@violet the best part about the way I have it setup is that it doesn't matter what browser I use, the sync is the exact same. so like if you have a browser that does 90% of the things, but you need another browser every once in a while, you keep sync with them. and I never ended up using any of the features that sync provides other than passwords and bookmarks so it's everything I need.
though one downside to using a third party password manager is that they can cut the speed of your browser by about a third, so if you're on chromium, the extension extensity lets you quickly toggle the extension off, but you can also press alt+F E(on vivaldi it's ctrl+shift+E, and sometimes it's Alt+F L E), or if you're on firefox, you press ctrl+shift+A to bring up the extensions page.
