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!

Like everyone else has mentioned, the add on is a little over zealous to show archived versions of the page. Other than that it is a useful add on

Works great, except for it thinking that a working site is down and asking if I want to see an archived version. When this happens I have to spam the back button until it stops thinking the page is down.

Fixing this bug and/or preferably adding an option to disable automatic missing page recognition would make this a 5/5.

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.

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!

Sometimes overreacts when page loads for a long time. I would prefer to not get modal dialog blocking page that loads correctly.

Sometimes there are false positives, and I have to turn off the add-on to view the site.

Good :/

:v

It works. Not quite as fast as one could wish, but I does it's work well. Very impressive. Looking for less clicks to save a page.

It works great but it really shouldn't prompt me to redirect on localhost.

I really wish it wouldn't pay attention to localhost. When I'm playing with my own web server I don't want to be forwarded to the wayback page. I'd rather be able to reload the classic error page instead of navigating to localhost again.
