Nextcloud version (eg, 12.0.2): 15.0.10
Operating system and version (eg, Ubuntu 17.04): Debian Strech 9
Apache or nginx version (eg, Apache 2.4.25): Apache 2.4
PHP version (eg, 7.1): 7.0
After an upgrade from 15.0.8 to 15.0.10 the apps page is blank and white under Firefox. Using Chrome everything is shown correctly and as expected. I have to servers with a similar setup, problem occurs on both.
