# Submitting issues **Must read:** [How to Report Bugs Effectively](http://www.chiark.greenend.org.uk/~sgtatham/bugs.html). ### Before you submit 1. Submit **bugs/issues only**. - Bugs occur, I will fix them. 1. Do **NOT**: - Submit design ideas. - Submit feature requests. - Submit "revolutionary ideas". - Use issues as replacement for threads on a bulletin board. - Any such issue will be closed without comment. 1. Make sure your issue [hasn't already been fixed in a recent release](https://github.com/gorhill/uBlock/releases). 1. Verify that the issue does **not** occur with uBlock disabled. - If it still occurs with uBlock disabled, it's probably not an issue with uBlock. 1. Verify that the issue is not related to a 3rd-party filter lists. - If it is the case, report to the list maintainer(s). - It helps to also test with Adblock Plus, with **same** filter lists. - If issue also occurs with ABP, it's most likely a filter list issue. 1. Any issue opened with no effort to provide the required details will be closed without comment. --- ### What to include To help diagnose and fix the bug/issue, please always, **always**, **ALWAYS** include the following in your report: * A clear list of steps to reproduce the problem * **Always include a URL**, _even_ if "it happens everywhere". Just do it. * Symptoms of the issue * Describe what you observe and consider broken behavior; this is what we'll be looking for after executing the steps * Example: video doesn't start playing, page layout broken * A screenshot of **any** of uBlock's preferences that differ from the defaults * This includes a whitelisted website, enabled/disabled filter list, anything * Please do include everything different from the defaults whether or not it seems relevant to your issue * The version of uBlock you're having the issue with; you can find this in [uBlock's popup UI](https://github.com/gorhill/uBlock/wiki/Quick-guide:-popup-user-interface) * Example: `uBlock 0.9.0.0` * The browser you're using and its version * Examples: `Firefox 36`, `Chrome 41.0.2272` * The OS you're using and its version * Examples: `Windows 8.1`, `Linux Mint 17.1` * A list of other extensions you have installed * Tip: try disabling them and see if your issue still occurs Otherwise, we've noticed that a lot of **your** time (and the developers') gets thrown away on exchanging back and forth to get this information.
