Loading times of websites

[rataje]

As the title suggests, there are some sites (especially moddb.com) that have very long loading times. I've already changed the DNS address and spent many hours writing to ModDB support. But in the end I can only come to the conclusion that Firefox is responsible for this. And my suggestion for improvement is, how about if you concentrated on optimizing the code instead of changing the design countless times.

Same thing for me. But it's every website to the point its entirely unusable. Changing DNS, network proxy settings, hardware acceleration, and I've even reinstalled firefox. But it's at the point I have to use microsoft edge, and it's completely responsive, websites load in 3-4 seconds versus 30-60 seconds.

The website loading process has a lot of dwelling in the "looking up" and "waiting" stages, and slowly alternates between them as it loads elements of the website.

Do I have to delete appdata including my user data to fix this?

Would be nice if anyone can drop us a line, even if its not really a solution.
