Mozilla Firefox 91 Arrives as the New ESR Series, Brings Back Simplified Printing

Filed under

It’s been a little less than a month since Firefox 90 landed with FTP support completely removed, and now Firefox 91 is already here with various improvements and bug fixes, including the simplified printing feature for a clutter-free print preview page (available under More settings > Format > Simplified in the Print Preview dialog). However, it should be noted that this feature doesn’t work on all pages.

Firefox 91 also improves the HTTPS-First policy for Private Browsing windows to allow them to make all connections to a website secure (HTTPS), as well as to fallback to insecure (HTTP) connections only when a website doesn’t support secure connections.

  • Firefox 91 Released As New ESR Base, HTTPS First Policy For Private Mode

    Firefox 91 is the newest "Extended Support Release" (ESR) meaning that it's maintained longer than the normal release cycle and thus a popular target for enterprises and other organizations. Firefox 78 is the current ESR release to this point, thus many changes between then and now for those that stick only to such releases.

  • Mozilla Security Blog: Firefox 91 introduces HTTPS by Default in Private Browsing

    We are excited to announce that, starting in Firefox 91, Private Browsing Windows will favor secure connections to the web by default. For every website you visit, Firefox will automatically establish a secure, encrypted connection over HTTPS whenever possible.

  • Mozilla Security Blog: Firefox 91 Introduces Enhanced Cookie Clearing

    We are pleased to announce a new, major privacy enhancement to Firefox’s cookie handling that lets you fully erase your browser history for any website. Today’s new version of Firefox Strict Mode lets you easily delete all cookies and supercookies that were stored on your computer by a website or by any trackers embedded in it.

    Building on Total Cookie Protection, Firefox 91’s new approach to deleting cookies prevents hidden privacy violations and makes it easy for you to see which websites are storing information on your computer.

    When you decide to tell Firefox to forget about a website, Firefox will automatically throw away all cookies, supercookies and other data stored in that website’s “cookie jar”. This “Enhanced Cookie Clearing” makes it easy to delete all traces of a website in your browser without the possibility of sneaky third-party cookies sticking around.

    August is already here, which means so is Firefox 91! This release has a Scottish locale added and, if the ‘increased contrast’ setting is checked, auto enables High Contrast mode on macOS.

    Private browsing windows have an HTTPS-first policy and will automatically attempt to make all connections to websites secure. Connections will fall back to HTTP if the website does not support HTTPS.

    For developers Firefox 91 supports the Visual Viewport API and adds some more additions to the Intl.DateTimeFormat object.

Firefox 91 Available to Download, This is What’s New

  • Firefox 91 Available to Download, This is What’s New

    Mozilla Firefox 91 is now available to download for Windows, macOS, and Linux.

    What’s new? A more responsive web according to Mozilla, who say Firefox 91 offers a 10-20% improvement in response time to ‘most’ user interactions. Whether or not it is that pronounced for most users is moot since any improvement, however marginal, is always welcome.

    Also improved is Firefox’s Total Cookie Protection feature. The bods working on the browser say they’ve added “comprehensive logic for clearing cookies that prevents hidden data leaks”. It also makes it easy for Firefox users to discern which websites in particular are storing information locally.

    Using incognito (sorry, ‘Firefox Private Browsing’ mode)? The browser now tries to ensure all connections to websites use HTTPS, and only default to non-secure connections if absolutely not supported.

    Finally, those who use the browser on Windows 10 can now login to Microsoft accounts using Windows single sign-on credentials added in the underlying OS; while macOS users making use of OS accessibility settings will appreciate Firefox switching its ‘High Contrast Mode’ on automatically when necessary.

Firefox 91 is Here and Pushes Privacy

  • Firefox 91 is Here and Pushes Privacy with Enhanced Cookie Clearing

    Firefox 91 is the seventh major browser update in 2021. Let’s cover some of the notable changes in this new browser update.

    Firefox is one of the few remaining browsers with its own rendering engine. Firefox 90 arrived last month with new rendering features and new update system, and now Firefox 91 is starting to roll out.


    With the release of Firefox 91, Mozilla has introduced a bigger hammer for smashing the cookies that websites, advertisers and tracking companies can use to record your online behavior. The new feature, called enhanced cookie clearing, is designed to block tracking not just from a website, but also from third parties whose code appears on the site.

  • The Talospace Project: Firefox 91 on POWER fur the fowk

    Firefox 91 is out. Yes, it further improves cookie isolation and cleanup, has faster paint scheduling (noticeably, in some cases), and new JavaScript and DOM support. But for my money, the biggest news is the Scots support: aye, laddie, noo ye kin stravaig the wab lik Robert Burns did. We've waited tae lang fur this.

    Anyway, Firefox 91 builds oot o the kist oa, er, Firefox 91 builds out of the box on OpenPOWER using the same .mozconfigs for Firefox 90; I made a wee change to the PGO-LTO patch since I messed up the diff the last time and didn't notice. The crypto issues in Fx90 are fixed in this release.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
