I am still able to reproduce Assertion failure: aReason == ContentBlockingNotifier::eOpenerAfterUserInteraction, at src/toolkit/components/antitracking/ContentBlocking.cpp:321

Severity: -- → S3
Priority: -- → P2

I cannot reproduce the issue with the latest Nightly build by the test case.

Tyson, Are you still able to reproduce the issue that you mentioned in comment 5. If you do, could you provide the test case? Thanks.

Flags: needinfo?(twsmith)

Yes I am able to reproduce the issue with the attached test case and the instructions in the description. Note that the test case calls FuzzingFunctions.memoryPressure() which requires a fuzzing build. Also this test case is not 100% reliable but usually triggers within 10 attempts. The instructions account for this.

An updated Pernosco session is available here: https://pernos.co/debug/UfvAbNuMMhAfaH6azWh-jA/index.html

Smaller test case that does not require FuzzingFunctions.

Tim does this new test case work for you?

I opened the link with my local Nightly build on Mac but still cannot reproduce the issue.

Are there any prerequisite steps before opening the test case link?

Attached file prefs.js —

I am able to reproduce it reliably with grizzly.

Here is a prefs.js file that grizzly generates if you are trying to reproduce the issue without grizzly.

Is the Pernosco session sufficient to debug the issue?

Yeah, a Pernosco session would be helpful to debug this issue.

(In reply to Tim Huang[:timhuang] from comment #12)

Yeah, a Pernosco session would be helpful to debug this issue.

See comment 2 and comment 7. If those don't provide the relevant information please let me know.
