[webcompat-bot]

URL: https://addons.mozilla.org/en-US/firefox/themes/
Browser / Version: Firefox 55.0
Operating System: Linux
Problem type: Something else - I'll add details below

Steps to Reproduce

1. Navigate to: https://addons.mozilla.org/en-US/firefox/themes/
2. Try out one of the themes by hovering your mouse over it. Try out another one

Expected Behavior:
The browser switches themes and the site does not disappear

Actual Behavior:
The browser switches themes but the site itself disappears - goes full white. Hovering over the place where a theme was previously still triggers the browser to "try it on"

Thanks for the report. I can reproduce this issue. Certain themes like "Globules Multicolores" or "ABSTRACT'" cause the tab to go blank. As mentioned in the description, the page is still there and you can hover over different themes, but the page stays blank. Navigating away to a different tab doesn't fix the issue, only closing the tab does.

This isn't a web compatibility issue, but should be filed on bugzilla.
