I used Ctrl-R to reload a page I was on but it triggered a reload in multiple other open tabs. When I go to each open tab and click the "x" to kill the reload, it starts up again shortly afterward. If I close and reopen a tab it still stays stuck in an eternal reload loop. In fact, in both cases, the little clock icon does not disappear from the tabs, which seems to indicate that the reload is never actually killed but just paused. Restarting FF does not end this behaviour even though my tabs are supposed to reload only when clicked on. Even a few tabs that appear to have completed the reload process continue to display the little clock icon and ultimately start reloading after a brief pause. Meanwhile, FF is nearly useless as it eternally tries to reload all of the tabs.

Suggestions are welcome.
