@theblur-bot771 They're in the "Extensions" folder in the profile folder. Goto the URL opera://about for the profile folder path. Goto the URL opera://extensions, turn on developer mode and click "details" for each mod to see each mod's ID.
With that said, you can't transfer installation status of those mods to Opera on another computer. You have to reinstall the mods. So, you might as well just go back to https://store.gx.me/ to install them.
