I also confirm this problem in my system, even with all extensions disabled. It has been happening for more than a month.

Status in firefox package in Ubuntu: Confirmed Bug description: 1) Ubuntu 18.04.1 LTS x86_64 with GNOME 3.28.3. 2) Firefox: Installed: 64.0+build3-0ubuntu0.18.04.1 3) Dialog box 'open as' to respond to click events in elements and whole browser not get inoperable. 4) Dialog box 'open as' hangs, gets inoperable to click commands (close, cancel, ok, save file) when trying to open some attacked file. My browser started to hang when the dialog 'open as' appears. It's very useful since it quickly opens an attached file from gmail or browsing pdf/doc files. When the dialog opens, both the dialog and the browser window get extremely slow and i have to click several times for the dialog to close. No other button responds and sometimes the crash dialog asks if i want to force quit or wait. I'm having this problem for two weeks now and got so annoyed that sadly had to switch back to chrome. This is a very nice feature that doesn't work on said browser. I already uninstalled/installed, cleaned data and installed a nightly build without success. I suspect it's something related to window manager or nautilus.
