And the crash: https://crash-stats.mozilla.com/report/index/bp-daac6321-dfe9-4e90-902b-3920a2111220 Note that the browser can hobble along sometimes...it seems to happen when the toolbar puts up a sheet at the start. I also didn't get the crash on Aurora (and then using the same profile it didn't crash on Fx9). So, to be safe, let's block this for Fx9+ on all products and if we need to dial it back later we can

(In reply to Christian Legnitto [:LegNeato] from comment #0) > Extension versions to block: All > Applications, versions, and platforms affected affected: Firefox >= 9 That would give them no possibility at all to get out of the block, ever. We should only block up to the highest add-on version that is out and contact them so they can fix a future version. Also, did we test if other platforms than Mac have the same problem?

I revise my earlier position...I think we should block only for Firefox 9 (all versions of the add-on though). I'd hate for them to release an update that didn't fix the issue and cause a bunch of startup crashes overnight. We can later restrict the version if they fix or workaround in the Fx9 timeframe. Also note the total ADUs are pretty immaterial (< 100k)

I think this would be the first time we block with no upper bound of version - at least for non-malware. We should give them a clear way out with a fix and upgrade. I'm not saying we shouldn't block the add-on, I'm just trying to not make us destroy the chance of working positively out of this with that company.

I had a brief conversation with them a few weeks ago. I sent them an email telling them to chime in here so that they know what needs to be fixed.

I believe Christian is suggesting that we remove working versions from the blocklist in the future if they fix their add-on, in which case they would no longer be blocked. Jorge - is that possible? If not, we could create a maximum version on the blocklist entry that's a little out of reach in case they release without resolving.

One other question - is it possible to blocklist on a per-platform basis?

Yes, it's possible to blocklist per-platform. I briefly blocked this in production about an hour ago and removed it when Marcia indicated that this is reproducible from several popular add-ons. I'm holding off until QA knows more.

Alright, this has been blocked in production for Firefox 9 only. Kev, please let us know the version number of the fixed version when they give it to us.

Look Guys I am not happy about this, Nectar Toolbar has never crashed on my PC, I WANT IT UNBLOCKED OR I WILL BE LEAVING FIREFOX

(In reply to Gavin from comment #12) > Look Guys I am not happy about this, Nectar Toolbar has never crashed on my > PC, I WANT IT UNBLOCKED OR I WILL BE LEAVING FIREFOX Gavin, please update to Firefox 9.0.1. Nectar Toolbar is compatible with that version. If you're still finding that the toolbar is blocked on Firefox 9.0.1, we may need to tweak something on our end.

Do you want it reduced to only 9.0a1 - 9.0?

(In reply to Justin Scott [:fligtar] from comment #14) > It's blocked in all of Firefox 9. Do you want it reduced to only 9.0a1 - 9.0? I went ahead and reduced it from 9.* to 9.0.
