Details

I tried to close some tabs, and the browser hung. I clicked the main close button, and after a little while Firefox closed and I saw an Unresponsive Script Error, Script: chrome://browser/content/tabbrowser.xml:2153.

Version 37.0.2, stable, from main Mozilla download site, running on Debian Jessie with Cinnamon desktop environment.

(There are lots of possible duplicates, but they all have different line numbers on them.)
The different line numbers are because the line number varies per version and OS. Could you post the source code corresponding to that line number? (see instructions in bug 1041788 comment 7.) We don't have an easy way to see what source code that line # corresponds to in your version of Firefox.

OK, here's suitable looking chunk of the file, with line 2153 itself being `if (!aTab || !aTab._endRemoveArgs)`:

      <method name="_endRemoveTab">
        <parameter name="aTab"/>
        <body>
          <![CDATA[
            if (!aTab || !aTab._endRemoveArgs)
              return;

            var [aCloseWindow, aNewTab] = aTab._endRemoveArgs;
            aTab._endRemoveArgs = null;

            if (this._windowIsClosing) {
              aCloseWindow = false;
              aNewTab = false;
            }

So I think this is a near-exact duplicate of https://bugzilla.mozilla.org/show_bug.cgi?id=1151403, and they seem to be being collected in https://bugzilla.mozilla.org/show_bug.cgi?id=1078280
