This is a plugin I found recently and really enjoy. It gives you the opportunity to redirect several webpages to alternatives. For example Youtube to FreeTube or Piped. If I search for youtube in Firefox, FreeTube automatically opens and shows me my feed. I like it, I use it, I can recommend it.
It works fine on Fennec, Beta, Nightly, and others using custom collection.
I thought someone might say that, lol. It’s good to know this extension will work that way. I have at least one extension that when using the custom collection method causes none of the extensions in the collection to load or work.
I experience the same issue with some extensions. You never know which extension will work properly using custom collection.
Sadly, you can’t install Librediec directly from Mozilla without collection on Nightly.
