Following what I learned over at https://programming.dev/post/47796780 about Brave I decided to switch to IronFox, which is also recommended by LibreWolf.
I wasn't able to find the damn ~/Bookmarks directory.
I tried to create one under /storage/emulated/0/Android/data/org.ironfoxoss.ironfox/files/ and copied my Brave bookmarks.html file into it, but to no avail. I ended up manually copying the bookmarks into IronFox, since I couldn't find any import function.
The documentation and FAQs are top notch, as in relevant and concise.
I love the developers' opennes about the limitations
My hardware security key - a Yubico Yubikey - didn't work "out of the box" as it did with Brave, but lo and behold, IronFox had a solution. I have never used Android's function to manage passkeys before, so I'm unsure of the security and/or privacy implications.
All in all, I can strongly recommend this browser based on my initial impressions! Also:
Hard agree that bookmark import/export would make transitioning to IronFox much more incentivizing, but aside from that, I love how hardened it is.
Yep. I mean, in this particular case it took me what... Five minutes to switch to a more privacy friendly and ethical option. :D
