Hover tool tips not showing data in Firefox

Community Support

Hi yes I am indeed facing the exact same problem as you!!! I have not tried other web-browsers though but I use Firefox on my Ubuntu 14.04 running as a VM on my host Macbook. I’ve been getting question marks when the Hover thing pops up on my own code, as well as the periodic table example, and also this tutorial http://bokeh.pydata.org/en/latest/tutorial/solutions/gallery/hover.html
Anyone else facing this issue? What’s the problem here?

Anyone else not seeing hover tool tips display correctly in Firefox? It appears there is an issue with propagating the hover tool tips with data when using Firefox browser. My plots with hover tool tips display correctly in IE and Chrome, but not Firefox. Also, the example periodic table (http://bokeh.pydata.org/en/latest/docs/gallery/periodic.html) behaves similarly where only question marks (???) appear in the data fields of the hover tool tip.

The problem appears to be with FF, and upgrading to a newer version seems to fix the problem:

If that is not the case, please leave comments on that issue.

Thanks,
