Chromium and Firefox: Bugs, Manifest, and Translations

Filed under

  • Bounty or paid work offered to fix subtle Chromium bug • The Register

    For the past three months, an elusive bug in Google's open-source Chromium project has been causing a small percentage of Chrome extensions to silently fail.

    The bug affects about three to five percent of users of several popular Chrome browser extensions, according to Jói Sigurdsson, founder and CEO of CrankWheel, maker of a screen-sharing extension for sales teams.

    As described in the Chromium bug report, event handlers registered via chrome.browserAction.onClicked.addListener sometimes will fail to get dispatched when the associated button or icon is clicked by the user. For an individual using an affected extension, the result would be that the extension's button just stops responding to click events.

  • Short Topix: GMail Trick Reveals Who Is Selling Your Data

    Anyone who follows web browser development even a little has heard of Google's push for the adoption of Manifest V3 and the havoc it is anticipated to bring to many web browser extensions. Most significantly, Manifest V3 eliminates Web Request API, and replaces it with Declarative Net Request API. This change will seriously cripple many ad blocker extensions, which rely on the Web Request API to effectively block unwanted ads on websites visited by the end user. Currently, no new Chrome extensions are being accepted that are based on Manifest V2, which features the Web Request API.

    Starting in June 2023, Google will no longer allow extensions based on Manifest V2 to continue to run, replacing Manifest V2 with Manifest V3. Mozilla, on the other hand, plans to start implementing Manifest V3 in late 2022. But, Mozilla also plans to maintain support for the Web Request API from Manifest V2, allowing ad blocking browser extensions to continue to work.

    If you are a Chromium user (or the user of any browser based on it, such as Google Chrome, Opera, Brave, etc.), the implementation of Manifest V3 has already begun. When fully implemented, expect your ad blockers to either cease functioning or to be severely crippled under Chromium-based browsers.

    It makes sense that Google would want to cripple ad blockers. Consider that the vast majority of Google's fortunes are made from selling advertising, especially advertising that is targeted at individual users. If an ad is blocked, it's not viewed by the end user, and Google gets no money when you cannot view it. Also, when you can't view it, you can't click through the ad to visit the advertiser's website. Those "click counts" are important, especially if you own the website on the other end, or if you sell advertising based on click counts.

    Developers of web browser extensions – especially ad blocker extensions – have been very vocal about the implementation of Manifest V3. None have been more vocal than Raymond Hill, the creator of the uBlock Origin ad and content blocker.

    Hang on to your seats, gang. This is going to be one rocky, bumpy, crater-filled ride for the next year or so. If you abhor ads on your web pages (like most people do), prepare for the terrifying reality that you can no longer hide them or prevent them from appearing. But then again, there's always Firefox. It makes me glad to be a Firefox user.

  • Firefox Translations: Client Side On-Demand Translations

    Move on over, Google Translate. Step aside, DeepL. There's a new kid in the translation neighborhood.

    Meet Firefox Translations. Unlike the other online translators out there (including the two already mentioned), Firefox Translations is a client-side translator. While the others are cloud-based, Firefox Translations translates the data in your browser on your local computer, so no information is ever transmitted to or from your computer during the translation.


    Once a page is loaded in one of the supported languages (different from the language used on your computer), you should see the above toolbar in Firefox. Just click on the "Translate" button. If this is the first time you're using the tool for a particular language, it may take a few seconds to download the translation "dictionary" to your computer. It will then work to translate the page into your native language.

  • How to Add Repository to Debian

    APT checks the health of all the packages, and dependencies of the package before installing it. APT fetches packages from one or more repositories. A repository (package source) is basically a network server. The term "package" refers to an individual file with a .deb extension that contains either all or part of an application. The normal installation comes with default repositories configured, but these contain only a few packages out of an ocean of free software available. In this tutorial, we learn how to add the package repository to Debian.

  • Making a Video of a Single Window

    I recently wanted to send someone a video of a program doing some interesting things in a single X11 window. Recording the whole desktop is easy (some readers may remember my post on Aeschylus which does just that) but it will include irrelevant (and possibly unwanted) parts of the screen, leading to unnecessarily large files. I couldn't immediately find a tool which did what I wanted on OpenBSD [1] but through a combination of xwininfo, FFmpeg, and hk I was able to put together exactly what I needed in short order. Even better, I was able to easily post-process the video to shrink its file size, speed it up, and contort it to the dimension requirements of various platforms. Here's a video straight out of the little script I put together: [...]

    And it got me thinking about what you can and can’t do — what you do and don’t have control over.

  • allow-new-zones in BIND 9.16 on CentOS 8 Stream under SELinux

    We run these training systems with SELinux enabled (I wouldn’t, but my colleague likes it :-), and that’s the reason I aborted the lab: I couldn’t tell students how to solve the cause other than by disabling SELinux entirely, but there wasn’t enough time for that.

  • Will the IndieWeb Ever Become Mainstream?

    This is an interesting question, thanks for asking it, Jeremy. I do have some history with the IndieWeb, and some opinions, so let’s dive in.

    The short answer to the question is a resounding no, and it all boils down to the fact that the IndieWeb is really complicated to implement, so it will only ever appeal to developers.

  • How to Install CUPS Print Server on Ubuntu 22.04

    If your business has multiple personal computers in the network which need to print, then we need a device called a print server. Print server act intermediate between PC and printers which accept print jobs from PC and send them to respective printers. CUPS is the primary mechanism in the Unix-like operating system for printing and print services. It can allow a computer to act as a Print server. In this tutorial, we learn how to set up CUPS print server on Ubuntu 22.04.

Open Hardware: XON/XOFF and Raspberry Pi Pico

  • From XON/XOFF to Forward Incremental Search

    In the olden days of computing, software flow control with control codes XON and XOFF was a necessary feature that dumb terminals needed to support. When a terminal received more data than it could display, there needed to be a way for the terminal to tell the remote host to pause sending more data. The control code 19 was chosen for this. The control code 17 was chosen to tell the remote host to resume transmission of data.

  • Raspberry Pi Pico Used in Plug and Play System Monitor | Tom's Hardware

    Dmytro Panin is at it again, creating a teeny system monitor for his MacBook from scratch with help from our favorite microcontroller, the Raspberry Pi Pico. This plug-and-play system monitor (opens in new tab) lets him keep a close eye on resource usage without having to close any windows or launch any third-party programs. The device is Pico-powered and plugs right into the MacBook to function. It has a display screen that showcases a custom GUI featuring four bar graphs that update in real-time to show the performance of different components, including the CPU, GPU, memory, and SSD usage. It makes it possible to see how hard your PC is running at a glance.
