Separated PiP video windows are very minimal, with no borders, external controls, or other fluff to take in valuable screen realty.

You need to set your Enhanced Tracking Protection profile to Strict if you want Total Cookie Protection.

In December 2019, Firefox presented Picture-in-Picture mode– an additional overlay control on in-browser embedded videos that permits the user to separate the video from the browser. Once detached, the video has no window dressing whatsoever– no title bar, min/max/close, etc
.

As long as you leave the moms and dad tabs of existing PiP windows alone, you can continue separating extra videos from extra tabs.

Mousing over a detached PiP video window offers three in-window controls: a play/pause toggle, a reattach button that brings the video back into its original tab, and a plain X to close it instantly.

Overall Cookie Protection nerfs this misfeature by producing different “cookie jars” based upon the identity of the URL in fact present in the address bar. With this feature made it possible for, a Facebook script performing at contoso.com can still set and check out a Facebook cookie– however that cookie lives within the contoso.com cookie container only. When the same user searches facebook.com directly, later, Facebook can not check out, compose, and even find the presence of a Facebook cookie within the contoso.com cookie container, or vice versa.
This isnt a remedy against tracking, by any methods– for instance, it not does anything to prevent scripts from Facebook, Amazon, et al. from uploading data about your Web takes a trip to their own servers to profile you there. It at least keeps them from utilizing your own computer systems storage to do the filthy work for them.
If you want to enable Total Cookie Protection (and we actually, actually want Mozilla had picked a name that didnt initialize to TCP), youll initially need to set your Enhanced Tracking Protection to the Strict profile. To do so, click the guard icon to the left of the address bar (visible when searching any actual site, not visible on the blank New Tab screen) and click Protection Settings.
Total Cookie Protection has a few (apparently hard-coded) exemptions for third-party login providers– for instance, logging into YouTube with a personal Gmail account still enabled a check out to Gmail.com in another tab to instantly load the right inbox without the requirement to visit once again independently.
Mozilla alerts that the Strict Enhanced Tracking Profile might break some sites completely– and we think Mozilla– however in our own brief screening, we didnt experience any problems. We had no problem logging and loading in to Gmail, YouTube, Facebook, Twitter, and a number of other major websites.

Mozilla introduced PiP mode in Firefox 71. When mousing over a video playing in-browser, a control appears which allows you to remove the video into a different window.

Jim Salter In December, we reported on Firefox 85s introduction of cache partitioning– a plan that makes it harder for 3rd parties to figure out where you have and have not been on the Internet. Firefox 86 ups the ante again, with a plan Mozilla is calling “Total Cookie Protection.” In a nutshell, Total Cookie Protection limits the capability of 3rd parties to monitor your motion around the Web utilizing embedded components such as iframes or scripts. This avoids tracking cookies from Facebook, Amazon, et al. from “following you around the web.” In theory, cookies were currently strictly per-site– so contoso.com can not set or check out cookies coming from facebook.com, and vice versa. But in practice, if contoso.com voluntarily embeds active Facebook aspects in its website, the users internet browser treats those elements as coming from Facebook itself. That means Facebook can set the worth of a cookie while youre searching contoso.com, then checked out that worth once again later on when youre in fact on Facebook (or when youre on other, totally unassociated websites which also embed Facebook material).

Jim Salter Rigorous ETP is not on by default, and Mozilla cautions that some sites might fail to work completely with rigorous ETP and Total Cookie Protection. We had no difficulty on any of a number of significant sites.

Mozilla released Firefox 86 yesterday, and the web browser is now readily available for download and setup for all major operating systems, including Android. Together with the usual round of bug fixes and under-the-hood updates, the brand-new develop deals a couple of prominent functions– multiple Picture-in-Picture video-watching support, and (optional) stricter cookie separation, which Mozilla is branding Total Cookie Protection.
Taking Firefox 86 for a spin
Firefox 86 ended up being the default download at mozilla.org on Tuesday– however as an Ubuntu 20.04 user, I didnt desire to leave the Canonical-managed repositories simply to test the brand-new version. This is one circumstance in which snaps really excel– providing you with a containerized variation of an application, quickly installed but ensured not to mess with your “real” os.
As it ends up, Firefoxs breeze channel didnt get the message about develop 86 being the new default– the latest/default snap is still on construct 85. In order to get the brand-new version, I needed to snap refresh firefox– channel= latest/candidate.
With the new variation installed as a snap, the next step was in fact running it– which could be a lot simpler. The breeze produces a separate Firefox icon in Ubuntus launcher, but theres no method I know of to readily compare the icon for the system firefox and the brand-new snap-installed firefox. After some hit-and-miss disappointment, I finally dropped to the terminal and ran it straight by providing the totally pathed command / snap/firefox/current/ firefox.
Multi Picture-in-Picture Mode

Although Firefox 86 is the default download from Mozilla, the Snap store hasnt quite captured up yet. I required to snap refresh firefox– channel= latest/candidate in order to get build 86.

I set up Firefox 86 on my Ubuntu workstation using Snap to be certain I wouldnt inadvertently mess with my working system setup.

Advertisement PiP mode permits users who tile their windows– immediately or by hand– to watch stated video while taking in a bare minimum of screen real estate.
Firefox 86 presents the principle of multiple simultaneous Picture-in-Picture instances. Prior to develop 86, hitting the PiP control on a second video would just reattach the very first video to its parent tab and detach the 2nd. Now, you can have as numerous drifting, separated video windows as you d like– possibly turning any display into something similar to a security DVR display.
The key thing to realize about multi-PiP is that the moms and dad tabs must stay open– if you navigate away from the parent tab of an existing PiP window, the PiP window itself closes. As soon as I recognized this, I had no problem surrounding my Firefox 86 window with five removed, simultaneously playing video windows.
Total Cookie Protection Overall Cookie Protection in a nutshell– if Facebook (for example) sets cookies from within an iframe embedded in a tab open up to fuzzyslippers.com, it will not have the ability to check out that cookie from anywhere else.

In theory, cookies were already strictly per-site– so contoso.com can not set or check out cookies belonging to facebook.com, and vice versa. Overall Cookie Protection nerfs this misfeature by creating different “cookie jars” based on the identity of the URL really present in the address bar. With this feature enabled, a Facebook script running at contoso.com can still set and check out a Facebook cookie– however that cookie lives within the contoso.com cookie container only. When the exact same user browses facebook.com straight, later, Facebook can not check out, write, or even spot the existence of a Facebook cookie within the contoso.com cookie container, or vice versa.
If you want to make it possible for Total Cookie Protection (and we truly, really wish Mozilla had chosen a name that didnt initialize to TCP), youll first need to set your Enhanced Tracking Protection to the Strict profile.
