I'm trying to open Chrome with trickle to throttle the upload speed so I can test a sites image uploading progress display, but the build in dev tools for chrome only allow throttling for downloads. This command works for Firefox, but Chrome's dev tools are just so far beyond what Firefox has to offer. Here's what I'm using now, which just leaves me with a blank terminal
trickle -s -d 256 -w 512 google-chrome-unstable
I've tried the stable version as well, but neither seem to be working.
