Wayback machine website and Who is domain

The context-menu shouldn't disappear when right-clicking on links. The add-on should be made to handle the URL-link that's been right-clicked on. The problem is, for example: when I click on an out-dated microsoft.com link, it's going to redirect me to an Error404 page customized by microsoft. Once I'm at that page, if I use the context-menu tool provided by this add-on, it's going to search this link instead "https://web.archive.org/web/*/https://www.microsoft.com/en-us/download/404Error.aspx". This problem will affect the user any time that the requested URL exists on a domain that has it's own error404 landing page for pages that have been removed. Since there's no toolbar icon for this add-on, it's unfortunate, but this issue makes this add-on virtually useless for me. If this gets fixed, I could see myself using this add-on.

For whatever reason, the official add-on by The Internet Archive gave me too many false positives with sites that were actually being loaded just fine. Having a right-click menu is also great: it gives me more manual control, and it doesn't make me move the mouse to the already cluttered top-right corner where I have to hunt for the right button. It works by simply opening a new tab with the result page for the search query on that you otherwise would have typed in manually>This simple solution avoids loading the font page of Archive.org when I'm only interested in a specific website, which loads much faster for me and saves bandwidth for them. Win-win! Plus, it leaves the original tab unaffected, which I like. Making it trivial to check a domain on whois is just a welcome bonus feature at this point. Thanks for a great add-on!
