I’ve been using Waterfox as my Firefox backup because for some reason my Firefox always crashes within 15 minutes of use, and it’s always when I’m doing impirtant shit like banking or paying a bill. Which is what I typically use the ‘legit’ browsers for, and why I just use LibreWolf for daily browsing/fuckery. Using Waterfox feels like it calls less attention when on a government website as opposed to Librewolf.
Didn’t know it was bought by an ad company once upon a time, but this is also why I spread out my browsing. I also use Ghostery, and I have Brave (for checking how things show up in a Chromium environment when programming) but I don’t like Brave and rarely use it… Point is, gotta have multiple browsers either way.
