= in URL changes into %3D

I have url with parameters in my static web page

https://www.nejlepsi-skolky.cz/list-map-of-kindergartens-seznam-mapa-skolek-jesli?locationFrom=Velk%C3%A9%20Opatovice,Dlouh%C3%A1%20429;latFrom=49.6120414733887;lonFrom=16.6786785125732

the problem is that the second and the third equals signs are changed into %3D, when I click on the URL. Is there a possibility to say to the browser not to change equals? And why the first equal works fine?

I have found some answers about nginx, but this is just static site not connected to nginx settings.
Thank you

EDIT: Problem was caused with saving the page to the local storage. During the save the & signs are being changed by firefox into ; signs

This is normal. It should not be a problem if you are reading the URL with something that supports the standards.

And why the first equal works fine?

The standard format of a query string is a series of key=value pairs which are separated by & characters.

Older versions of the standard supported ; as well as &, but they are obsolete.

= signs, being the symbol that indicates the end of a key and start of a value, should be encoded as %3D when they occur inside a key or a value.

The first equal in your example is the symbol that separates the key from the value. The second is data inside the value.

Is there a possibility to say to the browser not to change equals?

Change your URL so you use & as the separator instead of ;.
