I've experienced several problems recently, following a Kaspersky Anti-virus update to version 16.0.0.614(e) . Apparently after the my dial-up internet connection drops, Firefox freezes, and freezes everything else. Before the connection drops everything runs fine for several hours. If I get control back - i.e. if the browser finally closes - it wants to send a report to Microsoft - even though I wasn't running I.E. I guess its a Windows thing. I haven't been prompted by FF to send a crash report in all this time, but crash it has. Per a FF help, I checked about:crashes and nothing is listed since January, before all this bizarre stuff started happening. I sent the report to Microsoft since they asked. This is what was in it. C:\DOCUME~1\Amy\LOCALS~1\Temp\WER2151.dir00\firefox.exe.mdmp C:\DOCUME~1\Amy\LOCALS~1\Temp\WER2151.dir00\appcompat.txt szAppName: firefox.exe szAppVer: 44025884 szModName: hungapp szModVer: 0.0.0.0 offset:00000000 If I don't get control back from the hanging FF, and choose to force a restart, I notice error messages before shut down. The latest were -.net-broadcast followed by A.case no.3 .... I have no idea what these mean. I also had an event 2 days ago with a hot link in an email booting IE while FF was running. That had never happened before. target of hotlink: https://weather.com/weather/today/l/Bloomfield+NJ+07003 where it ended up: window titled: Address not valid - Windows Internet Explorer and the url: res://ieframe.dll/syntax.htm# I hope someone can shed some light on these experiences. Thanks
