The obvious solution, using SeaMonkey, has not worked for me - it lacks too many extensions. I use KeePass to hold my passwords in a secure place and I wouldn't want to have them stored in a browser ever again. A decent replacement for the combination of FlashGot and DownThemAll!, pretty much allowing me to download any media from any website with support for parallel downloads, pausing them, etc.Something like Firebug which allows me to modify a website's CSS on-the-fly.

I use to have a plenty of them open at the same time and I like to keep an eye of them. Tabs on the left side of the browser window.It would be awesome to have that in the new browser too. In Firefox I have 'open all in new tabs'. For example, I open certain links once a day. Pocket doesn't work for me, I need real folders. I've been using Xmarks since it was called Foxmarks, but I could live with moving my bookmarks to a different online service as long as it's in some way integrated in my browser. Bookmarks with online backup/synchronisation.

A decent JavaScript blocker, such as µMatrix or (at least) NoScript.

An RSS icon in the address bar so I can see if the particular page has an RSS feed available.

'The browser' should be able to give me most of the following functionality (the more, the better) right from the core or with extensions: I have a couple of 'requirements', features I learned to love and I wouldn't want to miss.

Mozilla is not interested in having me as a user and extension developer anymore, so I'll happily leave if any browser can replace Firefox well enough. So, basically, that's the last straw for me. DTA!'s author had already said that he will stop further development when Firefox gets rid of XUL support which will be 'soon' anyway. Having been a rather proud user for quite a while (I even wrote some popular Firefox extension), I don't quite like the direction Mozilla is taking, including the oversimplified Australis UI and some other weird decisions however, the latest beta 43.0 made DownThemAll! 3.0 (beta), one of the last extensions which stuck me to Firefox, not work anymore due to some signing issues. I've been using Mozilla Firefox since its humble beginnings as Phoenix (from the ashes of the Mozilla Suite).
