# Garbage Collection You will see bugs that have been around for years and received very little activity, or bugs that were originally opened as means to track new features, but went out of scope as the overall direction of the project changed. Closing those bugs will help clean up our Bugzilla searches and keep things more organized. * Features request (RFE) that are outside our current or future scope. * Bugs that don’t apply anymore (E.g. old address book issues, UI that has been replaced). * Bugs left open with the intention of one day fixing it, but do not align with our scope. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://developer.thunderbird.net/thunderbird-development/fixing-a-bug/bug-triaging/garbage-collection.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
