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.
Same issue as everyone else. You *cannot* throw a splash screen in my face every time a page fails to load properly. Have some respect for your user base - if someone is familiar with the Wayback Machine and chooses to install this extension, chances are they know how to navigate to the archive for dead pages via the widget! Please add a toggle. This is an issue I would have expected the Archive Team of all groups to be savvy to. My primary reason for downloading was to be able to quickly save websites and contribute to the archive. While this extension makes that slightly more convenient, I would recommend that anyone seeking similar functionality just memorize this to prepend to the address of whichever page you want to save: "https://web.archive.org/save/". If you're more interested in the other function, you can instead prepend "https://web.archive.org/web/*/". Other people have suggested that the page-down screens be converted into banners, and while this would be a huge improvement, I would really like to be able to disable all popups regardless of "intrusiveness." Again, this seems like something you guys would be sensitive to! I can't understand why it's designed this way.
Can't use it: detection of down webpages gives too many false positives. And it messes with browser's history replacing original URL so you can't just click "reload" or "back" to get back to original URL. Have to uninstall.
This extension is SO useful that I've put up with the awful automatic page-down detection for ages. But it's just gotten worse and worse. It doesn't even wait for the server to respond before redirecting to the page not available prompt!
I can see that this is the number one most complained about feature -- all you need to do is add a toggle so that we can disable the automatic redirects. That's it! If I could have this extension without the automatic redirects I would instantly give it five stars. I love archive.org and the Wayback Machine but this extension needs some love!
I absolutely love internet archive and wayback machine, and I wanted so much to love this extension. But unfortunately it keeps giving me a crazy amount of fake positive unavailable webpages sometimes before it even tries to load, ruining my navigation in almost every session. So why not just turn down the option of automatic detection and replacement of these pages and just keep the other great functionnalities ? Because you just can't, you also cannot just reload the current page you were trying to reach when the extension find a fake positive, you re just stuck. So uninstallation is the only way to go. As long as this extension is not fixed and give absolutely no option to turn down the messy automatic error detection, stay away from this extension.
Great and horrible addon. Horrible because the dead page detection has been nothing but false positives for the months I have used it. Great because everything else works as well as one could hope for. The dead page detection really is bad enough to make me uninstall an otherwise 5 star addon because it makes the overall browser much much worse. It would be a solid 5 if that detection had never been built in.
The functionality to archive and look up archived pages with this extension is great, but it need the option to disable the automatic detection. It is a false positive 99.9% of the time, and it stops the page from loading properly.
Great extension, but it *very often* replaces 100% functioning web pages with its annoying "Page not available" dialog box. I usually reload the page to fix this but I don't even understand how it's possible to mess up reading an HTTP status code... An less intrusive solution would be to show a banner.
Once worked fine, but for the past few months, it has got "Fail with status: 498 No Reason Phrase" error with Retry button, which fails all the time on firefox (waterfox as well). So, now this extension is quite useless and needs to be updated.
@treesap - thanks for the link to github wayback-machine-webextension 3.0. Me too had problems with the 1.8.6. version here. Did you manage to install the github webextension lasting longer than just temporarily? I failed. Every time I reopen my Waterfox (version G-3) the extension is gone.
