I also use ddg but im pretty sure they sell your data to microsoft. Also firefox has been under fire for privacy complaints and censorship. If privacy is a concern you might aswell find another solution.
If you just want it to work Id try waterfox (what i use), or some other fork of firefox that focuses on privacy, ive also heard good things about ungoogled chromium.
Hope that helps
Im using the free version of boost, but theres a whole bunch of features that dont work (such as not being able to view saved or upvoted posts). The main thing I was looking for was a full page feature each post is a page that can be swiped to the right to view the next post.
