Yeah, I knew about the unavailability of Tabstash, which is unfortunate. It would be the best option.
However, I learned something about Onetab today - I thought it was strange that you couldn't get it to work, when I used it just the other day on Android. But if you look at the FAQs in the Details section (see attached screenshot), it only can save the 'active tabs' as dictated by Firefox Mobile, so in that sense it's not ideal. 
Tabstash would've been my initial suggestion, but it doesn't seem to be available for mobile. Onetab was what I ended up using when I wanted to do something similar to what you're wanting to do.
Wow! I've never run across this site. Even if not on a budget, it has some great ideas and it's presented really well. Great find - thanks!
Weird, seems like a lot of flat-earthers are from the UK. Not sure what your point is.
I'm astounded that this was painted in 1658.
Interesting list. Antennapod is an excellent podcast app - use it every day. I've never found VLC to be bloated though. And am curious about the SyncThing fork vs. regular SyncThing.
Is she a tea-drinker? Maybe a bag of some really nice tea from a proper tea shop, herbal or otherwise. My experience is that tea drinkers really appreciate a nice artisan-style brew. It's an understated but thoughtful gesture.

Thank you for this - looks like it's got an open source, ad-free Android app as well.
