From PC World: With Firefox’s latest version 150 update for Windows, macOS, and Linux, Mozilla has introduced few genuinely new features but some noteworthy improvements. The split view is easier to use, the built-in PDF viewer is increasingly evolving into a PDF editor, and the developers have once again fixed a host of vulnerabilities.
Mozilla plans to release Firefox 151 in four weeks on May 19th, 2026.
The split-screen feature introduced in Firefox 149 has been improved. You can now right-click on any link and select “Open link in split view,” and you can also swap the two halves of a split window.
The built-in PDF viewer/editor can now also reorder PDF documents and copy, paste, delete, or export pages. You can also copy and save images contained within PDFs. The ability to merge multiple PDF documents into a single file is expected to follow soon.
