I'm running TVH 4.3-2375g653bd0400 on a Raspberry Pi Debian GNU/Linux 12 (bookworm) arm64.
I access the control site (port 9981) from various devices, but recently a Windows 10 PC running Firefox 134.0.2 is no longer able to open the dialog for DVR | Autorec, Add or DVR | Autorec, Edit: when I press those buttons, the browser window flashes slightly but nothing else happens. It used to work fine until a few days ago. All the other dialogs work OK - eg Upcoming Recording, Add.
MS Edge on the same PC works fine, and the same version of Firefox works fine on other PCs.
I've cleared all the history for all time {History, Cookies, Cache, Site Settings) from Firefox's cache, but it's not made any difference.
Has anyone else experienced this. I wonder if it's a recent update to Firefox which has done something odd.
Is there any tracing that I can run, so I post a log for people to look at?
