Steps to reproduce:

Use the Zoom Text Only feature, and increase or decrease the zoom level.

Attachment: Bug 1378784 - Listen for TextZoomChange in addition to the FullZoomChange events to update the zoom UI when the zoom changes.

We were already listening for FullZoomChange. TextZoomChange is very similar, but is only triggered when the user has chosen 'Zoom Text Only' from the View > Zoom menu.

Jared, did you want to nominate this for Beta or let it ride the 56 train?

Approval Request Comment
[Feature/Bug causing the regression]: regressed by bug 1345375 in Firefox 55
[User impact if declined]: users who use Text Zoom won't see the zoom indicator in the URL bar
[Is this code covered by automated tests?]: no
[Has the fix been verified in Nightly?]: no
[Needs manual test from QE? If yes, steps to reproduce]: Change the zoom to Text Only (On Windows, Alt+V -> Zoom -> Zoom Text Only), then zoom in and out of the page (Ctrl+ and Ctrl-, respectively). The zoom indicator should appear in the location bar if the zoom value is anything other than 100%.
[List of other uplifts needed for the feature/fix]: none
[Is the change risky?]: no, just adds another listener for the TextZoomChange, we already were listening for FullZoomChange.
[Why is the change risky/not risky?]: see previous answer
[String changes made/needed]: none

Minor correction, the regressing bug was initially landed on 55 but was later uplifted to 54 so we have shipped this regression for one release already.

update, if this gets beta approval, then we should uplift the patches in bug 1383662 also.

I think I'll call this wontfix for 55, since we've shipped this bug already in 54, it doesn't seem critical, and it's late in the cycle with a single build left before RC.

I filed bug 1384522 to add an automated test.

I managed to reproduce this bug on an old version of Nightly from 2017-06-15 on Windows 10x64, macOS 10.12 and Ubuntu 16.04 x64.
I retested everything using the same platforms on beta 56.0b11 and latest Nightly 57.0a1 and the bug seems fixed.
