No.
Some time ago there was a bug in Lightning that resembles your problem:
https://bugzilla.mozilla.org/show_bug.cgi?id=827078
And, it was pushed to 1.9.1, but it's never appeared in the "official"
releases.
I was instructed to find it in the nightlies:

We did that, and we've had no problems with deletions, etc.

Should I install 1.9.1 found here?

I suppose I risk bugs using a nightly version but perhaps it's worth
it if it will fix the problem. I haven't heard that this version
actually addresses it but I suppose we'll see...
