Firefox 88.0 is out today as the latest version of Mozilla's web browser.

In addition to beginning the QUIC and HTTP/3 roll-out, Firefox 88 has a number of other improvements in tow. Firefox 88 now supports PDF forms that have JavaScript embedded in PDF files... Apparently JS in PDF is a thing for form validation and other interactive elements. Firefox 88.0 on Linux also now supports smooth pinch-zooming using a touchpad, various security improvements, and FTP support has been disabled ahead of its complete removal coming in the near future. The complete removal of FTP support is expected to happen for Firefox 90.
