Firefox Support Forum

Some websites must log in again after reopening Firefox, like www.baidu.com of China. I didn't clear the cookies and histories when I closed the browser, and other sites like Google didn't have this problem. I've tried removing all extensions, that didn't fix the problem. This problem does not occur using other browsers.

This started recently, after I installed the latest upgrade of Firefox and the video downloader. Not happening on Safari or DuckDuckGo. I suspect they have spotted I am using Firefox and are lying about the connection problem. Any suggestions welcome. thanks!

SSIA for the most part. I am running firefox 124.0.1 on my macbook air and, only from certain senders, does the formatting look different from others - the font is different, and I can't highlight or click links. Almost seems like a picture instead of text - I can even click in the general area and it'll copy/paste it in Word like a picture.

Any suggestions?

Hello, I'm specifically looking for help from web developers who understand browser quirks. My AI art website https://enhanceai.art/ Enhance AI looks inconsistent across browsers. Any advice on pinpointing what CSS or elements might be causing the problem?

I am experiencing more and more pages suddenly not working on numerous websites. I am working with an Imac running OS 10.9.5. I am experiencing problems with Firefox, Chrome and Safari and am having to revert to my Microsoft Lap top for a working browser.

Any ideas on this???

Hey all, as of the past few days when I get the prompt to enter my password on Outlook.com (And microsoft.com) and hit 'sign in' the page just reloads and nothing happens. There is no failed login message, the page just reloads like I didn't hit sign in. I have disabled all of my extensions, cleared cookies and cache, ETP... with no luck.

Works fine on Chrome for android...

I'd really like to stay with Firefox so all help seriously appreciated

My API URL is giving me CORS Error in Mozilla Firefox, but in other browser there is no error. I have tried many methods like changing the about:config but it didn't make any difference. Its been days I am facing this issue. Kindly help. Thanks in Advance.

FRONTEND : Angular. BACKEND : Dotnet core API.

Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at <MY WEB API URL>. (Reason: CORS request did not succeed). Status code: (null). Dotnet code for API services.AddCors(o => o.AddPolicy("MyPolicy", addcors =>

           {
               addcors.AllowAnyOrigin()
                   .AllowAnyMethod()
                   .AllowAnyHeader();
           }));

app.UseCors("MyPolicy");

Hello,

I use Firefox stable on both my Mac and my Win 11 PC. On the mac i use the developer edition. The issue I have started about 2-3 weeks ago. Most of the time, playing youtube 4k videos just either freezes and doesn't buffer, or just skips and reloads. It is not a network issue. I've tried playing back the same video with ARC on OSX (which is based on chromium) and with Chome on windows. It works flawlessly so it's not a network issue. I've tried disabling adblocker, all the extensions, nothing. It's either Youtube messing with non google products again or a problem with Firefox itself. I even have Youtube premium and this stuff still happens without adblockers.

Any help would be appreciated.

SHORT STORY:

I have been able to find extension behind errors shown in dev. console (F12 key) like CSP ones (mouse hover over the link near the error on dev. console (F12 key), Console tab, to see moz-extension://somestring and find first characters of the string at page about:debugging#/runtime/this-firefox) But is there any better/easier way to find out web page issue causing extension?

LONG STORY:

Website fails to load (but in a Private window loads OK). F12 key in normal window, Console tab, shows:

SyntaxError: redeclaration of let settings

clicking it, it further show:

abc123-def456-...-...-....:1:1

   <anonymous> blob:moz-extension://8834...

inject resource://gre/modules/ExtensionContent.sys.mjs:581

   AsyncFunctionNext self-hosted:852

when i search for mentioned 8834 (first letters of a long string) at about:debugging#/runtime/this-firefox (i get there clicking settings wheel at about:addons and "Debug addons".) then i find Chameleon extension.

So I try to pause extension in its menu, that not helped, but disabling whole extension in about:addons removed errors, yet page still does not load. 4 remaining CSP errors like:

Content-Security-Policy: The page’s settings blocked the loading of a resource at inline (“script-src”). contentScript.js:160:48951 ...

when I mouse hover over the hyperlink "contentScript.js:160:48951" the browser status bar shows extension address and when i memorize first letters of the address and search it at mentioned about:debugging#/runtime/this-firefox tab, i find: Phantom (cryptocurrency wallet) Metamask (cryptocurrency wallet) Phantom (cryptocurrency wallet) Violentmonkey (provides userscripts support for browsers - I am using it only for https://github.com/Owyn/HandyImage which is disabled currently)

I have tried to didable all these extensions causing removal of a CSP errors, yet page still does not load in normal browsing window (in private does). Normal browsing window shows only one warning/error:

Source map error: Error: NetworkError when attempting to fetch resource. https://firefox-source-docs.mozilla.org/devtools-user/debugger/source_map_errors/ Resource URL: moz-extension://extension address here/browser-polyfill.min.js Source Map URL: browser-polyfill.min.js.map

when i search for the extension address first letters at mentioned page about:debugging#/runtime/this-firefox i find "Textarea Cache", disabling it does not make page load.

