I just lost a longish reply on a discussion forum (vBulletin v. 3.8.5) using Iron 25.0.1400.0 for Windows (7). I pressed the Quote button, wrote my reply, then searched for one link to add, didn't find it, did something else meanwhile leaving the browser page open for about an hour or a half, searched again for the link to add, gave up and pressed the Preview-button to see if I made any typos. The browser showed me the prewiev for a second, then flashed and gave me a completely white page. When I pressed the Back button I saw some flashing for a second or two, and then my reply was gone, only the original quotes remaining.
And amateur mistake, I know (trusting a computer to hold your data in it's memory). But is there anything anyone (including myself) could do to make this browser more usable for us silly humans?
