted scripts to return browser extensions installed in Firefox, Google Chrome, and Windows Edge at https://github.com/krypted/extensionsmanager/tree/main/Windows%20Extensions. There’s a python and a VBscript version of each. The VBScript uses a Set objShell = CreateObject(“WScript.Shell”) statement to create a new instance of the WScript.Shell object and the strExtensionsPath = objShell.ExpandEnvironmentStrings(“%APPDATA%\Mozilla\Firefox\Profiles\%USERNAME%\extensions”) statement gets the path to the extensions directory, so if it’s different for a given environment, make sure to change that per-script. The Set colExtensions = objShell.EnumFiles(strExtensionsPath, “*.xpi”) statement gets a collection of all the extensions in the extensions directory. The Chrome version looks for crx, etc. Might be a way to do these with custom extension types that I’m not aware of so for now ymmv.
