I have websites that are blocked on one of my computers and not another. Why? VPN is not on. Server Not Found

Firefox can’t connect to the server at link.mail.beehiiv.com What can you do about it?

Try connecting on a different device. Check your modem or router. Disconnect and reconnect to Wi-Fi.

I just noticed today that I am not getting anywhere near all of my Yahoo email, and most of my past emails that I had not deleted have disappeared. An automatic update did run yesterday, but I have made no recent changes to Firefox. I checked Chrome, and all of my emails are coming through. I have tried restarting the pc and refreshing Firefox, and a couple of other things Firefox AI suggested, but none of them worked. Any suggestions?

Hi everyone,

I run a construction estimating construction estimating website where we share project-based cost estimates and detailed breakdown for contractors, architects

I’ve noticed a weird issue in Firefox lately.

Some of the heavier pages (especially ones with large tables, detailed breakdowns, and embedded content) start getting really slow or sometimes even become unresponsive in Firefox. The same pages load completely fine and smooth in Chrome, so I’m trying to understand what Firefox might be struggling with specifically.

I already tried the basic stuff like clearing cache, testing in private mode, and disabling extensions, but the issue still keeps coming back.

It seems more noticeable on pages with a lot of structured data and embedded elements, so I’m wondering if it could be a rendering, memory, or layout issue on Firefox’s side.

Has anyone dealt with similar performance issues on Firefox with data-heavy or content-heavy web pages?

What should I look into next — layout structure, CSS rendering, JS execution, or something Firefox-specific I might be missing?

Any guidance or debugging tips would be really appreciated.

My files are stored on external hard drives within Dropbox. The hard drives are mapped to my computer. I can no longer attach files from these drives to anything through Firefox. I can still attach through Chrome, Bing, Safari etc. Any suggestions how to solve this problem. I am NOT attaching through the Dropbox website. I am attaching through the full path showing drive etc. Thank you.
