sadly, seeing @ firefox on the federated timeline doesn't allow to distinguish it as a Lemmy group, especially for all the people who don't know about it. It appears just any other account, or looking a bit deeper, like any "group" account that diverse technologies allow on the microblogging side of the fediverse.
(Also nothing to guess English is mandatory.)
I guess on the Lemmy side, the fact that the post is from Mastodon microblogging is not very clear neither?
Lemmy is a Fediverse software for community-based discussion, something similar to reddit.
When you tag Lemmy communities via Mastodon, you submit your toot to respective community as a post. That's why people are a bit confused here.
Also, first line on your post transforms to a title on lemmy, and it looks like this: "Sur [#iOS](https://mastodon.social/tags/iOS), le navigateur [#chrome](https://mastodon.social/tags/chrome) de [#google](https://mastodon.social/tags/google) va maintenant permettre d'avoir la barre d'". Lemmy doesn't use formatting for titles.
