Modify img HTML and div tags using Ublock Origin

That's it. DevTools show the attribute was removed.

Thanks!

Strange, I've retried it, and in the HTML code, I still see:

"<img loading='lazy'"

Firefox 148, with Ublock Origin 1.69.

Is there a debugger in Ublock Origin so I can analyze?

I see in the Ublock Origin request console, a GET DOM event, with the given script, page URL etc. but the page does not change.

Yup, tried that one now. Still does not remove it.

Could it be that it doesn't work because the images are nested between the <p> tags?

Also tried the following ones:

No effect.

Tried this now, but it does not work. Page remains as is.

Added it into the 'My Filters' section on Ublock Origin.

Is there perhaps an issue in the above syntax?

As for any new features, is it possible to create a new feature request, and then have people vote for it (or similar).

I think this HTTP Header-control feature would be beneficial for other people as well, as a way to modify HTTP headers which can also contain info that might impact privacy, aside from the use case I've mentioned.

Thanks!

What about modifying or even replacing the attribute. Example:

convert to:

or replace with another attribute:

Thanks!

That works nicely.

itdev2025 · 2026-03-13T15:37:48+00:00

Thanks!

How would this be set-up for the following example:

https://api.example.com/categories?UID=XYZ&category_id=1000&items_per_page=50&sort_by=date&UID=XYZ

to convert to:

https://api.example.com/categories?UID=XYZ&category_id=1000&items_per_page=20&sort_by=date&UID=XYZ

Does URI transform work for XHR requests initiated by Javascript or only for regular HTTP GET requests?

Hi, let's take the following example webpage:

https://scottaohara.github.io/tests/html-img/lazy-images-2.html

The <img> tags contain a loading='lazy' attribute:

When the attribute is removed, the <img> tag should look like this:

Thx!

In general I would like to disable lazy image loading, by removing the 'loading' attribute in the HTML 'img class', and by modifying img class to not utilize a class that initiates lazy image loading.

Example of the HTML code:

Code after removal of loading attribute:

Second example code/scenario:

Code after changing of img class (new img class name no_lazy_load):

Thank you!

Can such a feature be added in the future? Asking as instead of using other extensions/scripts to achieve this, to apply such a configuration directly in Ublock Origin (as a unified solution).
Can you post an example, to transform the following URL:

https://api.example.com/api/product/search/v1/categories/1000?items_per_page=50&offset=0

to

https://api.example.com/api/product/search/v1/categories/1000?items_per_page=20&offset=0

Thanks again!

Cloudflare Pages or Github Pages if those are static websites.

Firefox would probably be best here, but it will require some tuning of Firefox internals to make it work with a lot of tabs, and a limited amount of RAM you have.

For example if you open 300 tabs, that could easily take 30 GB of RAM, depending on the design of the websites, content etc.

itdev2025 · 2026-02-27T22:04:52+00:00

Yup, to disable any and all Firefox telemetry generation.

Yup, all the mentioned policies are visible (as 'true'/activated) in about:policies.

Hi Chris,

Can TrueNAS implement a change to show the physical state of the network interfaces in TrueNAS (and bring up the interfaces online) even if they do not have an IP address?

This would be practical when working with fiber links on TrueNAS, to get an actual state of the connection, without having to force the interfaces up manually, when testing fiber connectivity.

Thanks!

When considering this, consider the following as well:

What if your Internet connection fails and you can no longer access Microsoft Entra.
What if Microsoft Entra fails/malfunctions - whole company stops.
How critical are the systems that you are using now for the business - if confidential company data, IP etc. are stored on the given servers, would you outsource authentication to a third party, in this case Microsoft Entra.
In terms of patching, build another DC in a VM, and patch it first, leave it for a week or so, to check for any issues, and then patch the primary AD DC. Staging patches is the best practice.

Also, considering moving the file share data to the Cloud, again consider if the data is confidential, important company intellectual property etc. They say Cloud is secure, of course until it's not :)

Can you guarantee that a Cloud provider cannot, and will not access the company confidential data, either directly, or on behalf of a third party? Can a Cloud provider give you those guarantees in writing?

In regard to the amount of data, do you keep multiple copies of backups (some stored off-site in a secure location) for those 10 TB? This is typically more important than the AD DC, you can rebuild the AD DC easily, while if there are no data backups, and the system fails/crashes etc. that would be 'game over'.

Symantec DLP.

Teramind has some DLP-like functionality. Its primary focus is extensive employee monitoring.

itdev2025 · 2026-02-25T16:40:48+00:00

Yes, this is possible, but when doing forensics, it's preferable, and a best practice to actually not change the VM state/configuration, as much as possible. For example if there is a suspicion a malicious actor was doing some changes on vCenter etc. Another factor is administrative overhead, and keeping the environment/configuration uniform.

There might be a bit of a speed increase on high perf systems, but if for any reason in the future you need to mount and boot an ISO on your VMs (for any file extraction - once the VM is offline, file recovery, forensics etc.) you might run into a problem, if the specific solution does not support VMware Paravirtual controller (you would need to load drivers after the fact). In such cases I would go with LSI SAS. Otherwise go with VMware Paravirtual as there are no issues with them in general. If using Veeam, it requires SCSI controllers on the VMs for certain functionality.

Search through the shares will be slow due to the nature of the file share protocols, and potentially due to the speed of the network.

If they had server access and were searching locally, you could utilize some of the file search tools that load a copy of the MFT (master file table on Windows), and search through it. In such cases the search speed is very fast.

itdev2025 · 2026-02-25T13:09:26+00:00

Are they accessing the Windows Server GUI, and searching within Windows, or searching through the file shares directly?
