Discover the New Firefox Profiler

UA2.114 (Baudoux)
Nazım Can Altınova
Using a profiling tool help developers to get detailed information about the execution of their application and allow them to understand the behavior of it. The Firefox Profiler is a profiler that is built into Firefox. It has tighter integration with Firefox than external profilers. It can provide more information and insight into what the browser is doing. It can also show the memory usage and Firefox internal code execution. During the talk, I will be explaining, how to capture a good profile and how to analyze profile data. I will be sharing Firefox Profiler specific features like memory tooling, single tab/advanced view and how to use them. I will also be sharing the future of Firefox Profiler!

Web applications are more popular than ever and users expect more from a web application. Unfortunately, they are using applications more frequently from low powered devices, which strains your application’s performance. Managing application performance can be challenging as modern applications have many dependencies and their complexity can hide the issues.

Using profiling tools to look for potential bottlenecks can significantly reduce the number of problems in your application. It helps you to get detailed information about the execution of your application and it allows you to understand the behavior of it.

The Firefox Profiler is a profiler that is built into Firefox and is available at https://profiler.firefox.com/. It has tighter integration with Firefox than external profilers. It can provide more information and insight into what the browser is doing. Aside from understanding the execution of a web page, it can also show the memory usage and Firefox internal code execution.

The intended audience is all web developers and people who want to contribute to Mozilla by helping us analyze the Firefox performance issues by capturing profiles and filing bugs.

How the Firefox team changed how we thought about shipping features and replaced a process biased towards those who had the loudest voices and the luxury of time with a process that is more inclusive and allows us to reduce risk to Firefox users when we ship.

We take a look at Thunderbird's roadmap for the future with Ryan Sipes, Thunderbird's Community and Business Development Manager, and break down what the project has planned for 2020 and beyond. Despite some of the Internet saying that Thunderbird was on its deathbed a few years ago, the team has been able to put together a lot of resources and developers to create a better Email client for the world. And we have bigger plans for the coming years.

The web is pretty much present in everyone's life nowdays. But is it really for all? How are we making it a smooth usage for those with disabilities, for those with reduce time and internet connection? Or even more further, for those that just use the web for the first time? Let's learn a bit how the devtools from Firefox can help us improve everyone's experience without much of a sacrifice on our end.

In 2019, Mozilla's Open Innovation and WebCompat team joined forces to improve the process of gathering web compatibility issues. One of the experiments was to introduce machine learning capabilities in the triaging process and automate some steps. This talk is about the early steps and how we got some hands on experience with machine learning, what we've achieved so far and potential next steps.

WebAssembly System Interface (WASI) is the new brilliant community effort at standardising the use of WebAssembly (Wasm) outside the browser environment. Initiated by Mozilla, now under the umbrella of Bytecode Alliance, WASI has the potential to revolutionise the way we think about the "build once, run anywhere" in a truly secure manner. But could WASI also lend itself to a task of running any code within a network of distributed, untrusted nodes such as BOINC or Golem Network, and ensuring ...
