Scroll doesn’t work in Firefox

Turns out it is pretty hard to find out what’s going on, guessing may also be a result of changes in the browser… Still trying to replicate it consistently.

A workaround for now is to turn off (uncheck) the “Enable full-height editor and distraction-free functionality.” checkbox in Screen Options.

Is there a remedy to this yet?

Think I got to the bottom of it. Seems this is a timing issue with the TinyMCE initialization and the DOM ready on the old Edit Post screen. Added a patch on trac: https://core.trac.www.ads-software.com/attachment/ticket/52046/52046.diff. Please test it if you can, and add a comment whether it fixes it or not on the trac ticket: https://core.trac.www.ads-software.com/ticket/52046.

I have just checked.
It is still a problem.

I am a bit confused on where to look for :

src/js/_enqueues/vendor/tinymce/plugins/wordpress/plugin.js

It seems there is not such directory on my installation.

@mixos ugh, sorry, I should have explained better. To test a patch you’ll need to have a development environment for WordPress. That’s usually a “local” install on your computer and needs a lot of extra dev. tools like svn, git, npm, grunt, etc.

Alternatively if you have a “staging” feature or a test install on your web host you can use the WP Tester plugin to test the latest code. Currently this is WP 5.7-alpha. Just keep in mind that’s not recommended for a live site. Going to commit the above patch so it will be possible to test that way too.

hm, any way i can test it on my hosted installation for the non developers ?

I could make the changes manually , if i could find the desired file.

I still have the same problem, using the latest Firefox.
What I have found out is, when I press ctrl+f5 in the edit screen, the top bar becomes sticky again. But as soon as I click on update post, it’s stucked to the top again.

@mixos to make the changes manually (not recommended especially for a live site):

1. Download these two files from the built WP 5.7-alpha:

   https://build.trac.www.ads-software.com/browser/trunk/wp-includes/js/tinymce/plugins/wordpress

   and upload them to your install at the same location: /wp-includes/js/tinymce/plugins/wordpress replacing the existing files there.

2. Download wp-tinymce.js from https://build.trac.www.ads-software.com/browser/trunk/wp-includes/js/tinymce, and replace it in your install.

The first case is for when using SCRIPT_DEBUG. Then you’ll have to refresh browser cache/reload the page few times while holding Shift. Also keep in mind that this may trigger warnings in security plugins, etc.

I went with option 2 and it worked right away.

Will this change/fix/patch be in place on the next WP release ?

Thanks for your kind help on this.

This is not an issue with FireFox.

+1 for @mixos’s question. Will a fix be addressed or is the workaround the only option for Firefox users?

@azaozz – thanks for the great plugin! ??

Am getting the same issue in Firefox. I see issue #52046 looks like a potential fix, but hasn’t been merged into an update yet?

When will the plugin update come out? It is very uncomfortable to work without the upper and lower bar fixed

Two months, a new build today referring that bug as fixed and still not working.
Running classic 1.6 and wordpress 5.6.1.
