The Payroll Site

Why don't you support the other versions of Firefox?

We only officially support a browser once we have checked every feature of every page in that version of that browser. This is to ensure that our customers do not encounter unexpected problems when they use the site.

Mozilla release a version of Firefox every six weeks and they stop supporting most versions six weeks later. This short lifetime makes it impractical to apply our high standards of testing.

Every seventh version of Firefox is designated an Extended Support Release (ESR) and is supported by Mozilla for about 12 months. We support these versions of Firefox.

Although we don't officially support the non-ESR versions of Firefox, we know of no reason why they shouldn't work and are happy for you to use them. If you do come across a browser-specific problem on our site, we will recommend you switch to using a supported browser.
