If you want to ask a question, please check out the wiki. If you don't find an answer there, ask on IRC (#sway on irc.freenode.net). The issue tracker may not be used for questions.
Additionally, problems with Firefox are almost certainly Firefox bugs, not sway bugs. Start by submitting your issue to the Firefox Bugzilla and come back here only after they confirm otherwise.
Otherwise, please include the following four components in your bug report: sway version, debug log, configuration (if applicable), and an explanation of steps taken to reproduce the issue. If sway crashes, also include a stack trace.
This will record information about sway's activity when it's running. Briefly reproduce your problem and exit sway. When preparing a debug log, brevity is important - start up sway, do the minimum work necessary to reproduce the error, then close sway.
Upload the debug log to a pastebin service such as [gist.github.com](https://gist.github.com), and link to it below.
* Debug Log:
You should try to reproduce the issue with the default configuration. If you cannot, please reproduce with a minimal configuration, upload the config to a pastebin service, and link to it below.
* Configuration File:
Finally, explain the steps you took in plain English to reproduce the problem below.
If the lines mentioning sway/wlroots have "??" for the location, your binaries were built without debug symbols, and the stack trace is unlikely to be useful. You can find instructions to compile sway from source [here](https://github.com/swaywm/sway/wiki/Development-Setup#compiling-as-a-subproject). Note that debug symbols are included in Meson builds by default.
