Hi wb666greene
No- your issue looks different. Mine is more of a dev/design question


There are no current plans to remove it.


Indeed, I suspect that Mozilla have slightly jumped the gun on this. Their recommendation is to replace them with webworkers but this is a whole level of complexity higher than the appcache.

There is another thread somewhere where I tested some performance issues - appcache makes a massive difference to the performance of Dashboard UI's largely because of the extreme size of Angular. It also gives a nice boost to uibuilder too.
