TrelloHelper автор Code-One

Trello Link Redirect intercepts top-level HTTPS navigations to trello.com and www.trello.com. It classifies each URL as a card link (/c/...), board link (/b/...), or another Trello page, then applies the user's configured rule.

By default, card and board links are sent to the desktop app, while other Trello pages stay in Firefox. The feature is intended for systems where the Trello desktop application is installed. Without the desktop app, external links may not open as expected. The extension preserves the original path, query string, and fragment by replacing only the https:// scheme with trello://. The installed desktop app must support the resulting URL format. Firefox usually asks for permission the first time an external Trello link is opened.


Click the TrelloHelper toolbar button to enable or disable automatic redirection. The ON or OFF badge indicates the current state. Right-click the toolbar button and choose Open TrelloHelper settings… to configure the Link Redirect feature.

The settings page lets you:

• Enable or disable automatic redirection.
• Choose whether card links should open in the desktop app.
• Choose whether board links should open in the desktop app.
• Choose whether other Trello pages should open in the desktop app or remain in Firefox.
• Close the original Firefox tab after Firefox loses focus, with a short safeguard delay.

Preferences are saved locally using browser.storage.local. The extension does not send preferences or browsing data to an external server.

• Only top-level navigations to https://trello.com/* and https://www.trello.com/* are intercepted.
• The focus-based tab-closing option detects whether Firefox has lost focus. It cannot confirm that Trello itself successfully opened or received focus.
• The extension retains the current URL conversion method (https:// to trello://). Support for specific URL formats depends on the installed Trello desktop app.
