Extenesions not working in Fennec

Hello. I am using Fennec F-Droid build 88.1.1 and i just added Firefox 2 extensions to Fennec in Custom Collection but I can’t seem to use them even if I did what Mozilla told me how to add them . Here is pictures showing it.

Did I do something wrong or what is it? I can’t acess them at all and they won’t load. If I did wrong plesse someone tell me how to do it?

I have recommended extensions working flawlessly.

Use the collection name in the collection url. No space.
