Cosmetic Exception filter disabling?

[nick-n-dev]

Prerequisites

• I verified that this is not a filter issue
  • Filter issues MUST be reported at filter issue tracker
• This is not a support issue or a question
  • Support issues and questions are handled at /r/uBlockOrigin
• I performed a cursory search of the issue tracker to avoid opening a duplicate issue
  • Your issue may already be reported.
• I tried to reproduce the issue when...
  • uBlock Origin is the only extension
  • uBlock Origin with default lists/settings
  • using a new, unmodified browser profile
• I am running the latest version of uBlock Origin
• I checked the documentation to understand that the issue I report is not a normal behavior

Description

I am aware of important/badfilter etc for static filters, however none of that seems to apply to cosmetic filters.

As an example: a 3rd party filters list adds an exception rule of the form '#@##'
Now there seems to be nothing i can do on my side to disable/override that, adding the same rule without '@' has no effect.
Obviously dynamic filtering is not an option.

I believe anything in "My Filters" should trump EVERYTHING else, otherwise its purpose is somewhat...limited.

Expected behavior:

Exception in 3rd party list is ignored/overriden by locally defined filter.

Actual behavior:

Locally defined filter is overriden by 3rd party.

Your environment

then append a invalid element token such as important after the element. eg ##[selector],important

Could you please clarify what you mean? i have already tried adding ,important after the element, and it changed nothing.

Exception in 3rd party list is ignored/overriden by locally defined filter.

Post a specific example, the vague description does not help.

[nick-n-dev]

Ok, so:

say a 3rd party filterlist (adguard/easylist for example) have a filter such as: somewebsite.com#@##subscribe-button in their list.

But i dont want to actually see that element, so i go to my filters, and i add: somewebsite.com###subscribe-button

Nothing changes, and the log shows it's still being filtered, i tried: somewebsite.com###subscribe-button,important
but that also did nothing.

I hope that's clear enough :)
I would really prefer not to have to disable a whole list (and a pretty important one to me) just for 1 line...

i tried: somewebsite.com###subscribe-button,important
but that also did nothing.

What did the logger show this time ? and post the filter which was shown here.

[nick-n-dev]

Not sure what i should copy/paste so i'll just stick a couple screenshots here:

What it looks like in "My Filters"

As per the second screenshot, your filter is getting applied and I just tested this on my setup with Fanboy Annoyance/Social activated on a youtube channel and it works as expected.

youtube.com###subscribe-button,important helps bypass the exception(#@##) filter and successfully hides the Subscribe button for e.g https://www.youtube.com/channel/UCPD_bxCRGpmmeQcbe2kpPaA

Make sure all other extensions are disabled when you're testing.

[nick-n-dev]

You're right,
not sure what was causing the button to stay (it does seem to be working after refreshing firefox).
I just saw the yellow-highlighted entry in the log and assumed the local filter was being ignored, my bad.

Thank you for the help though, very much appreciated.

This doesn't happen if you added ###subscribe-button,important via Picker. Anyways, next time provide full Steps To Reproduce and if you can't do that, then post the issue on reddit, which is the dedicated help section, while GitHub is only for provable issues with details Steps To Reproduce along with filling the entire template as asked.

To enforce disabled filter via #@# try:

youtube.com###subscribe-button#subscribe-button

• based on Cosmetic filter does not work if exception for this filter or filter with negated domain exist in other list #388 (comment)

Idea with add ,important to comsetic filters can misleading this (for network filters):

https://github.com/gorhill/uBlock/wiki/Static-filter-syntax#badfilter

The chance of a html element:

<important> 
    blah blah blah blah 
</important>

being present in the Internet is probably close to zero.

I've encountered a similiar issue, I've found and added a third-party filter list which has turned out to contain several bad/unwanted cosmetic generic filters which break some sites: ##.ads, ##div[class*="ads"]. Now, there seems to be no way to disable ##.ads without disabling similiar filters on other filter lists (for example EasyList)

Isn't that what ghide is for?

Well if a list contains "several bad/unwanted cosmetic generic filters" causing you issue, then it's a low quality list which you should not subscribe to -- that's the solution.
