Bingo. DownThemAll is something I would describe as "mission-critical". I had trouble getting two different versions of Firefox to not interfere with one another in odd ways such as everything running fine until I open a file with Firefox as the associated program and one version would open but have all the settings from the other version and Portable Firefox refusing to save settings or extensions at all. Using Chrome for casual browsing was just less of a headache.

This shouldn't be an issue if you run your secondary instance with -no-remote -profile="your separate profile".

That still doesn't answer the original question though. Why choose chrome over firefox, when it has no legacy firefox extensions? Does chrome have those legacy extensions' features built in? Was chrome better than firefox, and the only thing keeping you on was the legacy extensions?

Because they want an up to date browser for purposes that don't require the extension.

I run both Chrome and Legacy Firefox at the same time.

FWIW, DownloadThemAll works fine on current Firefox. I used it a few weeks back to grab a bunch of SNES roms from an open directory without issue. https://addons.mozilla.org/en-US/firefox/addon/downthemall/

Hey that's fantastic, thanks for the info. I'd given up hope.
