More info about the issue: if I revert the value of
browser.migration.version from 66 to 22 the problem with the tabs
reappears. Changing again from 22 to 66 make it go away but exhibits
a page saying that there was a problem restoring pages from last
session (bellow, in Portuguese):<br>

No errors on the console and the value was not a string. <br>

<div bgcolor="#FFFFFF"> Hi all!<br>
<br>
After upgrading from ESR 52.9 to ESR 60.8, some users
reported that only the first tab opened in Firefox was
working. They can open new tabs but cannot navigate on
them.<br>
<br>
I've found that the problem was with the property
"browser.migration.version" set in
"%appdata%\Mozilla\Firefox\Profiles\{userprofile}\prefs.js":<br>
<br>
user_pref("browser.migration.version", 22);<br>
<br>
Removing this line or setting the value to 66 fix the
issue. So, how exactly does this property works? I
couldn't find any information about this.<br>
