The ability to use plugins easily on mobile phone. That's why I choose firefox

Except they limited it with recent Firefox Mobile "updates" or "redesigns". AFAIK the last fully-featured FF Mobile on Android is 68.12.0. I have tried the most recent FF Mobile couple of weeks ago and there were only a small subset of add-ons supported and still no about:config.

I'm confused here about two things, and can't find any answers in the comments.

1) How is this different from a regular Firefox container you use for Facebook?

2) Firefox containers are essentially the same as Chrome profiles, right?

I'm just trying to figure out what benefit this has over someone keeping Facebook inside a separate profile in Chrome. If Mozilla's trying to attract people from Chrome... I feel like they need to be a bit clearer on what precisely Mozilla provides that Chrome doesn't?

I use Firefox on Mac, but I don't notice any performance hits. At least not compared to Chrome, or browsers on other operating systems. I don't use Safari so maybe I don't know what I'm missing out on. What performance issues specifically do you notice?

The two main things I notice: Some websites basically crash the computer on Firefox but run fine on Safari. Mostly JS heavy sites. The energy usage of Firefox is way higher than Safari, which in turns makes my fans spin a lot harder. Basically some sites will peg the CPU and hit max fan speed, but the same site just sips energy on Safari. Video streaming is a prime example of this. I can use twitch on Safari and it u…

> Video streaming is a prime example of this. I can use twitch on Safari and it uses maybe 30% CPU. Twitch on Firefox uses 150% CPU.

I concur - Firefox consistently uses higher CPU than Safari in my experience too. "Idle page" CPU when nothing is apparently happening but it's draining the battery anyway is higher with Firefox and annoying.

With the exception of LinkedIn, oddly.

Safari uses 105% CPU consistently when a LinkedIn tab is in the foreground.

I use Firefox multi-account containers[1] extensively, it's honestly the primary reason I use Firefox these days. The big win for me is that I _hate_ having to use the Google account switcher, so I basically set up a container for each Gmail account (work, personal, old email, etc). The nice bonus feature is you can have certain sites default to containers. I had a paid YouTube account for a while, for example, so ha…

Would you be willing to share your config? Last I checked, I'd have to enumerate every Google domain and subdomain, which just seemed like too much work. But if others have already done this, itd be easy to just use theirs.

You can use this. It's a fork of Facebook Container, but for Google.

This one is a fork for Amazon https://github.com/krober/contain-amazon https://addons.mozilla.org/en-US/firefox/addon/contain-amazo...

There's a few more too

I use multi-account containers and temporary containers so that all my new tabs are isolated. Is there any reason to also use facebook container if you already have multi-account containers?

> I use multi-account containers and temporary containers so that all my new tabs are isolated Worth mentioning that with the addon cookie auto-delete, you can more or less emulate temporary containers.

Temporary containers has a plethora of settings for when to open a new container. For example, I have a rule enabled that will open links in a new temporary container when they leave the current one. That's a terrible explanation, so let me give an example to make it clear:

- I have a GitHub container

- github.com and gist.github.com are set to always open in the GitHub container

- Say I am currently browsing github.com in the GitHub container.

- If I click a link to a domain other than [gist.]github.com, instead of navigating my current tab to that url, the url will open in a new tab & new temporary container

This is more powerful than simply persisting cookies from github.com -- I'm keeping GitHub's cookies, but only in the github container. It's almost like first party isolation, but a little weaker (unless you enable the setting where any link to a different domain will open in a new container), and I have the ability to group sites that would break with 1st party isolation by opening them in the same container.

I'm confused. Containers work by URL. How do you use a different container per Google account?

The Facebook Container extension is special, it does a bunch of work to put all of Facebook and only Facebook inside the Facebook Container. Bits of Facebook trying to peak through outside Facebook (e.g. tracking pixels) are elided entirely. Which is exactly what I want. But ordinarily that's not the behaviour you get from a Firefox container.

e.g. I have that Facebook Container, and I also have a Slack container I just put together in the usual way by opening my Slack session (it's for the main social group I hang out with, during the pandemic) inside a Container with a pink theme and icon.

Suppose three friends send me a funny Youtube video of kittens, one sends it on Slack, one on Facebook, one literally sends me a postcard with the URL on it.

In Facebook, it's inside the Facebook container. Since the Facebook Container has no idea who I am, Youtube presents adverts and of course there's no way to add the video to my "Fun kitten videos" list. But if I tell Youtube to open this now the tab is not Facebook, a no-referrer link opens with the URL and now in my default context which has Youtube Premium, so there are no adverts and I can add this to my lists. As far as Facebook is concerned I apparently just left. Unless Google tells them I watched that video they are none the wiser.

Slack is inside the Slack container. So again, no Youtube account, adverts. But if I open the Youtube page that's still inside the Slack container, so still no Youtube account. I need to explicitly get the URL and paste it into a not Slack tab to get my default context.

The link from the postcard obviously I get to choose which context to type it into the URL bar, although maybe the UX of typing random Youtube URLs in isn't great.

"Delete no longer needed temporary containers 15 minutes after the last tab in it closes" is a default setting. This is not an issue I've experienced in the 3+ months I've been using this extension. Are you sure you didn't accidentally change it?

I can confirm what others are saying, using temporary containers with the default settings left me with hundreds of containers to clean up.

I don't remember what the default settings are, but I do remember changing a fair number of them (and they are numerous). Definitely not the most friendly tool to casual use. But when fully configured, it is my second favorite addon (behind uMatrix).

Everything freezes, I can't use move the mouse. If I wait, sometimes I can hit Cmd-W and get the tab to close eventually, sometimes I literally have to do a hard power off.

I haven't experienced this on my 2020 macbook nor my 2012 macbook. Care to link an example of some heavy javascript?

I don't keep track of which sites do it, and it's fairly infrequent, but if I happen across an example I'll let you know.

Is it possible to have each domain open in a persistent container? It looks like Temporary Containers uses a new one each time a site is visited. Containerise, on the other hand, seems to need to know about each domain in advance.

I use persistent containers based on domain. Works brilliantly.

With what addon?
