Use a lower WebRTC mode on Firefox to hide private IP addresses
Releated issue:
- https://github.com/gorhill/uBlock/issues/3009

Firefox implements differently the behavior of `disable_non_proxied_udp`,
and this probably leads to more oft-misdiagnosed breakage.

Allow use of browser.storage.local as cache storage backend in Firefox
Related issue:
- https://github.com/uBlockOrigin/uBlock-issues/issues/409

By default `indexedDB` is used in Firefox for purpose of cache storage
backend.

This commit allows to force the use of `browser.storage.local` instead
as cache storage backend. For this to happen, set `cacheStorageAPI` to
`browser.storage.local` in advanced settings.

Additionally, should `indexedDB` not be available for whatever reason,
uBO will automatically fallback to `browser.storage.local`.

Refactor selfie generation into a more flexible persistence mechanism
The motivation is to address the higher peak memory usage at launch
time with 3rd-gen HNTrie when a selfie was present.

The selfie generation prior to this change was to collect all
filtering data into a single data structure, and then to serialize
that whole structure at once into storage (using JSON.stringify).

However, HNTrie serialization requires that a large UintArray32 be
converted into a plain JS array, which itslef would be indirectly
converted into a JSON string. This was the main reason why peak
memory usage would be higher at launch from selfie, since the JSON
string would need to be wholly unserialized into JS objects, which
themselves would need to be converted into more specialized data
structures (like that Uint32Array one).

The solution to lower peak memory usage at launch is to refactor
selfie generation to allow a more piecemeal approach: each filtering
component is given the ability to serialize itself rather than to be
forced to be embedded in the master selfie. With this approach, the
HNTrie buffer can now serialize to its own storage by converting the
buffer data directly into a string which can be directly sent to
storage. This avoiding expensive intermediate steps such as
converting into a JS array and then to a JSON string.

As part of the refactoring, there was also opportunistic code
upgrade to ES6 and Promise (eventually all of uBO's code will be
proper ES6).

Additionally, the polyfill to bring getBytesInUse() to Firefox has
been revisited to replace the rather expensive previous
implementation with an implementation with virtually no overhead.

Try to not rely on UA to lookup environment flavor
The environment flavor is used to by uBO to for self-configuration.

For users with spoofed UA at the `about:config` level, this might
cause uBO to misconfigure itself. Avoid UA and strictly rely on
browserInfo() for looking up environment parameters.

Reuse both flavors of webRequest wrapper in webext package
Related issue:
- https://github.com/uBlockOrigin/uBlock-issues/issues/407

Both flavors will be stitched together into a single
`vapi-qebrequest.js` file.

The decision of which flavor to use will be made at runtime,
according to the browser environment.

Harden content script's message Port against spurious disconnections
Those spurious disconnections have been observed to occur at
uBO's launch time.

Related issue:
- https://github.com/uBlockOrigin/uBlock-issues/issues/403

I have observed that this fixes an issue observed on Firefox 64
(current stable).

The reported Waterfox issue *may* be fixed as a result. If not,
the issue he still considered fixed as Waterfox is not
officially supported.

code review to further lower overhead of updating toolbar icon 2018-05-08 09:43:25 -04:00
Raymond Hill 89fd76ac39
use image data instead of paths for browser icons
When using paths, platform implementations of setIcon typically
will fetch the resource then convert to image data internally.
It is preferable for uBO to do this conversion itself as it can
be done only once at launch time.

With chromium-based browsers, using image data eliminate the
incessant network traffic to fetch browser icons as reported
in the extension's dev tool, meaning a good chunk of overhead
is eliminated.

Also, use optimal icon sizes, as of now both chromium and firefox
prefers 16px instead of 19px, and 32px instead of 38px.

Rob Wu b27f23d520 Clear return value of vapi.js content script (#3721)
Upon start-up, uBlock runs all content scripts in manifest.json using
`chrome.tabs.executeScript`. When this API is used, the value of the
last expression is automatically cloned and transferred to the
callback of `chrome.tabs.executeScript`. This is convenient if needed,
and a performance burden otherwise (the latter is the case for uBlock).

There are three content scripts that need to be checked:

- vapi.js
  The last expression is often the vAPI object, and it is relatively
  expensive to clone this object. This commit sets the value of the
  last expression to `void 0` to solve this inefficiency.

- vapi-client.js
  No action needed yet; The last expression is `vAPI.shutdown.add(...)`,
  which has a void return value.

- contentscript.js
  No action needed yet; The last expression is an immediately-invoked
  function expression without return value.
