Firefox Support Forum

Hello guys, so in the past 2-3 days i started facing Cross-Origin Request Blocked for a lot of websites lets take chatgpt for example, if i visit it i get:

Content-Security-Policy warnings 2 Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://cdn.oaistatic.com/_next/static/chunks/sso.74deac81d652476b.js?dpl=f90a861ef09abad575887be5d613ce15a4fdb6d9. (Reason: CORS request did not succeed). Status code: (null). The resource from “https://cdn.oaistatic.com/_next/static/chunks/sso.74deac81d652476b.js?dpl=f90a861ef09abad575887be5d613ce15a4fdb6d9” was blocked due to MIME type (“text/plain”) mismatch (X-Content-Type-Options: nosniff).

and its getting so annoying that its blocking a lot of websites, i tried chromium it works fine and works awesomely no cors no problems. I even tried to disable the firefox protection, dns over https on/off, change my main dns upstream, installed firefox developer, compete uninstall/reinstall, cache clear from installers and from firefox it self nothing is working. I will provide firefox developer edition troubleshooting information but keep in mind it doesnt work on both firefox normal and developer

Please any help would be appreciate it.

Firefox v124.0.2-1

Long story short: windows update sneaked a restart under my nose caused me to lose all my previous session.

I'm attempting to recover the previous session.

I have backed up the unmodified session profile folder. But this profile folder was modified by the restart process obviously, as windows gave firefox "normal shutdown" command. How do I know that? The next time I opened it up, it's "brand new" without the "restore session" interface.

So my idea is to figure out if firefox keeps a track record of previous sessions EVEN IF THE SHUTDOWN WAS PROPER.

If it does, well I'll have to figure out a way to "trick" firefox to restore it. If it doesn't, well I'll have to manually restore it by sifting through the history.

I repeat, the key here is for me to find out whether or not firefox always keep a record of previous session somewhere.

So my question is, does it? Or does it purge all the previous session clean as long as the shutdown was deemed "correct"?

I am using Ubuntu 23.10.1 with KDE Plasma desktop environment. Since recently I've been experiencing the following problem with Firfox document viewer: after a period of inactivity, PDFs become unreadable, and seem to cumulate everything that was displayed on screen (see screenshot). Ctrl + F5 does not help, and neither does closing the window and opening a new one with a link to the file. KDE Document Viewer displays the same file correctly.

Kubuntu 22.10 FF Dev Ed 110.0b9

Trying to use throttling (eg. Regular 3G) in Network Tab.

In developers edition, any Throttling setting (other than "no throttling") never loads any website. Just white screen.

Creating a new profile and not making any changes to it, did not change anything.

I am using Ubuntu Firefox 110.0 (64-bit) on Ubuntu 22.04 x86_64. I am unable to play contents on Disney+, Amazon Prime Video Netflix and such. I was streaming fine until a few months ago. I have checked my settings and they are all properly set. At the time I am writing this report, the Widevine Content Decryption Module is at Version 4.10.2557.0, updated to its latest release. Obviously DRM content is enabled in settings. Changing the useragent did not solve the problem. I have seen this problem reported before for MacOs users but I could not find anything for linux users. Am I the only one having this problem? I hope someone can help. Thanks

Hi Team,

After updated to latest version of Firefox - 118, we facing with this issue: Dynamics 365 App required sign in again and again to use. We need to click on sign in at least 3 times, but no need to provide the credential.

Checking the network log, seeing this: error_description "AADSTS700084: The refresh token was issued to a single page app (SPA), and therefore has a fixed, limited lifetime of 1.00:00:00, which cannot be extended. It is now expired and a new sign in request must be sent by the SPA to the sign in page. The token was issued on 2023-10-09T07:45:27.2163809Z.\r\nTrace ID: 07fa536f-3cd8-4f91-9950-66dc69928b00\r\nCorrelation ID: 594b0d6f-0dab-48e4-900d-f92b8a382eba\r\nTimestamp: 2023-10-11 08:46:36Z"

On some sites like youtube, crunchryroll, and other sites usually where it's main purpose is to play videos my sound plays fine. However, on other sites like osu's website, chess.com, duolingo, and others, there's no sound at all. I've tried refreshing, restarting, running in safe mode, and even reinstalling the browser but none of it has worked. My tabs are also not muted. Does anyone know how to fix this?

