User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:47.0) Gecko/20100101 Firefox/47.0
Build ID: 20160604131506

Steps to reproduce:

- start Firefox (new installation, new user with empty $HOME, no addons)
- open several tabs
- repeat:
     - type something in the address bar (suggestion dropdown opens)
     - switch between tabs
     - maximize/un-maximize window

Firefox 47.0  Linux x86_64 (
Linux Mint 17.3 Rosa

Actual results:

The dropdown with the suggestions is not opened below the address bar, but somewhere else on the screen (random),
sometimes it covers the address bar, so I can't see what I'm typing in.
(see the attachment)

(The same misplacement problem was observed in other input fields too, e.g. when entering saved user name + password)

Expected results:

The dropdown is opened below the input field.

Is it reproducible in previous versions of Firefox like 46 or 45?

I found that I do not experience this bug until I focus on an input field, at which point this bug will remain until I recreate the tab. The suggestions for forum input are also misplaced once this bug begins.

Mozilla Firefox 47.0

To reproduce:
- Open Firefox
- Type in address bar
- Move window
- Type in address bar again
- Open a new tab
- Now all suggestions for all tabs will be displayed in the same area as step 2

Are you working with 2 displays?
If yes, it could be a recent regression.

Can you install the tool mozregression (see for details) and run the command "mozregression --good=44" then copy here the final pushlog to narrow down a regression range.

You should use a config file. Please use the --write-config command line flag to help you create one.

Was this nightly build good, bad, or broken? (type 'good', 'bad', 'skip', 'retry' or 'exit' and press Enter): bad

So the first regression I tested had the same issue, should I go back further?

I do have two displays, however this bug still appears when I have only one monitor enabled.

It seems to be a Gtk3 bug, since FF46 (1st support of Gtk3).

Thanks.  I think this is the same issue as bug 1022241. says that Mint 17.3 has GTK+ 3.10.8.  I don't know whether this is limited to only some GTK versions, but it seems that some are seeing this bug while others are not.
