[Affected versions]: - Nightly 55.0a1 [Affected platforms]: - Windows 10, Ubuntu 16.04, Mac OS X 10.12 [Steps to reproduce]: 1. Launch Nightly with a new profile 2. Re-size the window - make it smaller 3. Focus the URL Bar 4. Open a new tab and start typing [Expected result]: - Step 3 - The search suggestions hint should be properly displayed as an animation - Step 4 - the URL drop-down and the hint should be properly displayed [Actual result]: - Step 3 - the hint does not fit the window - please see the screencast - Step 4 - the drop-down and the hint are not compacted enough to fit the windows size - please see the screencast

Adding to triage, imo not a P1, but let's see. Solving this and keeping the animation as expected may not be trivial. We could play with some media queries to change the expected outcome on small windows.

let's name this a P2, short term I plan to check if it's easily fixable through an additional css rule.

it was not easily fixable at all, took a bunch of hours, but this seems to be working good enough, even if so far I only tested it on Windows (in any case I'll test on Mac before landing)

I have reproduced this bug with nightly 55.0a1 (2017-05-29) on Ubuntu 16.04(64 Bit). While verifying this bug i can see an issue that the search suggestions hint is cut off a little from the top. Please check attached screen shot for clarification. Build ID : 20170605100313 User Agent : Mozilla/5.0 (X11; Linux x86_64; rv:55.0) Gecko/20100101 Firefox/55.0 [Bugday-20170607]

The fix works up to a certain acceptable width limit, we can't do better without sustaining development costs higher than the benefit and maintaining the required UX layout. Compared to before, now it should be possible to shrink the window a lot more, since the text wraps and the typing animation is removed. As I said, any further step from here may be expensive and won't still fit in a few pixels window...

Verified as fixed using the latest Nightly 55.0a1 (Build ID: 20170606030207) on Windows 7 x64, Ubuntu 16.04 x64 and Mac OS X 10.12. For the situations where the window's width is really small and the issue is still reproducible (see Comment 9), I logged bug 1370543.
