Status: Firefox upgraded from v135.0.1 to v147.0b3 (12 major versions) Date: 2025-12-19 Last Updated: 2025-12-19 (LibreWolf + Playwright patches synced with upstream) Total Patches: 45 (5 LibreWolf patches removed) Broken Patches: 25 (56%) Clean Patches: 20 (44%)

🔄 Upstream Patches Update (2025-12-19)

LibreWolf Patches Update

Action taken: Updated all LibreWolf patches from upstream repository Source: https://codeberg.org/librewolf/source (Firefox 146.0.1)

Playwright Patch Update

Action taken: Updated 0-playwright.patch from upstream Playwright repository Source: https://github.com/microsoft/playwright/blob/main/browser_patches/firefox/patches/bootstrap.diff

✅ Updated Patches (17 patches)

All LibreWolf patches have been updated to match Firefox 146 upstream versions:

bootstrap.patch
bootstrap-without-vcs.patch.opt
arm.patch.opt
rust-gentoo-musl.patch
mozilla_dirs.patch
dbus_name.patch
devtools-bypass.patch
urlbarprovider-interventions.patch

ui-patches/firefox-view.patch
ui-patches/handlers.patch
ui-patches/hide-default-browser.patch
ui-patches/remove-cfrprefs.patch
ui-patches/remove-organization-policy-banner.patch

❌ Deleted Patches (5 patches - no longer in LibreWolf upstream)

These patches have been removed as they no longer exist in LibreWolf's repository:

context-menu.patch - Was broken (1 failed hunk) ✅ Removed .rej file
remove_addons.patch - Was broken (4 failed hunks) - ⚠️ .rej files still exist (orphaned)
sed-patches/allow-searchengines-non-esr.patch - Was broken (1 failed hunk) ✅ Removed .rej file
sed-patches/disable-pocket.patch - Was broken (2 failed hunks) - ⚠️ .rej files still exist (orphaned)
ui-patches/remove-branding-urlbar.patch - Was working ✅

⚠️ New Issues from Updates

mozilla_dirs.patch (updated from LibreWolf) now has 1 NEW failed hunk:
- toolkit/xre/nsXREDirProvider.cpp.rej
0-playwright.patch (updated from Playwright upstream):
- MAJOR IMPROVEMENT: Reduced from 34 → 23 failed hunks (33% improvement!)
- Fixed 11 files that now apply cleanly
- Still broken: 17 files need manual adaptation to Firefox 147
1-leak-fixes.patch now has 1 NEW failed hunk:
- toolkit/components/enterprisepolicies/EnterprisePoliciesParent.sys.mjs.rej
- This broke because upstream Playwright changed how it patches this file

Net Impact:

LibreWolf: Deleted 4 broken patches, added 1 new broken patch (mozilla_dirs)
Playwright: Improved significantly (11 files fixed), but added 1 broken patch (1-leak-fixes)
Still have orphaned .rej files from deleted patches (need manual cleanup)
Actual broken patches: 25 (was 27, then 24, now 25 after Playwright update)

Summary Statistics

Total .rej files: 58 rejection files across the codebase (after all updates)
- 6 orphaned .rej files from deleted patches (need manual cleanup)
- 52 active .rej files from broken patches
Total failed hunks: ~73 individual hunks that need manual resolution (reduced from ~82!)
Patches needing updates: 25 patches
- 22 patches that were already broken
- 1 NEW broken patch from LibreWolf update (mozilla_dirs.patch)
- 1 NEW broken patch from Playwright update (1-leak-fixes.patch)
- 1 IMPROVED patch (0-playwright.patch: 34 → 23 hunks)
Patches working perfectly: 20 patches

Execution Plan

Phase 1: Preparation (10 min)

✅ DONE: Identified all broken patches (27 patches)
✅ DONE: Categorized by priority
TODO: Clean workspace: make revert
TODO: Create backup of current patches directory

Phase 2: Critical Patches (4-8 hours)

Step 1: Update Playwright Patch (2-4 hours)

Download Playwright's latest bootstrap.diff
Compare with current 0-playwright.patch
Strategy decision:
- If Playwright has v147: Replace entire patch
- If not: Manual update of all 34 failed hunks
Test standalone: Apply only Playwright patches, verify build
Success criteria: Zero .rej files for Playwright

Step 2: Fix fingerprint-injection.patch (1-2 hours)

Use make workspace ./patches/fingerprint-injection.patch
Resolve 9 failed hunks across 5 files
Pay special attention to Navigator.cpp (overlaps with Playwright)
Test: Basic build + browser launch
Success criteria: Core fingerprinting loads without errors

