1604236 - Site-specific zoom behaves incorrectly after reset

Status: NEW

(Firefox :: Disability Access, defect)

Description

[Morgan Reschenberg [:morgan]]

STR (from :gijs)

1. open a tab A with example.com
2. open a new window B, also with example.com
3. in B, do a zoom reset (which is a no-op)
4. go back to A, and increment/decrement zoom

Expected: zoom updates in both A and B

Actual: zoom doesn't update in B, in which you did a zoom reset, because it ignored the next content pref notification.

(if you increment/decrement the zoom another time, it'll update correctly then)

I think this might have to do with this "hack": https://searchfox.org/mozilla-central/rev/c61720a7d0c094d772059f9d6a7844eb7619f107/browser/base/content/browser-fullZoom.js#157
