New option Rated 5 out of 5 stars

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). 

fine

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

Select ALL Rated 5 out of 5 stars

Can you add option select all? Now when press Ctrl+A I get a save window. Now I see it dosn't mater what I click with Ctrl, every combination open save window.And option Show in tab not work, only show in separate window.

Edit: I know that select all its possible that way but as you see I must make unnecessary steps. Repair Ctrl+A or add select all button/radio/checkbox does not seem difficult, and will greatly facilitate the work (especially if I have a lot of elements).

This review is for a previous version of the add-on (1.0). 

you can select first then scroll to end and press shift select lastone, can select all.
show in tab has a problem, thank you feedback.
