Firefox freezes when I try to attach files larger than 700kbytes to my email which is fastmail. Have downloaded a new Firefox and created a new profile.
This is a problem which has been occurring for some time. I have tried various fixes eg clearing cookies, refreshing Firefox. My last attempt was to uninstall Firefox, install a new version and create a new profile. It has not worked, again Firefox froze up when I tried to attach a 2 mbyte file. I get no problem when I work through Internet Explorer which indicates to me it's a Firefox problem not a Fastmail problem. I am really disappointed as previously I used Firefox for a number of years without problem and I have grown used to it.
