Mozilla is working on showing a new User interface for its browser on Startup to give users a visual indication that Firefox is running on slow machines. The thing known as Skeleton UI is much noticeable in Nightly on Windows 10. The first window you see when Firefox loads is the new interface all about.
Generally, when you click on the Firefox icon on the desktop,
- you should wait for 19 seconds for visual indication that you’ve launched Firefox
- after that, you see a blank window
- Wait for 3 seconds for browser Chrome to appear
- Wait for 8 seconds to see about: home loading.
Mozilla thinks 9 seconds delay can be avoided by loading early skeleton UI.
“This is a feature which allows us to create the first window and populate it with a non-interactive placeholder before we load xul.dll. On some systems, this can mean we can give visual indication of Firefox launching as much as 15 seconds sooner than normal (loading xul.dll can take a while).” Firefox Engineer Doug Thayer said in a thread
“We’re hoping this could be a big win for users who experience slow startups, and we also hope it will improve the overall snappiness of startup even on fast systems.”
Enable or disable Skeleton UI in Firefox
- Launch Firefox
- Visit about:config
- Click on “Accept the Risk and continue”
- Search for skeleton, toggle “browser.
startup. ” pref to True.preXulSkeletonUI
As of writing this article, Mozilla has enabled it by default in Firefox 86 (Nightly) on Windows 10. You”ll notice the Skeleton UI when you restart Firefox for the next time.
Firefox’s Skeleton UI is currently available to the Windows platform, for now.
