Checking the message name (and connectorId) is mandatory for Safari,
because when the background page sends a response back to a document,
then all the frames in its owner tab will receive the exact same
message, which could confuse the script in some cases.
The beforeNavigate event wasn't reliable (sometimes didn't fire, sometimes
fired unnecessary when opening a link with the middle click - which had a
workaround previously, but that's also removed by this commit).
When the event didn't fire, the bindTabToPageStats method didn't run,
and the requests related to the tab weren't blocked.
Safari's extension API doesn't provide a way to intercept requests
initiated by plugins, so those cases need special care (or at least the
popular sites).
This commit adds a new JS file (sitepatch-safari.js), which will store the
patches (if it's possible to create one) for specific sites.
As an example, this commit includes a technique for removing in-video ads
from YouTube videos.
It works similarly to the xhr intercepting, except here the window.open
global function is being overridden.
Note that it could only work if the site's Content Security Policy allows
inline scripts, and the script on the webpage doesn't have a copy of the
original window.open function (it can happen only if the page has an
inline script in its head element, where the reference to the original
function can be obtained - likely this cannot be prevented in Safari).
- Add script injection to vAPI, plus a raw implementation for Safari
(element-picker.js requires it)
- Tweak element picker to work with Safari
- Revert a change from previous commit: element-picker.js' background
message handler (since actually it can have its own messaging channel)
- Don't send "undefined" reponses from background to content
Earlier, a technique was used to open the extension's Options page when
the user clicked a checkbox input at Safari's extension settings. The method was removed because:
- the Options page can be opened via the extension's toolbar button (which
cannot be disabled in Safari, so it will be there all the time);
- involved more clicks than opening from the toolbar button;
- the string beside the checkbox couldn't be localized.
- Update assets from gorhill/uBlock/master
- Remove whitespace from element-picker.js
- Simplify code in profiler.js (btw, Date is still needed as fallback
for older browsers)
- Clarification for Safari's storage where the QUOTA_BYTES came from
