## Description

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.

## Review summary

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.
