v1.1.0 — Bulk Operations, Cookie Diffing, and Improved Profiles

Cookie Manager v1.1.0

This feature release introduces bulk operations, cookie comparison between profiles, and several enhancements to the profile and export systems.

New Features

• Bulk cookie operations: Select multiple cookies using checkboxes and delete or export them in one action. Hold Shift to select a range. This is particularly useful on sites that set dozens of cookies.
• Cookie diff between profiles: Compare any two saved profiles side-by-side to see which cookies were added, removed, or changed. Accessible from the Profiles tab by selecting two profiles and clicking "Compare." Useful for debugging environment differences.
• Profile export and import: Save profiles to a JSON file and import them on another machine or browser. This makes it easier to share test environments with teammates or back up your profile collection.
• Duplicate cookie detection: The Cookies tab now flags duplicate cookies (same name, different domain or path) with a visual indicator. This helps catch configuration issues where multiple cookies compete for the same name.

Improvements

• Expanded health dashboard: The Health tab now includes a timeline view showing how the site's cookie security score has changed over your last 10 visits. This helps track whether a site is improving or degrading its cookie practices.
• Improved auto-delete rules: Rules now support wildcard patterns in cookie names (e.g., _ga* to match all Google Analytics cookies). Previously, rules could only match exact names or all cookies.
• Better dark mode contrast: Adjusted background and text colors in dark mode for improved readability, especially in the cookie detail view and health dashboard charts.
• Context menu improvements: The context menu now shows the number of cookies for the current site, so you can see the count without opening the popup.

Bug Fixes

• Fixed an issue where restoring a profile with expired cookies could silently fail on some cookies.
• Fixed keyboard navigation in the cookie list: arrow keys now move focus correctly when the list is filtered by search.
• Fixed a rare issue where the health score calculation could produce NaN on sites with zero cookies.

v1.0.1 — Bug Fixes and Polish

Cookie Manager v1.0.1

This patch release addresses several bugs reported since the initial launch and includes quality-of-life improvements across the extension.

Bug Fixes

• Fixed cookie editing on subdomains: Editing cookies scoped to subdomains (e.g., api.example.com) now correctly preserves the domain attribute instead of defaulting to the root domain.
• Fixed export on pages with special characters: Exporting cookies from URLs containing special characters (query strings, fragments) no longer produces malformed filenames.
• Fixed auto-delete rule timing: Rules set to "every 6 hours" now fire at the correct intervals. Previously, the alarm could drift when Chrome's service worker was suspended and restarted.
• Fixed profile restore on empty state: Restoring a profile when no cookies exist for the current domain no longer shows a brief error flash.

Improvements

• Faster popup load time: Reduced initial render time by deferring non-critical UI elements. The cookie list now appears approximately 40% faster on sites with large numbers of cookies.
• Better search highlighting: Search matches now highlight the matched portion of cookie names and values, making it easier to spot the relevant cookies.
• Improved Netscape export compatibility: The Netscape format output now includes the # Netscape HTTP Cookie File header line, improving compatibility with older versions of curl and wget.
• Updated translations: Corrected several translation strings in Spanish and Japanese.
