Hi,
I used Opera and FF before, now I moved to FF because it is a secure and convenient. Having said that I wasn't able to find three useful features:
<b>Fast forward/backward</b>. Allows to go to the next/previous page. Very useful with forums.
<b>Minimize tab</b>. Allows to minimize (rather than close) a tab (not window). If someone posts 'quantum computers employ entanglement', I would open a wiki tab, read the first paragraph about entanglement to get an idea what it is, and go back to his post. However, I want to read the full wiki article after I finish reading the post. Minimize tab would be the best solution.
<b>Open in a background tab/window</b>. Opens a page in a background. Someone posts 'gravity spreads with a light speed (link)'. I want to read the paper after I finish reading the post. Then I open the link in a background tab.
Are there any extensions that address these questions?
Thanks
