Hi Rodrigo, do you use any add-ons? Could you test in Firefox's Safe Mode? In its Safe Mode, Firefox temporarily deactivates extensions, hardware acceleration, any userChrome.css/userContent.css files, and some other advanced features to help you assess whether these are causing the problem.

If Firefox is not running: Hold down the Shift key when starting Firefox. (On Mac, hold down the option/alt key instead of the Shift key.)

If Firefox is running: You can restart Firefox in Safe Mode using either:

• "3-bar" menu button > "?" Help button > Restart with Add-ons Disabled
• (menu bar) Help menu > Restart with Add-ons Disabled

and OK the restart.

Both scenarios: A small dialog should appear. Click "Start in Safe Mode" (not Refresh).

Any improvement on Google Images?

Hello! thanks for answering! Then! I only use the adblock extension. I went into Mozilla's safe mode, but the problem still remains.

Thank you for the screenshot. After the first 20 images, the URLs point to a different server. Can you load this thumbnail of a puppy:

Thanks for replying again! Yes, I can! If I open in another tab!

Does the Web Console show messages about blocked content ?

Do you see these images listed in "Tools -> Page Info -> Media" ?

Hello! I did not see it!

That first image is a 1x1 GIF image, so not much to see.

You need to scroll down below the other data URIs that show in the screenshot. These data URI seem to be the icons that are visible because they do not require downloading a file (the data URI is the image represented as base64 encoded binary data).

Thanks for answering! Would the gif look like this? GIF link: https://s5.gifyu.com/images/GIF-mozilla.gif
