v1.0 – Initial Release

Basic popup UI to enter a custom title for the active tab.

Title applied immediately via document.title injection.

Titles persisted only until tab reload; lost on browser restart.


v2.0 – Storage Integration

Added storage.local to save custom titles keyed by tab ID.

Titles reapplied automatically when a tab reloads.

Cleanup logic removes stored titles when a tab is closed.

Limitation: titles did not survive browser restarts (tab IDs change).


v3.0 – Domain-Based Persistence

Switched storage from tab ID → domain name.

Titles now persist across browser restarts and PC shutdowns.

Any page on the same domain inherits the saved custom title.

Popup updated to show current domain and saved title.


v3.5 – AMO Compliance Updates

Added browser_specific_settings.gecko block with unique add‑on ID.

Declared data_collection_permissions with collects_data: false and required: ["none"].

Fixed validation errors for AMO submission.


v4.0 – Content Script Enforcement

Introduced content-script.js running at document_start.

Overrides document.title setter to prevent sites from overwriting custom titles.

Ensures <title> element stays locked to the saved value.

Eliminated need to refresh after restart — titles now apply instantly and persistently.

Popup UI enhanced with “Remove saved title” option.


v4.1 – Manifest Compatibility Fix

Updated strict_min_version to 142.0 to align with Firefox’s support for data_collection_permissions.

Removed AMO warning about mismatched minimum version.
