v0.7.5

What's New

Session Tab Isolation

Each MCP session now automatically creates a dedicated browser tab on first tool call. Multiple sessions (e.g., two Claude Code windows) no longer stomp on each other's active tab.

Full E2E Tests in CI

All 21 e2e test files now run on every push to main (previously only 5 smoke tests). Fixed timeout issues and assertion mismatches from Phase 2 changes.

Bug Report Template

Added structured GitHub issue template for bug reports with required fields (extension version, MCP server version, MCP client).

Bug Fixes

• Fixed e2e test timeouts in CI (15s → 30s for tests with in-body page navigation)
• Fixed 3 e2e assertion failures from Phase 2 changes (table compaction, opacity:0 self-hidden, contenteditable whitespace)

v0.7.4: Phase 2 Snapshot Optimization

Phase 2 Snapshot Optimization

~31% additional token reduction on table-heavy pages through table row compaction and tree optimization.

New optimizations

• Table row compaction: Simple rows (≤1 leaf child per cell) rendered as single line with | separator
• Decorative image skip: [img] nodes without alt text are removed
• Empty cell skip: [cell] nodes with no children or name are removed

Bug fixes

• Fix span-wrapped cell text loss: Text inside <td><span>text</span></td> is now correctly captured via textContent fallback when all DOM children collapse
• Fix CSS selector injection: Escape special characters in label[for] selector to prevent crashes with unusual element IDs
• Fix opacity:0 visibility: Treat opacity:0 as self-hidden (like visibility:hidden) so children can still be visible — fixes hover/focus-revealed UI elements

Example output

Before (Phase 1):                    After (Phase 2):
[row]                                [row] Name | Value | Date
 [cell]
  [text "Name"]
 [cell]
  [text "Value"]
 [cell]
  [text "Date"]

v0.7.3: Reduce snapshot token waste (~29% reduction)

Snapshot Token Optimization (Phase 1)

Reduces token consumption of page_snapshot output by ~29% on typical pages through tree-level optimizations applied before text serialization.

Changes

• 1-space indentation (was 2-space) — biggest single saving (~22%)
• Skip [rowgroup] nodes — always structural (<thead>/<tbody>), zero information value; children promoted directly under [table]
• Skip single-child [listitem] — promotes the child to parent level, eliminating wrapper-only nodes

Impact

Site	Before	After	Reduction
GitHub repo	~2,816 tokens	~2,006 tokens	28.8%

Compatibility

• All 19 MCP tools verified on real sites (GitHub, Wikipedia, Hacker News, httpbin, etc.)
• @ref assignments unchanged — click, type, hover, drop_files all work correctly
• No changes to MCP server, schemas, or extension messaging

v0.7.2

What's New

focusRegion parameter for page_snapshot

Added a new optional focusRegion parameter to the page_snapshot tool that allows filtering snapshots to specific HTML5 landmark regions, reducing token usage.

Usage:

page_snapshot({ focusRegion: "main" })      // Main content only
page_snapshot({ focusRegion: "nav" })       // Navigation only
page_snapshot({ focusRegion: "footer" })    // Footer only (alias for contentinfo)
page_snapshot({ focusRegion: "sidebar" })   // Sidebar only (alias for complementary)
page_snapshot({ focusRegion: "banner" })    // Header/banner only

Token reduction (measured on real sites):

Site	focusRegion="main"	Best case
GitHub	~20% reduction	"nav": 86% reduction
Wikipedia	~4% reduction	"nav": 98% reduction
Hacker News	No effect (no landmarks)	Falls back to full tree

When the specified region is not found, the full tree is returned as a safe fallback.
