The modal popup shown in comment 3 is shown using the magic Firefox-only `@-moz-document()` CSS, to make it specifically appear for Firefox, regardless of user agent: ```css #unsupportedbrowser, #hideunsupported { display:none; } [...] /* Firefox Browser Styles */ @-moz-document url-prefix() { #unsupportedbrowser { display:block !important; } } ``` This would work to override that, as an intervention for https://m.pge.com/ : ```css #unsupportedbrowser { display: none !important } ```
