This is cross-posted from a Medium article by Akshitha Shetty, a Summer of Code student I have been mentoring. It’s been a pleasure and I wish her luck in her next endeavor!
For me, getting all set to read a book would mean spending hours hopping between stores to find the right lighting and mood to get started. But with Firefox’s Reader Mode it’s now much more convenient to get reading on the go. And this summer, I have been fortunate to shift roles from a user to a developer for the Reader Mode . As I write this blog, I have completed two months as a Google Summer of Code student developer with Mozilla. It has been a really enriching experience and thus I would like to share some glimpses of the project and my journey so far.
Motivation behind choosing this organization and project
I began as an open-source contributor to Mozilla early this year. What really impressed me was how open and welcoming Mozillians were. Open-source contribution can be really intimidating at first. But in my case, the kind of documentation and direction that Mozilla provided helped me steer in the right direction really swiftly. Above all, it’s the underlying principle of the organization — “people first” that truly resonated with me. On going through the project idea list, the “Firefox Reader Mode Revamp” was of great interest to me. It was one of the projects where I would be directly enhancing the user-experience for Firefox users and also learning a lot more about user-experience and accessibility in the process.
Redesign of the Reader mode in making
The new design of the reader mode has the following features -
- A vertical toolbar is to replaced by a horizontal toolbar so that it is the sync with the other toolbars present in Firefox.
- The toolbar is now being designed so that it complies with the Photon Design System (the latest design guidelines proposed by the organization).
- The accessibility of the Reader Mode is being improved by making it keyboard friendly.
Thanks to Abraham Wallin for designing the new UI for the Reader mode.
Get Set Code
Once the design was ready, I began with the coding of the UI. I thoroughly enjoyed the process and learnt a lot from the challenges I faced during this process. One of the challenges I faced during this phase was to make the toolbar adjust it’s width as per the content width of the main page. This required me to refactor certain portions of the existing code base as well make sure the newly coded toolbar follows the same.
To Sum it all up
All in all, it has been a really exciting process. I would like to thank my mentor — Eitan Isaacson for putting in the time and effort to mentor this project. Also I would like to thank — Gijs Kruitbosch and Yura Zenevich for reviewing my code at various points of time.
I hope this gets you excited to see the Reader Mode in its all new look ! Stay tuned for my next blog where I will be revealing the Revamped Reader Mode into action.
I often need to quickly test a snippet of HTML, mostly to see how it interacts with our accessibility APIs.
Instead of creating some throwaway HTML file each time, I find it easier to paste in the HTML in devtools, or even make a data URI.
Last week I spent an hour creating an extension that allows you to just paste some HTML into the address bar and have it rendered immediately.
You just need to prefix it with the
html keyword, and you’re good to go. Like this
html <h1>Hello, World!</h1>.
You can download it from github.
There might be other extensions or ways of doing this, but it was a quick little project.
userChrome.css is not guaranteed to work between versions of Firefox and may lead to hard-to-diagnose bugs. Use at your own risk!)
Firefox Quantum has made a clean break from Firefox’s legacy addons. Hooray!
A casualty of this change is the ability to have addons that fundamentally alter Firefox’s user interface. This can be a problem if you depended on this for accessibility needs. Say, you had an addon that enlarged the fonts in Firefox’s chrome.
Luckily, not all is lost. With some CSS knowledge, you can customize the Firefox user interface as much as you need. Simply drop some CSS rules into $PROFILE/chrome/userChrome.css.
Here is an example rule that employs large yellow on black text:
font-size-adjust: 0.75 !important;
background-color: #000 !important;
color: yellow !important;
The effect on Firefox will be dramatic:
Note, this will break things, and it will not be perfect. Before using this kind of solution check what accessibility features your platform provides.
After porting Aaron’s NoCoffee extension to Firefox, I thought it would be neat to make a camera version of that. Something you can carry around with you, and take snapshots of websites, signs, or print material. You can then easily share the issues you see around you.
I’m calling it Phoropter, and you can see it here (best viewed with Chrome or Firefox on Android).
I could imagine this is what Pokémon Go is like if instead of creatures you collected mediocre designs.
Say you are looking at a London Underground map, and you notice the legend is completely color reliant. Looking through Phoropter you will see what the legend would look like to someone with protanopia, red-green color blindness.
You can then grab a snapshot with the camera icon and get a side-by-side photo that shows the difference in perception. You can now alert the transit authorities, or at least shame them on Twitter.
Once you get into it, it’s quite addicting. No design is above scrutiny.
I started this project thinking I can pull it off with CSS filters on a video element, but it turns out that is way to slow. So I ended up using WebGL via glfx.js. Tried to make is as progressive as possible, you can add it to your home screen. I won’t bore you with the details, check out the source when you have a chance.
There are still many more filters I can add later. In the meantime, open this in your mobile browser and,
