Hi I'm fairly new to the dev area and I've been trying to find a solution to this issue but haven't found one yet, so I hope this hasn't already been asked before. Problem: When opening the pop-out character sheet in Firefox, the window appears but the content is completely missing (except for the individual subheadings of the sheet). Refreshing the pop-out makes the window completely blank. This is what it looks like: When I click 'edit', it opens the character sheet as normal within the original page, and edits there. Clearing the cache does not seem to help. Reproduction: I actually am not exactly sure how this happened in the first place. The first time this issue occurred, my internet was on cap so it was loading everything very slowly. It would load the character sheet the first time, but then it timed out (this was several weeks ago). Since then, even when my internet is back to normal, as it is now, the above issue still persists. I am not sure if this is a browser compatibility issue, or I've messed up some sort of cookie or saved option within Firefox. No matter if I log out of the dev roll20, or jump out of the campaign, or refresh the campaign page, it does not solve the issue. When I the campaign in Chrome (version 39.0.2171.99 m), this issue no longer happens. Setup: Firefox 35.0, Windows 8 64 bit, wired internet, using the dev roll20. Javascript and Cookies are enabled, Flash: 16.0.-1 (not sure if these make any difference).
