Hi, Recently I noticed this issue: 1. I start Firefox. 2. I click on a bookmark which is on the bookmark toolbar. 3. The page seems to initiate navigation to that bookmark, but eventually stays (it never navigates). 4. I click again on the same bookmark. 5. Then, Firefox navigates to it. I tried disabling Addons and disabling Hardware Acceleration, but it didn't help to fix the issue. This was suggested in this archived thread: https://support.mozilla.org/en-US/questions/1245362 A similar issue happens when I'm already in GMail website and then click on another bookmark, but it refreshes the GMail instead of navigating to the other bookmark. (I hope to reproduce it soon and tell you the results.) Using Ubuntu 18.04.
