Foxmarks unknown error occurred (411)
Foxmarks is the first extension I install every time I setup Firefox.I never have to worry about loosing my bookmarks anymore and now my passwords too! Recently it’s being acting up with a “unknown error occurred (411)“Â error during setup. The workaround fortunately is quite simple. Go to Tools -> Foxmarks -> Foxmarks Settings -> Advanced Change encryption to “Encrypt All”. That’s it.
