abctx is a free Google Chrome extension developed by jtlo. It falls under the category of Browsers and is specifically categorized as an Add-ons & Tools subcategory. This extension provides a convenient bookmarking feature that allows users to associate bookmarks with specific URL patterns.

With abctx, users can register bookmarks that will only appear when the current browsing URL matches the registered patterns. This functionality is particularly useful for storing domain-specific bookmarks. For example, users can bookmark wiki pages on a wiki site, even if the wiki system itself does not support bookmarking. These bookmarked wiki pages will only appear when accessing the wiki site, eliminating the need for additional space on the bookmark bar.

abctx offers a simple and intuitive solution for managing domain-specific bookmarks, enhancing the browsing experience for users who frequently visit specific websites. This extension is a valuable tool for organizing and accessing relevant content within the Chrome browser.
