Comment 27 for bug 281348

theLured: if you read the prior entries in the bug report carefully, you'll see that a bunch of people have reported that just disabling "Ubuntu Firefox Modification" is sufficient to prevent the problem, regardless of twiddling localstore.rdf. i'm following up just so people aren't mislead by your entry to believe there's any need for (or, if i'm understanding Myk Dowling's response correctly, any benefit from) removing localstore.rdf.
