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.

Non of the torproject.org site load on firefox they timeout. How do I access the torproject.org domains?

I cannot get the free VPN to turn on. It keeps looping me back to sign in and then tells me to turn it on and then it loops back to the sign in and continues to loop

So, I'm not exactly sure what's going on. Whenever I try to turn on Firefox's built-in VPN, either it tells me I cannot connect and to try again in a few minutes, or it just does not respond at all. I know this is vague, but it's literally everything I can muster. I looked through the settings, and nothing there helped.

Firefox Image Display Problem with Grok / xAI ChatI'm using:Dell computer Windows 10 Firefox (latest version)

Problem: Grok-generated images (graphs, memes, translated election charts, etc.) do not appear at all in the chat. I only see blank spaces or broken image icons. Right-click → "Open Image in New Tab" and Ctrl+Shift+R (hard refresh) do not work.This issue started during a long conversation where Grok was creating multiple JPG versions of an election results graph with translated text.Note: The same images load fine in other sessions/browsers, but I prefer to stay with Firefox. Is this a known compatibility issue with Grok's image rendering system in Firefox? Any settings, extensions, or workarounds (without switching to Chrome or Edge) that can fix it?

My Mozilla Firefox browser is not working. It does not open when I try to start it. I have restarted my computer, but the issue still persists. Please help me fix this problem.

the problem started 2 or 3 updates ago. I keep hoping the latest update will fix the problem. I can still access using Chrome. I've tried clearing cache and turning off ETP
