# Tree Style Tab contribution guide

If you are planning to open a new issue for a bug report or a feature request, or having additional information for an existing issue, or hoping to translate the language resource for your language, then please see this document before posting.

## Good, helpful bug reports

A good report is the fastest way to solve a problem.
Even if the problem is very clear for you, possibly unclear for me.
Unclear report can be left unfixed for long time.

Here is a list of typical questions I asked to existing reports:

 * **Does the problem appear with the [latest develpment build](http://piro.sakura.ne.jp/xul/xpi/nightly/)?**
   Possibly, problems you met has been resolved already.
   On Firefox 43 and later you need to set `xpinstall.signatures.required` to `false` via `about:config`, to try such unsigned packages of development builds.
   For Firefox 46 and later, you'll have to try an unbranded Firefox (including Beta, Aurora, and Nightly) to try development builds because the option will be removed on official Firefox 46 and later.
 * **Does the problem appear without Tab Mix Plus or something other tab related addon?**
   If a compatibility issue with other addons is reported without such information, it is very hard to be resolved.
   See also the next.
 * **Does the problem appear with a clean profile?**
   You can start Firefox with temporary clean profile by a command line `-profile`, like: `"C:\Program Filex (x86)\Mozilla Firefox\firefox.exe" -no-remote -profile "%Temp%\FirefoxTemporaryProfile"`
 * **Is the main topic single and clear?**
   Sometimes I got an issue including multiple topics, but such an issue is hard to be closed, then it often stays opened for long time and confuses me.
   If you have multiple topics, please report them as separate issues for each.

Then, please report the bug with these information:

 * **Detailed steps to reproduce the problem.** For example:
   1. Prepare Firefox version XX with plain profile.
   2. Install TST version XXXX.
   3. Install another addon XXXX version XXXX from "http://....".
   4. Click a button on the toolbar.
   5. ...
 * **Expected result.**
   If you have any screenshot or screencast, it will help me more.
 * **Actual result.**
   If you have any screenshot or screencast, it will help me more.
 * **Platform information.**
   If the problem appear on your multiple platforms, please list them.

## Feature requests can be tagged as "out of purpose"

Please see [the readme page](./README.md) before you post a new feature request.
Even if a requested feature is very useful, it is possibly rejected by the project policy.

Instead, please tell me other addon which provide the feature and report a new issue as "compatibility issue with the addon, TST should work together with it".
I'm very positive to make TST compatible to other addons.

## Translations, pull requests

If you've fixed a problem you met by your hand, then please send a pull request to me.

Translations also.
Pull requests are easy to merge, than sending ZIP files.
You'll do it without any local application - you can do it on the GitHub.
For example, if you hope to fix an exsiting typo in a locale, you just have to click the pencil button (with a tooltip "Edit this file") for a language resource file.
