Is there any way to highlight every uppercase character on a page like when we use the "Find bar" using Ctrl+F ?

Chosen solution

Hmm, I don't think there is a built-in way to do this.

There are some add-ons that allow Regular Expression (RegEx) searching in pages. Here's an example I just tried out for a few minutes:

https://addons.mozilla.org/firefox/addon/regexsearch/

To find the pattern of all capital letters, your query is

[A-Z]

You check the box for global. Then click Highlight. Screenshot of the result attached for reference.
