Firefox Community Forum

We've noticed that in Firefox 112.0 (maybe in 111.0? haven't tested yet...) when a `fetch` request with an `Authorization` header gets a `302` (or `307`, and probably any other redirect response code) and `redirect` is set to `follow`, the second request is made _without_ an `Authorization` header, which breaks our website.

In 110.0 this isn't an issue, and no warning is logged to tell us it's about to change.

I'm guessing this is a security change - could someone point me at the discussion that led to it being made? My feeling is that if the redirect is to the same origin as the original request sending the same `Authorization` header should be secure enough.

I'm wondering what the right mitigation is; we could follow redirects manually of course, but it's a pain.

Hi, I'm developing a webapp that's designed for print. It uses a "pinterest style" layout to have a column grid of objects with variable heights, and the print styles avoid breaking these items over the page barrier. (In fact, there are two grids on the page, one after the other). The website looks and works fine on screen, and both screen and print work great on Chromium browsers. But on Firefox, using ctrl+P or developer tools' print view causes the page to hang and the tab to ultimately crash.

I know it has something to do with handling the grid layout CSS as the print preview worked fine until I made the change from a traditional row-grid to a column-grid.

The site creates a variable amount of content based on user options at the top of the page. If the content generated is quite small (avoiding a page break?), the print preview works fine. In the link below, I've included some GET variables to guarantee a long amount of content to reliably reproduce the issue.

The site in question.

After updating Firefox to Firefox 125.0.3, Google ReCaptcha2 stopped working on my sites (I use the invisible version). Then I checked the version from the official website and it doesn’t work either.

I read about self = this on stackoverflow, but this also does not help on my sites. After clicking, nothing happens, and there is an error in the console.

Has anyone encountered this?

The same behavior here https://www.google.com/recaptcha/api2/demo, an error is displayed and loading... loading... loading.

Error in console is like: UncaughtObject { stack: "z<@https://www.gstatic.com/recaptcha/releases/WQcDpAcHn0sjM6ZiVkU8JwNH/recaptcha__ru.js:470:201\nH<@https://www.gstatic.com/recaptcha/releases/WQcDpAcHn0sjM6ZiVkU8JwNH/recaptcha__ru.js:258:...

from https://www.gstatic.com/recaptcha/releases/WQcDpAcHn0sjM6ZiVkU8JwNH/recaptcha__ru.js line 448:1

Tested on absolutely clean Firefox without plugins, with security turned off, without cookies and account.

When i start browsing from Holland IP via VPN the problem are solving. In Chrome, Edge ReCaptcha2 working fine.

When I go to Amazon.com in Firefox, the URL is changed to this: https://www.amazon.com/?smdm-noredirect=true I cannot change it back - it continues to apply ?smdm-noredirect=true

When I try to log in via that path, I get this message:

Looking for Something? We're sorry. The Web address you entered is not a functioning page on our site Go to Amazon.com's Home Page

This does not happen on Chrome.

Every time I try to sign into my Google account (including related sites like YouTube), I'm rerouted to the Microsoft sign in page for my old university, and can't log in. This only happens on Firefox, if I switch to another browser then there's no problem.

So far I've tried:

• Deleting all of my history including my cache and cookies.
• Once I'm at the site I'm rerouted to, going into History, right-clicking on the url, and clicking "Forget this site."

Neither have worked. Any suggestions appreciated!

Hello:

I must use the magnifier that came with Windows or I cannot read the screen. All was fine until Firefox updated. Now, when I try to use the magnifier, Firefox and all the sites I am using freeze. The entire screen fades out, and an hour glass shows up. But nothing happens after that. I have to go to the task manager and close Firefox, then start it up again.

I checked for Windows updates and everything is current. I am using Windows 10.

How can I fix this?

On version 89 while on Google Images, I can no longer click the image thumbnail to bring up the side menu on the right with the full size image.

