Chat and Poll options not working in Firefox and Firefox-related browsers

[Moin]

There is another report about polls not working in Safari here

Voting in polls sometimes doesn’t work for a user

We have some users who cannot see the vote buttons in polls, they just see this: [IMG_1327] Not sure what Safari browser version they are using but I will ask. Is this a known issue? Also it may be related but I sometimes see that and then after a refresh it is fixed, but they say it’s not working.

It is about the same forum.
Have you tried to reproduce on try.discourse.org?
