leightweight replacement of TBird & Enigmail - what do you suggest

good day dear community

is there an option that allows me to replace Tbird & Enigmail - is this doable

i heard bout the two systems

https://webpg.org/
https://www.mailvelope.com/

at a first glance they look great. i guess that they will seamlessly integrate on my opensusemachine

it was sometinmes a hassle to get openpgp and tb to work - years ago i had issues with the pinentry and some “assuan-encrypted” files and transfers.
Well today all runs well - but i want to test out some alternatives.

which one you have some experience with? Which one you can recommend.

note i use kpgp to store the the keys - guess that the above mentioned programmes will work with this also…

love to hear from you
