adfilt

What do you mean by this? All the filters in adflit?

I'm not very knowledgeable about Brave, but it feels a bit odd that a filterlist would crash the browser. Have you tried disabling all custom filters and seeing if it persists?

[DandelionSprout]

How do the crashes occur? Is it just the tab that closes/crashes, or does the entire browser close?

@iam-py-test Sorry for not specifying the one I'm using! It's https://raw.githubusercontent.com/DandelionSprout/adfilt/master/ClearURLs%20for%20uBo/clear_urls_uboified.txt

@DandelionSprout

No matter how many tabs or windows are open, brave crashes completely and closes everything without any error or notification, when I disable this filter specifically, opening youtu.be links work as intended.

It's https://raw.githubusercontent.com/DandelionSprout/adfilt/master/ClearURLs%20for%20uBo/clear_urls_uboified.txt

That makes a bit more sense (although the fact that a filterlist can crash the browser still feels like a browser bug). The "ClearURLs for uBo" is just the ClearURLs rules converted into a filterlist specially for uBlock Origin (and AdGuard). The conversion script is not flawless, the list will still have any issues from the ClearURLs list (which is known to break websites and gets very little maintenance), and was never designed for (or tested in) Brave's adblocker. I would not recommend use of this list. Oddly, I don't see any youtu.be rules in that list though, and only 4 fairly normal rules for youtube.com. I suspect that maybe one of the global rules (maybe a regex?) is applying to that URL and Brave doesn't like it (but that's just speculation). I will try to get a virtual machine setup with Brave and test some time this week

Brave added support for removeparam recently but not everything works yet, for example: https://github.com/brave/adblock-rust/issues/246 https://github.com/brave/adblock-rust/issues/245

Also could be related to this https://github.com/brave/adblock-rust/issues/248 ? If so, you'll need to wait for update.

[iam-py-test]

Thank you @Nojuuu I don't have time to look into this, but that sounds likely @Shutruk the best solution is probably to disable the ClearURLs for uBo for now, and wait for the fix from Brave to be available

[Shutruk]

Thanks for the help, I will disable it then till a fix is available.

[Nojuuu]

Fix should be available now: https://github.com/brave/brave-browser/releases/tag/v1.47.186

[iam-py-test]

@Shutruk can you confirm that there are no issues on the fixed Brave version? If not, then I can install Brave on a VM and look into what ClearURLs for uBo is doing wrong

[Shutruk]

@iam-py-test no more crashes happened after 1.47.186, the issue seems to be fixed.
