Mozilla releases Firefox 147.0.1 with fixes for ChatGPT and more

Mozilla has released a minor update for the recently launched Firefox 147.0. Today's release under version 147.0.1 does not contain any major changes or new features. It addresses several bugs, including compatibility issues with certain websites like ChatGPT, empty directories on Linux, and incorrect page rendering due to time format bugs.

Here is the changelog:

• Fixed compatibility problems with websites that use the new Compression Dictionaries technology, such as ChatGPT, by temporarily disabling the feature. (Bug 2010712)
• Fixed an issue where an unnecessary empty directory was created on Linux systems. (Bug 2001887)
• Fixed an issue where time formats could cause certain websites to display incorrectly. (Bug 2010411)

You can update Firefox by heading to Menu > Help > About Firefox. Alternatively, download the browser's installer from the official website or the Microsoft Store (if you are on Windows 10 and 11).

In case you missed it, Firefox 147 was released earlier this month with a couple of new features, including automatic picture-in-picture when switching tabs, WebGPU support on Apple Silicon Macs, video playback improvements on AMD systems, keyboard shortcut customization, and more. You can find the release notes in our dedicated article.

In other news, Mozilla recently got a new CEO. Anthony Enzor-DeMeo is now at the company's helm, and he promises to make it the "world's most trusted software company." At the same time, Mozilla is facing big pushback from users who do not like the company's efforts to inject more AI into the browser.
