Bookmarks sidebar not working properly.

I keep my Bookmarks Sidebar open. It works properly for a few minutes and then it doesn't. The behavior it shows is as follows.

1. It quits scrolling. I have to click the web page and go back to the sidebar to scroll again. 2. It scrambles the bookmarks when I click one. 3. When I click one bookmark it opens some other one.

Basically it acts crazy. The one fix I have found is when it is acting up and I close and reopen the sidebar it starts working properly again for a while. Then the problems repeats until I close and reopen the sidebar.

Chosen solution

Start Firefox in Safe Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration or userChrome.css is causing the problem.

  • switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Themes
  • do NOT click the "Refresh Firefox" button on the Safe Mode start window

I was using the LIGHT theme. I went to the DEFAULT theme and my Bookmarks Sidebar is working normally. Thanks a million.
