# Browser requirements to use the Quortex I/O app

TL;DR: to get the best experience with the Quortex I/O app, please use a modern and up-to-date (6 months old maximum) desktop browser.

# Recommended configuration
Our customers have reported the best browsing experience with **Chrome**, **Firefox** and **Edge** desktop browsers, with auto updates enabled, and a screen width of 1280px minimum.


# Known issues
* Mobile / tablet browsers are not yet supported: we're working on a mobile friendly version of the app.
* Our customers have seen problems when using the "Private browsing mode" in Firefox. This is because some features of the app require IndexedDB, which is [not supported by Firefox in this case](https://bugzilla.mozilla.org/show_bug.cgi?id=781982).
* Our customers have reported problems with Safari versions older than 14.0.


If you run into a compatibility issue with your browser, don't hesitate to tell us about it using the chat icon directly in the app or using the links below this article!
