Firefox changelog

0.1.9

Clearer empty JSON-LD diagnostics and reliability improvements - 2026-07-17

Schema diagnostics

• Empty JSON-LD script blocks now explain that the block has no content and should contain valid JSON-LD or be removed, instead of showing Unexpected EOF alone.

Reliability and performance

• Improved reliability across the workspace while preserving current navigation, filtering, sorting, settings, downloads, and export formats.
• Reduced the content-layer payload while keeping the existing browser support and feature set.

Firefox note

• Includes the clearer empty JSON-LD diagnostic while continuing to omit the Chromium-only JavaScript toggle.

0.1.8

On-demand link checking and richer technical diagnostics - 2026-07-16

Link checking

• Added on-demand link checking for batches of up to 250 URLs with retry controls, rate-limit feedback, exact HTTP status codes, redirect results, and observed final destinations.
• Added inline on-page link-status badges, status filters, clearer no-response and 4xx handling, persistent link sessions, incremental rendering, and link-status exports.

Diagnostics and settings

• Added source-linked schema diagnostics and improved robots crawler filtering and breadcrumb validation.
• Clarified accessibility-tree locations and improved issue locators with the best available page or source URL.
• Added branded settings controls for HTTP status capture, PageSpeed auto-run, and Web Vitals cache management.

Firefox note

• Link checks support up to 250 URLs per batch, inline status badges, status filters, retries, and exports; the Chromium-only JavaScript toggle remains hidden.

0.1.7

Web Vitals workspace with field, lab, and local performance data - 2026-07-10

Web Vitals

• Added a Web Vitals workspace with local Core Web Vitals, CrUX current field data, CrUX history charts, PageSpeed Insights lab diagnostics, exports, and refresh controls.
• Shows mobile and desktop CrUX history charts side by side by metric, so Mobile LCP pairs with Desktop LCP, Mobile FCP pairs with Desktop FCP, and so on.
• Labels CrUX data as URL-level when Google has exact page data and sitewide when origin-level fallback is used.
• Adds Web Vitals exports in copy, TSV, CSV, JSON, Markdown, and TXT formats.

Performance data handling

• CrUX and CrUX History use Google's Chrome UX Report APIs for real-user field data where available.
• PageSpeed Insights uses Google's PageSpeed API for synthetic Lighthouse lab diagnostics when users run it or enable auto-run.
• Remote Web Vitals responses are cached locally so repeat views avoid unnecessary API calls, with a Refresh action when users want fresh data.
• About, privacy, docs, and store copy now distinguish local page audits from optional Google performance API requests.

0.1.6

Deeper exports, robots groups, and accessibility tree controls - 2026-06-30

Export quality

• Improved export coverage across Overview, HTTP Trace, Headings, Links, Images, Schema, Robots, Social, Style, page copy, raw audit output, rendered accessibility data, SERP previews, and image ZIP manifests.
• Improved readable Markdown and text exports so reports scan cleanly while CSV, TSV, and JSON preserve full source values for analysis.
• Added clearer selected-report download controls, left-aligned export actions, and tooltips that explain each export format and action.
• Improved HTTP redirect and final-response exports with per-hop downloads plus combined all-entry downloads when multiple HTTP entries are available.

Robots and crawler review

• Expanded Robots review with Core, Detected, AI Search, AI Training, AI User Retrieval, and Other crawler groups.
• Added selected crawler-group exports with Core and Detected selected by default, stable group counts, de-duplicated output rows, Select All, Clear, and Download Selected.
• Added richer robots export output for crawler access status, matched rules, allowed/blocked results, and tester results.
• Changed the Robots navigation count to reflect detected robots.txt crawlers instead of the full known-crawler catalog.

Accessibility and schema review

• Improved the rendered accessibility tree with schema-style multi-select filters, sorting, expand/collapse-all controls, clearer expanded details, and stable expanded state while sorting.
• Improved accessibility issue locators so Copy Path and details include the best available URL or page URL plus DOM path, making issues easier to find and fix.
• Expanded accessibility JSON output so available node metadata is included for deeper inspection.
• Improved schema sorting and filter controls so expanded blocks stay open and filter labels scan cleanly.

