Description

Mozilla has an experimental feature for saving the "wireframes" for web pages a user visits. I.e. a simplified rectangly version of the page, which would be used for tab content when a page is loading or for tab previews.

This is currently behind browser.history.collectWireframes, which is still off upstream.

Once this feature is fully developed, we should make sure that disk caching is off for private browsing (probably will be). We should also consider whether to keep this off for non-private browsing as well, similar to how we disable thumbnail caching in both modes: #41595 (closed).

To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
