I'm not technical but there should be an easy way.
In what sense are you using the word 'should'?
Technically, if FireFox or Evernote holds it's files "open" or "in use" then it doesn't make sense for other programs to try to use them or to act as if they are going to be in any predictable state.
If you mean should in the sense that the computer industry should have solved this problem, then it is solved for some classes of program - always on database servers still need backups, so you instruct them to put the database in a consistent state, take a copy, and then instruct them to carry on. Previously, you would shut them down, take a backup, then restart them.
But to use that solution, both the database and the backup system have to be extended to support this, and to have it on a normal user system, every program would have to have a way to accept that kind of instruction from outside, and things like Evernote and FireFox haven't been designed with that in mind.
There could have been an easy way, except there wasn't one built in historically and now it's not easy to add one, so there isn't an easy way and wont be in the near future, even though it would be nice if there was. Your best hope is a FireFox plugin and an Evernote update if enough people ask them.
