Select your browserįiremin will work with any browser, in fact, it will work with any program. To start, if you have not done so, install Firemin and open it by double clicking on the tray icon, or right-clicking on the tray icon and choosing Open Firemin. I will be using Google Chrome as an example, but Firemin can be used with literally any executable. In this article, I show how to select your preferred browser and use Firemin to stop those pesky memory leaks. Using FireminĮven though we created the new Firemin to be easy to use, we realized that some users still do not know how to use Firemin efficiently. The method Firemin uses to decrease Firefox memory usage is not proven and the debate over if it works or not will go on until the end of time, but the logic remains if it works for you, use it and if it does not, don’t use it. Firemin runs the clean memory API call a few times per second. However, It is our opinion that Windows does not clean out memory as often as we would like it to. You could argue that this makes Firemin unnecessary, and you would be spot on. Windows will also periodically scan running processes and tell them to release their unused memory. All I did was tweak our Memory Booster a little and applied it to Firefox and this solved the memory leak issues. Simply put, Firemin will attempt to eliminate Firefox memory leaks and decrease the amount of memory Firefox uses. In a memory leak, you’ll see the memory usage keeps increasing the longer the program is open/in use and this is exactly what happens with Firefox. It’s quite normal for Firefox to be sucking up over 250 MB of memory right off the bat. Because of this Firefox was using over 3 GB of memory after a few days. Programs on my computer can stay open and run for days or even weeks, and Firefox is no exception. Although Firefox memory usage improved a little over the last few years, it still uses a lot of memory a little more than we feel comfortable with.

Please let us know what you think about these changes in a comment on this post, and if you’ve found something broken, report it in a Bugzilla ticket. We’re very excited to be delivering this performance and stability improvement to you all, and we’re eager to hear your feedback and answer questions. This upgrade shipped for Android last year in the Firefox 102 release, for Windows and Linux in the Firefox 112 release, and today it arrives on MacOS, which completes our rollout to all Firefox platforms. For some of the worst use cases - like pages with very large tables - Firefox now performs up to 20 times faster, and we’re clocking other very large pages at 10 times faster! However, even for the most everyday actions, like opening and closing a Gmail message or switching channels in a Slack window, the performance is 2 to 3 times better. This blog post by accessibility tech lead Jamie Teh provides more context and technical details on the project, but the largest impact you’ll notice immediately is speed. We were inspired by Chrome’s approach and extended it to improve Firefox’s accessibility performance Firefox now provides a cache of all tab and browser UI content to screen readers in the browser’s parent process, where it can be used quickly and very easily. With multiple isolated processes, screen readers had to do a lot of expensive work to retrieve and relay content to users. Today, with the release of Firefox 113, those improvements are available to all Firefox users on Windows, Mac, Linux, and Android.īrowsers are more complicated today than when Firefox’s accessibility engine was first designed, and the most significant overall change has been the move to security-isolated, multi-process architectures. This upgrade changes the way things work in Firefox’s accessibility code so that screen readers and other assistive technologies have fast access to the content they need. Continued investment in the old architecture simply wasn’t going to be enough to maintain a competitive browser so we began planning a re-write, which became a project called Cache the World. The Firefox accessibility engineers remedied much of that performance regression in the late twenty-teens, but by 2020 they’d done all they could to keep up. In some ways, our screen reader performance actually regressed with the architecture changes that Quantum delivered. Unfortunately, Firefox Quantum didn’t improve performance for people who use screen readers and other assistive technology. About five years ago Mozilla shipped Firefox Quantum, an upgrade that included significant performance improvements for most Firefox users.
