Question [Q] Can't download internet files after updating firmware

OK, I have a rooted and unlocked Sprint HTC One. I recently updated the firmware to the latest version and ever since I can not download files from web sites (mp3s, zip files, etc. etc.). I click on the link and the download always fails. I've tried multiple ROMs, different browsers, fixing permissions, etc and nothing seems to work. I can load apps from the Play store fine, just no internet files. Has anyone seen this before? Is there an easy fix? Thanks for your time.
