A corrective release of Firefox 125.0.3 is available, which resolves several issues:
- An error has been fixed that caused some users to experience spontaneous opening of new tabs with the URL 'https://0.0.0.1' in the address bar after upgrading to Firefox 125. This effect was observed only on the Windows platform. An investigation revealed that the tabs appear when attempting to launch another instance of Firefox from the command line while Firefox is already running. Users who encountered this issue, and did not initiate any new instances of Firefox themselves, are advised to check their systems with antivirus software as such activity may be due to malicious programs.
The appearance of a tab with the address 'https://0.0.0.1' was caused by a bug in the 'Application Launch Prefetcher' handler. In the Firefox 125 branch, when starting an additional process, the method nsWinRemoteClient::SendCommandLine is used, adding the option '/prefetch:1' to the command line, which during parameter parsing gets converted to '-prefetch 1'. The '-prefetch' parameter is subsequently ignored, and the remaining '1' is interpreted as a URL to open (equivalent to launching 'firefox.exe 1'), which leads to the attempt to open the site 'https://0.0.0.1'.
- In the Linux builds, a text corruption issue occurring during drag-and-drop of text containing Unicode characters has been resolved.
- An error in checking argument size (arguments.length) within a generator or async function has been fixed, which led to the passing of an empty object.
- The issue with incorrect input focus handling in elements has been resolved.
