As before grip the lid with all your force, using
whatever additional help may be needed tea towel,
rubber glove etc.

Then take hold of the jar in the other hand

And er, turn the jar.

You can always get a better grip on a glass jar simply
with the width of your hand, given which it seems to
make more sense to turn the jar rather than the lid.
Which still needs to be gripped firmly, but not turned
at the same time.

Use your left hand (if you're right handed). Apparently it's something to do with the muscle structure in your arms.
