Both pages list Chrome and Firefox, the english version also lists Opera. Also the english version lists since which version of chrome, opera, firefox U2F is supported.
Chrome: v38 Opera: v40 Firefox: 57.
This seems to be old information. The U2F Wikipediapage says that Chrome was the first in 2014 but Firefox supports U2F since update 57. Also it might make sense to list the Opera browser as supporting U2F although its base is Chrome since that help the average user who does not know this.
Also 4 years isn't new anymore ;)
