Firefox becomes very slow or stops responding when viewing shop drawings

more options

I run a drafting site where we share shop drawings for contractors and architects: https://usadraftsman.com

Whenever I open these drawing preview pages in Firefox, the browser gets slow or sometimes becomes unresponsive. The same pages load completely fine in Chrome, so I’m trying to understand what might be causing this only in Firefox.

Most of the previews are large drawings or viewer embeds, so maybe Firefox is struggling with rendering them. I tried clearing cache and turning off extensions, but the issue still comes back.

If anyone has dealt with similar heavy graphics or rendering issues in Firefox, what should I check or adjust? Any suggestions would be appreciated.

What version of Firefox? What security software besides MS Defender are you running? Windows home or pro? If you're running Windows Pro version, I would test in Windows Sandbox to confirm. https://www.howtogeek.com/399290/how-to-use-windows-10s-new-sandbox-to-safely-test-apps/

The site doesn't allow me to access any samples. Hard to help with something we cannot see or replicate. Show your system specs by posting a screenshot of the performance tab in Task manager.

Here's a little research on rendering.
