The following kern.log is a record of the kernel events. Please note
that I used the widget to close the Ethernet connection, and note
subsequent issues. Also note that the WiFi connection has a lease time
for a nailed up connection IP address (??)

Title:
Firefox: all tabs loose page display and internet access but new tabs
work normally
Status in gnome-nettool package in Ubuntu:

Bug description:
Significant problems with KUBUNTU 16.04.3 WiFi.
I had been an early adopter of KUBUNTU 16.04, before the warnings
about on-line upgrade from KUBUNTU 14.04 came out. To solve those
problems, I re-installed KUBUNTU 16.04.3 from disk over the system
partition of my PC while retaining my user partition, applications,
and downloads partitions (also WIN10) KUBUNTU 16.04 WiFi was bad
before and remained bad after. KUBUNTU 14.04 had some problems, but
that eventually was resolved.
Most recent complaint is Firefox will loose all displayed tabbed web
pages and those web pages cannot be refreshed. Opening a new web tab
works perfectly. Pasting a broken web page URL into a new tab works
perfectly.
For some time I have had WiFi failures on boot.The ifconfig initially
said there was no WiFi device. IMPORTANT NOTE: Ethernet has always
worked and I have had to string a cat5 cable across my house several
times to get network access for repairs. I installed network-manager
(it was missing ??) and WiFi showed up via ifconfig.
After installing network-manager (again) ifconfig showed WiFi with a
new ID: wlp12s0. Next I manually inserted this new ID into
/etc/network/interfaces because wlan0 is apparently OBE:
#--- wlp12s0 ---wlan------
auto wlp12s0
iface wlp12s0 inet static
address 192.168.99.12
netmask 255.255.255.0
gateway 192.168.99.1
wpa-ssid Disco
wpa-psk pre-shared-key
At this point, WiFi would work about 50% of the time on boot/reboot.
ifconfig always shows it as configured. The network-manager widget
only shows it when it is configured via boot-up. If boot-up fails to
configure WiFi the widget only shows Ethernet. It is displayed in
network-manager but it is not available to connect. Network-manager
showed Ethernet as available to turn OFF. Eventually I tried to put
Ethernet up/down in as an option and eliminated Ethernet always up
(this was explicitly not set to be always up, but that was the case
anyhow) Now Ethernet up/down is always up on boot-up.
BEGIN DIGRESSION
When I looked at the password, I noted that in network-manager there is a
wallet requirement to access the password (if I chose to use it) so I tried
that. That accomplished requiring me to unlock the wallet on the occasions when
WiFi was working. However WiFi did operate more often the before. I made the
password available without wallet since it did no useful help in this problem.
This improve operations even more, but not reliably at all times,
END OF DIGRESSION
I next installed WiFiRadar which sometimes would run and other times
would not.(It remains installed but I am not using it now. In
particular, it could not raise WiFi from the dead when it did execute
properly. It did allow me to correct some elements of the WiFi
configuration that network-manager had wrong. It fixed the password
issue.
An odd part of this problem still occurs when WiFi does work (now
about 80% of the time): ifupdown enp9s0 is connected as UP when WiFi
is also UP on boot-up. In this situation Ethernet interferes with
network access as if it is a valid connection to the same router as
WiFi. When I disconnect ifupdown enp9s0, it remains available for
connect but WiFi no longer is interfered with by the Ethernet
connection that was not there. When I run ifconfig enp9s0 down,
ifconfig no longer shows enp9s0 but the widget still shows ifupdown
enp9s0 available to connect.
The Firefox issue appears to not be related to that application
directly.
I have a broadcom WiFi device in a Dell 1525 Inspiron laptop.
