THe Browser crashed when attempted to open a new tab at Verizon site. Now Both my Beta and reg Firefox are showing the infamous pop-up message already running ..need to close it first etc. .But no apps running no processes running, no parent lock found just found in properties unable to permanently remove/change from read only but nothing indicating corrupted files!! Included the last crash file folder marked 'pending' , Please tell me why this great browser has this recurring problem - I already had to create a new profile twice now and this time haven't migrated old files yet as the old profiles were supposed to work again after I changed their properties from read only ! this is very frustrating and stressful while doing online job searches . . and I now don't trust browser enough to utilize different browser profiles as a tool for college, or other !!