After re-enabling disabled extensions and restarting Firefox, page started loading. I suspect (likely wrong) that the python application which is serving local web page in question had exhausted connection limit for the normal browser window/process, but the private browser window process was OK.

What i can do better to discover the causing extension or other cause of failed loading page?

Hi,

This appears to be an ongoing issue with several community support pages now archived, but the problem still persists. This is after applying cor-el's workaround in https://support.mozilla.org/questions/1413716.

OS: MacOS 14.2.1 FF: 122.0

As suggested in the related instructions, I tried with both ^ (just the first datestamp shown consistenly) & * (datestamp appears shortly in first post, then disappears very quickly <1sec), with results shown respectiively.

Is this a Mozilla issue or FB trying to be funny...? If the former can we have a bug ref that can be followed. All I see from the community posts are questions being archived once the cor-el workaround has been added. This isnt a lot of use for those still effected...

We need to configure our firefox settings on mac to use with a zebra printer & lightspeed label printing. We have worked with zebra support and lightspeed support, and the firefox version 122.0 does not let us "save" the about:config settings needed to print. We put them in, but it reverts back and doesnt let us save the steps defined in this section of the article:

Since your last update I can no longer view my credit card statements, it downloads a pdf file. If I go to download the pdf instead I receive four pdf files downloaded. The edge and brave browsers don't do this.

Firefox: 101.0.1 (64-bit) MacOS Monterey M1Pro MacBook Pro 14"

When I am watching a video from inside firefox, I am unable to exit full screen mode by using the esc key. It was working before and after updating firefox it suddenly stopped.

Please assist

One part of the article I read says the connection issue is due to HTTP, another part of the Article says it is Googles fault due to their HSTS security policy. I have to say Poppycock. I can successfully login to my Gmail on my tablet I just cannot connect to it with my laptop. Firefox itself is refusing to allow the connection. Unfortunately it happens more often than you'd expect. I am in no way or by any means capable of computer repair, but I seem to enjoy tormenting myself with constantly taking apart and rebuildingthis laptop, Took me almost 3 months to finally find out how to stop Firefox address URL bar from highjacking the search bar with that really annoying awesomebar in about:config. But something just seems wrong with the browser on the laptop not being able to connect, but there is no issue with the tablet.

Thank you for any advice or solution that could help me with this. Ive thought about the firefox refresh reset option instead of uninstall reinstall, but if there is a better solution

LasVegasRich@gmail.com Windows 7 Pro PC. Mozilla Firefox. DuckDuckGo search engine. ExpressVPN.

When I try to Forward a gmail post with either a CC: or BCC: Command, my Contacts List doesn't load. Initially, I see an "X" in the right-hand corner

followed in less than a second, by another "X" superimposed over the first one. What might be causing this? I (reluctantly) loaded Google Chrome and made it

my default browser, after which, my Gmail worked properly. Assuming, then, that the problem is being caused by the Firefox connection to the Google servers,

I uninstalled Chrome with the Revo Uninstaller Pro and reviewed the Firefox settings.

My Firefox Extensions are thus: AdBlocker for YouTube, Disable HTML5 Autoplay, DuckDuckGo Maps, DuckDuckGo Privacy Essentials, Enhancer for YouTube,

ExpressVPN, HTTPS Everywhere, LastPass, Malwarebytes, Online PDF Editor, Pinned Google Calendar, Return YouTube Dislike, SponsorBlock for YouTube, Video

DownloadHelper, and YouTube High Definition.

Hi all. I am having a strange issue with Discord. I can get notification sounds and all other media plays fine there. But whenever I try to "speak comment" or set the settings to always speak comments, nothing happens. The tab shows "playing", but no audio comes out, and nothing shows coming through on the mixer.

Chrome does speak as expected. A different computer, same version of Firefox also does speak as expected (in a different voice though). So that narrows it down to something in this particular copy of Firefox that is causing the problem. Plugins, settings and extensions on the two computers look the same. Also tried a different audio interface. If anyone has any ideas, please let me know!

Specs: Windows 10, Firefox 91.0 32 bit (both computers)
