It’s so unfortunate that Firefox on Android, for some reason, never worked well with password managers (as I understand it, it doesn’t support the APIs that Android has for them). Sometimes it’ll trigger the manager, more often, it won’t. Infuriating and a deal breaker for me.
I’ll give it another go, maybe this has been improved recently.
Edit gave it another crack, gosh, it actually works now!
Ditto! I keep my shopping list in Home Assistant, and always in Home Assistant. The rest of the notes go in Joplin.
I require apps that can sync (and at least work half-decent on mobile) and that are as little of a barrier as possible. Even then, forming a habit took a while.
