Firefox 技術支援討論區

I have been using Firefox 52.9.0, and I know it is outdated but it still synced until a few days ago at least. Then the other day I updated my password to strengthen security. After that, I am unable to sync anymore. Is there a way to fix it? I need to continue to use Firefox 52.9.0. Please note that I do not need to be told about security issues as I am aware of them well enough.

I get the following message when I try to make Firefox to sync:

> Blocked by Content Security Policy

> This page has a content security policy that prevents it from being loaded in this way.

> Firefox prevented this page from loading in this way because the page has a content security policy > that disallows it.

Thank you.

A few days ago I was told via message that firefox will stop support for windows 10. I ungraded my system to windows 11 and downloaded the appropriate version of firefox. Now I'm getting the same message again. Please help. I like firefox but being told continuously that it's no longer supported even though I've upgraded my system to one that is supported is a pain.

all of a sudden , I need to update fire fox,have reinstalled it. It won't run the download, will not connect to sites I have used in the past.They want a newer version of fire fox,I have windows xp.

I want to log in Tanki online games but not working...asking me to search Advanced panel. I dont know what is that...have HP 620 with Windows XP inside...thanks anyway...(:-())

I'm trying to sync from Windows XP to Windows 8.1. When I sign in on XP I get a completely blank page and a few buttons. When I click on 'Reconnect to sync' I get the message "Blocked by Content Security Policy. This page has a content security policy that prevents it from being loaded in this way. Firefox prevented this page from loading in this way because the page has a content security policy that disallows it". What other way is acceptable?

W10 Pro (sys info & TS info are below) I run both w/32-bit 91.4.1 esr & 64-bit 95.0.2 on the same machine. I tried to manually upgrade the esr to 64-bit but am told 'unable - system incompatible' and get the W XP & Vista support ended at 52.9...I'm running 32-bit 91.4 AND 64-bit . Help me understand if/what is incompatible so I can manually push my esr to 64-bit. Getting to 64-bit from 32 (per help page) says to just download and run the 64-bit ESR setup.exe. That fails...same issue...incompatible. FF setup thinks my OS isn't W10 Pro....so does the ESR FF 'application menu'...and the TS info. My ESR is set as the default browser app. AND I don't have any (known) issue with the 64-bit 95.0.2 Advice? Do I need to uninstall the 32-bit esr strangely I am already running 91.4.1 32-bit esr...says HELP/about.??? I'd like to know what esr is actually running...I presume 32-bit. Thx, wgk
