Hi, Linux Manjaro with KDE. X11.

I just saw another questions with a similar issue regarding crtl+r and they're working on websites. https://support.mozilla.org/en-US/questions/1377142 What are you doing and can we replicate the steps?

Thanks, I read the article and it's my same problem. sometimes work and often doesn't work.

Do you use a bookmark that has some GET data appended (?xxx=xxx)?

You can try to remove such trailing GET data

If you use a bookmark to access a specific page then instead navigate to this page starting with the main page or with the sign in page in case there is a problem with this bookmark.

I don't know what is "GET data appended". sorry. The webpage is mine and I access to it directly. the problem happened also with other pages

in randomic way.

The other question was solved by the discovery that an extension was causing the problem.
