If you are extensions developer you have to do a lot of repetitive actions during the process.

This extension can help you quick reload all your unpacked extensions with a keyboard shortcut or from context menu.

 

Pros:

• Quick reload with context menu or shortcut (Alt-Z by default but you can change. See Options page for instructions)
• Reload only enabled extensions
• If Options page is open also restart it
• Ability to reload active tab (see Options page). It useful for content script extensions development.
• Ability to turn off reload from context menu (see Options page)

Contras:

• It closes the background debugger window. No public API to reopen(restart) 🙁
