There’s Palemoon, which is not bad, but it is incompatible with many great addons.
So here’s my suggestion. Get Comodo Ice Dragon Browser, portable version preferably.
Get the add on Remove It Permanently [RIP]. You won’t need the bloated Adblock if you have this one.
Other addons that I use, listed in no particular order.
Tab Mix Plus.
X-notifier to check your emails. [And mail.com for hassle free, more or less, email provider].
Grab My Books, to turn web pages into epubs.
Ghostery. Maybe with RIP you don’t need this. Dunno.
Download Them All.
BlockSite Plus. Maybe with RIP you don’t need this. Dunno.
Flash Video Downloader.
Smart Video for Youtube.
Reddit Enhancement Suite.
Switch Private Browsing.
Twitter Disconnect. Maybe with Ghostery and/or RIP you don’t need this. Dunno.
Windows Programs I like:
Duplicate Cleaner Free
All are available as portable but for Chess Hero.
