I have often extolled the virtues of running Nightly and Beta versions of Firefox since it helps you to never be surprised about changes coming to Firefox, and to have a front row seat to providing feedback about new changes as they are still in development.
Another instance just happened today, and it is instructive, so here is a story:
u/202nine posted on r/firefox that browser.link.open_newwindow set to 1 stopped working as they expected. That was yesterday.
u/panoptigram then posted that it was removed/changed.
I then suggested that u/202nine could file a bug to report a regression, which they did: Links are opening new windows despite browser.link.open_newwindow being set to 1.
Today, the change was reverted. Regression and fix, all within a day or so.
If u/202nine hadn’t been running Nightlies and filed a bug, that removal may have stayed in place to release, where people would undoubtedly complained about feature removal.
If you are playing with advanced options, you owe it to yourself to run nightly, or at the very least, beta. Not doing so is saying that you don’t really care if the options go away.
