The Firefox 59.0.2 maintenance release is here to address a high CPU and memory bug caused by third-party apps on various computers, though Mozilla didn’t mention if it affects all supported platforms. It also improves page rendering when hardware acceleration is enabled. It also fixes a bug that that would not allow users to use certain keyboard shortcuts, such as Ctrl+C, on websites that use those keys with the resistFingerprinting function enabled, and fixes an issue for users who want to reload their proxy settings if they configured an automatic proxy configuration URL.
