After a certain number Chromium based browsers stop showing the new tabs.

And usually stop working because they used up all the memory. I went back to Firefox after a week of using Chrome. Chrome is not compatible with my 100+ open tabs.

They're working on a profile switcher: https://connect.mozilla.org/t5/discussions/here-s-what-we-re...

Can’t you change the user profile in the command line with a flag? Surprised it takes this long to implement that in a gui fashion.

You can open different profiles by typing about:profiles into the address bar.

There's already a GUI (launch firefox with the --profileManager command line flag), but it's very barebone.

This flag and the UI seems to go back to (at least) Netscape 7 in 2002, btw.

And also about:profiles, with the same caveat.

The most important part of profiles is being able to right-click on a link and open it in a different profile. I don't see that mentioned. I typically have multiple profiles open at once.

Edge has the best implementation where you can define sites opening in certain profiles. Pity ms ruined that browser - it is completely untrustworthy with it auto turning on options such as syncing.

The lack of horizontal scrolling in Chrome and most chrome-based browsers drives me absolutely crazy, it's such a basic feature...

Firefox on the other hand has terrible support for profiles, I've been using Arc which is good but has worse performance when working with a lot of tabs (hundreds)

I can't take a browser seriously unless it's open source. Arc may be the best browser of them all in terms of features, but I'd never consider it as an alternative to anything until it opens up its source code. We shouldn't trust a closed-source browser.

Also on Firefox you can hold CTRL+T / CTRL+W to open / close multiple tabs, CTRL+Click or SHIFT+Click to select multiple tabs at once and then e.g. move them to another window or close them, etc.

I always assumed Chrome also had all of these features, including scrolling, etc.

I remember chrome has a flag for this.