Step 3: Fix Roverfox Context Patches (2-3 hours)

Fix font-fingerprinting.context.patch (8 hunks)
Fix webrtc-ip.context.patch (2 hunks)
Note: Both patches touch nsGlobalWindowInner.cpp
Test: Verify RoverfoxStorageManager integration
Success criteria: Per-context isolation works

Phase 3: Stealth Patches (2-3 hours)

Fix in order:

webgl-spoofing.patch (3 hunks, 30-45 min)
font-hijacker.patch (2 hunks, 20-30 min)
audio-context-spoofing.patch (1 hunk, 10-15 min)
geolocation-spoofing.patch (1 hunk, 10-15 min)
voice-spoofing.patch (1 hunk, 10-15 min)
webrtc-ip-spoofing.patch (1 hunk, 10-15 min)

Success criteria: All spoofing features functional

Phase 4: LibreWolf Patches (30-45 minutes)

✅ MOSTLY COMPLETE: LibreWolf patches updated from upstream (Firefox 146)

17 patches updated to latest versions
4 broken patches deleted (no longer needed)
2 patches auto-fixed by update (hide-default-browser, remove-cfrprefs)
Only 4 LibreWolf patches remaining to fix:
- custom-ubo-assets-bootstrap-location.patch (1 hunk) - 10 min
- mozilla_dirs.patch (1 hunk) ⚠️ NEW - 10-15 min
- network-patches.patch (1 hunk) - 15 min
- no-search-engines.patch (2 hunks) - 15-20 min
- windows-theming-bug-modified.patch (1 hunk) - 10 min

Total estimated time: 60-70 minutes for 5 patches

Success criteria: Browser builds with all UI customizations

Phase 5: Integration Testing (2-3 hours)

Clean apply all patches: make revert && make dir
Verify zero .rej files: find . -name "*.rej"
Full build: make build (30-60 min build time)
Smoke tests:
- Browser launches
- Navigation works
- Console has no errors
Automated tests: make tests (run all 51 test files)
Manual fingerprinting tests:
- WebGL spoofing
- Canvas fingerprinting
- Font fingerprinting
- Audio context
- Screen dimensions
- Geolocation
- WebRTC IP handling

Success criteria: All tests pass, all features work

Phase 6: Cleanup & Documentation (30 min)

Remove all .rej, .orig, .bak files
Document changes made to each patch
Update changelog/release notes
Git commit updated patches
Tag release (if applicable)

Time Estimates

Phase	Optimistic	Realistic	Pessimistic
Phase 1: Prep	~~10 min~~ ✅ DONE	~~15 min~~ ✅ DONE	~~30 min~~ ✅ DONE
Phase 2: Critical	4 hours	6 hours	8 hours
Phase 3: Stealth	1.5 hours	2.5 hours	3.5 hours
Phase 4: LibreWolf	~~1.5 hours~~ 30 min	~~2.5 hours~~ 45 min	~~3.5 hours~~ 70 min
Phase 5: Testing	2 hours	3 hours	4 hours
Phase 6: Cleanup	20 min	30 min	45 min
TOTAL	8 hours	12.5 hours	17.75 hours

Realistic estimate: 1.5 work days (12-13 hours) - saved ~1.5 hours by updating LibreWolf patches

Update: LibreWolf update had mixed results:

✅ Fixed 2 patches automatically
❌ Introduced 1 new broken patch (mozilla_dirs)
❌ Net benefit: ~1.5 hours saved (not 2 hours as initially hoped)

Documentation updated

Notes & Warnings

⚠️ File Overlap Conflicts:

dom/base/Navigator.cpp - Modified by both Playwright AND fingerprint-injection
dom/base/nsGlobalWindowInner.cpp - Modified by BOTH roverfox patches
dom/media/webrtc/jsapi/PeerConnectionImpl.cpp - Modified by both WebRTC patches

These files need careful attention to ensure all patch intents are preserved.

⚠️ Playwright Upstream Sync: The 0-playwright.patch is critical infrastructure. Check if Playwright has already updated for Firefox 147:

https://github.com/microsoft/playwright/blob/main/browser_patches/firefox/patches/bootstrap.diff
Check their supported Firefox versions

⚠️ Build Time: Full Firefox builds can take 30-90 minutes depending on hardware. Plan accordingly.

⚠️ Backup: Before starting, backup the current patches directory:

cp -r patches patches.backup.v135

Document created: 2025-12-19 Firefox version: v147.0b3-beta.25 Previous version: v135.0.1-beta.24 Status: Planning complete, ready for execution
