Firefox 160 released today with some new features.

A new “Mini Window” option lets you move a tab or select a portion of a web page to an always-on-top window, so you can keep an eye on it while browsing. The feature is in beta and Mozilla invite feedback on it.

Mozilla say the feature is “useful when you’re multitasking and need to keep a few sources of information in view at once” – think Picture-in-Picture mode, but to see sections or entire web pages, basically.

Using it is easy. You can right click a tab, mouse into the Move Tab menu and choose Move to Mini Window to punt an entire page to a dedicated floating, resizable and compact window with address bar and navigation buttons that auto-hide.

Or customise the toolbar and add the Mini Window icon. Pressing this on a page gives you the choice of sharing the whole tab or just a portion.

You can also “PiP” part of a page using right-click > Move Section to Mini Window. This prompts you to draw out the section you want to pop out, and then do so.

Picture-in-Picture mode also gets a boost in this update. PiP windows now have a button to adjust playback speed, from 0.25x to 2.0x, depending on the source. The speed button only shows if the player window is large enough to have the button on show, though.

And if you regularly copy words to your clipboard with the intent to search, Firefox’s address bar context menu now reads “Paste and Search” for plain text, with “Paste and Go” reserved for URLs only.

Other changes in Firefox 160:

Drag history entries from the sidebar to the tab strip to open them

Saving pages as PDF makes MathLab content screen-reader friendly

Fixes improves visual contrast between domain name and the rest of the address bar, resolve minor text selection and cursor placement quirks using touch-input and nixes some small freezes affecting sign-in on intranet sites with NTLM or Kerberos.

Plus, as ever, a fresh crop of security fixes.
