=== Add-on compatibility === | |||
* Did the Aurora add-on bump for Firefox 8 look for / track the changes in bug 455694? | |||
** No. Unfortunately I didn't know this was a compat-breaking bug back then. This would have been very difficult to detect through validation anyway. | |||
*** We're not sure what problems are caused by this. For example, akeybl was getting random UI lockups and it was an interaction between one of his tab add-ons and the new feature | |||
* Tab Mix plus is incompatible with the feature | |||
* Tree style tabs is possibly affected, 80,000 users in Fx 4 and later | |||
* Multiple tab is possibly affected, 75,000 users in Fx 4 and later | |||
** This should only affect add-ons that do major changes in the tabbed interface, or somehow manipulate drag and drop behavior for tabs. In the bug I mentioned Tab Mix Plus and Tree Style Tabs, and there are a probably a handful other add-ons that are affected. | |||
3. If so, can we get the ADU for #2? | |||
I also included some info in the bug. However, Tree Style Tabs isn't mainly distributed on AMO. I'll ask fligtar if he has some in-the-wild numbers for this add-on. I'll see if there's anything I can do to detect other affected add-ons, but like I said, it's hard to do. | |||
== | == Other considerations == | ||
== Impact of the backout == | |||
== | === Risk === | ||
* While it is always risky to change something that has over 12 weeks of testing, this backout doesn't seem too risky: | |||
** Fairly compartmentalized | |||
** Reverting to a known good state | |||
* Surveyed add-ons that adapted to the new code / APIs, only one Vertical Tabs had updated and it is created by a Mozilla employee who will change it back | |||
