I’m having a problem with the “merge all windows” command. For example I have 38 windows open for a total of 91 tabs. I say “merge all windows”. And when I want to “bookmark all tabs”, apparently there are only 86 tabs open. I try it again and I have 87 tabs open**. So there are tabs disappearing, and the amount isn’t always the same.

[On a general note, I also have to say "merge all tabs" several times before ALL windows are as tabs in one single window. Probably this happens when there are lots of windows and tabs open, and this happens less frequently when there are fewer windows and tabs open?]

(** to avoid confusion, here’s what I do: I quit Safari while having 38 windows and 91 tabs open. I duplicate the lastsession.plist file. I open Safari again, “reopen all windows from last session”, and try merging the windows (and noticing that in the end some tabs have disappeared.) I quit safari again, I trash the lastsession.plist file, and rename the duplicate as ‘lastsession.plist’. I open Safari, say “reopen all windows from last session”, and when all windows are loaded, say “merge all windows”. Eventually again the tab number is lower than it should be, and different from my first try.)

So the problem is, certain tabs disappear, AND it’s not necessarily always the same windows and/or the same number of windows disappearing. I need to be able to trust this command so I do not lose tabs.

Any idea what might be going wrong here?

Thanks!
