Looks like this is working. Couldn't reproduce, can you try again on your end and let us know if this continues to be an issue.

Latest update doesn't break anything.
Instead I am asked if I am a bot.
This doesn't happen on Firefox or Chrome.

This error message comes up because we block their tracker. https://www.gumtree.com/ycxwzbcsxennhrkc.js . Not really prepared to remove it for privacy. Occurs in any browser using an Adblock extension.

Not able to reach www.gumtree.com to test this

☹️

Closing - let's re-open if the site comes back up and we can test. Per last comment it seemed to have been working?

Hi @rebron I didn't want to have to create another similar topic again seeing as the issue I'm about to report is linked to this website and also presents an error.

Attempting to enter the login or password of this page (https://my.gumtree.com/login) over utilizes the cpu and occasionally freezes the browser, however, I did notice that after 4 or 5 minutes every time the page does eventually allow you enter your ID.

Steps:

• Go to login page of gumtree.com
• Try to input user or pass and it will allow you to enter a few keys but will then will freeze
• Wait 4 or 5 minutes without doing anything else
• It should the give some sort of indication that it will work. I find out when the cpu calms down
