FB Purity FBP newsfeed filtering is broken in Firefox 41 – How to fix it

Something has changed in Firefox 41+’s Javascript implementation that stops FB Purity’s newsfeed filtering functionality from working correctly in that browser. All other FBP functionality should still work OK in FF41 (and above). If you want to get FBP’s newsfeed filtering working properly again, there are a few different solutions available:

  1. Install the ESR (Extended Support Release) version of Firefox over the top of your current Firefox installation (during installation, if asked select the “Replace” option which replaces the current Firefox installation). This reverts Firefox to a slightly earlier stable version of Firefox (v38), that still receives all the latest Firefox security updates. FBP will work fine in this version of Firefox. Please note the installation process for Firefox ESR is quick and painless.
  2. Switch to using a different browser that FBP will run on, e.g Google Chrome (or chrome clone), Opera or Maxthon.
  3. *Update* I’ve managed to get the functionality that filters out the Ads (suggested/sponsored posts) from the newsfeed working again in FF41/FF42/FF43. Clear your browser cache then re-install the FF extension via FBPURUITY .COM for the fixed ad filtering, though all other newsfeed filtering functionality is still currently broken.

When I figure out a solution to the newsfeed filtering issue in FF41/FF42 itself, I will post a news update about it, so please be patient until then, if you are not prepared to follow my recommendations on fixing the issue yourself.
