Mozilla has rolled out a small patch for the recently released Firefox 137. Version 137.0.1 is now available for download and fixes three critical bugs. Two of these bugs caused the browser to crash on Windows, while the third bug affected the behavior of folder shortcuts.

Mozilla says the update resolves a crash issue on Windows systems with Qihoo 360 antivirus software installed, as well as fixes “occasional” startup crashes. A bug with folder shortcuts that prevented files inside folders from being selected has also been fixed in this update.

Here is the official changelog:

Version 137.0.1, first released to Release Channel users on April 8, 2025

– Folder shortcuts on Windows were being incorrectly treated as files during file uploads, making it impossible to select files in the target folder. (Bug 1958222)

– Windows users were experiencing crashes while downloading files when users had Qihoo 360 Total Security antivirus installed on their systems. (Bug 1958112)

– Fixed an occasional crash during startup. (Bug 1958293)

In case you missed it, Mozilla released Firefox 137 on April 1. This was a major update that added many sought-after features — like tab groups, a new address bar (which now also works as a calculator), HEVC playback on Linux, PDF signing, and more. The full release notes for version 137 are available here.

You can update Firefox by going to Menu > Help > About Firefox. Alternatively, you can also download it from Mozilla’s official website or the Microsoft Store (if you’re on Windows 10 or 11).
