I was previously using a different addon, Neat URL. I disabled that one so I could give ClearURLs a proper try. However, I realized that every time I restart Firefox, ClearURLs gets disabled, and Neat URL is re-enabled. Suspecting some sort of misbehavior from Neat URL, I fully removed Neat URL. However, even after that, ClearURLs is still showing as disabled in my addons list every time I restart Firefox. What's going on? I've never seen this behavior with any other addon.

EDIT: I figured out what was going on. Back when Mozilla had the certificate debacle that resulted in addons getting disabled en masse for everyone, I made my extensions.json file read-only as an attempt to keep my addons forcibly enabled. After the official fixes from Mozilla, I forgot to uncheck "read-only" from extensions.json. ClearURLs was the first new addon I've tried since that time. Anyway, when I tried to disable all my addons as a test, they came up as re-enabled when I restarted Firefox. That's when I finally suspected my extensions.json. So, I realized that was still read-only. Fixing that, now everything is working as expected. I'll update my ClearURLs rating to 5-stars.

A well written, good looking, easy to use, add-on.

On checking the log, having used ClearURLs for some time, it was great to see how it was busily removing tracking info from so many links.

Thanks to author from a happy user in Scotland!

Great work indeed.
Thanks.

I have encountered an odd problem with my browser that it loses connection every time I play an embedded media (e.g. YouTube) on a webpage. After scanning my computer and testing my addons one by one, I have found that the problem only exists when this addon is enabled. I have used this addon for quite some time and it is a recent problem.

Edit: I haven't been able to reproduce this issue since updating to the latest version today so I'm giving this addon 5 stars instead. It has been really helpful in keeping the URLs clean.

works great!

Excellent addon for those who value privacy. It has a box to batch clean a collection of dirty links, context menu to copy clean link. It would be the best if it offers custom rules in future. You can always report it to the developer. He responds timely and efficiently.

Thank you, Kevin. Excellent companion for my Firefox.

Excellent extension with very responsive support!

Very useful.

I like the addon. It looks good, it does what it should. What more do you want?

Kevin, I have run into another issue with ClearURLs. It seems to block the map on the left side of the property search result on zillow.com. This occurs when looking at a saved map search or a new map search. Could you please check this?

Maybe you could consider a way to allow the user to whitelist certain sites when issues like this crop up.

ClearURLs is a must!

Why this and not other similar add-on?
Most of the other adds-on have around 13 rules to remove garbage fields. But ClearURLs has 65 rules to remove garbage fields and much of them are regex-rules (so the rule does not only block one field, it blocks all fields with the same structure). Also, ClearURLs is a open source.

If you are a kind of average user looking to improve privacy without loosing a decade studying a PhD in tech details... ClearURLs is the most complete ready-to-use plug-and-play alternative.

I would like to suggest future requests to the author:

1) To test the system performance impact of the 65 rules. I don't have know-how to distinguish if the 65 rules are indispensable. If "yes", then keep all and add more rules! But if some of them are exceptional and affects system resources/performance, then it could be interesting to prioritize system performance.

2) To evolve ClearURLs in an all-in-one add-on for URLs nasty issues ("clearing", "redirecting", "skipping" etc).
I perfectly understand the author' point of view, in the sense that some requests demand tons of work, not just for build the add-on, but also for keep it updated, supported etc. But from the user' point of view, less adds-on, less system resources, better performance etc... is always more than welcome and most desirable.
I will be more than happy to help donating for this kind of all-in-one add-on.

Congrats and thank you to the author!
