uBlockOrigin/uAssets#22556
All supported browsers now have the concept of priviledged pages, there is no need for these extra trusted-site directives. Related issue: uBlockOrigin/uBlock-issues#3101
Context: element picker Related issue: uBlockOrigin/uBlock-issues#3142
In uBO, the "cache storage" is used to save resources which can be safely discarded, though at the cost of having to fetch or recompute them again. Extension storage (browser.storage.local) is now always used as cache storage backend. This has always been the default for Chromium-based browsers. For Firefox-based browsers, IndexedDB was used as backend for cache storage, with fallback to extension storage when using Firefox in private mode by default. Extension storage is reliable since it works in all contexts, though it may not be the most performant one. To speed-up loading of resources from extension storage, uBO will now make use of Cache API storage, which will mirror content of key assets saved to extension storage. Typically loading resources from Cache API is faster than loading the same resources from the extension storage. Only resources which must be loaded in memory as fast as possible will make use of the Cache API storage layered on top of the extension storage. Compiled filter lists and memory snapshot of filtering engines (aka "selfies") will be mirrored to the Cache API storage, since these must be loaded into memory as fast as possible, and reloading filter lists from their compiled counterpart is a common operation. This new design makes it now seamless to work in permanent private mode for Firefox-based browsers, since extension storage now always contains cache-related assets. Support for IndexedDB is removed for the time being, except to support migration of cached assets the first time uBO runs with the new cache storage design. In order to easily support all choices of storage, a new serializer has been introduced, which is capable of serializing/deserializing structure-cloneable data to/from a JS string. Because of this new serializer, JS data structures can be stored directly from their native representation, and deserialized directly to their native representation from uBO's point of view, since the serialization occurs (if needed) only at the storage interface level. This new serializer simplifies many code paths where data structures such as Set, Map, TypedArray, RegExp, etc. had to be converted in a disparate manner to be able to persist them to extension storage. The new serializer supports workers and LZ4 compression. These can be configured through advanced settings. With this new layered design, it's possible to introduce more storage layers if measured as beneficial (i.e. maybe browser.storage.session) References: - https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/API/storage/local - https://developer.mozilla.org/en-US/docs/Web/API/Cache - https://developer.mozilla.org/en-US/docs/Web/API/Web_Workers_API/Structured_clone_algorithm

Related to new cache storage code.
Turns out it's currently the fastest among the three currently implemented (Cache, browser.storage.session, indexedDB). Possibly because indexedDB can natively persist structure-cloneable data, something uBO can now benefit with the work on abstracting away the limitations of various storages being limited to persist only text or JSON data.

`webext.js` module needs to be explicitly imported. Added time-based heuristic to decide when a webpage loses communication with background process.
