Release notes for 3.2.1
- Adds support for showing pages loaded over HTTP/3 (including actual protocol version) in Firefox 88+
- Adds support for showing pages loaded over HTTP 1.x versions
- "Partial" HTTP/2 state is no longer shown, since the addon now shows you the specific HTTP version used rather than simply whether the page was loaded over HTTP/2 or not.
- Updated the colored page action icons so that they will appear correctly when Firefox's dark theme is applied. HTTP/2 and SPDY are now both represented using the blue icon, and HTTP/3 is represented in green.