It previously worked fine. I tried troubleshoot mode with all extensions removed and same issue. I tried on chrome/edge and later versions of firefox above 100 and it works as well.

My guess is there was some recent change on googles end that broke this on the older version. 89 supports webp so im not sure its that.

I like this version and would like to exhaust all possible fixes before defaulting to updating.

Hello, everyone.

4-5 days ago, I've noticed weird YouTube playlist behavior. When I start playlist and switch to a different tab (or minimize browser) first video will play normally and it will autoplay the next one. But after finishing playing 2d video (3d in some cases) video will just stop at the end of playbar and not autoplay the next one in playlist. Playlist for example: https://www.youtube.com/watch?v=giUY_pEKTzY&list=OLAK5uy_nKmglmCCbx14WeFyH8e7YGYcL5skYwnp0&index=1

It's rather easy to replicate, I can record desktop video if needed.

Expected behavior: I can start YouTube playlist playing and switch to a different tab or minimize browser and playlist will only stop after playing last video in said playlist (unless "Loop playlist" option is enabled).

What I've tried to do so far: 1) Googling: I only was able to find old thread and the culprit was extension: https://support.mozilla.org/en-US/questions/952608 2) Disabling Extensions and confirming issue in Troubleshoot Mode: Did not help 3) Clear cache & cookies for YouTube: Did not help 4) "Allow Audio and Video" autoplay for YouTube: Did not help 5) Confirming issue in another browser: Works as intended in Opera 6) Checking about:config: I'm not that savvy with Firefox config to understand what may cause an issue. Tried to change media.block-autoplay-until-in-foreground to False. Did not help, rolled it back to True.

What I have noticed: 1) Firefox recent update: 118.0.2 October 10, 2023: Correlates when I started experiencing this issue. 2) YouTube playlists plays next video continuously just fine if I don't minimize browser or switch to a different tab. 3) There is a Firefox extension that does exactly what I don't want in my experience: https://addons.mozilla.org/en-US/firefox/addon/no-playlist-autoplay-for-yt/ I installed it just to check. And yes, it does what expected and it is similar to what I'm experiencing. Although it stops playlist after finishing first video, my issues go into the affect after playing first video. (Deleted it after testing)

Before posting I've tried a few different things and here where things gets extremely weird: 1) It works just fine in Firefox if I log out from my YouTube account: (Incognito/Main tab) Do not work if I'm logged in, even in Incognito. However... 2) It works just fine in Opera if I'm logged in my YouTube account. 3) It works just fine if I open playlist in mini-player. (Current workaround)

After all that weirdness I attempted to Clear cache & cookies for YouTube and it did not help once again.

P.S. Yes, I use YouTube as a music player. :)

Recently I came to one site that:

• works on Android version of FF in modile (defailt) mode;
• breaks on Android version of FF in desktop mode;
• breaks on Desktop version of FF in default mode;
• breaks on Desktop version of FF in responsive desidn mode (in all available "devices").

So my question is: is it possible to emulate mobile (default) mode of Android version in Desktop version of FF?

Why are google sites (Youtube, Gmail and Search) getting disconnected when all other sites are still connected to the Net? This has been happening since November 2021.

When that happens I close the FF and then immediately open it. Now the google sites work properly.

Never had that problem with other sites.....never!

Why the hell is this happening? Is FF responsible or Google?

So what is the solution?

Using my PC, I am clicking on this URL: https://schoolgateway.westminster.org.uk/?page_id=7. Firefox responds with "The requested service is temporarily unavailable. It is either overloaded or under maintenance. Please try later." Every time. Using Firefox for Android on my phone: same result. I have tried Troubleshoot Mode on my PC: same result. And yet Safari, Chrome, Edge and Brave all load the web page correctly with no error message.

What am I doing wrong?

