Firefox 94.0.2: first Microsoft Store-specific update, released for all platforms
Mozilla Firefox 94.0.2 will be released today. The new version of Firefox addresses a single issue in the Microsoft Store version of Firefox. While that is the case, it is released on all platforms, including Linux, Mac and Windows.
The Microsoft Store version of Firefox updates automatically through the store itself. Non-Store versions of Firefox will receive the update automatically as well. There is no rush to install it unless Firefox was installed via the Microsoft Store.
Mozilla launched Firefox on Microsoft's new Store, which welcomes regular desktop applications now, recently. The Store is available natively on Windows 11; Microsoft started to roll out the new Store for Windows 10 as well.
Back to Firefox 94.0.2. The release notes list a single issue that is fixed in the new Firefox update.
Improved hangs experienced by users of assistive technology such as NVDA when installing Firefox through the Microsoft Store
E10s a11y depends on a COM component (AccessibleHandler.dll) which has to be registered in the registry. Without this component, a11y will work, but it will be unusably slow, possibly unreliable and OOP iframes won't work with the JAWS screen reader.
The issue is caused by a missing component, which causes responsiveness to be very poor in the beginning when using assistive technologies such as NVDA screen reader in the Firefox version for Microsoft Store.
The issue will be fixed later on with the release of Firefox 94.0.2. Mozilla is reworking the entire system to remove dependencies, but it is not ready yet for release.
Firefox users on other platforms should feel no rush to install the new Firefox 94.0.2 release immediately, since it is addressing a Microsoft Store specific issue.
The fix is important for users of assistive technologies if the Microsoft Store version of the browser is used. It makes sense to release the update as a patch instead of waiting for the December release of Firefox 95.Advertisement
