Markor + synvthing
Joplin uses it’s own database so interoperability is not perfect. Markor is so effing cool. That’s on Android. On the laptop I use want ever is best suited for the task. Most often, a vim variant of notepad++
For me i am careful not to trust to many addons. Several addons have “turned against the user”. I trust gorhill and ublock origin. I only install verified by Firefox. Disable when not needed anymore.
Besides that i think Multu account containers cookieautodelete Bitwarden Treestyle tab
I also use vimium although it pains me or had access to everything, and it’s not verified. So it only runs in nonessential windows.
