Features & Capabilities

The TST Bookmarks Subpanel is a Chrome extension designed to integrate a bookmarks subpanel within the popular Tree Style Tab sidebar. Since the Tree Style Tab addon has become a sidebar panel itself, it limits the use of other sidebar panels simultaneously, such as bookmarks. This extension resolves that by embedding bookmarks below tabs as a subpanel, allowing simultaneous access.

While it replicates Firefox's native bookmarks sidebar panel, certain WebExtensions API restrictions apply. For instance, it cannot open non-regular URLs like about:config, and drag-and-drop support outside of Tree Style Tab's sidebar is limited. Additionally, all bookmarks display a uniform icon due to API constraints. This addon enhances productivity and browsing organization for users relying on Tree Style Tab in Firefox contexts.

ブックマークを追加すると、追加したサイトが別ウインドウで開いてしまいます。仕様でしょうか？

Please - add ability to change F2 hotkey to user defined hotkey. Developing in cloud IDE need that hotkey for their options.

Is TST Bookmarks Subpanel Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

TST Bookmarks Subpanel requires very minimum permissions.

Risk impact analysis details

Medium Access to bookmarks may provide insights into user preferences and interests but generally carries low risk.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

TST Bookmarks Subpanel has earned a fairly good reputation and likely can be trusted.
