With the new csstree-based parser, it should now be
safe to parse `-abp-has` as declarative. There are over
a hundred such cosmetic filters in EasyList, and we want
to have these filters declaratively enforced whenever
possible in order to let the browser do the work natively
rather than rely on JS code.
The addition of those scriptlets will help uBOL to properly
filter more anti-blocker mechanisms on various site and also prevents
popups on many sites.
Also, fixed properly injecting scriptlets in embedded frames -- it
turns out I misunderstood the `allFrames` settings in the `scripting`
API.
Fixed trusted sites not being excluded from declarative
scripting.
Assign "uBOL_"-prefixed name to anonymous scripting functions
so that they can be easily found in performance profiler results
in dev tools.
Imrpove spread of chunks of filters across declarative scripting
files.
This solves the following remaining issues regarding specific cosmetic
filtering:
- High rate of false positives in last build
- High number of generated content css files in the package
First iteration of adding scriptlet support. As with cosmetic
filtering, scriptlet niijection occurs only on sites for which
uBO Lite was granted extended permissions.
At the moment, only three scriptlets are supported:
- abort-current-script
- json-prune
- set-constant
More will be added in the future.
