[Call Stacks In Crash Reports] Redaction Levels

[issackjohn]

We need to discuss the appropriate level of redaction for extension frames in call stacks.

There are three potential options to consider:

• Full redaction
• Per-frame redaction
• No redaction for the main world

Discussion Points:

• Is full redaction necessary, or can we consider per-frame redaction?
• Should there be no redaction for the main world?

There was a rough consensus in the WebPerfWG that extension content was acceptable if it appeared in a place (main world) where it could be on the stack.

Must be a permissions issue but I can't add appropriate labels to the issue

It seems like per-frame redaction is the best path. That gives signal that there is a problem occurring that interacts with an extension, without exposing what or how.

Lack of a stack entirely feels like it could lead to a lot of issues in trying to interpret what's happening - Were we unable to get a stack? Did the page's processing pipeline drop the stack? Only redact the relevant frames gives something for the site owner to aggregate one instead of having a large "blank" bucket.
