Whenever I am using Fire Fox after about 20-30 minutes the menus (even the main menu icon), function pop-ups (e.g. click on the print icon to get the print pop-up asking number of copies, click on a download icon to get the pop-up asking destination), etc. stop working. This happens all the time independent of what site(s)/tab(s) I have open at the time. Tabs still work (a new tab will open). Sometimes I am actively using Fire Fox at the time, other times it is open but not my active window (in this scenario when I return to make it the active window again I find that the problem has occurred). Once in a while it will try to open something that generates an error message (NS_ERROR_FAILURE):
JS frame … contentCache … js::ObjLayerActionGoToNewWindow::line 7 data:no
In this case it was trying to open a survey window at the end of a course I had just completed. Most of the time I don't see an error message - just an audible ding and nothing happens.
When this problem occurs I have to completely restart Fire Fox to clear the problem - for another 20 minutes.
I've tried clearing the browsing history, turning off hardware acceleration, making sure pop-ups are enabled, and installing the latest version of Fire Fox (63.0.1). I'm not sure what else to try.
My laptop is Windows 10. According to Fire Fox these are the installed plug ins:
