I recently switched from chrome to firefox and ever since i cannot open any outgoing links on tumblr. no matter where they're going i get an error message (this is german, sorry):

Fehler: Gesicherte Verbindung fehlgeschlagen Beim Verbinden mit t.umblr.com trat ein Fehler auf. PR_END_OF_FILE_ERROR Die Website kann nicht angezeigt werden, da die Authentizität der erhaltenen Daten nicht verifiziert werden konnte. Kontaktieren Sie bitte den Inhaber der Website, um ihn über dieses Problem zu informieren.

this happens on my windows 10 pc, my macbook air and my android phone, so i think the problem is with firefox (i guess with my account, since i've synced them) and not the device.

the links don't work wherever they go, be it youtube or wikipedia or anything else, not just unsafe sites. this only happens with outgoing tumblr links as far as i know. i think it must be something about the tumblr redirect part because it always happens with those.

i have tried running in safe mode, clearing cache and cookies, but none of those made any difference.

Are that possibly links to insecure HTTP websites that do not have a certificate installed ?

It's ALL links and i doubt they all are insecure sites. I can't reach sites that i normally don't have any problems with. for example here's a link to a youtube-video i embedded in my own post:

this is the direct youtube-link: https://www.youtube.com/watch?v=XAc2iFVQbFU this i can open no problem

this is the link when i click it on tumblr: https://t.umblr.com/redirect?z=https%3A%2F%2Fwww.youtube.com%2Fwatch%3Fv%3DXAc2iFVQbFU&t=YTM1NTdjZjYyZjFhZDUzNTk4MjRhYWIxOGJlY2NlN2JhZDY2Nzc1Ziw1NGNiYTI2YjcyMzQwY2YxM2U5MGI1YjY0YmYyMWU0NThlZjRlZTJk&ts=1599123951 this will give me the error message

I have no problems whatsoever reaching youtube in any other way, only from a tublr link.

No problems here, with both links I get the YouTube website.

Try to disable IPv6 (check for other possible causes as well).


You can remove all data stored in Firefox for a specific domain via "Forget About This Site" in the right-click context menu of an history entry ("History -> Show All History" or "View -> Sidebar -> History").

Using "Forget About This Site" will remove all data stored in Firefox for this domain like history and cookies and passwords and exceptions and cache, so be cautious. If you have a password or other data for that domain that you do not want to lose then make sure to backup this data or make a note.

You can't recover from this 'forget' unless you have a backup of involved files.

If you revisit a 'forgotten' website then data for that website will be saved once again.

thanks for the suggestions!

I tried disabling the IPv6, that didn't change anything (i returned it to false again afterwards, though) I also tried some other suggetions from that link and none of them worked either (removing and readding firefox from the firewall allowed-list, DNS Prefetching (was already set to 'true') and cleared the cokies and cache again)

I also tried forgetting the website, which also didn't seem to change anything.

Sorry, those didn't work, but thanks anyway!
