Interesting! My negative experience with Firefox was with this 6 year old feature request relating to container colors. [0] They have hardcoded some colors & icons (6 or 8 I think?) as possible options. The problem is: If you have more than half a dozen of Gmail accounts that you want to containerize (e.g. for client work), it is really hard to keep them apart at first glance. Compare this to Google Chrome, where you can choose the browser color for each associated Gmail account individually. I tried to manually extend & build it for myself, but the codebase relating to that was just a mindfuck to work on...

In Fixing a bug in Google Chrome as a first-time contributor
the opposite is true, too, since "Clear History" in Chrome Profiles behaves correctly and (AFAIK) is scoped just to that Profile unlike our container friend: https://github.com/mozilla/multi-account-containers/issues/3... I still use them because combined with https://addons.mozilla.org/en-US/firefox/addon/open-url-in-c... ( https://github.com/honsiorovskyi/open-url-in-container ) is a game changer for my workflow but it does make me sad that issue has been open for so long

flurdy·Feb 13, 2023Recommendation phrase
I Love the Multi account feature. And its related extentions Google and facebook containers. And especially the Temporary Container extension. [1] Only hassle I have is that I sometimes have to disable the google one if a site requires google auth but is in a non google container. Redirection wont work otherwise. Only temporarily until auth has finished. Also I like the integration with Mozilla VPN per container. But I wish they would support disabling the VPN for some or in reverse only enable tunneling for some containers. There was a an open issue for that.

In Multi-Account Containers
Have you seen the browsing containers^1, including the self-destructing ones? I'm 100% not trying to lobby you out of private browsing, just wondering if you were using the mode that best fit your needs Also, be aware that (unless something has radically changed) all private windows share state with one another, which to the very best of my knowledge isn't true for the browser containers 1: https://addons.mozilla.org/firefox/addon/multi-account-conta... and https://github.com/mozilla/multi-account-containers#readme
In Firefox Private Browsing mode upgrade
I used to have multiple chrome profiles I'd run at once, but this feature works so nicely & makes having work, banking, & other profiles nicely integrated but separate. It's made Firefox my primary browser! The main pain is that I use github on multiple profiles, & cant make github.com/company/* go to a certain container. There's a ~5 year old issue for expanding matching support[1]. Some days I think about trying to hack on it. [1] https://github.com/mozilla/multi-account-containers/issues/4...
In Firefox Extension – Multi-Account Containers by Firefox
While they often are, there’s no rule that web apps have to be a privacy nightmare. Thanks to Hacker News¹, I recently came across Learn systemd by example². The site itself is hosted by Hetzner, a German hosting provider that take user privacy seriously³ and uses Cloudflare as a privacy-conscious CDN⁴. The only third-party resources it uses are Google fonts. Users of uMatrix⁵ or uBlock Origin⁶ can easily block these resources and the web app works perfectly fine without them. I’d also use Wordle itself as an example of a reasonably user-privacy friendly web application. The only third-party resources it uses is Google Tag Manager (which is blocked by default by uMatrix). I use Firefox with a number of web extensions (Firefox Multi-Account Containers⁷, Decentraleyes⁸, uMatrix, uBlock Origin, Privacy Redirect⁹). These all provide me, an e

nd-user, much greater control over my online privacy than I’d have with a mobile app. I’ve also recommended Decentraleyes and uBlock Origin to non-technical friends as extensions they can install and not worry about configuration. 1. https://news.ycombinator.com/item?id=30071240 2. https://systemd-by-example.com/ 3. https://www.hetzner.com/legal/privacy-policy 4. https://www.cloudflare.com/privacypolicy/ 5. https://github.com/gorhill/uMatrix 6. https://github.com/gorhill/uBlock#ublock-origin 7. https://github.com/mozilla/multi-account-containers#readme 8. https://decentraleyes.org/ 9. https://github.com/SimonBrazell/privacy-redirect
In Play Wordle from Your Terminal
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.
