Weird question, but does anyone know of a simple tab viewer or organizer for Firefox (bonus points if it works on iOS)? I have... way too many tabs open, and I want to see what I can bookmark before closing rather than having to either close everything or manually check each tab.

Internet in my fiancee's house is weird. Once I open up a domain, going to links in the same domain is quite fast, but if I try opening another domain in another tab it is super slow. On Chrome it is really bad, Firefox is better but still sluggish. This occurs similarly on different devices running Windows, Linux, and Android. What could be causing this?
