Personally I would argue that allowing users to install extensions, mostly adblockers, you remove what’s probably the single most common real world vector for attackers, ads. So while chromium browsers may be more secure I would say you’re probably less likely to run into a problem with a firefox based browser with ublock origin on it, mobile or desktop.
Working out. I finally realized that my psychological issue with working out was doing a long duration thing that I didn’t like. My solution was a high intensity short workout which doesn’t bother me at all from a mental perspective, so now I do burpees. Quick and over before I have a chance to not like it.
