Hey there!

Can you convert your language into English so I can help you better?

Thanks!

Yours sincerely,

Yup, sure i could not make a screenshot from "Restore session failed" because firefox now restored session after turn on. But i dont understand why - this option is disabled in settings

Hey there!

Well based on the screenshot you sent it looks like your organization is managing your Firefox browser a bit. So what happened was your organization only allows you to use Firefox (well at least it's the default browser).

Try the following:

(1) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button promising to be careful or accepting the risk.

(2) In the search box above the list, type or paste SHELL and pause while the list is filtered

(3) Double-click the browser.shell.checkDefaultBrowser preference to switch the value from true to false

Hope it works. Please tell me asap so I make fix your problem as soon as I can!

Kind regards,

Bithiah

It's kind off strange, thats my own PC so i have no idea which one organization is managing this. I've tried, we'll see. I have to wait for a result to the tomorrow to be sure. Thanks for help and i hope it will work.

Nope, still nothing, i dont have problem with it if i turn off option with remember history.

There are two things you could try. 1. Start Firefox in troubleshoot mode. https://support.mozilla.org/pl/kb/firefox-zmiana-jezyka-interfejsu-uzytkownika 2. Create a new profile. https://support.mozilla.org/pl/kb/zarzadzanie-profilami/history
