Firefox 103 and Firefox 102.1 ESR will be released later today. The new Firefox 103 Stable release fixes security issues, improves performance and the browser's picture-in-picture mode, adds new toolbar keyboard access https://www.ghacks.net/2022/07/26/firefox-103-improved-toolbar-access-performance-and-more/
Release notes for Firefox v103.0.0 are now posted at https://www.mozilla.org/en-US/firefox/103.0/releasenotes/.

Note that Firefox v103.0.0 finally added Total Cookie Protection to the Standard option of my Enhanced Tracking Protection at Settings | Privacy & Security | Browser Privacy | Enhanced Tracking Protection | Standard. This feature started rolling out to Firefox a few months ago but was only activated today in my Firefox browser. See the Mozilla support articles Introducing Total Cookie Protection in Standard Mode and Total Cookie Protection and Website Breakage FAQ as well as the discussion in Alex5723's 24-Jun-2022 Firefox Rolls Out Total Cookie Protection as Default to All Users Worldwide in the AskWoody forum.
I also checked at Settings | Privacy & Security | Address Bar and confirmed that I still don't have the Firefox Suggest feature that started rolling out to US customers in Firefox v93 (see my 07-Oct-2021 post <here>). I live in Canada and suspect that's why I haven't seen this feature yet, which is fine by me. If it ever shows up in my Firefox browser I'll just disable it anyway.
