Add images to PDFs

Firefox already supported editing PDF files, and you could edit, add, or subtract text from files. Now, with Firefox 119, you can also insert and edit images in PDF files. Additionally, it also allows you to add Alt text when adding images to PDF files.

Import supported extensions from Chrome

If you plan on moving your default browser from Chrome and switching to Firefox, then you can also import your browser extensions! This way, you do not have to manually install the same extensions on the new browser.

Of course, the extensions should be supported on Firefox as well.

Other features and improvements

Some other changes have also been made, which include:

  • Media sniffing is now disabled for top-level documents as type “application/octet-stream.”
  • Firefox now supports partitioning of Blob URLs as part of its total cookie protection.
  • Encrypted Client Hello (ECH) is now available.
  • The CSS attr() function now supports a fallback parameter.
