I am legally blind and rely on a heavily customized, high-contrast Firefox interface to use the browser comfortably.
I have used Firefox with essentially the same visual layout and colour behavior for over 10 years, and I depend on that consistency to navigate the browser.
The Firefox 157 redesign changed much more than just the shape of the interface. The rounded tabs and buttons are one issue, but the bigger problem for me is that the colour treatment of selected and inactive tabs has also changed.
CHANGE IT BACK NOWWWWWWWWWWWW
Because of this, I can no longer clearly tell which tab I currently have selected.
For a sighted user, this may look like a cosmetic redesign. For me, it is an accessibility regression.
I rely on strong colour contrast and very distinct visual states to identify the active tab, browser controls, and different parts of the interface. Changing those colours and reducing the visual distinction between selected and unselected tabs makes Firefox significantly harder for me to use.
I am not asking Mozilla to remove the new design for everyone. I am asking you to let users choose.
Please provide a permanent, supported option such as Classic Firefox UI / Previous Firefox appearance that preserves the older layout, shapes, colour behavior, and selected-tab contrast.
Visually impaired users should not have to rely on about:config, unsupported preferences, extensions, or custom CSS just to restore an interface that was already accessible to them.
Major UI redesigns should not remove long-established visual cues without offering an opt-out, especially when those visual cues are being used for accessibility.
Firefox has always stood out because of customization and user control. Please preserve that by allowing users to keep the previous interface if the new one makes the browser harder for them to see or navigate.
You can use the new design. I just need the choice not to.
Please also do not remove the ability to disable the new interface in future updates.
