For me, the first practice clip I tried worked...for the first half of the page, then kind of fell apart after that (got the words, but no formatting)
I would switch to pocket except that they don't like to export their whole clip (if you share it to Evernote or OneNote or whatever or within their IFTTT trigger) and I don't like Pocket for long term storage of things. I found a workaround that gives me full text of pocket clips, but it's got some drawbacks and the whole thing just rubs me the wrong way. I love Mozilla's offerings in general, but Pocket seems very weirdly closed off and I'm not into it.
