abema.tv: breakage

List the website(s) you're having issues with:

https://abema.tv/now-on-air/abema-anime

What happens?

When watching videos, the memory usage increases, causing the website to become unresponsive.
Approximately 1GB is consumed in about 30 minutes, and after about an hour, the website freezes.

Your settings:

• OS/version: Windows10 Home 22H2
• Browser/version: Firefox 121.0
• Ad block extension/version: uBlock Origin 1.54.0

Other details:

||newrelic.com^$third-party
||nr-data.net^$third-party

The above two rules increase memory usage.

The following exclusion rules now work properly.

@@||js-agent.newrelic.com^$domain=abema.tv
@@||bam.nr-data.net^$xhr,domain=abema.tv

I can't rerpdocue with a short test (and not seeing nr-data.net request), how long it takes to see obvious abnormality? Did you test

||js-agent.newrelic.com^$script,redirect=noop.js,domain=abema.tv

? Please also attach screenshot(s) of task manager.

Memory usage exceeds 1GB in about 20 minutes and reaches 3GB in 40 minutes.

When I excluded the rule for||newrelic.com, I saw||nr-data.net.

If these two rules are excluded, memory usage seems to keep 200MB.

[Yuki2718]

Okay, reproduced though less degree. Will check the fixes lator. Meanwhile, can you check if

||trk.a-dsp.com^
||djuf7jb483wz1.cloudfront.net/p/l.jpg

can safely be blocked with your fixes applied?

[Yuki2718]

@chimaha Will add the exception only for ABP as not needed for AG or uBO with better fixes. BTW I found ads (CM) playing, but it's too sparse for me to check. Can you test

abema.tv##+js(json-prune, ads)

?

[hamachi25]

Are you referring to live broadcast ads (CM)?
I added that rule, but it doesn't seem to make any difference. Since it is a live broadcast, it would be difficult to avoid commercials.

[Yuki2718]

Ah, understood. Even if blocked, I only get blank screen while ads are playing so it doesn't make sense.

[hamachi25]

Not related to the issue, but is it possible to block CM with uBO?
It doesn't matter if the screen goes blank.
