Fedora27: Firefox freezes

[Terry Barnaby]

Is anyone else seeing issues with Firefox freezing up for 30secs or more 
when web pages are opened in TABS ?

Since the latest Firefox 57 this is happening a lot for me (every 10 
mins or so). Seems to lockup while downloading the page. You can still 
operate Firefox by clicking on menu's/Tab's etc, but no tab windows have 
thier web content updated. Normally the new tabs content are blank, but 
sometimes a small amount of the web page is rendered before the freeze. 
No obvious high CPU usage when it happens. Its as if the network has 
stopped, but other applications such as google-chrome are still working.

This is with Fedora27, KDE Plasma and with an NFS mounted home directory.

I see something similar with FF57 on Centos-7. it tends to go on for
much longer than 30 seconds, and the HD activity light is pegged ON
for the duration. I'm guessing it may be a swap storm, but I don't see
unusually  high memory usage in top.

I had problems with Firefox freezes (very long delays responding to any
mouse
click) on several systems (linux and macOS).  Removing the Mr. Robot add-on
(https://www.engadget.com/2017/12/16/firefox-mr-robot-extension/) seems
to have restored normal operation.

Well, in my case it is also often longer than 30 secs, not sure how long 
as I normally go and do something else while its loading the pages. I 
don't think it is disk related, no obvious activity (SSD disk and 16 G 
of RAM). No addons and reset all Firefox settings etc. Internet access 
here is 80/20 Mbps FTTP and seems solid so I don't think it is Internet 
connection related.

But the problem does seems to be network access related, maybe multiple 
thread locking issues in Firefox ?

I don't think it is that one. The display is fine all other applications 
run fine. Its just that the Firefox tab does not load any content for a 
while. I can still operate Firefox clicking on things etc, but no tab 
will update its contents.

Have you tried the Firefox Help Site?  This may not be Linux related, 
and it doesn't hurt to ask.

Will do so, just trying to find out if it is well known on 
Fedora/KDE/Plasma or if it could be a one off due to something in my 
setup/config somewhere.

FWIW, I do not use FF extensively.  It is configured to use a proxy and I only use it
to access US based media sites.  When I do use it I've not noticed any problems.

You mention your home directory is NFS mounted.  You may want to consider moving and
creating a symbolic link to ~/.cache/mozilla to local storage.

Hi I tried symbolically linking ~/.cache/mozilla to local storage. This had no effect.

I have also seen some strange freezing on a separate F27 server. The SDDM login GUI was frozen. A ssh to the system would freeze. a web access to port 80 would timeout. NFS was still working, although the remote systems had NFS server UP/Down messages in the logs. Accessing a Mariadb MySql server on the system was fine though. A hard reset was needed. Very strange ...

[Stephen Perkins]

I had the same problem with FF 57 on Fedora 26; found solution on FF forum:

go to about:config
and set accessibility.force_disabled = 1 (it's 0 by default)

worked for me.

I did see this one mentioned for MS Windows systems and tried it just in 
case, but it did not seem to have any effect in may case.

MY FF had not frozen or stopped, but it had gotten slow.  making this

As recommended did change the apparent speed of loading pages.  Thanks.
