1903396 - WebExtension / port.postMessage Memory Leak

Status: UNCONFIRMED

(GeckoView :: Extensions, defect, P3)

Description

[Matt]

Steps to reproduce:

I created a test app which loads up GeckoView, and installs a simple content script extension which passes stringified JSON data back and forth from Kotlin to a webpage whose files exist locally on the Android device. After some time, memory usage will gradually increase and the app will crash. I have tried using a background script as well but that does not fix the issue.

I call port.postMessage() with the stringified JSON data every 5-10 seconds. As a result, memory will gradually climb over time, and seems to crash at around the 8-12 hour mark.

Actual results:

Memory will rise and garbage collector will run but not free up all memory, and Geckoview will consume so much memory that the application crashes.

Expected results:

GeckoView should not leak memory and not crash.
