Since the newest version of Firefox (55.0.3) was installed I am receiving the following message when I run Malwarebytes Junkware Removal Tool:

Deleted the following from C:\Users\xxx\AppData\Roaming\Mozilla\Firefox\Profiles\k2f0l20a.default\prefs.js

user_pref(browser.urlbar.suggest.searches, false);

Should I be concerned about this? It's appearing in both of my computers

hi, that means you have disabled search suggestions in the url bar and that's obviously no need to be concerned. maybe that tool is just looking for search related modifications (since this is how many adware/malware programs work), but obviously that's a genuine one...
