Package: firefox-esr, firefox Version: 45.0.2esr-1, 45.0.2-1 Both firefox and firefox-esr can be installed at the same time, and when they are, we get 2 "Firefox" entries in the "Internet" apps menu, and even the tooltips are strictly identical. There should be a way to distinguish them.
It is especially causing problems today, where a handful of plugins did not gain the "|firefox" alternative dep and still pull firefox-esr through iceaweal, preventing those that would like to only have "firefox" installed to do so.
