 * Getting JSON error when editing popup using Firefox browser. The error does not
   appear w/ Chrome or Edge browser. Just wanted to let you know if you want to 
   test it yourself and verify. Thanks

 * Hi [@wordmax](https://wordpress.org/support/users/wordmax/),
 * Do you have any extensions installed on your Firefox browser?
 * Could you send us a screenshot of the error?
 * If you wish to send it privately, you can send a ticket at [Support Request – Popup Maker](https://wppopupmaker.com/support/#submit-a-support-ticket).
 * We’ll wait for your message. 🙂

 * Did you try it out? You should have a clean install w/ no plugins ready to test
   out basic stuff like this and avoid wasting time. Tested out w/ latest version
   of WP, no other plugins, and default theme using FIREFOX browser. This literally
   takes 30 seconds to verify.
 * Failed to load plugin url: [https://example.com/user/wp-content/plugins/popup-maker/assets/js/mce-buttons.min.js?version=1.18.2](https://example.com/user/wp-content/plugins/popup-maker/assets/js/mce-buttons.min.js?version=1.18.2)
 * Happens on firefox, does not happen w/ chrome or edge browser. Just test it and
   see. All 3 of these browsers tested are using AdGuard extension and nothing else.

 * Hi [@wordmax](https://wordpress.org/support/users/wordmax/),
 * We did try it out and we weren’t able to reproduce, that’s why we asked for more
   information. Please know that we always love to help, but we can only do that
   if enough information is given to us. 🙏
 * Here’s our test: [https://share.getcloudapp.com/nOuLK2dE](https://share.getcloudapp.com/nOuLK2dE)
 * We tested with other plugins active, so the chance for conflict is higher, but
   yet we didn’t see any JSON error.
 * You also didn’t mention you were using **AdGuard** extension at first..
 * We installed AdGuard on Firefox, but we’re still unable to see the JSON issue
   you mentioned.
 * Here’s another test for your convenience: [https://share.getcloudapp.com/jkuRA0rm](https://share.getcloudapp.com/jkuRA0rm)
 * Could you please go to **Popup Maker** > **Settings** > **Misc**. > Check the
   option “**Try to bypass ad blockers.**“
 * See here: [https://share.getcloudapp.com/jkuRA0dy](https://share.getcloudapp.com/jkuRA0dy)
 * Let us know if that helps.
