What start page are you talking about? And screenshot of the issue.

hi its a pop up to use startpage as my browser

Hi Martin, where do you see the message? For example:

• a new tab opens promoting Startpage
• your home page changed to Startpage
• a desktop notification opens outside of Firefox at startup, or after your home page loads, or at some other time
• a notification drops from the toolbar about installing something from Startpage
• some other location

Extension Check

After a Refresh, normally all your add-ons are removed. But then, after signing in to your Mozilla account, Sync could bring them back, so it's worth a quick check whether you might have one related to that site. You can view, disable, and often remove unwanted or unknown extensions on the Add-ons page. Either:

• click the Extensions button (puzzle piece) on the toolbar > Manage Extensions
• Ctrl+Shift+a (Mac: Command+Shift+a)
• "3-bar" menu button (or Tools menu) > Add-ons
• type or paste about:addons in the address bar and press Enter/Return

In the left column of the Add-ons page, click Extensions. On the right side, find the "Manage Your Extensions" heading.

If there is at least one extension before the next heading -- "Recommended Extensions" -- please continue:

Then cast a critical eye over the list below that heading. Any extensions Firefox installs for built-in features are hidden from this page, so everything listed here is your choice (and your responsibility) to manage. Do you see any extensions related to searching or privacy? Anything suspicious or that you just do not remember installing or why? If in doubt, disable (or remove). For your privacy and security, don't let mystery programs linger here.

Any improvement?

Note: Sometimes extensions can frustrate access to this page. In that case, first restart Firefox in its Troubleshot Mode and then try again. See: Diagnose Firefox issues using Troubleshoot Mode -- Open, not Refresh.

Hmm I wonder if these are web push notifications from a site you have allowed to send you notifications?. If so then you can revoke those sites from sending you notifications.