0.1.5

HTTP tracing and cleaner page exports - 2026-06-25

HTTP and redirects

• Added an HTTP Trace workspace section for status codes, response headers, server redirects, final response details, and copy/download actions.
• Added local redirect labeling for HTTP redirects, JavaScript redirects, and meta-refresh redirects.

Page copy and exports

• Added page-copy exports for readable rendered content in TXT, Markdown, HTML, DOCX, and ODT formats.
• Added Page Copy download actions to the Exports screen and context menu.
• Added clearer download actions for page images, live robots.txt files, sitemap URLs, robots test results, and inspected CSS.
• Improved robots test-result exports so matched and ignored rules export into separate columns instead of spilling into extra cells.

Workspace behavior

• Simplified the product around the in-page overlay workspace and removed stale popup and side-panel workflow references.
• Improved the rendered accessibility tree so the preview starts with the first 100 semantic nodes and can expand on demand.
• Added accessibility issue details with locator paths, fix guidance, and Copy Path actions.
• Cleaned duplicated rendered link text from nested navigation links and improved link sorting stability.
• Moved the webmaster-tools compare action to the main right-click menu and shortened the SEO Tools and Webmaster Tools menu labels.
• Improved Google Search Console and Bing Webmaster Tools shortcuts for compare and URL-prefix workflows.
• Improved overlay open/close reliability, active-tab reload handling, and status-badge refresh behavior.
• Improved Safari status badges so HTTP status codes show more reliably after page loads, including search result pages.
• Polished filtered schema downloads, robots crawler testing, and custom user-agent handling.

Firefox note

• HTTP trace capture is available; the JavaScript toggle stays hidden because Firefox does not expose the same content settings API.

0.1.4

Workspace polish and deeper exports - 2026-06-20

Interface polish

• Polished the full in-page workspace with cleaner spacing, clearer section headers, compact controls, and less wasted space.
• Polished Social, Style, Webmaster Tools, Tools, Exports, About, and Support screens for cleaner scanning and less vertical space.

Overview and exports

• Expanded Overview with richer technical SEO visibility, including response headers, technical signals, discovery signals, source-vs-rendered checks, and review items.
• Improved Quick Exports and the Exports page so users can export more focused datasets: issues, metadata, technical, discovery, headings, links, images, schema, robots, social, style, SERP, tools, accessibility, and support data where available.

Review workflows

• Improved Robots testing with grouped crawler presets, custom user-agent testing, editable robots.txt draft testing, matched-rule context, clearer line highlighting, and downloadable test results.
• Improved Schema review with cleaner cards, filters, sorting, Google warning/error chips, highlighted issue lines, and pretty JSON output.
• Improved Links and Images with multi-select filters, sorting, and downloads for filtered or selected results.
• Improved SERP previews with cleaner desktop and mobile layouts, compact enhancement controls, clearer preview exports, and PNG/WebP download options.

Firefox note

• The JavaScript toggle stays hidden because Firefox does not expose the same content settings API.

0.1.3

Cross-browser reach and clearer guidance - 2026-06-16

Browser support

• Added browser-specific support for Chrome, Edge, Firefox, and Safari so users could use the toolkit across more browsers.
• Added visible version information and clearer About and support paths.

SEO workflows

• Added Google Search Console and Bing Webmaster Tools shortcuts for opening property, indexing, inspection, and performance views.
• Added schema status tooltips explaining local parse status and local rich-result guidance.
• Improved Robots Compare Crawlers so it starts with Googlebot selected and clears compare selections when closed.
• Added or expanded the accessible color palette and rendered accessibility tree experience where supported.

Firefox note

• Firefox kept page analysis, exports, schema review, robots tools, accessibility tools, and webmaster shortcuts without the Chromium-only JavaScript toggle.

0.1.2

Broader browser workflow - June 2026

Expanded access

• Expanded beyond the initial Chrome workflow toward cross-browser support.
• Added more complete workspace coverage for robots, social, style, SERP, webmaster shortcuts, and tools.

Exports and comparison

• Improved local export behavior for CSV, TSV, JSON, Markdown, image ZIP, SERP images, and accessibility JSON where supported.
• Improved source-vs-rendered comparison so users could better spot JavaScript-rendered SEO differences.

Firefox note

• Firefox used browser-compatible local download behavior and hid the Chromium-only JavaScript toggle.
