In addition to the previous updates, Version 1.2 now includes
Query-Based Smart Grouping. Here is the breakdown of what's new
after our latest fix:

1. Support for "Watch IDs"
2. The Problem: Many streaming sites use a single page (like /watch)
   and change the video via a ID in the link (e.g., ?id=62560). My
   previous logic ignored these, causing duplicates.
3. The Solution: The extension now recognizes "Stable IDs" in the
   URL. It identifies that id=62560 is the "Show" and episode=2 is
   just a temporary state.
4. Result: Even if the URL looks almost the same, Conwatch correctly
   identifies the series and replaces the old episode.
5. Expanded Site Compatibility
   I added a list of common "ID Keys" used by various streaming
   platforms:
6. id
7. show_id / series_id
8. bangumi_id (Common for anime sites)
9. playlist_list (Common for video collections)
10. More Reliable "Series Fingerprinting"
11. By combining the Hostname + Path + ID Parameter, we've created a
    very specific "fingerprint" for every show you watch.
12. This makes the extension much more accurate at grouping episodes
    on sites that don't follow standard URL structures or don't put
    the show name in the page title.
13. Lowercase Normalization
14. Series IDs are now converted to lowercase. This prevents the
    extension from thinking "My Show" and "my show" are different
    entries if a website is inconsistent with its naming.

In version 1.2, the headline feature is Smart Series Grouping. Here
is exactly what is new:

1. Automatic Episode Replacement
2. The Change: Previously, watching Episode 1 and then Episode 2
   would create two separate entries in your watchlist.
3. The New Behavior: Conwatch now recognizes when a video belongs to
   the same series. When you start a new episode, it automatically
   replaces the old one. Your watchlist stays clean, showing only
   your most recent progress for that specific show.
4. Multi-Layer Series Detection
   To make the grouping accurate without breaking for movies or
   different websites, we added three layers of "intelligence":
5. Metadata Scraper: It looks for hidden SEO tags (og:video:series)
   that streaming sites use to identify shows.
6. URL Path Analysis: It analyzes the folder structure of the link
   (e.g., /show/naruto/ep1 and /show/naruto/ep2 are grouped because
   they share the /show/naruto/ path).
7. Strict Title Parsing: It uses a refined regex to find episode
   numbers (S01E01, Ep. 5) while ignoring non-series numbers (like
   years or movie parts).
8. Website-Locked Sync
9. The Change: Replacement is strictly locked to the same domain.
10. The Result: If you watch Naruto on Netflix and then watch Naruto
    on YouTube, the extension treats them as separate entries. This
    ensures your progress and links remain valid for the specific
    site you were using.
11. Pin State Preservation
12. If you "Pin" a series to the top of your side panel, it stays
    pinned even when it gets updated with a new episode. You won't
    have to re-pin it every time you move to the next episode.
13. Lowercase Normalization
14. Series matching is now case-insensitive, preventing duplicates if
    a website inconsistently names a show as "Breaking Bad" on one
    page and "BREAKING BAD" on another.

Notes to Reviewer:

• Security Fixes: We've addressed "unsafe innerHTML" warnings by refactoring the DOM creation in sidepanel.js to use
  document.createElement and textContent, enhancing security and preventing potential XSS vulnerabilities.
• Version Update: The extension version has been incremented to 1.1.
• Manifest Configuration (manifest-firefox.json):
  • The browser_specific_settings.gecko.data_collection_permissions key has been explicitly included to comply with
    Firefox Add-on Store publishing requirements, despite potentially triggering a strict_min_version warning. This
    is intentional for submission compliance.
  • The sidePanel.setPanelBehavior call in background.js is conditional (if (chrome.sidePanel)), ensuring it only
    executes in compatible Chromium browsers and can be safely ignored for Firefox review.
