Firefox 27 breaks images – DON’T RESET FIREFOX!

Seriously, don’t reset your Firefox solve this problem.

That’s what I did, and it took me down a rat-hole of re-installation that I did not have to pursue.

I had the unwelcome experience today of opening up pages within Firefox only to find that the images were not rendering. Some would, but more would not.  One tell-tale image was Facebook’s logo.  Just gone.

Images were sometimes gone completely, sometimes shown with a broken image icon, or some times with the image’s alt-image text.

Usually when I have a problem with Firefox, it is the result of a bad-acting plug in. In this case though, I had not installed any new plug-ins and was surprised to find this disruption of my browsing experience.

The first troubleshooting step, as usual, is to restart Firefox in safe mode. In safe mode, Firefox ignores all of your browser plug-ins, extensions, and all the whatnots if you’ve used to tune your Firefox browser.  But this time, it didn’t work. The images were still broken. Now, I was totally flummoxed.

So what to do?

This is what not to do: reset Firefox. Although it will work, and images will return, it is only a temporary solution illusory, and takes you down the long rat-hole of reinstalling all of your plug-ins, tweaking the application, correcting the position of toolbars, and putting the icons that you use back to their correct places.  I did this only to find that the broken image problem was not actually corrected by the reset.

To fix Firefox and bring images back to where they should be, open a new tab and type into the browsers location bar about:config.

Firefox will throw up its usual warning of disclaiming all responsibility for you breaking the product, before you head this is the path to salvation.

The next step is to type into the search bar of the about config page following terms: permissions.default.image

Firefox will quickly bring up the Preference permissions.default.images. The setting for this should be a “1”.   Any other setting, like “2”, will make your images break. I found the Value of this preference to be changed by Firefox updating to version 27.  This happened on two different machines on the same day.  By right clicking on permissions.default.images preference and selecting “Reset,” Firefox resets the image permission and all is restored!

I hope this saves  you the hour+ I spent resetting Firefox and reinstalling plugins etc.!
