Mozilla Firefox may reset custom browser preferences when the web browser is updated to a newer version so that the preference is set to its default value.

I was contacted by two Ghacks readers in the past two weeks about Firefox resetting preferences of the web browser during updates.

Jern informed me that Firefox reset the block lists setting of the browser's Tracking Protection feature from strict to basic when the browser was updated to version 50 from Firefox 49.0.2.

Basic protection is the recommended and default value of the setting. It does not block as many trackers as the strict blocking list. I confirmed that the upgrade to Firefox 50 did indeed reset the preference.

Michel told me a week later that a recent Firefox update (to 50.0.1 or 50.0.2) did reset another preference. This time an URL string that Michel modified on Firefox's about:config page.

    These days I’m waiting for it to crash and burn so it can be reborn again.

      You omitted Mozilla (the suite), which was a complete rewrite of Netscape. So it's

      Mosaic → Netscape → Mozilla → Firefox → ???

      Although the first succession isn't exactly like the others because Netscape was not based on Mosaic, but was an independent development. Indeed, the direct descendant of Mosaic was Internet Explorer.

        Yeah, it should rise like a thunderbird or phoenix out of the ashes...
