Just two days after releasing Firefox 140 to the Release channel, Mozilla is dropping a small update to address two bugs in version 140. Firefox 140.0.1 is now available for download, addressing crashes on startup and issues with contrast in the sidebar when using dark themes (black text appears on dark backgrounds, making it impossible to read).
Here is the changelog that Mozilla published in the official documentation:
- Fixed text contrast issues in the sidebar with some dark themes. (Bug 1971487)
- Fixed a startup crash experienced by some users caused by DLL injection. (Bug 1973947)
You can update Firefox to the latest version by heading to Menu > Help > About Firefox. Alternatively, you can get it from the official website or the Microsoft Store (Windows 10 and 11).
In case you missed it, Firefox 140 arrived on June 24. It introduced several important changes, including the ability to resize the pinned tab section when using vertical tabs (more upgrades are coming to the browser in this area), custom search engine support, tab unloading via right-click, various security fixes, and more. The update also removed the Pocket toolbar icon and the Pocket integration on the new tab page. Mozilla recently killed Pocket and Fakesport in order to focus more on its main product, the Firefox browser.
