Version 9.0

Redesigned options page: each supported forge now has its own on/off slider, so you can enable only the platforms you use. "Enable all forges" turns every slider on (built-in and custom) in one click.
Custom GitLab/Gitea instances can now be added directly from the options page by typing a domain — or, as before, from the extension popup on any repository page.
Import and export your custom-forge whitelist as a JSON file, to share a common configuration across a team.
New lightgreen button when an archival visit is currently in progress for a repository (was previously mis-reported as a failed archival while the visit was still running).
New blue button when the extension cannot reach the Software Heritage API — a clear signal distinct from "not archived".
Outgoing API requests now identify themselves with proper Accept and User-Agent headers so they can be recognised by Software Heritage infrastructure.
Internal improvements: the extension no longer sends cookies on API calls (prevents spurious CSRF rejections when you are logged into archive.softwareheritage.org in the same browser).
