Hello Hans
Unfortunately we don't have a solution for this problem. The key storage of Mailvelope is totally isolated and access for a web application is only possible in a very limited way. Which is by design an actually a key feature.
Although we might check the availability of certain keys from within Roundcube and providing a backup copy from the Roundcube side is theoretically possible, it doesn't make much sense because it would break the integrity of the key store by moving sensitive data (like private keys) from the extension's isolated storage into the web application's local storage which cannot be trusted.
An immediate workaround might be to switch to Chrome where the storage backend for extensions seems to be more reliable. But other than that, you have to wait for Firefox to fix that issue.
Best, Thomas
P.S. check out the latest version from our dev-mailvelope branch. It comes with an import feature for public keys if they're missing for certain message recipients.

Dear RC-devs,
A question that is probably outside of your area of influence but nonetheless I'm interested if you have had any more feedback on this. If you don't then a short "no" would ofcourse be very much acceptable.
Recently on the ML it was announced that you were looking into more functional integration with Mailvelope, that sounds very promising, however Mailvelope (at least on Firefox) suffers from a very problematic bug, namely it frequently looses all keys and settings due to some unreliable behaviour of the extension storage back end in firefox: https://bugzilla.mozilla.org/show_bug.cgi?id=1091244
And: https://github.com/mailvelope/mailvelope/issues/304
There are a number of tickets opened in the Mailvelope Github, however no usable remedy has been found yet. Do you know of any way to solve/work around this? As it is effectively prohibiting me from using Mailvelope at all.
Best regards, Hans de Raad
