Topmarks is now Mr. Newtabby. New name, new icon, same add-on — your bookmarks, settings, and saved tab groups carry over untouched, and updates keep arriving automatically.

Bookmark favicons now actually load on Firefox: icons are remembered locally from the tabs you open (no network, no third-party services) instead of relying on a favicon cache Firefox doesn't expose to extensions. Plus a friendlier Groups menu — forgetting a saved group is now a direct two-click action instead of a submenu, and Topmarks detects and lets you re-grant the tab permissions if the browser has dropped them.

New: Tab groups. Reopen your closed browser tab groups straight from the bookmarks bar. Fully opt-in — Topmarks requests the tabs and tab-groups permissions only when you enable the feature in Settings, and your groups are saved locally, never uploaded.

New search field option added + small style tweaks.

Overflow chevron, dropdown flip on viewport overflow, exponential backoff for Unsplash failures, wallpaper-error UI in settings, and various polish.
