Is there any reason an add-on my automatically be disabled on some machines

I recently released a new version of an add-on and I have some users reporting that the add-on occasionally disappears. When they look in about:debugging it has no Internal UUID or Manifest URL.

There are some details here: https://github.com/birtles/rikaichamp/issues/444

Are these any reasons why an add-on might just disappear like that? For example, if the background script consumes too much memory, could it be killed?

(The newer version of the add-on does use more memory in the background script than the previous version, but much less than it did a few months ago.)

Thanks for the report, @birtles! A couple of engineers are following the issue on your repo in case other folks can provide more info.

Thank you @caitlin! You’re the best!
