Details

I've encountered a situation where tab restore on startup loses lightning tabs. Not using lightning long and I don't normally do lots in tabs, so I don't know if this is tabs issue, a restore, a core issue or calendar.

1. install calendar
2. install https://addons.mozilla.org/en-US/thunderbird/addon/clippings/ and force compatibility
3. open tabs for a folder, a message, add-ons, and calendar or tasks
4. restart
5. from am clippings problem you'll get "TypeError: Components.classes['clippings@mozdev.org/clippings;1'] is undefined"
6. click OK

actual results: calendar tabs are missing, other tabs are there

expected results: all tabs are restored
Does clippings provide a tab monitor or tab type implementation? I remember an issue I temporarily had with Lightning where an exception occurring in one of those methods caused more chaos even outside of Lightning.

unknown. 

I found a newer version 3.1.4 of clippings (about 1 month old - don't know why it hadn't updated) and it doesn't causes the error that version 3.1.2 does.

however, the issue remains that an add-on shouldn't cause pain for thunderbird tabs.
Does this needs to be moved to lightning ?
Looks to me more like this is an issue with the clippings addon, where Thunderbird could be more robust when it comes to checking for exceptions.

This is almost certainly no longer valid after Bug 1358906.  In fact, all of these "tabs/windows aren't restored" bugs should be closed unless provable in Tb55 or later.  Aside from compose window, which was never implemented.  See also Bug 1409457 comment 10.
