That is a built-in Firefox container feature. Open a website in a container and then click on the container icon (right next to the search bar) to keep that site open in that container. Every other time, that site loads directly into that container
Yep, I think it's called "Containerise" with the British spelling. To make it work you need to remove your existing URL rules from the main container tabs add-on, or they'll fight like cat and dog if there's a conflict.
What's great about regex matching is that you can grab a regex for each of your Google accounts, and bookmark the URL that the regex matches. I've changed the Firefox search bar config to prioritise bookmarks in the results. I can now type 'gmail', and the top two results are:
Gmail (work)
Gmail (personal)
Each opens in opens in the correct container. The trick sometimes is finding a bookmarkable URL with a specific string that you can use in a regex.
To be honest it's one of the features I wish Firefox would add to their add-on because I don't like giving their party add-ons access to my data.
That was also the case for me (FF for Android), and I eventually found that I have WebGl disabled by default. Everything worked as expected after I resumed. FF animations run quite smoothly. Good work for developers.
Every galaxy we know of contains a massive black hole in the center. Until recently, the widely held belief was that massive black holes are formed via the process of mearging smaller black holes in large timeframes. However, once the JWST came online, astrophysicists discovered early massive black holes close to big bang that could not be explained by that cumulative process. There just was no time for the cumulative creation to a such large black holes.
So the current working hypothesis for massive black holes in galaxies is that they formed directly from the gravitational collapse of "vast clouds of gas and dust" with such high gravitational pressure that the core couldn't keep up, and the entire mass of gas and dust collapsed into a massive black hole. There is no supernova involvement; merely a direct transition into a black hole.
Of course, take my laic simplification into account.
A vast cloud of what gas and what dust? I thought we had started with only hydrogen and I thought that collapsing the hydrogen creates stars first. How could it even cut directly to the stage of black hole?
