Could you summarize the request to update KB articles for Nova Fx155? Nightly is at version 154. I don't have access to the google doc spreadsheet.

I checked in Firefox 155, released Sept 1, 2026 (Windows 11 en-US) and the browser.nova.enabled preference is still "false" by default in about:config. Has this been moved to a later release?

Regarding compact mode (as mentioned in https://connect.mozilla.org/t5/discussions/sharing-more-about-project-nova/m-p/125996) there is no "Window density" section in Appearance settings.

I checked in Firefox 156 released Sept 15, 2026 (Windows 11 en-US) and the browser.nova.enabled preference is still "false" by default in about:config. However, in Firefox 157 Beta, browser.nova.enabled is "true" by default and Appearance settings show the new Window density section (screenshot attached). The KB article Compact mode workaround in Firefox will need an update for fx157.

Update the bug summary to change Fx155 to Fx157?
See bug 2073229 Description • 2026-09-17 15:14 EDT (quote) Regarding Nova, we plan on updating the images in general Private Browsing KB article shortly after Nova lands in Release 157 (early October) since it's only a visual refresh.

The Use Firefox in Full Screen mode and Use tabs to organize lots of websites in a single window articles were updated by Flavius with new images using {for fx157} markup with the comment, Bug 2048963. Images changed per Firefox Nova:

• https://support.mozilla.org/en-US/kb/tabs-organize-websites-single-window/history

Thanks for the catch. Summary updated to 157.

Yes, updates still needed for Compact Mode article and Theme Selection (draft in spreadsheet)

The update to the Sponsors on the home page and New Tab page article for fx157 added Nightly images. They should be replaced with Firefox images. See discussion: https://support.mozilla.org/en-US/kb/sponsor-privacy/discuss/15501

We agreed internally to use Nightly screenshots so we can have the relevant SUMO articles ready for the Nova launch. Once the Nova updates are available in Firefox, we’ll replace the Nightly screenshots with Firefox ones. Thanks for understanding!

[Alice Wyman]

I don't understand. Nova updates are available in Firefox 157 beta so why use Nightly images?

Your revision to add Nova images in the Sponsors on the home page and New Tab page article erroneously changed screenshots in the ""Sponsored stories" section for fx156 and below and added an incorrect screenshot for fx157, showing "Sponsored shortcuts" highlighted instead of "Sponsored stories". See https://support.mozilla.org/en-US/kb/sponsor-privacy/history - I submitted a revision to correct those changes. Can you review?

Thanks for pointing it out. I deferred it and corrected it with the right screenshot.

Your new revision to the Sponsors on the home page and New Tab page article left out my changes and only corrected the "Sponsored stories" screenshot for fx157. The ones for fx156 and below still have "sponsored shortcuts" images. I submitted another revision with corrected screenshots for fx156 and below. See https://support.mozilla.org/en-US/kb/sponsor-privacy/history Can you review?
^EDIT: Thanks for approving my revision (I marked it RFL).

Oh, I wasn't aware of this. I'll use beta screenshots directly, then. Thanks!
