About TinyJSD

Note: due to the massive and rapid changes in the Mozilla Platform, TinyJSD is no longer actively maintained. The last version supports Thunderbird 60/SeaMonkey 2.57. We recommend to use the standard Developer Tools that are shipped with Thunderbird.

TinyJSD is a JavaScript debugger for Mozilla products that support non-Webextension-type addons (Thunderbird, SeaMonkey). The key differences to debuggers like the debugger built into Thunderbird are:
focused on debugging privileged code such as extensions and the application itself
simple user interface for easier use than complex debugger tools

Main Features

• Setting of breakpoints
• Step by step execution of the code
• Inspection and modification of variables
• Execution of arbitrary code while debugging
• Launching the debugger as during the startup, allowing to (partially) debug the startup phase of the application.
• Breakpoints, Watchlist items and contents of scratchpad are saved between debugging sessions.

Downloads

TinyJSD is now available on Mozilla Addons.
