Mozilla has kept the current about:config page in Firefox that was built on XML aside (still available by default in release) and created a new about config page by using HTML and default styles from Photon design system. The new page can be accessed and seen in Nightly.
The about:config has been converted into new, information is the same but the display is different and usage also changes. For instance, in old page, double-clicking an entry changes preference the value, in the new page, doing so selects the text. You need to use triple-click to select the preference name or value. The company is planning to keep old about:config page around for some more time at chrome://global/content/config.xul.
Performance: On slower machines, you may notice the page a bit slow to load all preferences for the first time on screen and the developers taken care so that the navigation, scrolling and find in page will be fast anyway once the search results are displayed.
If you’re curious to see the Firefox’s new about:config page, follow the steps below
1. Ensure you’re using latest Firefox Nightly
3. Click ‘I accept the risk’ to new “Here be dragons warning ” which shows the same message as in the old page, but offers new checkbox ‘Annoy me again, please’
4. Search for something you’re looking for by typing in filter or press Esc to display all preferences and their values
Note: Cursor should be in the search field for Esc to work. Here is the old or current page of about:config.
