Is this a feature request or a bug?

What is the current behavior?

A command like this ends in an error:

web-ext --verbose run \
  -t chromium \
  --chromium-binary /Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome \
  -t chromium \
  --chromium-binary /Applications/Brave\ Browser.app/Contents/MacOS/Brave\ Browser

...

What is the expected or desired behavior?

This command should launch both Chrome and Brave and support auto-reloading in both.

Version information (for bug reports)

• Firefox version: n/a
• Your OS and version: n/a
• Paste the output of these commands:

node --version && npm --version && web-ext --version
v10.15.3
6.11.3
master-e315c932777b09ed992003f384ec90abe649a0d6 (near the 3.2.0 release)

The log has this in it:

[extension-runners/chromium.js][debug] Starting Chromium instance...
[extension-runners/chromium.js][debug] (chromiumBinary: /Applications/Google Chrome.app/Contents/MacOS/Google Chrome,/Applications/Brave Browser.app/Contents/MacOS/Brave Browser)

...so maybe the launching part won't be too hard.

Also see #1269 for running multiple versions of Firefox.

We could support this (at the CLI) by supporting multiple --chromium-binary (and also --firefox-binary flags). It could be by using an "array" type. but we should be careful to not repeat the same mistake as--start-url and its friends (#1707), i.e. the flag should take exactly one argument, and any repetitions need an explicit flag before the value.

take a look on this tool https://github.com/kimmobrunfeldt/concurrently.

I think it's going quite over the scope of the web-ext. Really, try concurrently (or split terminals, as a resort).
