Something must have happened recently because this USED to work for me. I tried to login to my Dahua IPNVR but the LAN login site keeps throwing me the message about installing the Webplugin (which was already isntalled from when it was first setup). For some reason it now fails to recognise that it's already installed and won't let me log in. Just keeps prompting me to download and install it again. I've tried deleting the installation location folder and re-installing the plugin but the issue persists. This is on Firefox v49.0.2. I tried MS Edge but the site is so out of date/poorly programmed that it thinks its Chrome and redirects me to install the Chrome addon. A cursory look on Chrome's addon review page shows that everyone on there is having the exact same issue. At the moment I can still access my NVR via the mobile app as well as Dahua's custom desktop software. But i'd really like to be able to access it from machines that don't have the software installed. I don't have IE on my PC. Its 2016. Anyone got any ideas on how to bypass this?
