Your webpage [https://support.mozilla.org/en-US/kb/firefox-repeatedly-opens-empty-tabs-or-windows] accurately describes the problem, but the solutions offered don't fit. I don't want to start a new session (I keep a great deal in tabs) and this isn't a problem with crash or unexpected close. It has nothing to do with content type. It has nothing to do with unwanted content. The pages are blank. I'm writing because I have a particular website I want to visit and Firefox refuses it open it. I click on a link. I get a blank page. I copy the link to a new tab. I get a blank page. I shut down and restart Firefox I get a blank page. I rebooted the computer, I get a blank page. Sometimes it helps to press extra firmly on mouse buttons. Not today. Sometimes it helps to copy the link and use Paste and Go, not today. At least this time the reload button is clickable -- not that clicking it does anything. There are times when the reload button is grayed out. There are times when the destination URL doesn't even show up in the URL bar. This problem has been going on for many months, perhaps more than a year. Usually the work arounds work. Not today. I get it that a problem is hard to fix if the software developers can't make it happen. I used to be a programmer. So I would be glad to try to help developers fix this problem.
