My OS is Win7 with Norton 360. I recently downgraded from FF 14 to FF 11 because I would always get a "Content Encoding Error" message whenever I would to try to access the "News" button from my Google home page. I've set my browser preferences to "English", "never use instant results" and "show 50 results per page". None of these settings ever get saved. My browser always launches in Spanish with instant results and 10 results per page. Furthermore, I still get the "Content Encoding Error" message when accessing "news" from Google. I've cleared my cache, run the antispyware to remove tracking cookies, run Norton to remove malware, deleted my prefs.js file and restarted my laptop. Nothing works. Apparently, this is a recurring problem with FF. Why hasn't it been fixed by Mozilla?

You can check the network.http.* prefs on the about:config page and reset all bold user set network.http prefs to the default value via the right-click context menu -> Reset.

Check at least:

  • network.http.accept-encoding (default: gzip,deflate)
