The only site visited was Mozilla Add-ons, and that was after the first refresh while on the settings pages, which connected to these:gepus wrote: ↑2023-07-30, 15:59@Likestofish
As mentioned above, it's about 2 years I've last checked IceCat last time. (Since I'm mostly on Windows I lost interest for IceCat anyway.)
IMHO, actual build should be at 102.13.0. Ideally it should not lag excessively behind Firefox releases.
As for the connections you mention, I'm afraid that you get something wrong. Those connections seem to be generated definitively by sites you visit.
ssl.gstatic.com - both http/2 and http/3 as well as on DNS and socket, both TCP and UDP (these appear to have been connections to Google Safebrowsing, and perhaps something else as well)
mail.google.com - http/2 as well as on DNS and socket, just TCP
ocsp.pki.goog - http<=1.1 (of course, checking the vailidity of security certs, etc.)
After visiting Mozilla Add-ons, these connections appeared in about:networking:
xxx.googletagmanager.com (replaced www with xxx to prevent linking)
xxx.google.analystics.com ("")
cdn-statically.io
cdn.jsdelivr.net
No other site was visited.
It's unfortunate that yes, the IceCat build was a few point releases out of date, although I imagine some other repo may have up to date builds.
