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.

    Oh you like add-ons, we HEAR you. That's why we're changing the API again for the 3rd time and requiring registration of authors and the signing of a pledge to support the Mozilla Foundation. This will temporarily make all existing add-ons incompatible while the add-on authors finish jumping thru hoops and doing busy-work. Congratulations on choosing Firefox!

    PS. We know you're going to enjoy our new feature "Browser Theme U Love And Can't Disable" that we just hardcoded in for you, brought to you by our partners iWillBreakYourWillAndSellYourDataMuthaFucker.
