Firefox resetting theme upon opening everytime.
Firefox is resetting theme upon opening every time. Splash page keep going to white, even though dark them is enabled. Have to go disable, then re-enable.
Note: Some software, like Advanced SystemCare with Surfing Protection, can protect files in the Firefox profile folder against changes. If you have such software then check the settings or uninstall this software.
Macs: Make sure you install Firefox properly and that you do not run Firefox from within the DMG (Disk Images) file. https://support.mozilla.org/en-US/kb/how-download-and-install-firefox-mac
