@Keffori Did you perchance forget to follow step 2 under Install? I'm able to reproduce the error shown here when I forgot to set the browser.urlbar.maxRichResults to 0. Tip: Instead of doing it via about:config, you can also set it by adding a user.js file in the same profile folder as chrome is in (Note: not in the chrome folder). In the user.js file:

// Enables CSS themes
user_pref('toolkit.legacyUserProfileCustomizations.stylesheets', true);
// Hide search suggestion pop up
user_pref('browser.urlbar.maxRichResults', 0);
// Allows URL selection in a single click
user_pref('browser.urlbar.clickSelectsAll', true);

Note on pasting images on Github, you can simply paste them directly (either by right clicking in the text box > Paste) or using the Ctrl + V shortcut (on Windows) directly, and GitHub will handle that for you.

After more tinkering, I did stumble upon this same exact issue if Only Show on New Tab option is used for the bookmark toolbar, even with browser.urlbar.maxRichResults set to 0.

See image below:

The problem goes away when "Always Show" is used though.
