                <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>
