The Pale Moon Web Browser is a fork of Firefox and has it's own Extensions and Themes. It's available for Linux (also portable), Windows 7 - 10 (also portable) and Android. It also has it's own Browser Engine (Goanna) which is a fork of Gecko from Mozilla.
Use Search Plugins to search a lot of search engines, dictionaries (Leo) and communities for terms and definitions or images, from the integrated Search Bar.
If you use AdBlock Latitude I recommend to use the add-on with Peter Lowe's Adservers list and own custom filters, only. The EasyLists have tooo many whitelisted pages!
If you use uBlock Origin note that it's a general blocker, it blocks a bit more than only Ads. You can disable the EasyLists and use Peter Lowe's list with custom filters, too.

There are several language packs available.

Note about Firefox: From Version 57 (November 2017) a lot of the good old Add-ons won't survive!
