This add-on seems to work (Firefox-ESR 140) but no longer be maintained:
- On Mozilla / Add-ons / ClearURLs
- "Last updated 2 years ago (Feb 5, 2025)"
- "Write us... If have any suggestions or complaints, please contact us on GitHub." (with link to issue list)
- On GitHub / ClearURLs / issue list
- "New issue" cannot be clicked (has no hyperlink) and its tooltip says "Issue creation is restricted in this repository". So, cannot add a new issue on GitHub … Ok, let's search more on GitHub.
- On GitHub / ClearURLs
- "If you have any suggestions or complaints, please create an issue." (with link to GitLab, not GitHub 😫)
- "[…] or email us rules.support (at) clearurls.xyz (this mail will automatically create a new issue in this repo)"
- On GitLab
- GitLab allows to create a free account, but you must give a bank account (but yeah, trust'em, it's free 😏) and a phone number. A no-solution for me.
- An e-mail sent to "rules.support (at) clearurls.xyz" gets a response "A message that you sent has not yet been delivered to one or more of its recipients after more than 72 hours". Let's try elsewhere, there must be a solution.
- On the homepage (clearurls.xyz)
- "Last update: February 5, 2025"
- No contact page linked. No site map to find where it can be.

Nope, I've run out of solutions.

So basically, good in the current state of the web (2025~6) but as more time passes, the worse this add-on will be.

it's useless

Abandoned. This app hasn't been updated in almost two years as of August 2026. CleanURLs is a massive security risk that leaves users machines and data extremely vulnerable to attack. If still using uninstall and rate 1 star to get this abandoned ware out of suggested addons.

Honestly, it just really, really needs a basic site whitelist option. Sometimes you don't mind the things this targets because they are actually necessary for functionality. Good example: When I go to my health insurance web portal, a different company handles the online payment. When I click to pay on web portal, it opens their website, and uses a lot of things ClearURLs auto-cleans to tell that payment site who I am without me needing to explicitly log in, and in fact doesn't have a normal log in method for said site, so I have to turn of ClearURLs... to pay online for my health insurance.

This is far from the only situation I've ran into with this.

For a while I had some issues with websites, after a while I started checking what was ruining it. I came onto this extension, the reasons I found is that it too aggressively kills script or cookies or whatever a extension fx google.ai relies on (google search engine) The idea behind the extension itself is good but the function and the use i need it for did not help. This extension did mess it up a bit so.

It hasn't worked properly with Google since the FireFox update. A tracking link will be created in Google search results. Use Don't Track Me Google.

Works ok, but it also breaks AI Overview in Google Search.

In general I really like this addon, but it caused a memory leak that would eventually use all of my memory and would cause my computer to go unresponsive. I tried disabling addons one by one, and my memory usage upon disabling this addon went from 40GB to around 7GB with many windows open. I'm sure I found some edge case here, but I've had to disable it for now.

Disables AI Overview on Google

Very useful. After the question mark ("?"), the rest of the link is very likely completely useless and is made of parameters. Some time ago, my brother clicked on a link with more than 10 defined parameters including my f***ing location and device! Not only that, but this will be very useful for Youtube now that Google is filled with AI tracking...

The colors and overall UI is not like those old extensions that have 2000's style, it is actually very clean and it's worth it to pin this extension.

This app is generally useless. It does nothing. For example, I want to share a youtube video without trackers. I press the share icon then press copy url then i paste this url in the massage box to send it to my friend. And this app changes nothing. In the message box url will be the same. For me it is just easier to remove text after question mark in url to remove tracker part of url. So i really don't get. Does this app even work? Or maybe url clipboard checking is not enabled? Then how do i turn it on? So nope. I had enough. I will not use it.

Causing Google Search AI Overview to stop working.
