Firefox Community Forum

Hi Mozilla community,

I’m experiencing some slowdowns in Firefox whenever I browse image-heavy restaurant websites. A recent example is when I tried to open the Tim Hortons lunch menu—the page took longer than usual to load, and some images weren’t displaying properly.

I’ve cleared the cache, checked extensions, and even tried private browsing, but the issue still persists. Could it be a rendering or image handling setting in Firefox that needs adjusting?

For context, here’s the exact page I’m referring to: 👉 https://timhortonsmenuprices.ca/tim-hortons-lunch-menu-with-prices/ – it’s pretty detailed and might help illustrate the problem.

Would appreciate any tips or tweaks to optimize Firefox performance for this kind of content. Thanks!

As the Subject line says, Firefox will act like it's working normally for a little bit but shortly after using it websites stop loading and no new websites can be accessed. Usually after about 10 minutes. Closing and reopening Firefox restarts the cycle. Works for a bit, then stops. Other browsers like Microsoft Edge and Google Chrome work fine.

I've checked my Firewall, deleted and re-added Firefox, made sure it had both Public and Private Network access. Also tried using Firefox in Troubleshoot mode and tried resetting Firefox. Same behavior, made no difference.

I don't see any error messages when this happens. Tabs just spin and load indefinitely with nothing ever appearing in the window. Anyone have any ideas?

I am having issues with sites, where I can access main page but then when i try to move onto another area of the site I just get spinning. I have had this on different sites, from Amazon, Disney. I have tried clearing cache, i have made sure Firefox up to date but can be very sporadic.
