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.
i would love to disable the automatic modal, it sometimes pops up even if websites load successfully (some interference with adblockers probably), which is annoying. yet i would love to have the toolbar icon.
Note that the current version is very outdated, three years out of date now.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.
Works great, except for it thinking that a working site is down and asking if I want to see an archived version.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.
