Thx for very fast reaction, new version works fine. I have another small improvement. Sometimes we must open add-on in window (when have many tabs open), but another time better is open in tab (when have less tabs open).So my proposal is:

Add to the add-on icons action for middle-click mouse, when we press middle we run add-on contrary to the options of the setup. So when we have in options "open in tab" and click middle mouse, then we open in window, when click left mouse we open in tab (as in options).

A small change but it can be very convenient.

Edit: And in about protocol we see old position about:cacheviewer2, I think you can delete it.

This review is for a previous version of the add-on (1.1.1-signed.1-signed).  This user has a previous review of this add-on.

i add a button to switch tab or window mode in version 1.3.and about:cacheviwer2 is still needed, so can't delete,i just rename it from old version.thank you for your advice
