Firefox Community Forum

Content Security policy blocks essential scripts no matter what I do.

It's new Firefox installation, Troubleshoot mode, Enhanced tracking disabled, I'm not on VPN, can log into X.com in another browser just fine.

It's the reason #1 I don't use Firefox. I thought the issue would be fixed but it has been like this for long time.

Yet whatever I do, whatever I turn off this pops up:

Content-Security-Policy: The page’s settings blocked the loading of a resource (default-src) at https://abs.twimg.com/responsive-web/client-web/bundle.Conversation.721fc4aa.js because it violates the following directive: “default-src 'self'”

The screenshot is from Zen, but it uses Firefox and the issue is the same in Firefox.

I'm trying to use the built in VPN. I'm signed in but it just keeps returning me to the same page. The VPN icon doesn't have a green tick - it keeps the little black cross next to it. What am I doing wrong?

MacOS, M2 2023, fully up to date firefox.

Sometimes I'm using firefox and it just stops loading pages, internet is fine. Other browsers work. I look at my activity monitor and nearly 100% of my 32GB of ram is being consumed by various firefox processes. A lot of those processes seem to be associated with youtube. This problem usually, but not always, is resolved by restarting firefox. But this shouldn't be happening. I have a lot of tabs open sometimes, but it's not that excessive. And most certainly not 32GB worth and preventing my computer from doing a google search.

If there's a debugging thing I can do to post system logs, let me know and I'll post them next time this happens. I'll be away from my computer until early July, so around that time.

Hello - downloads have started on my Mac desktop - do not know what they are - and they seem to be ever 4 hours. I have attached a screenshot of my download file. Any advice would be appreciated.

Thank you.

I have upgraded to a Macbook pro 2023 M2 Tahoe, and reinstalled firefox. When I open it, the search bar & my tabs all show as expected, but then disappear, can't find them. I have to close and open again to get back them back. I have googled this, tried some things (about:config - made sure "browser.fullscreen.auto hide" is set to false). I do not have a setting "always show toolbar in full screen" as suggested by google search. This shouldn't be that hard! Any thoughts? thanks!

When browsing between two screen, all my saved Firefox tabs disappeared. I have restarted my computer but they do not reload. I really need them (and have not accessed some of them in several weeks so it will be very hard to recover from history.) WHY did they go away and I do I restore them?

Firefox suddenly stopped autofill for one of my credit card websites. Went to settings and everything seems to be in place. after manual log in FFasked to save info and I checked 'Save', but still no go. It just added new(additional) login info to my list of passwords.

I'm on the latest firefox version 151.0.4 and having issues with the built in free VPN. It's showing up in the settings but I don't have the icon in the tool bar to adjust it or do anything. It's definitely enabled because it shows the settings and 50gb remaining of data. I've tried doing the about:config setting for enabling protection as well but that was already set to true. I toggled that and restarted my browser and firefox but neither worked.

When I hit enter after clicking youtube.com , my screen turns into grey spots where the videos should show and no other written info on screen. What is going on??? I can go in when Safari or chrome.

I had an unusual system crash, and when I restarted Firefox, the History > Restore Previous Session feature was grayed out. Due to the nature of my work, I had a large quantity of tabs open at the time of the crash (please don't judge). I then backed up the contents of the \Library\Application Support\Firefox\Profiles\[session].default\sessionstore-backups\ folder, but unfortunately not the full Profiles folder content. The file recovery.baklz4 does seem to contain my open session info (I can see a recent link in it). Based on web advice, I then tried restarting Firefox, but that didn't solve my issue. I also tried copying in sessionstore-backups files, without success. I then tried the "Session History Scrounger" web application to try and recover links from the contents of recovery.baklz4 because that worked for me in a prior crash years ago, but it doesn't seem to work properly anymore (it only retrieved 4 web pages). Appreciate any guidance as to how I can use my backed up sessionstore-backup files to re-enable Restore Previous Session, or alternatively to scrounge the links that were open at the time of the crash. Greatly appreciate your help! (Please do not suggest using "Show All History"... I have no plans to sort through a dump truck of rice with a pair of tweezers.)

no matter what website when i put on a video it fades between normal and black constantly i dont know if its my computer im not very good at tech it doesnt happen and never happened on google

It seems that after a recent Firefox version update (perhaps to 151.0.3), the "Clear cookies and site data" option is disabled for any container tab. This is really annoying as I like to use this feature often.

I'm unable to type in "Notes" for specific transactions on my Credit Union's web site. It used to work fine until several months ago. The entire Credit Union web site won't allow me to add info or type in a box provided by them for such purposes as it did. I have to use the Safari browser (which I hate using) to do so. HELP!!

Good morning. I'm trying to configure my shortcuts on my home screen. Specifically, I want the shortcut button's icon to display the website's favicon, rather than just the default circle with a letter. I set the custom icon field for the button (as an example) to:

https://www.notationtraining.com/favicon.ico

I have verified that this favicon exists and I can load it into a separate firefox tab. However, it won't display in the shortcut button. I've tried restarting and trashing some caches without success.

Where am I going wrong? I'm on FF 151.0.4 for Mac OSX 26.4. Thanks, Eric
