<p>Firefox 57 and later completely removed support for already existing add-ons and moved to Webextensions, which in turn do not work on earlier versions of Firefox (and therefore TenFourFox).</p>
<p>You should see: <a href="http://tenfourfox.blogspot.com/2018/08/tenfourfox-and-legacy-addons-and-their.html">http://tenfourfox.blogspot.com/2018/08/tenfourfox-and-legacy-addons...</a></p>
<p>if it's only search add-ons you need, you can either:</p>
<p>Open preferences > tenfourfox ; then set your user agent to Firefox 60ESR (intel). Once you have installed the search add-ons you wanted from addons.mozilla.org, revert the user agent to the default one immediately. Don't do this to install anything but search add-ons.</p>
<p>or</p>
<p>Navigate to the domain that corresponds to the search engine you want and open the search bar's drop-down menu to install their search add-on. Comment #7 at <a href="http://tenfourfox.tenderapp.com/discussions/problems/8699-cant-add-any-addons-from-firefox-page">http://tenfourfox.tenderapp.com/discussions/problems/8699-cant-add-...</a> has a screenshot of this. Not all sites have this (for example, if the search add-on was created by a third party).</p>
<p>Both ways work for me.</p></div>Raphaƫl Guay
