Blocking unwanted interface elements in ChatGPT with uBlock Origin

This time last year, I was a regular user of Perplexity. Unfortunately, it began to live to its name when news items began to appear on its previously clean home page. When ChatGPT and Anthropic Claude gained the ability to search the web one after another, there was little need to use Perplexity any longer. Before that happened, I began to use uBlock Origin to block the offending panels that I found so intrusive.

However, I still retain an enduring intolerance of intrusions into clean interfaces on public GenAI tools. Thus, when ChatGPT started to offer inspiration for using it in a dropdown panel below the text box, I began to look for ways to block it. It is not as if I need ideas from others anyway; quite enough come up for me from my daily computing.

While disabling memory may help, I sought another way to turn the dropdown panel, only to find that there was none. That left uBlock Origin as my means of control. Unfortunately, OpenAI do not make it easy to block the offending insertion; Perplexity was very simple: right-click on the item and navigate to uBlock Origin > Block element... on the context menu that appears. Making the selection on the ChatGPT interface was unavailable because of how they structure things.

Ironically, I started to pursue the matter using the ChatGPT tool itself. All of this was on Firefox, so I could explore the code by right-clicking on the page and selecting Inspect from the context menu that appeared. Just viewing the source code was not an option either; obfuscation on the OpenAI end saw to that: they appear to use JavaScript to convert indecipherable symbols into code that a browser can render. There was some toing and froing before I got as far as a workable solution.

This needed me to get into the uBlock Origin Dashboard through selecting its icon on the toolbar (while I have it pinned there, you may need to click on the Extensions button in the same place as an additional step before all the steps that I describe here) and then clicking on the gears icon in the bottom right of the panel that appears. Once into the uBlock Origin interface, go to the My Filters tab and add the following code in there:

chatgpt.com##ul.divide-token-border-light.flex-col.divide-y > li.w-full

The first part (before the ## separator) is the URL, which may be chatgpt.openai.com for you. The rest selects the ideas panel while leaving the prompt text and hyperlink in place. That sufficed for me; a generic item is not as intrusive as anything built from your history or any other source of information. Naturally, the interface may change again, which might mean that I need to revisit the filter, but this works for now. We all learn as we go.
