KB content update/ new content

Please summarize the request, emphasizing any user-facing changes. Include historical context or background information if it helps users understand the new features or changes. [REQUIRED]

Per https://blog.mozilla.org/futurereleases/2025/09/05/firefox-32-bit-linux-support-to-end-in-2026/ we'll be ending support for 32-bit linux with firefox 145. As users on that platform check for updates we'll need a sumo page to explain the situation, that the update server can point them at.
This is similar to https://support.mozilla.org/kb/your-hardware-no-longer-supported from when we dropped support for older CPUs, https://support.mozilla.org/1/firefox/52.0/win/%LOCALE%/xp-eol (i.e. https://support.mozilla.org/en-US/kb/end-support-windows-xp-and-vista) from when we ended support for old windows versions, or https://support.mozilla.org/kb/firefox-osx from when we dropped support for old macos versions.

##Are the user-facing changes mentioned above for the production release, or is the feature/change experimental/ beta? (Production, Experimental or Beta) [REQUIRED]
Production

Are the new features or changes region-specific? Are they going to be released in a gradual rollout? [REQUIRED]

No

Please indicate if this is an on- or off-train release [REQUIRED]

Firefox desktop v145

What is the anticipated release date? [REQUIRED]

November 11, 2025

Does the content need to be published prior to the release date? If so, when? [REQUIRED]

Ideally before October 14 so we can use it on beta as well.

Does the content need to be localized in any languages outside of EN-US? If yes, please indicate which languages. [REQUIRED]

Yes.

Please include any related JIRA/Github/Bugzilla tickets, documentation, demos or practical use cases. [REQUIRED]

I've got a draft for the page at https://docs.google.com/document/d/1QcXG9mzfoRX1ZLRl9-JYmVfMe72PCjde7QIx1DOmsLA/edit?tab=t.0

Please include links to any design assets, visuals, figma files, etc. [REQUIRED]
