Last week, Mozilla released Firefox 143, another big update for the browser with a bunch of new features and improvements. Now, several days later, developers dropped a small update that aims to resolve a single issue.
Version 143.0.1 is now available for download, and its sole purpose is to fix a tab-crashing issue that some users experience due to DLL injection, particularly with Trend Micro's tmmon64.dll. Here is what the changelog says:
Fixed a tab crash experienced by some users caused by DLL injection. (Bug 1872261)
And that is pretty much everything you need to know about Firefox 143.0.1. You can update your Firefox copy by navigating to Menu > Help > About Firefox. Alternatively, get the browser from the official website, or the Microsoft Store (if you are on Windows 10 or Windows 11).
In case you missed it, Firefox 143 was released on September 16. In the update, Mozilla introduced the ability to pin websites to the taskbar and run them as apps in UI-less windows. Also, it is now easier to pin apps by just dragging them, Copilot can now run in a sidebar, and Firefox can auto-delete files downloaded in Private Mode.
All those changes are available on supported Windows and macOS versions, while those still using outdated operating systems can stick with Firefox 115, which will remain supported for a little longer. Mozilla recently revealed its plans to expand Firefox 115 ESR support on Windows 7/8/8.1 and certain macOS versions, giving users a few more months of security updates. As for Windows 10, which will soon be out of support, it is too early to talk about mainstream browsing leaving the slowly sinking ship.
