Mozilla halts Firefox 78 rollout – and then restarts it after fixing this search engine bug

Mozilla resumes rollout of Firefox version that drops support for connections over legacy TLS 1.0 and TLS 1.1 protocols.

Why Germany thinks Firefox is the most secure browser of all

Mozilla only released Firefox 78 at the very end of June, but it was forced to stop the release because search engines were missing from the browser. 

According to the bug report, Firefox 78 was missing all search engines as well as the list of one-click search engines. Additionally, auto-complete in the address bar was broken and search on the start page didn't launch a search.

As per Ghacks, the bug was bad enough for Mozilla to halt the Firefox 78 rollout. This issue affected Firefox Stable and Extended Support Release (ESR) when the browser was updated to the new version but not new installations of Firefox.

As of the past few hours, downloading the latest version of Firefox gives users Firefox 78.0.1.

Firefox 78 is an ESR, bringing enterprise organizations all the feature updates since Firefox 68, such as Service Worker and Push APIs, video autoplay blocking, and picture-in-picture support, according to Firefox Enterprise release notes.

Firefox 78 introduces new features to the Protections Dashboard, which provide users a summary of tracking protection, data breaches and password management. 

The new features let users track how many breaches have been resolved from the dashboard and to see if any saved passwords have been exposed in a data breach. 

Mozilla has fixed a usability issue with its implementation WebRTC for video calling in Firefox. Now, a screen saver won't interrupt WebRTC calls on Firefox, making conference and video calling in Firefox better. 

In this release, Mozilla has finally followed through with its plan to drop support for legacy protocols TLS 1.0 and TLS 1.1. It originally planned to drop support in Firefox 74, but this March, during the coronavirus pandemic, Mozilla re-enabled support to ensure people could still access critical websites, even if they hadn't been updated to TLS 1.2. Some 850,000 were still on legacy versions of TLS this March.  

"Sites that don't support TLS version 1.2 will now show an error page," Mozilla says in Firefox 78 release notes.

Also of note, Firefox 78 is the last major release with support for macOS versions 10.9, 10.10 and 10.11. Users on these platforms can run Firefox ESR 78.x to ensure they're supported through to the end of the year. 

Finally, Firefox 78 addresses seven high-severity security flaws, four medium-severity flaws, two low-severity ones, and a set of high-severity memory safety flaws.
