The good: if it works, it works. It's an amazing tool to save webpages and look them up if necessary.

The bad: the 404 page has always come up too soon but lately (1-2 weeks ago) webpages cannot be saved. The error message: job failed.
No one can do anything with that information.. saving a page directly from the website works but if I cannot save a webpage with this Addon why should I keep it?

High failure rate. Needs fixing. Great when it works! I just wish it worked reliably. Too important a tool to be this unreliable.

Mozilla Firefox 96.0b6 (64-bit) — версия 1.8.6 дополнения грешит частыми ложными срабатываниями на живых, доступных вебстраницах.

Very useful when I need it, but it constantly triggers if a page is loading even remotely slow. Always triggers during cloudflare ddos protection pages.

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.

Please stop eating functional webpages!!!

This is a very useful utility but honestly #1 priority needs to allow me to disable the extension's automatic fetching utility where it straight up kills a perfectly healthy page for no reason.

For instance, I only use this page for the saving function.

This happens on an exceptionally regular basis.

@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.

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.

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

This app is pretty useful when for some reason you want to access a link that is dead or you want to read posts from a specific time in the past. However I think this addon really needs a setting to specify how long it needs to wait until it pops up, as well as a website specific disable feature, as it often breaks CloudFlare protections, popping up before CloudFlare gets a chance to load. For some websites you can just close the popup, annoying but not a big problem, however on some sites, closing the popup forces CloudFlare to restart loading, the popup appears again, and it's an endless loop. Ideally it should have an option so it wouldn't even popup, and would have an option to only load Wayback Machine if I click the addon's icon.

As others have written, on recent Nightly versions there are many false positives where it thinks the page isn't available but it is.

This is a great add-on but sometimes it shows a 'Page not available?' when the page is actually available and after installing an add-on that suspend tabs the issue got worse.

I wish this had an option to disable the auto detection or at least make it less intrusive, right now the 'offering to show archived version...' basically replaces the whole web page before you do anything.

Works sometimes, but is extremely irritating as this often opens for no reason, randomly. All features in the extension that are manual work perfectly, but the "down detection" is terrible.

This addon is good for saving webpages that might go down in the future. However... it keeps redirecting to the "You want to see an archived version of this page?" over-zealously for any page. Especially if you use the back button it will recursively keep redirecting to the extension's page.

Stop this right now or I will just report and uninstall this addon!

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.

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.

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.

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.

It will be better if this extension have a auto show option

This extension worked great for a long time, only showing the 404 detected popup when I actually encountered a missing page. However, I recently updated from Firefox 56 to Firefox 63 (which may have updated the extension too), and that caused the extension to start detecting spurious 404s, as other reviews describe. When this extension works, it is a convenient way to open the WayBack Machine, but I’m going to have to disable the extension for now until it gets fixed.

On older Firefox versions I used to use the add-on Resurrect Pages by Anthony Lieuallen. I stopped using it because it became incompatible with my Firefox version, but apparently it supports the latest Firefox version again. It may be worth checking out.

It's nice to be able to look up or save a page from the button. The automatic feature might be helpful if it was not a false positive 95% of the time. An option to turn that off would be worth a star to this review.
