Works in Ubuntu 18.04 LTS but not in 19.04. I installed the "chrome-gnome-shell" native host connector but upon trying to install it tells me that the download is corrupt. Please update this pronto for Firefox, as I do not want to have to use Chrome/Chromium to get extensions!

Sadly, this fails to work for me on Ubuntu 18.04.2 LTS.

After installing chrome-gnome-shell 10-1 via apt-get, this extension indicates that it cannot find the native host connector on extensions.gnome.org under Firefox Quantum 66.0.3, stating "Although GNOME Shell integration extension is running, native host connector is not detected. Refer documentation for instructions about installing connector."

The sister extension ( https://chrome.google.com/webstore/detail/gnome-shell-integration/gphhapmejobijbbhgpjhcjognlahblep?hl=en also version 10.1) works fine under the official Chromium build 73.0.3683.86.

Both browsers were installed using Ubuntu Software Center.

Happy to change rating if this can be resolved.

Per chi usa Gnome è indispensabile. E' il modo più per gestire utili estensioni dal nostro browser preferito.

This works. However, don't use it if you install a similar one for Chrome/Chromium, and you enable synchronization of GNOME extensions in Chrome/Chromium (as per https://www.omgubuntu.co.uk/2017/04/sync-gnome-shell-extensions-google-chrome). When I used both, then GNOME integration for Firefox uninstalled GNOME extensions that I had installed in Chrome.

OK
