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.
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.
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"`
## Please don't join to an existing discussion if your problem is different from the originally reported one
Even if the result is quite similar, they may be different problem if the reproduction steps for yours are different from the one originally reported.
Then, you should create a new issue for yours, instead of adding comment to the existing issue.
Otherwise, I'll be confused if the original reporter said "the issue is a compatibility issue with another addon" but another reporter said "I saw this problem without any other addon".
To avoid such a confusion, please post your report with detailed reproduction steps always.
## 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".
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.
