How to re-install archieved local library (Firefox)?

tanventure

I have archived my local libraries on my PC, then deleted many outdated libraries. My question is how to re-install selected libraries from my archived local libraries in case of a future need?

I have search this forum, but could not find any post, please help.

Thanks

How did you archive your libraries(?) (you mean collections? you'd normally just have one library and perhaps some groups you belong to).
