What's new in Waterfox 6.7.8
According to Waterfox's release notes, which are dated November 7, 2026, version 6.7.8 brings experimental iCloud Passwords support, a Feeds sidebar and fixes for feeds, external links and browser updates. The GitHub release tag from BrowserWorks shows that project founder MrAlex94 released this 07 Nov 13:03. Neowin listed it the next morning.
Here's the changelog, sorted by what matters most to Windows users:
- New: iCloud Passwords integration (experimental) on Windows and on macOS Sonoma 14 or later
- New: A Feeds sidebar with search and unread counts
- New: An "Update all feeds" button that refreshes every subscription
- Changed: Digital signature checks before browser updates are installed
- Changed: Updated Brazilian Portuguese and Simplified Chinese translations
- Fixed: Links opened from other apps sometimes failed to load when the content blocker was on
- Fixed: Damaged feed subscriptions now have backups and recovery
- Fixed: Better handling of disk errors during Windows updates
- Fixed: Feed handling for middle clicks, plus import and export error messages
- Fixed: Corner alignment in some curved tab styles
Section summary: This is a point release, but it's not just bug fixes. It adds a cross-platform password feature, finishes off the feed reader and tightens up the updater.
iCloud Passwords: Apple's password vault comes to Waterfox
The release notes say they added experimental iCloud Passwords support for macOS Sonoma 14 or later and Windows. To use it, you need Apple's password software installed. You then enable it under Settings > Passwords and autofill to fill passwords and verification codes.
The most important detail is easy to miss: Enabling it selects iCloud for new password saves. In other words, once the feature is on, new passwords go to iCloud, not Waterfox's own store. The notes don't say whether passwords you already saved in Waterfox are migrated. They also don't say what happens if Apple's software is missing or not running. Don't assume either behavior.
Waterfox credits community work for making this possible: Thanks to au2001's iCloud Passwords for Firefox project for figuring out to talk to Apple's password app.
How Waterfox got here
This feature has been building for a while. In version 6.6.8, Waterfox explained that users on macOS 14 → macOS 15.3 are already able to use the iCloud Passwords extension, but starting with macOS 15.4 Apple introduced a whitelist of supported browsers. The project said Waterfox was added to this list in December 2025 and will be available with the next macOS release. Waterfox later announced on Bluesky that macOS 26.3 just dropped and with it, Apple's iCloud Passwords extension now works with Waterfox!
Then, in the "what we are looking at next" section of the 6.7.0 notes, Waterfox listed native iCloud Keychain integration on macOS, meaning that passwords saved in Keychain will be available in Waterfox without the need for an extension. Version 6.7.8 puts the feature directly in Settings and adds Windows support, so it looks like that plan coming through. The 6.7.8 notes don't actually say how it works behind the scenes, though, so treat that link as our reading of the roadmap, not something Waterfox has confirmed.
What Windows users need first
Waterfox's notes say only "Apple's password software." Apple's own iCloud for Windows guide fills in the requirements:
- Two-factor authentication must be turned on for your Apple Account.
- The trusted device that receives the security code must run iOS 14, iPadOS 14, macOS 11 or later.
- Either Advanced Data Protection for iCloud must be on, or your Apple device must be within Bluetooth range of the PC.
- In iCloud for Windows, turn on Passwords & Keychain. You may need to click Approve and enter a code sent to a trusted device or phone number.
- Your passwords can then be managed in the iCloud Passwords app on Windows.
Apple's guide describes browser extensions for Chrome, Edge and Firefox. It does not mention Waterfox. Apple also says that turning on its extension disables the browser's built-in password saving. That fits with Waterfox's warning that new saves go to iCloud, but for Waterfox specifically, the only source we have is Waterfox's release note.
Success looks like this: Once Apple's prerequisites are in place and the option under Settings > Passwords and autofill is on, Waterfox can fill your saved passwords and verification codes. New passwords are saved to iCloud.
If it doesn't work: First check the basics in Apple's guide. Is two-factor authentication on? Is Passwords & Keychain enabled in iCloud for Windows? Is your Apple device within Bluetooth range, or is Advanced Data Protection on? Beyond that, remember this feature is labeled experimental. If you can't afford a lost login on a critical account, you might wait a release or two.
Section summary: If you use iCloud Passwords, this is a real convenience. But the setting changes where new passwords are saved, so decide where you want them to live before you flip it.
Feeds: the RSS reader keeps growing
Waterfox has been rebuilding its RSS support over several releases. Its changelog includes a 6.7.4 entry titled "6.7.4 - RSS returns and AI search controls" and a 6.7.6 entry called "More control over feeds and a multitude of fixes." Version 6.7.8 continues that work:
- A Feeds sidebar with search and unread counts, so you can check your feeds without leaving the page you're on
- An Update all feeds button that refreshes every subscription at once
- Backups and recovery for damaged subscriptions. Waterfox also says that feed settings now remain accessible if subscriptions cannot load.
- Opening a feed article with the middle mouse button now marks it as read. That fixes an annoyance for anyone who middle-clicks articles into new tabs.
- Improved feed import and export errors, canceling now leaves the previous result visible.
The notes don't say which feed formats or recovery methods are involved, so we won't guess.
Section summary: The feed reader now has a sidebar and some protection against corrupted subscriptions. If you missed the browser-based RSS readers of the 2000s, this is aimed at you.
Updates: signature checks and Windows disk-error handling
For security-minded readers, this one line may matter most: Waterfox now checks digital signatures before installing browser updates. Checking an update's signature before installing it is standard practice for software update systems. It helps make sure the installer came from the publisher and wasn't altered on the way. The notes don't say which signature format is used, how a failed check is handled or whether update delivery changes. It's a useful safeguard, not a promise that every update is safe.
On Windows, the release also notes improved handling of disk errors during Windows updates. It doesn't say which errors are covered or whether recovery happens automatically. It's welcome either way, coming right after 6.7.7, which the changelog titles "6.7.7 - JPEG XL improvements and update fixes". Updater reliability is clearly a priority right now.
Content blocker and external links
If you set Waterfox as your default browser and saw links from Outlook, Teams, Slack or other apps sometimes fail to open, this fix is for you. The release fixed links from other applications sometimes failing to load with the content blocker enabled. The notes don't name specific apps or offer a workaround for older builds. We use those apps only as examples of where external links come from, not as confirmed triggers.
The security advisory nobody can read yet
The 6.7.8 notes list MFSA 2026-126 and say that advisory details are not yet available from Mozilla. When the evidence for this article was gathered, Mozilla's advisory list ran only up to MFSA 2026-123, dated November 3, 2026. We can report the advisory number, but we can't confirm its severity, the affected components or what the vulnerability is. Still, a reference to a Mozilla advisory is a good reason to update promptly instead of waiting.
Context: what Waterfox is in 2026
Waterfox is a privacy-focused browser built on Firefox's Gecko engine. It removes telemetry and ships with ads, trackers and pop-ups blocked by default. According to its changelog, Waterfox 6.7 has moved to the ESR 153 platform and now features native tree tabs, the Nova style, and twelve colour palettes. Founder Alex Kontos started the project in 2011. Since returning to independent ownership in 2023, it has been run by BrowserWorks Ltd, which he owns, and it's funded through search partnerships, optional private-search subscriptions and donations.
The bottom line
Should you update? For most Waterfox users, yes. The signature checks, the fix for external links and the pending Mozilla advisory are reason enough. Treat the iCloud Passwords feature more cautiously. If you're already in Apple's ecosystem, bridging iCloud and a Gecko browser on a Windows PC could be very useful. Just remember that the feature is experimental and that new passwords will go to iCloud once it's on.
