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 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/
    <https://www.engadget.com/2017/12/16/firefox-mr-robot-extension/>)
    seems
    to have restored normal operation.

        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.

    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 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.
