Features & Capabilities

Tabloc is a Chrome extension designed to enhance your browsing workflow by adding a convenient "Lock Tab" button. When a tab is locked, any links you click within it will open in new tabs instead of overwriting the current tab. This feature allows you to preserve important tabs and multitask more effectively.

The extension offers flexible customization options including opening new tabs in the background or foreground, choosing the position of new tabs (next to the current tab or at the rightmost end), excluding in-page links or form submissions from triggering new tabs, setting automatic lock for tabs with specific URLs, and selecting different "Lock Tab" button icons. These features make Tabloc an essential tool for users looking to optimize tab management and maintain their browsing flow efficiently.

User Reviews

Tabloc is praised for giving users control over tabs by locking/pinning them, with support for explicit URLs or regex and site-based rules. Reviewers say it makes workflow smoother by keeping dashboards open and reducing back/middle-clicks, and they like its minimalist design. However, several reviews note locks aren’t persistent across reloads or restarts and point to compatibility issues on some Firefox versions (e.g., 124). Some UI concerns exist about lock-icon visibility and a distracting padlock emoji. Overall, it’s a useful enhancement with occasional reliability and UX drawbacks and clear requests for stronger persistence.

Pros

Auto-lock/pin of tabs via explicit URLs or regex to keep important tabs stable.
Keeps dashboards/pinned tabs open, reducing the need to navigate back or manually open links.
Site-aware behavior: opens links in new tabs per site preferences for locked tabs and supports regex.
Minimalist design that users find easy to adopt and integrate into their workflow.
Regarded as an essential, useful extension for tab management.

Cons

Lock state and settings can be lost on page reload or browser restart.
Compatibility issues with some Firefox versions (e.g., 124) causing it not to work for some users.
UI visibility of the lock icon is poor on dark themes and the padlock emoji can be distracting.

Recent reviews

Win7/Firefox 115 ESR. I found I missed the extension on new installs. Give a useful tab indication. Would be nice if it prevented tab closure as well or remove the tab's X.

Is Tabloc 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.

Tabloc requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

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.

Tabloc has earned a fairly good reputation and likely can be trusted.
