Tab Shelf 2025.2.1 is now available on the Chrome Web Store! At the timing of writing, it is still awaiting review on the Edge Extensions Store. Version 2025.2.0 was ultimately not released due to a bug discovered midway through the review period.
This release includes these headlining changes:
- Expanded duplicate tab handling. Detect-only will remain the default behaviour, but you can now choose to have duplicate tabs deleted (either if it’s a duplicate in the context of just the same window, or across your entire session), or do nothing (more performant).
- A more prominent Compact mode. Previously this was misleading hidden behind the ‘Hide tab URLs’ option). Window and tab group headers will also now appear more compact when compact mode is enabled.
- Overhauled, more predictable drag-and-drop behaviour. Previously it wasn’t clear if a tab is supposed to be moved above or below the tab it’s dropped over.
- A refreshed design for tab groups. This redesign gives tab groups a more ‘contained’ appearance to better represent how the tabs are grouped. A footer with buttons to add a new tab to the group or scroll to the top of the group have also been added. It also makes for a convenient drop target to drop a tab to append it to a group. The somewhat controversial signature thick outline can also be disabled now.
- Optimizations for other browsers can be enabled via Settings. This provides accomodations for Vivaldi and Brave users who previously found that the default New Tab page URL led to a blank page.
Aside from these headline features, various other performance and behavioral fixes have been included in this release. You can read the full changelog for 2025.2.0 and 2025.2.1.
