Useful for when you want to make sure the pages you're reading will still be around in some form in the future, and to easily get at additional context. (Just remember that it checks *every page you view* against the Wayback Machine, so turn it off when you're not using it!)

If you enable auto-save, be sure to add to the exclusions list so it doesn't waste time trying to archive your webmail or control panel.

There *is* a private mode where it doesn't do anything until you ask it to. But that leaves you with essentially the same features as a pair of bookmarklets to check or save the current page.

It's a staple addon for me. Could use some enhancements: e.g. more granular auto-save period config, RegEx support for blacklist, and also allowing to use a whitelist and/or an "always enabled for saving" list.

Convenient

Generally works well. It falls short in:
- Frequently auto-updating and then not operating at all until the user agrees to new permissions, which is a drag on workflow.
- Persists in annoying me with pop-up boxes to "check out more great features in settings," which is obnoxious when commercial software does it, let alone when a utility put out by a non-profit does. It should do its job and get out of my way.

EDIT: It was finally updated, and although it still is susceptible to false positives, it's greatly improved and extremely useful now!

Same complaint as everyone else: this addon would be SO useful if there was some way to dial down the sensitivity of the automatic redirect or turn it off — but since the addon hasn't been updated since 2018 I assume this bug won't be fixed. Hopefully someone picks up where they left off and implements this functionality into a working addon, because it's a great idea.

It's good but sometimes has false positives and thinks that a website is down when it isn't. In those cases there's no way around than to disable the extension. I wish they'd fix that.

But it's absolutely brilliant work the Internet Archive team are doing.

I would like to see the option of a banner rather than a pop up. Other than that, great add on.

ポップアップページがやや不快だが、ウェブサイトを手軽にセーブできる点は本当に優れている。
ただ私の環境の影響なのか、Twitterのウェブページが正しくアーカイブされない。惜しいところだ。

サポートが終了して消えてしまうようなウェブサイトがあり、まだ閲覧していたいという気持ちがあるなら、この拡張機能をぜひ試してほしい。

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Note that the current version is very outdated, three years out of date now.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.

I love this extension, but false positives in recent months have been really annoying, I sometimes needed to press Back up to five times to just be able to see the page I was reading.

As others already mentioned there's a bug where it thinks the page failed to load when it didn't. If you just provide the option to disable this auto detection it would be great.

Lately it seems way too quick to jump to a wayback lookup when clicking the 'back' arrow button on Firefox. I'm just jumping back to a page that I had just looked at! It isn't 404!
