Install this from the official GitHub repository, unless you want a buggy 3 years old release. The newer version has an improved UI, bugfixes, and more features. 5-stars for that version!

Old review (for this version): Super useful tool, but BADLY needs a bugfix. I basically have to keep this disabled until the times that I need it due to a significant bug that has been there for the 1+ year I've used it.

The issue is that sometimes the "Page not available" page is displayed for pages that are absolutely available! And the extension is very persistent--after this bug hits, the only way to view the live version of the webpage is to manually navigate to it (i.e. copy and re-paste the portion of the URL that contains the page I'm trying to visit—minus all the archive.org stuff.)

I periodically re-enable the extension to see if the problem is fixed, but no luck for the past 1+ years.

Comme dit plus bas : I love the internet archive and the wayback machine, but I had to disable this extension because it constantly gives me false positives and won't let me see pages that are live. At the very least it needs a button to "Show Live Page" so I can override it. But as of now it's impossible to override without disabling the extension entirely.

the new autosave feature rocks.

Excellent extension, it's super useful.

Note that the current version is very outdated, three years out of date now. The github (/internetarchive/wayback-machine-webextension) shows that there is very active development, but changes are not being published to firefox like they are to chrome.

Really good, if site is not available but is saved, a pop-up appears asking if you want the saved version with a button to the link.

Frequent false positives, obstructing access to working websites.

It does what it is supposed to do, but also does it WHEN it is NOT supposed to. It is often triggered when my (overloaded) browser takes a bit longer to render a page, which is VERY annoying. What makes it worse, sometimes pages REALLY timeout if the server is down and this extension doesn't react to that. The additional minus point is the lack of any configuration options to, say increase the timeout or completely disable that "feature". Besides that, it would be nice to have it work from the context menu on links so the target pages could be instantly looked up on the Wayback Machine. All being said, I don't have much hope any of this will be fixed as I've seen many people have complained about the same problem and nothing has happened...

No option to modify how the app functions -- only enable/disable. Pops up MUCH too often, and seldom for the pages that I actually want to check the archive.

Very intrusive. Sometimes replaces entire webpage before it gets time to load.
It says it detects _annoying_ 404 pages and ironically itself is very annoying.

Acts too aggressive, often falsely, replaces the whole page instead of showing a popup or something unintrusive.

The “Page not available?” site opens even for some sites that work perfectly fine and prevents visiting these sites completely and this feature can't be disabled in favor of only manually visiting a site's archive.
Also the context menu entry only works for the current page, even if you right-clicked a link. I would've expected to be taken to the archive of the site the link leads to, but that could just be me.
