There are around 500 crashes a day with DTToolbarFF.dll

These are representative stack signatures, and firefox versions where the crashes are occuring.   there is more info about the breakdown in https://bugzilla.mozilla.org/show_bug.cgi?id=459850#c36 but we can keep the discussion about these new crashes here.

DTToolbarFF.dll@0x4bc19 Firefox 3.0.10

DTToolbarFF.dll@0x4bc19 Firefox 3.5.2

DTToolbarFF.dll@0x39b70 Firefox 3.0.13
DTToolbarFF.dll@0x3d52d Firefox 3.0.13

out of a sample of 100 dttoolbar crashes I see a few signatures and a few dttoolbar versions.  these crashes stretch across just about all firefox 3.0.x and 3.5.x versions.

  80 DTToolbarFF.dll@0x4bc19
   2 DTToolbarFF.dll@0x52b13

  16 DTToolbarFF.dll@0x6087e

Summary: DTToolbarFF.dll@0x4bc19 and related crashes on version → [@DTToolbarFF.dll@0x4bc19] and related crashes on version
will check this version of the toolbar this week
I have an email contact with the dttoolbar guys, so please contact me for the email address before blocklisting them.
not able to reproduce so far ...any ideas how to get steps to reproduce ?

ss:  Can you please add the dttoolbar contact info to bug 523883 ?
Done, as a private comment.
This isn't showing up in the 3.5.3 topcrash list anymore, so suggesting that it shouldn't block release.

It's #44 on the topcrash list. What list are you looking at that it doesn't show?
Flags: blocking-firefox3.6- → blocking-firefox3.6?
Huh, my search on that page failed. Yes, topcrash #44 blocks.

Needs an owner. According to the Crashkill wiki page that's Tomcat.

yup will try again :)
Carsten, do you have the v1.0.8.522 of the toolbar?  The oldest version on AMO is Could you send it to me if possible? Thanks.

Henrik, seems i recycled this vm with this installer already :(, so don't have this toolbar version anymore, hopefully we can get it from our contacts mentioned in #11
so, since this is a old version and the new version is version 1.10 maybe we should with our contacts if we should blocklist this old version ? Damon do we got a answer from this vendor ?

Whats the next step with this one?  

Damon: any word from the vendor? (comment #11).  Let me know if I can help contact them.  We could really use an old copy of their tool bar from them (see comment# 14). Can just block list them (comment #16)

Tomcat or whimboo:  Any luck finding the right version of toolbar ourselves?

no, all download links i found so far are now pointing to the latest version :(
Older versions of the Daemon Tools are available here:

No idea if this software also included the toolbar. But given by that side all versions >4.0 include badware. So we should try those builds.
I don't believe that this should block release, though we should follow up with the vendor and consider blocking the older (crashy) versions of the DLL.

Current statistics are showing strong correlations to specific versions of the DTToolbar:

DTToolbarFF.dll@0x4bc19|EXCEPTION_ACCESS_VIOLATION (191 crashes)
    100% (191/191) vs.   1% (652/99896)

DTToolbarFF.dll@0x568b9|EXCEPTION_ACCESS_VIOLATION (71 crashes) 
    100% (71/71) vs.   0% (332/99896)

DTToolbarFF.dll@0x6087e|EXCEPTION_ACCESS_VIOLATION (51 crashes)
    100% (51/51) vs.   0% (210/99896)

DTToolbarFF.dll@0x570a9|EXCEPTION_ACCESS_VIOLATION (18 crashes) 
    100% (18/18) vs.   0% (102/99896)
Thank you Henrik, but we already know this is correlated to DTToolbar and is crashing there. We've dealt with a similar crash before.

We also don't need to use the DLL blocklist. We can blocklist this with the regular add-ons blocklist, which is what we've done before.

Damon, have you heard back from the DTToolbar guys?

It's probably more important to investigate which versions are crashing and if the new one is or not. It's possible it's still crashing and the signature has changed because it's a new DLL.

That doesn't necessarily answer the first part of my statement, which is that we need to breakdown the module versions that are crashing to determine if the new version is crashing. It might be crashing in a different way, but while we have contact with them, we can get them to fix those crashes.

Dear Samta,

I think it answers the most important parts of key question which is:

...is DDToolbar.ddl release (actually having an impact in reducing the high volume of crashes in previous versions?  

The answer to that is yes.  The bottom of comment 28 also shows a list of possibly new crashes low volume crashes that could be looked at now or some time in the future to figure out if there are *any* new problems with the new version.

Please bring me a new present for the holidays to do what you are asking for.  It sounds like a new, fun, and exciting tool.   give crash-stats, or crash_analysis a .dll and version number and have it say which signatures apply.

The only way to do this is go by hand as in:

the new crash with
search for the signature
   4 DTToolbarFF.dll@0x535f3 1202

look at a report
see the version number
which is not the new version..
rinse and repeat for all reports on all signatures...

I also ran a 
awk '$0 ~ /^  [A-z]/ ||  $0 ~ /1\.1\.1\.0014/'  20091203*versions*.txt   | more over all of the Firefox data in

"DDToolbar.ddl" shows up in being around in a few crashes by not visable to any high degree, or correlated with any specific signature. 

lets let this one rest until the new .dll has a chance for wider deployment, then have another look.

I'll leave you cookies and milk, and carrots for the reindeer, and bring me the tool if you can.  I've been a good boy this year. 

love, chofmann

Looked at 1800 crashes where the signature has DTToolbarFF, here are the versions:

    595	DTToolbarFF.dll|
    559	DTToolbarFF.dll|
    476	DTToolbarFF.dll|
    135	DTToolbarFF.dll|
     30	DTToolbarFF.dll|
      3	DTToolbarFF.dll|
      1	DTToolbarFF.dll|
Thank you Cheng. That's exactly the information I wanted.
Let's blocklist the older versions, then; looks like the latest ( version is having the happy effect we were hoping for.

Also, not blocking release on this, but should keep it on the crashkill radar.
