P.S. thanx for destroying the Firefox design and layout . . .

Hi,

The people who answer questions here, for the most part, are other users volunteering their time (like me), not Mozilla employees or Firefox developers. If you want to leave feedback for Firefox developers, you can go to the Firefox Help menu and select Submit Feedback... or use this link. Your feedback gets collected by a team of people who read it and gather data about the most common issues.

You can also file a bug report or feature request. See File a bug report or feature request for Mozilla products for details.

Seriously, it takes 3 minutes that Firefox start loading websites.

Do you mean nothing happens, or it takes a long time for the page to load?

Start Firefox using Troubleshoot(Safe) Mode {web link}

A small dialog should appear. Click Start In Troubleshoot(Safe) Mode (not Refresh). Is the problem still there?

It takes a long time for the page to load. There's just a "loading icon" in the tab, it takes around 3 minutes to load the page. The Firefox opens in 2 second but the loading of the pages start after some time.

I tried "safe mode", it's the same. I found solution that I need to delete something from "C:\Users\X\AppData\Roaming\Mozilla\Firefox\Profiles" but let's be serious, Im not gonna do this everyday because it helps only for few hours.

Use these links to create a new profile. Use this new profile as is. Is the problem still there?

Forgot to ask. Are any other web use programs having problems? Contact your ISP and have them test your service

Issues with checkboxes can happen if you have set "browser.proton.enabled = false" on the about:config page to disable Proton.

In Firefox 91+ you can no longer disable Proton and revert changes that come with this design via "browser.proton.enabled = false" on the about:config page. Best in Firefox 91 is to set browser.proton.enabled at its default value true as the false setting can cause issues with checkboxes.

In Firefox 91+ you need to use code in userChrome.css to override changes coming with the Proton design.

This is no ISP problem because I have this problem on various ISP. I have no problems with any others programs.

For me it's C:\Users\X\AppData\Roaming\Mozilla\Firefox\Profiles\x0z6ltji.default-release-1625866142922\datareporting\archived after delete content of this folder, everything's fine (for some time)
