Summary
Usage
Key shortcuts:
- Shift+Alt+X: De-widthify current page (and un-stick fixed page elements)
- Shift+Alt+A: Disable all styles (CSS) on current page
To "undo" any changes made to a page: refresh the page. No changes are permanent.
De-widthify Many websites restrict the width of their text columns. Some people find this unergonomic, especially on small laptop screens and/or articles that require lots of scrolling.
This addon subverts the most common way websites implement fixed-width text columns: margins in CSS. When you press Shift+Alt+X all page margins are nullified.
This solution is not 100% reliable. Some websites will work fine, others may look ugly or break. It's impossible to make a page-modifying solution that works on every possible site out there.
