The new parser no longer uses the browser DOM to validate that a cosmetic filter is valid or not, this is now done through a JS library, CSSTree. This means filter list authors will have to be more careful to ensure that a cosmetic filter is really valid, as there is no more guarantee that a cosmetic filter which works for a given browser/version will still work properly on another browser, or different version of the same browser. This change has become necessary because of many reasons, one of them being the flakiness of the previous parser as exposed by many issues lately: - https://github.com/uBlockOrigin/uBlock-issues/issues/2262 - https://github.com/uBlockOrigin/uBlock-issues/issues/2228 The new parser introduces breaking changes, there was no way to do otherwise. Some current procedural cosmetic filters will be shown as invalid with this change. This occurs because the CSSTree library gets confused with some syntax which was previously allowed by the previous parser because it was more permissive. Mainly the issue is with the arguments passed to some procedural cosmetic filters, and these issues can be solved as follow: Use quotes around the argument. You can use either single or double-quotes, whichever is most convenient. If your argument contains a single quote, use double-quotes, and vice versa. Additionally, try to escape a quote inside an argument using backslash. THis may work, but if not, use quotes around the argument. When the parser encounter quotes around an argument, it will discard them before trying to process the argument, same with escaped quotes inside the argument. Examples: Breakage: ...##^script:has-text(toscr') Fix: ...##^script:has-text(toscr\') Breakage: ...##:xpath(//*[contains(text(),"VPN")]):upward(2) Fix: ...##:xpath('//*[contains(text(),"VPN")]'):upward(2) There are not many filters which break in the default set of filter lists, so this should be workable for default lists. Unfortunately those fixes will break the filter for previous versions of uBO since these to not deal with quoted argument. In such case, it may be necessary to keep the previous filter, which will be discarded as broken on newer version of uBO. THis was a necessary change as the old parser was becoming more and more flaky after being constantly patched for new cases arising, The new parser should be far more robust and stay robist through expanding procedural cosmetic filter syntax. Additionally, in the MV3 version, filters are pre-compiled using a Nodejs script, i.e. outside the browser, so validating cosmetic filters using a live DOM no longer made sense. This new parser will have to be tested throughly before stable release.