MacOS FF dev edition 102: I have a folder in my bookmarks toolbar, and I frequently open all of them in tabs. But that option is missing from the context menu on the folder. It is there at the bottom of the folder if I click to open the folder, but this is silly. There is an "open all bookmarks" context menu option on the folder, but that opens all the bookmarks in the toolbar, not in that one folder. why is this?

I'm on Firefox Developer Edition 119.0b9 (32-bit) and Windows 11 Pro 22H2 but I've been experiencing this problem a lot longer ago even before upgrading to Windows 11. The first thing I open in my computer is Firefox, it gets the window itself quickly but the page stays blank with the gray loading dot going right and left for nearly 10 minutes before the page loads and Firefox works normally. I don't experience any issues while browsing the internet after that long loading but it's really annoying especially when I'm in a hurry and I don't have 10 minutes to stare at a blank page.

Tried restoring through menu several different bookmark dates, different size/link amounts, loops and never completes.

External backup in future, best way???

Other issue is copying link from a Google tab, to a Facebook tab, have about a 10-20-second delay (a block) before I can access the Facebook tab to paste the link - This worked fine until about a month ago. Opera work fine.

Should I forced FF to complete SANDBOX mode to restore functionality??? Switch to DEVELOPER version??? Try to GO-BACK MUCH OLDER VERSION???

Thanks,

Tim

Hi, lots of good support to how to sync. No support for how to view synced tabs on an iMac. I can see the synced tabs and open them on my iPad and iPhone. Thanks for your assistance.

I have been seaching for the solution for the whole day, and i found the closest one. It Does remove tabs, windows buttoms, but the background bar still remains, and i dont need it this way. So thats the code i used to make it >>>>>

1. main-window[tabsintitlebar="true"]:not([extradragspace="true"]) #TabsToolbar .titlebar-spacer {

       border-inline-end: none;

}

1. main-window:not([extradragspace="true"]) #TabsToolbar > .toolbar-items {

 opacity: 0;
 pointer-events: none;

} /* This makes the bar shorter vertically but removes the 3 window buttons */

1. main-window #TabsToolbar {

 visibility: collapse !important;

} /* For full screen mode */

1. TabsToolbar[inFullscreen]{

 display: none !important; 

}

On the screenshot you can see what remains on tabs' bar place I need my browser to end just above the URL string, so there wont be empty space in the top of the monitor. Can you help me find solution for this problem, please?

Every time I work on the local environment a lot of my extensions go crazy on localhost, throwing enormous amount of errors. This makes console barely readable. Is there a way to disable messages thrown by extensions in the developer tools of Firefox Developer Edition?

Similar to this in Chrome with "Selected context only": https://superuser.com/a/1346827

Thanks.

why do my add-ons keep getting disabled?

ff keeps disabling add-ons that i have used for years and even keep a v. 5 to use the older add-ons and use the latest ff developer to use w/ more modern websites. ff even disables add-ons that worked perfectly well in ff developer and does not even give me the opportunity to re-enable them like i could before.

is there any way to force my old version to let ME decide what i want disabled/enabled?

If I search for something in the address bar, Firefox will endlessly load. I need to click the address bar and hit enter to search again which will instantly load what I'm looking for. Same thing happens if I highlight a text and click search with google. URLs seem to work fine.

The 10/18/2022 update changed the theme and color settings for my browser. It is practically unusable. Attempts to use other themes do not solve the problem. Every web page I have used since the update is affected. Screen clip attached. Besides killing my productivity today, this change has made FF unusable! How Do I get this Reset to Prior State?

PS: Just now, I try to click the box for "Email me when someone answers the thread" and it will not mark the box.

Hi there,

I have just set up a new Wordpress site, which is currently in mantenance mode. For some reason, i think becuase I was using FF Develoer Edition for the domain nam DNS set up, I just cannot access the site. The maintanance page shows, but is broken, and the Wordpress admin page is inaccessible, giving the "The page isn’t redirecting properly" error.

I can access the site just fine in another browser, including regular Firefox, on my computer, or any other. It's just tied to this one FF Dev Edition. I have tried all suggested fixes regarding clearing Cookies & Cache, deleting all history, setting up custom cookie tracking, using "always use private browsing mode", to no avail. I've even deleted & reinstalled FFDE. I'm on Mac & have also used Terminal to purge my DNS cache. I just can't access this URL:

https://www.advicerooms.co.uk/wp-admin

As mentioned, this works just fine in any other browser.

Any ideas? FFDE is my web developing browser of choice & I need to start working on this site, but will have to drop FFDE for another browser now if I can't sort this.

Hope someone can help!

Many thanks in advance

Mat
