What Hacker News says

9 sources
There's no obvious reason to grant the nativeMessaging permission during extension installation for an optional feature, nativeMessaging can be declared as an optional permission since Firefox 87 [1], and Firefox Multi-Account Containers 8.0.2 only supports Firefox 91 or newer. There could be a bug related to declaring nativeMessaging as an optional permission, though that is not mentioned in the pull request [2], so this was probably an oversight. EDIT: the minimum supported version was bumped to Firefox 91 in a subsequent PR apparently not for technical reasons, but just to follow guidelines [3], and then they forgot to reevaluate the need for the new default permission before a release.

In Multi-Account Containers to “Exchange messages with programs other than Firefox”
I wish they fixed the long standing, annoying sync bug that makes Firefox download 7000+ containers every once in a while. Some of us hosed our sync accounts in one way or another (through the container duplication bug in m-a-c itself [1] or the temporary containers extension [2]) and it's impossible to recover - once you reach the storage quota on the sync server, the sync server refuses all write operations and delete call apparently counts as a write.

In Multi-Account Containers to “Exchange messages with programs other than Firefox”
Tab Containers are a nice feature, but aren't quite there yet. For example, history is currently not isolated per container: https://github.com/mozilla/multi-account-containers/issues/1... https://bugzilla.mozilla.org/show_bug.cgi?id=1283320 Multiple browser profiles also let me have one profile for work, another one for personal stuff, and yet another one only with stuff like vue/react/svelte dev tools and remote debugging enabled, and _then_ decide which one to open at any given time. This instead of opening every container at once, or something like selectively opening a bunch of bookmarks manually into a specific container (I use buku to manage and sync my bookmarks too, so no tab container support there).
In Firefox 93
I switched to FF on Windows 10 as my daily driver a year and a half ago in order to adopt a multi-account container workflow. MACs aren't perfect [1] and overall I definitely sense that FF is not as power-efficient as Chrome, especially when in a Meet call, but overall I'm very happy with it and the power thing is not a huge issue if I'm sitting wired in all day anyway. [1]: My criticisms: https://github.com/mozilla/multi-account-containers/issues/1...
In Mozilla plans to remove the Compact Density option from Firefox's Customize menu
I agree. As someone who works with numerous customer environments this extension is critical for my productivity. Having a different profile (ie Chrome style) is nowhere close. If the container re-ordering patch[0] would be implemented it would be perfect, but it seems to be stuck in limbo. If Brave implemented this and did it right (with sorting & reordering) I would consider switching. [0] https://github.com/mozilla/multi-account-containers/pull/160...
