I have longstanding problem with Firefox which I cannot eliminate & none of suggestions I got from Mozilla Support worked. Certain operations caused Firefox to crash, but no crash reports are created & I do not receive a Crash notification. One example is that when I receive an email that contains something I need to print like labels or tickets, Firefox crashes when I try to print & if continue to try to print, it always crashes. Here is an example of a return label. https://www.wayfair.com/session/secure/account/print_labels.php?label_id=11186731&Or=2953552973&Svc=&csn_id=A691DFAE-672C-4481-9D3B-EB2D17913431 Another example is downloading. If I try to download, Firefox crashes, again with no crash report or notification to me. Many times when I try again it works the second time. But sometimes it doesnt. Firefox just closes without a trace. Then I have to do restore last session. As I said, with some operations, it works if I do it again, but with others it does not. I looked at Windows Event Viewer & the application log. It has many evens for each day & a total of 17,703. I found one from a couple of days ago that mentions Firefox & another one that mentions Software Protection & lists a number of items with a long list of letters & numbers that look like Firefox crash reports When I use Chrome, I dont have these problems. So I have made Chrome my default browser although I prefer Firefox if these problems can be fixed. Thank you. Jonathan Rose
