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?

Hi,

After updating Firefox, you can try deleting all existing instances of Firefox and its related files in all the different configuration areas/modules of Norton 360. Instead create new allow/trusted rules for Firefox + its related processes. Even otherwise the Norton 360 may also ask again when Firefox is started and you can try to allow/trust at that time. Please see this.

AV/Firewalls Configuration

Once Norton 360 has been configured you can consider the Reset Firefox feature via Help (Alt + H) > Troubleshooting Information to start afresh.

(To revert to the previous profile you were using, close the new profile, start Firefox and choose the Default User profile. While the Profile Manager is open, you can also delete the newly reset profile (the one containing random numbers), or the former profile, as the case may be).
