Firefox continually stops responding when I click on a bookmark. I get the info at the top of my screen that Firefox is not responding. Now if I go to MS office and am working in Word with Firefox in the background, word freezes. I go to Task Manager, it says Firefox not responding. End task and office works. Even without office running, I still get the not responding problem. I use Windows 8.1 on a Dell desktop. This problem has been happening since Friday the 21st.

Problems with bookmarks and history not working properly can be caused by a corrupted places.sqlite database file.

You can check for problems with the places.sqlite database file in the Firefox profile folder.
