I've been using firefox for years... Firefox is cool. Slack huddle in my Firefox never works, I don't know why. But that's cool. If someone in the team needs a "huddle" I can give a reason and ask them to describe their problem instead. That works 99% and saves me a lot of time.
whatsapp requires to access to contacts on the phopne. otherwise it just shows a bunch of phone numbers and I never get who I'm talking to in the groups. And it shares my phone number to everyone.
Such a feature hasn't been changed and now I know why
In my team when someone asks me to look at some issues, my very first question is always where they see the alert. Because there are a huge number of "alert" channels. And I am very "happy" spending most of my days doing nothing much than searching and looking up things lolz
In the spacing section, the author's suggestion to use absolute spacing operator (e.g \;) is actually not recommended. a better way is to make `dx` a math operator (`d` is an operator isn't it?).
Some other suggestion is not actually recommended in the official documentation of amsmath as I recall.
I love firefox.
