Like others have mentioned, I wish I could turn off its automatic dead page detection. The reason is simple, it seems to be overly zealous and/or outright wrong in what it considers a dead page. If I come across a dead page, I'd rather manually go and click the icon in the addon bar in order to get a recent version.

I find it really, really annoying that I cannot block it's popup for some sites. For example, Reddit is down right now. Every time I reload, it pops its obnoxious "you wanna see an archived version of this page?" thing. No matter how many times I dismiss the damned thing. I don't want an archived version of Reddit. Please give us a way to black list sites from this popup!

A great addon but it sometimes thinks that a non 404 page is a 404 page, which is very annoying

The best.

It redirects many pages that are working just fine to the "Page not available screen", and there isn't a way to disable that part of the addon. I really like the ability to open a page in the wayback machine, but this addon gets in the way of my regular browsing too much.

The current version has an issue that it frequently consider a working web page as 404 and redirects it to addon page, especially when URL change or go back/forward, which is very annoying.

Very helpful extension, but it detects many working pages as 404, especially on browser reload. An option to disable automatic Wayback machine popup is really needed.

I love Archive.org, truly a priceless resource. Unfortunately the last few months I've been unable to use the "Save Page Now" function. It just goes to a blank page when I try. It seems like a problem through the core site, since when I actually go to Archive.org/*site and hit "save a copy" it doesn't work either.

I will consider changing the rating, once the major bug will be fixed, which causes this plugin to pop up on working websites.

(edited March 2022) The recent update is great. Being able to automatically archive all the pages I visit gives me a lot of peace of mind.

The bug of March 2019 that triggers it on about 30% of times I try to go back one page (on regular, live, working URLs) needs to be fixed...

Else very useful since so many websites (especially universities and governments!) can't seem to understand the concept of a stable URL!

It currently has a bug that causes it to trigger sometimes when I click the back button. I just visited the page a minute ago, it works fine when the addon is disabled, and my internet connection is fast, so I don't think it's a problem with the site.

However, apart from the bug, this is indicative of a problem with the addon design, which is that it redirects to a different page, and offers no option to exit out of the addon or try to load the original page even if the Wayback Machine addon thinks it's broken. It's okay for the addon to make mistakes, it's not okay for me to need to disable it in order to load the original page.
