In Firefox, the content in the Preferences pop-up box disappears when I scroll down. If I click and highlight, it comes back.
I have also been encountering this in Firefox. I noticed it a few weeks ago, but don’t know how long it has been happening. I initially thought I had to click something for the content to return, but discovered that if I just wait several seconds the content will reappear on its own. Still, it is disconcerting …
Is anybody experiencing this not on Firefox? Seems like a FF rendering bug that they need to fix.
On Iceweasel 10.0.7 (Firefox 10.0.7 essentially, but from Debian) and on Chromium 21.0.1180.89, it doesn’t happen. But on Firefox 15.0.1 on Windows 7 I also experience this.
I’m going to chalk this one up to Firefox. They’ll fix it eventually. Not much I can do, unfortunately.
Just downloaded FF 16, and the Preferences screen no longer disappears.
