Im not sure when the issue first started as Firefox updates quite often. Here is the issue: When logging into my router settings page locally,(http://xxx.xxx.xxx.xxx to access router on network), the forms constantly overlap. For example there is a form on the left that shows each settings page and the form on the right which is the settings i currently have selected. When each settings form is loaded it is overlapped by the form on the right. To fix it i zoom in or out. And the forms re-align. But then they almost immediately snap back making it almost impossible to enter any data. This has not been an issue in the past, but i havent had to adjust my router setting for a while. It's driving me insane, so much that i installed a chrome browser just to access my router info. But i would prefer to use firefox as i do not like chrome. This is also on both an old install and a brand new install of windows 10 and new install of firefox. The router is a c4000bg from centurylink. Thank you for any assistance in the matter.
