Frequently Asked Questions
Which browsers do you test against?
We test against Pale Moon, Waterfox, SeaMonkey, older Firefox/Chrome versions, and other niche or legacy browsers that mainstream CI tools ignore.
What does a compatibility report include?
Each report includes full-page screenshots, JavaScript console errors, layout diff highlights, and a pass/fail summary per browser.
Can I test pages behind a login?
Yes. You can supply session cookies or basic-auth credentials when submitting a URL so we can reach authenticated pages.
