Firefox adding trailing slash and the URL breaks

Question

I got a custom menu plugin in Magento2 as below.

class TopmenuPlugin {
 public function afterGetHtml(\Magento\Theme\Block\Html\Topmenu $topmenu, $html) {
 $html = '';
 $html .= "<li class=\"level0 nav-1 level-top parent ui-menu-item\">";
 $html .= "<a href='\index.php' class='level-top ui-corner-all' aria-haspopup=\"true\" tabindex=\"-1\" role=\"menuitem\"><span class=\"ui-menu-icon ui-icon ui-icon-carat-1-e\"></span><span>" . __("Home") . "</span></a>";
 $html .= "</li>";
 ....

In Chrome and IE the URL is

http://website.com/index.php

In Firefox the URL is

http://website.com\/index.php

And in Firefox I am getting Whoops, our bad... error

Is there something I am missing here????

Answer 1

After I change from

<a href='\index.php'

to

<a href='/index.php'

it works great.

Answer 2

How is your base url set? Because if your base url is http://website.com\ by accident then u will have this problem. stores --> configuration --> general --> web. It should be http://website.com/

• Malaiselvan: The base URL is already as http://website.com/
• Versdivers: Can u try clearing your cookie and cache following these steps :support.mozilla.org/nl/questions/951951
• Versdivers: Also clear the cache of the website and run php bin/magento indexer:reindex
• Malaiselvan: I cleared everything in firefox. Cleared the Magento cache and rebuilt the indexes... fyi.. I installed firefox few minutes before just for testing this issue.
• Versdivers: Can u post your php.ini settings? I know there is a settings that defines if u allow file links or not. It seems that this link has been marked as a file link for some reason and then it does that in firefox appearently. If thats not the case then i'm out of idea's xd wish u the best luck though
