Botnet Part 2: The Web is Broken by Jan Wildeboer. So there is a (IMHO) shady market out there that gives app developers on iOS, Android, MacOS and Windows money for including a library into their apps that sells users network bandwidth.

The Guardian's new whistleblower tool buries leaks to journalists within its own readers' everyday traffic by Joshua Benton. (previously: AdLeaks)

Attorney General Bonta Urges Immediate Action by Meta to Prevent Investment Scam Advertisements on its Platforms | State of California - Department of Justice - Office of the Attorney General (Don't tell me California has a strong privacy law. If we had a strong privacy law there would be a bunch of people in CPPA raid jackets carrying servers and boxes of records out of the Meta offices right now. More: some ways that Facebook ads are optimized for deceptive advertising)

Why Denmark Is Dumping Microsoft Office and Windows for LibreOffice and Linux by Steven Vaughan-Nichols. (why, yes, the future of human civilization does depend on European bureaucrats finally pulling off the Year of the Linux Desktop…so we should have nothing to worry about)

WPP attacks Publicis-owned Epsilon SSP in rare public spat - Ad Age by Jack Neff, Ewan Larkin, and Brian Bonilla. (I'm Team WPP on this one. The test did involve an an unusual buying pattern, but saying that most brands don't buy that way is like saying most restaurant diners don't check the back of the fridge like a health inspector, or most word processor users don't make a document title with 1025 emoji in it like a software tester.)

Taylor Swift now owns all the music she has ever made: a copyright expert breaks it down by Wellett Potter. Swift has repeatedly emphasised the need for artists to retain control over their work and to receive fair compensation. In a 2020 interview she said she believes artists should always own their master records and licence them back to the label for a limited period.

Crate of the Week

This week's crate is optics, a typesafe, fully featured lens library.

Thanks to Akos Vandra for the self-suggestion!

Please submit your suggestions and votes for next week!

Calls for Testing

An important step for RFC implementation is for people to experiment with the implementation and give feedback, especially before stabilization.

If you are a feature implementer and would like your RFC to appear in this list, add a call-for-testing label to your RFC along with a comment providing testing instructions and/or guidance on which aspect(s) of the feature need testing.

Let us know if you would like your feature to be tracked as a part of this list.

The Mozilla Blog: Firefox features that help you plan a trip (and take it)

Browser window and smartphone with a sync icon, representing syncing data between devices.<figcaption class="wp-element-caption">Start planning on your laptop, pick it back up on your phone with Firefox sync. </figcaption>

Most travel plans start with a handful of tabs. A map here, a few guides there. Then a flurry of bookings, logins and maybe a PDF form you're supposed to sign with your finger. Next thing you know, you're in line at the car rental counter with 3% battery, no confirmation number, and no address for where you're staying.

Firefox can't hand you a charger. But it can keep up before your trip and while you're on it. Haven't downloaded Firefox mobile yet? Now's a good time. Once you enable sync on Firefox mobile, all your travel bookmarks and tabs will come with you - ready to access quickly when you need them. Strong privacy protections are built in by default.

Here are a few features that help you plan, book and get where you're going:

Sync

Start planning on your laptop, pick it back up on your phone. Tabs like your hotel reservation page, bookmarks, passwords and more come with you, so you're not stuck emailing yourself links or searching "best vegan pizza rome" for the third time. Sign in to your Mozilla account to enable sync and access your data across your devices. It stays private and encrypted - even from us. (Firefox sync works in most places, but it's not available in every region.)

AI chatbot in your sidebar

Firefox lets you keep an AI chatbot in the sidebar while you browse. Useful when you're planning an itinerary, overthinking a layover, or asking it to generate a packing list based on the weather, your mood, and your inability to travel light.

Right-click the sidebar > customize sidebar > check "AI chatbot." Pick from tools like Claude, ChatGPT, Gemini and others (availability may vary by region).

Firefox browser window showing the “Customize sidebar” panel, with options to enable vertical tabs and move the sidebar to the right. Under “Firefox tools,” the “AI chatbot” is checked, while “Tabs from other devices,” “History,” and “Bookmarks” are unchecked. A link to “Manage Firefox settings” is at the bottom.

Password manager and generator

Firefox can save your passwords, fill them in when you need them and generate more secure ones than "plzletmein!"

PDF editor

Sometimes the thing that holds up your travel plans is a PDF: tour sign-up sheets, car rental instructions, a transit map. Firefox's built-in PDF editor lets you fill out, sign and annotate PDFs directly in the browser - no downloads, no printing required. Works on desktop and mobile.

Using the text tool in a PDF editor to add and edit text with options for color and size.

Tab groups

Tab groups let you organize your tabs by topic - flights, food, logistics, backup food - so you're not digging through a sea of identical tab titles wondering where the train schedule went.

Vertical tabs

Once the tab count crosses into the regrettable zone, vertical tabs help you see what you're working with. Everything's listed neatly on the side, so you can find the one tab with actual answers and stop clicking through five versions of "best day trips near Milan."

Firefox browser window open to a TripAdvisor page about Milan, Italy, with a large image of Piazza del Duomo featuring the cathedral, nearby buildings, and people walking. The sidebar on the left shows open tabs related to Milan travel, including Google Flights, YouTube, Reddit, Google Docs, and Maps.

Right-click the toolbar > turn on vertical tabs.

Built-in translation

Firefox can translate full pages instantly for supported languages. Useful when you're trying to fill out a form, make a reservation, or read a menu where the only word you recognize is cornetto.

VPN extension for Windows

Sometimes travel means needing to book something as if you're already there, or reading the news like you're still at home. With Mozilla VPN, you can locate yourself wherever in the world you want - even back home. And with the VPN extension for Windows, you can do this on a per site basis, so you can check what you need without changing your whole device's location. (Available as part of a paid subscription.)

Firefox keeps up with your tabs, logins, pages, even the one in another language. Just remember to pack your charger.
