I no longer use external Screen capturing software for my web browsers anymore. I use addons when best possible.

I am an Opera and Firefox user.

For Opera 20 I currently use Nimbus Screen Capture; https://addons.opera.com/en-gb/extensions/details/nimbus-screen-capture/?display=en

I have tested other Screen capture addons on Opera 15+ (blink) and so far Nimbus Screen Capture is the best and has the best developer support.

For Firefox (I know not relevant here) on firefox I use both; https://addons.mozilla.org/en-US/firefox/addon/screengrab-fix-version/ AND https://addons.mozilla.org/En-us/firefox/addon/screenshoter-fixed/

Just offering my two cents (or shall I say pennies)

I am myself using Opera 20 with some nice addons, especially 'Easy Tab Manager' addon and the 'Classic Images' and 'Classic Tabs' addon. I also use the 'Tab Hamster' addon for sessions saving. These addons I have aforementioned, recreate much of that Opera 12 (Presto) experience for me but there are still limitations in the extensions API as to how far extensions developers can customize Opera.

That's the difference between Opera extensions and Firefox extensions (addons). The Firefox offers it's extensions developers Two models, one model is like sandbox and the other model is native and offers nearly total control of the Firefox browser and system it's running on. Whereas opera extensions (as they currently are) are more like userscripts and follow that sandbox model.

For me, I was one of the many users that ranted and raved about lack of Opera native features found in Opera 15+ (compared to Opera 12). I never had any complaints about the transition to the Blink chromium engine because I think Opera did a good thing moving to Blink.

I just wish that the Oera team would listen to it's users instead of being silent and retreating away like a defeated army general! I wish these forums had active Opera team developers that would LISTEN to us instead of users having to resort to writing up these non complacent topics.
