Searching ScrapeBox Navigator Equivalent for FF or Chrome

Hey all
All is said in the title of the thread.
I need to visit large amount of sites for selection. The SB navigator is nice but slow - I need something like an addon for FF or Chrome.
Function should be:
-navigate through URL in CSV or TXT file
-delete url from the file
-add url if needed
-auto save
-support big listing (5k - 10k)
-maybe also should load a lighter version of the site, but the site need to be understandable and easy to evaluate

Do you know something?
I know Flem for FF - nice addon but buggy and not very well finalized.

Thanks in advance.:crazy:

Have you checked out iMacros? It's pretty flexible and can read (and I believe write) files.

Adgate - thanks for your suggestion. Already thought about iMacros but I dont know to script, to be honnest I'm laz...searching for a ready made solution.
