Issue
In my Browser Extension app, I've noticed discrepancies in the Crash Free Sessions and Users metrics. What might be contributing to this issue?

Users using Sentry within a Browser Extension
Resolution
From our Shared Environments / Browser Extensions docs, errors that occur within browser extensions must be manually captured. Because of this, errors are not automatically detected, and metrics like Crash Free Sessions and Crash Free Users may appear inaccurate. This is because, once errors are manually captured, they are considered handled by Sentry. Only unhandled errors affect Crash Free metrics, so manually captured errors do not impact Crash Free Sessions or Users percentages.
