Hover drama hits hard
Fixing my tooltip accessibility mistake
Firefox dev admits tooltip blunder as commenters split between praise and pure rage
TLDR: A Firefox developer admitted they fixed a tooltip the wrong way, accidentally making a button less understandable for screen-reader users. Readers split between praising the clear, honest walkthrough and blasting the whole method as overcomplicated, turning a small design mistake into a surprisingly heated accessibility debate.
A Firefox web developer publicly confessed to messing up a tiny pop-up label, and the internet did what it does best: turned a humble correction into a mini comment-section soap opera. The original post is basically a cautionary tale about making buttons understandable for people who use screen readers, software that reads websites aloud. The author thought they had fixed a repeated word problem, shipped the demo, and headed off happily—only to get a polite but very real tap on the shoulder from accessibility experts saying, actually, the button had lost its proper name. Oof.
The comments, though? That’s where the real fireworks are. One camp loved the way the mistake was explained, with ChiperSoft cheering the step-by-step code changes: the “diff lines” made it easy to follow. It’s the kind of nerdy compliment that lands like a standing ovation in web-dev land. Then came the hard left turn: mort96 slammed the whole approach with a blunt “This is horrible”, basically declaring they’d rather ignore the new pattern entirely and stick with an older shortcut.
That split says everything. Some readers were into the honesty, the teachable moment, and the rare sight of a tech person saying “I messed up, learn from me.” Others reacted like they’d just watched someone overcomplicate a light switch. The accidental comedy is delicious too: a three-minute explainer about a little hover box somehow became a full-on debate over what counts as “good enough” for disabled users. Tiny tooltip, huge feelings.
Key Points
- •The article documents an accessibility mistake made while implementing a tooltip for an icon-only toolbar button in a demo about `popover="hint"`.
- •The author adapted a tooltip pattern from Scott O'Hara that uses `aria-describedby` to associate a button with descriptive tooltip content.
- •In the icon-button example, using both `aria-label` and tooltip text caused VoiceOver to announce the word "Bold" twice.
- •The author removed `aria-label` to avoid duplicate speech output, but this left the button without an accessible name.
- •Feedback from Léonie Watson and Gez Lemon of TetraLogical clarified that `aria-describedby` adds description and does not replace an accessible name.
