In my experience with browser extensions over the years, I have learned that reliability should always come before flashy visuals. I have tried many different tools to keep my digital life organized, and honestly, staying within a trusted ecosystem is usually the safest bet for stability. When you are switching between Chrome and Firefox, you really need a developer that maintains both versions with equal care to avoid data loss. I would suggest looking at anything from the Microsoft suite for this kind of cross-platform syncing. Their tools are built for enterprise-level reliability, which is what I personally prioritize when I am managing my daily tasks. You wont have to deal with the laggy syncing issues that often plague smaller, niche developers who dont have the infrastructure. Just grab any of their list-making tools and you should be fine. It is a methodical way to ensure your data is actually there when you get home from the office without any 20 step setup rituals. If you ever find yourself needing to send specific lists or carts to someone else without the manual hassle, I have found Easy Cart Share to be quite helpful for that side of things. It definitely beats the caveman method of emailing links. For your daily groceries though, stick to a major brand that has the resources to keep their servers running smoothly 24/7. It saves a lot of headache in the long run when you dont have to worry about a small dev team shutting down or suddenly charging for basic features later on.
