#1 25 security fixes?

1.0 users should upgrade immediatley as 1.0 is plagued with security holes. And that's just what the internal developers found, add to that what the evil hard core hackers could find and OUCH! I tremble just thinking about it.

look at the list - if you would list everything like this for MSIE, it would have around 500 security problems

#3 Stability vs 1.1?

by saidiadude

Wednesday September 11th, 2002 12:34 PM

Local city college is interested in rebuilding some old machines (PII 200MHz or so, Win98SE, OpenOffice/StarOffice). Are there are reliability measures for Moz 1.0.1 vs 1.1? Will be used for browsing and email mainly. If the "experiment" goes well, we may be able to spread the good word within the admin (using TCO, etc :-)

#5 Talkback Info?

by Kommet

I suppose the Talkback info from the 1.0.1 and 1.1 builds would tell you which was more stable and to what degree. The Talkback reports tell total uptime (usage time) for Mozilla, total number of launches, total number of abnormal closings (crashes), and so forth. I suspect that only once 1.0.1 has been out for a while and received some Talkback data will we be able to say how stable it is.

This info from Talkback is only available to Mozilla-hackers ? Or is it publicly available somewhere ?

#20 Crash data

by Salsaman

Friday September 13th, 2002 3:47 AM

Crash data is here:

MTBF (mean time between failures) for 1.0 Branch is ~9 hrs, and for seamonkey (1.1/1.2a) it is ~6hrs. (Assuming I am looking at the right data). Of course for general use, your own MTBF should be much longer (since installations which crash more quickly obviously send more crash data).

From this, it appears that the 1.0 branch is more stable than 1.1; however YMMV.

Is this available on-line in graph form? Need to show pics to non-techie bosses who don't know what "ftp" is :-) Would be great to just send the URL to a mailing list.

Mozilla 1.1 has a nasty habit of crashing if you close a window with an animated GIF ( Stick with 1.0.1 for now.

#26 resource intensity with Mozilla 1.1b

by smkatz

Sunday September 15th, 2002 9:03 PM

Due to resource problems with Mozilla 1.1b, you should stick with stable releases for now, hence the name. I am running Windows ME. Problems should be severely reduced for NT-based and Unix-based OSes. BTW, they are quickly resolving the quick launch issues which I am happy about.

#4 CPU at 100% for Moz 1.0.1?

by saidiadude

Wednesday September 11th, 2002 1:58 PM

Just installed Moz 1.0.1 on laptop - Win98SE AMD 233MHz, 128MB, 4GB HD. Noticed that CPU is pegged at 100% permanently when Moz is running. Any ideas? First Moz install on this machine. Moz 1.0 or 1.1 did not do exhibit such behavior on other machines.

Hm, turn off HTTP pipelining? That was a notorious issue for awhile.

It is not checked (i.e. off by default). What is "Enable Keep-Alive"? This is checked ON by default.

#21 Fix: Uncheck "Enable Keep-Alive"

by saidiadude

Friday September 13th, 2002 11:19 AM

Unchecked "Enable Keep-Alive" and the CPU util drops (it did not seem to work at first, but a subsequent reboot fixed the problem). Prior to this, CPU util would be pegged somewhere between 80%-100%, now its at a more normal 10%-20% most of the time.

#8 Automatic upgrade utility???

by maxie3

Wednesday September 11th, 2002 9:41 PM

I love mozilla 1.0 and I want to upgrade to 1.0.1. I would think that there would be plenty of people in my same situation.

Are we supposed to backup all of our data files, uninstall mozilla 1.0, install mozilla 1.0.1 and then copy our files back???

If so, is there some automatic utility that does this to reduce errors and/or to encourage the less techie people to upgrade?!?

At the very least, maybe the steps to upgrade should be explicitly added to the Release Notes.

yes, exactly. With all the releases it would seem an auto-upgrading system is needed.

With pre-1 releases it was ok, b/c I didn't use them long. Now I've used 1 for a long time, have tons of passwords and bookmarks saved. Bookmarks you can copy easily, but I think last time I tried to copy my passwords it didn't work, so I'm wary of upgrading.

-Or a "live update" as with Norton or something. That would be really good.

Maybe a short-term easy fix might be to add some sort of backup/restore the File dropdown. You'd get a popup with some checkboxes allowing you to specify what you do or don't want to backup and to where. And then, the restore would just do the opposite.

But basically, just anything to make the upgrading easier for us lesser-techs.

You don't have to backup your profile. The uninstall will not touch your profile. Just uninsall the old mozilla and install the new mozilla. It's that simple.

#12 RC2 vs. final?

by chrishickman

Thursday September 12th, 2002 1:03 AM

What's the difference? I haven't been able to find any kind of changelog showing this, only one showing what's in 1.0.1 final.

you could do a bonsai query to check exactly what changed, but I think answer is that virtually nothing changed except the version number - although there's been a delay in releasing it, the 1.0.1 builds are from 26th August, just a couple of days after RC2.

#23 DOWNgrading from 1.1 to 1.0.1?

by saidiadude

Friday September 13th, 2002 11:26 AM

Is it possible to downgrade from Moz 1.1 to 1.0.1? What is the process? Simple uninstall of 1.1, then install of 1.0.1? Need to preserve mail, addr book, bookmarks.
