问题
Using Firefox 24.0 on Ubuntu 12.04, I can reproduce this by:
- Going to http://cytoscape.github.io/cytoscape.js/ with Firefox
- Use Ctrl + + or Ctrl + - to zoom in or out
- Move the mouse over the graph in the corner and watch it disappear.
Seems to work fine in Chrome. Any ideas on how to fix this?

The same version of Firefox on Mac does not have this issue, leading me to believe this is a Firefox problem or an Ubuntu problem. If I were you, I would file a bug report with Mozilla: https://bugzilla.mozilla.org
They can investigate whether this is an issue on their end or whether this is an issue on the Ubuntu end. -M

I think I have a solution. In Firefox if you press ctrl-0, it will reset your zoom level to default. This appears to solve the bug in Firefox 24 and 25. If you then press Ctrl and + or - to zoom in or out, the disappearing behavior will return. You can resolve again by resetting to default zoom level.
Not ideal behavior, but this is probably either a Firefox bug or a cytoscape.js bug.
