 * WP5.8
    Windows 10 OS Only affects Firefox (90.0.2)
 * Whilst explaining a technique to a new web-editor I found a problem with Select_All
   using Firefox.
 * Go to Dashboard/Appearance/Theme editor and select any long file
    Click on the
   file contents
 * Then try each of these methods…
    Control + A – this correctly selects all text
   to the end of the file
 * These methods are different
    Edit/Select_All – only selects first part of file
   Right Click Menu/Select_All – only selects first part of file
 * The Plugin Editor is the same.
 * Is this a Firefox problem or something within WP ?

 * What do you mean with a long file? A file that’s longer than the page?

 * > What do you mean with a long file? A file that’s longer than the page?
 * Yes
 * The specific problem is if you want to replace the file with new content.
 * Normally you can select_all, delete, paste in the new content and update.
 * If select_all only selects_a_bit then it becomes a bit more difficult.

 * Thank you for clarifying Jim. I’ve tested it and get the same result as you.
 * So indeed, in Firefox, in the theme editor, if I do CTRL + A, all text in the
   editor gets selected. But if I right-click and do ‘select all’, only the visible
   portion of the text gets selected.
 * I’ve done some more testing and can confirm the following:
    1. This doesn’t happen in for example Edge. There, in both cases all text gets 
       selected.
    2. It also doesn’t happen in Firefox on plain html webpages. I’ve created one with
       a long text and many paragraphs and these all get selected just fine.
    3. It also doesn’t happen in the WordPress editor in Firefox if you have a long,
       continuous block of text (or code) without any line-breaks (white lines) in 
       between. You can try this by minifying your code first (you could for example
       use an online minification service for this) and then trying to select all of
       it
 * So it seems to me this issue is specific to WordPress in combination with Firefox
   and [possibly a bug](https://make.wordpress.org/core/handbook/testing/reporting-bugs/).
 * When I have some more time I’ll do some more testing and if it turns out this
   is a bug, I’ll report it.
 * Thank you Jim for pointing this one out.

 * Thanks for taking the time to check it out.
 * I was concerned that it might be local glitch.
 * It is strange that Chrome is unaffected – you would assume that all the select
   options would use the same command.

 * I have now found additional problems that I think may be related to the CodeMirror
   coding used by WP in the Theme Editor.
 * Firefox only issue:
    Select a number of lines of code from the file content and
   right_click_menu/delete then right_click_menu/undo note that the first line of
   the code is missing
 * Firefox and MS Edge issue
    Conduct a “Find in page” search within the file contents.
   Note that only the first part of the file content is searched.
