Rated 1 out of 5 stars

unimpressed with the functionality of this add on. I still encountered many 404 Page error on pages.
frustrating when something that says it does and doesn't. This add on was part of my computer crashing.
Up to you to decide.

This review is for a previous version of the add-on (1.2.1).

interesting... i didn't receive a complaint from anyone else, and there were more than 60,000 downloads. maybe something else was crashing your computer...

also in regards to 'I still encountered many 404 Page error on pages. frustrating when something that says it does and doesn't.', you obviously didn't read description and when exceptions occur if you were expecting it to find every missing page...

UPDATE: i now see that in Firefox3.0 on GNU Linux, 'whitelist' option doesn't work if permission of 'whitelist.txt' file is not set properly -- just change permission and it will work.
