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

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?

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.

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

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,

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

Firefox seems to forget edits made to text boxes. I was reading a large pdf and adding notes to previously made text boxes. I thought I must be going crazy as I saw there was no notes I thought I had already made multiple times so I tested it. I edited a text box, scrolled a bit and continued browsing on another monitor. Checked in a minute and boom edit gone. If anyone has a solution I'd appreciate it as I have been using Firefox PDF editor for a bit and quite liked it until now.

I run Firefox Developer Edition.

I recently added some lines to my hosts file (C:\Windows\System32\drivers\etc\hosts). Despite these additions, Firefox ignored the hosts file and loaded the pages I had blocked just fine. So I tried a multitude of options like disabling "Enable DNS over HTTPS" and eventually I got to work and the hosts file was respected.

So after thinking about it for awhile, I actually DO want Firefox to ignore the hosts file like it did before I made the change. I reverted the "Enable DNS over HTTPS" setting to its default of enabled, and I've tried everything else I can think of, but I just can't get it to work.

How can I configure Firefox to ignore the system HOSTS file and load blocked pages anyway?

Could really use some help.

I have a problem on YouTube where videos are too bright, but when i click for example to save that video to watch later it has normally saturated colors. And I'm using windows. On photo example1 video is too bright, but on example2 it is normal. thanks for help

Hi

This is on Ubuntu. I installed Firefox Developer edition to /opt/firefox and made a .desktop file I put in ~/.local/share/applications and this was working well. I added it to favourites so it appeared on the dock, and added some customizations.

But at some point Firefox started to create its own .desktop file at launch when it prompts to be default browser and you say yes, called stuff like "userapp-Firefox Developer Edition-N8YCQ1.desktop". These files fill up ~/.local/share/applications and break my existing file by making a second Firefox icon on the dock so I cannot click the first one. Also my own custom file had Desktop Actions so I could right-click the icon to open a new window or new private window, but the generated ones are barebones.

Every time I delete the "userapp" file, a new one is made the next time I open Firefox (which has now forgotten it is default browser) and the issue is back. Is there an option to disable this behaviour?

Thanks for your help

Trying to reinstall a working module that I deleted, but now it only displays the title. And none of the code works.

Why is part of the code greyed out in Firefox developers.

Why does Firefox scrolling bounce across posts in Facebook. As you scroll through posts suddenly Firefox will skip 2-6 posts ahead? It does not do this in Chrome!

Hello: I just install FF 106, and was given a choice of several different browser colors. I did choose one, but really do not like it.HOE can i return the browser?? looked through all settings could not find a way to reverse back. Think i will be more careful next time:) thanks very much Allen

Firefox prioritizes IPv6 (even on a network with internet-accessible fd00:: address, which contradicts my currently set up prefix policies) over IPv4. Now the problem is that my IPv6 address is a tunnelbroker.net one, and while I still want to be able to access the IPv6 internet, I don't want a tunneled connection to be my default. And I don't want to disable IPv6 completely. Is there a way to force Firefox to prioritize IPv4 over IPv6?

Note: the first time when connecting to a website, the browser connects via IPv4 (like the prefix policies are supposed to work), but then it remembers that the website is accessible via IPv6, saves it into the content-prefs.sqlite file (removing the said file makes the connection fall back to IPv4 first again) and connects via IPv6 again. Is there a way to make Firefox NOT remember that in content-prefs.sqlite and still connect abiding the prefix policies?

Using Firefox Dev Edition 103.0b9 on Windows 11 x64

Hi,

Its about time you looked at your Mic cam Cam settings

I'm getting older, they should be set as on as Default, and switched to off if required

This is a massive issue to a great part of the community I don't use Firefox as I used to, as so many of my clients are also moving away, ( Gone to different platforms to Edge and Chrome) I'm sure this can be easily fixed.

My Firefox has got inconsistently large font size in some UI, namely on the homepage (text elements with style "font: caption") and texts in the Update Firefox notice box (which I don't know how to reproduce within a resonable time and effort). It just happened after a ordinary restart of Firefox: no updates etc. I tried updating Firefox after that but to no avail. How can I fix it?

Hey folks, I use the firefox developer edition and I downloaded a zip file in it's private and when the download was complete I closed the window and open the download folder but the file was not there I haven't change the downloads folder location