Outlook.com email service has stopped responding to clicks on "Inbox". First attempt opens the Inbox, all other clicks to go back to the "Inbox" do not work. The only way to go back to the "Inbox" is to use the back arrow in the browser, or click on "Sent"(or another file)...then click on "Inbox". The cycle continues. Been like this since I updated to 110.0.1 (64bit)

Hello everyone,

I need help because on Firefox ESR that runs on Debian some css appears really too big. In this example I will show the difference between Firefox and Chrome. If I open this popup from Firefox it appears full width. In Chrome it appears correct. Also I noticed some Icons rendering incorrect.

How can I achieve this? Thannks

This was one of our primary suppliers for technology. Contacted them they just said "suck it up, princess".

Recently AWS started doing "human verification" on all VPN traffic to websites they host on their CDN(s). This results in all our Windows 10 PCs running Firefox ESR 102.13.0 going into an endless "Human verification" loop, never able to access the website.

On the Windows 2012 R2 server we have access to the above website works. We see "human verification" for a second or two and then the website is displayed.

So, copied my profile from a Windows 10 PC that doesn't work to the server and it works.

I've tried with tracking protection off. Turned off all adblockers, run in safe mode with all addons disabled, cleared my cache, deleted all cookies Created a new profile and still no go. Turned off Windows firewall, moved hosts file out of the way. Still no go. Also deleted prefs.js to run firefox as completely vanilla without any changed preferences.

I'm not inclined to install malware, so chrome based browsers are not an option. They are actually blocked so I couldn't install them even if I wanted to.

All PCs are on 21H2 3208. Upgrading is not an option at this time. PCs will be upgraded mid-late 2024.

All PCs are required to be connected to VPN at all times as we work from home. Being on call late into the night also means we can't just disconnect. We use NordVPN. Yes I know there is a lot of paranoia about VPNs being the source of all online crime. I just think that's an over-generalization. A convenient excuse.

https://www.scorptec.com.au did a similar thing earlier this year, but at least with them we get a captcha and can get to their site.

Could this be a browser issue, or is this more likely to be a Windows 10 issue? Also updated Windows 10 to latest patch each month and it's been the same for three months.

I am using Firefox with the uBlock Origin and Cookie AutoDelete extensions enabled. When I try and load Gmail or any other Google site, I get a blank page and nothing loads at all. This only occurs when my VPN is on (I use Private Internet Access). However, even with the VPN on, Chrome will still load those sites. Disabling the VPN means that the sites load normally.

My guess is it might be some sort of privacy setting in Firefox, but I don't understand what it could be. The only thing that breaks/fixes the sites is connecting and disconnecting the VPN, irrespective of which country I try and connect from.

Hello,

For several weeks now I've been experiencing issues with accessing google sites. YouTube videos will constantly display the "Connect to the internet. You're offline. Check your connection." error page. Additionally gmail and google drive will constantly give the "OOPs" error message. Sometime the page will load w constant refreshes but this is not ideal.

I've done the following:

Clear history/cookies Opening in troubleshoot mode Disable hardware acceleration Refresh/Reinstall

Have even tried the following articles: https://support.mozilla.org/en-US/questions/1377868 https://support.mozilla.org/en-US/questions/1376015

Still getting the same results. Not having any issues with edge/chrome. Does anyone have anything else that could be done?

Firefox Browser 102.0.1 (64 bit) Windows 10 OS

I've been having an issue for a while now where the cloudflare challenges that ask you to click the check mark to "verify your connection is secure" would just endlessly ask me to click the button and never continue. Sometimes it would say to unblock access to challenges.cloudflare.com.

But if I a launch an incognito window I can visit website with the challenge and it won't even ask! I've added all my extensions to run in incognito mode and everything still works, I can visit the websites in incognito just fine. So the one changing variable is incognito vs non-incognito.

I can have two windows open, one incognito and one not, and browse to the same website and the non-incog window will fail but the incog will just go to the site.

I thought incognito was supposed to only affect the session storage? Does it silently change other things to the running environment of the browser (about:config options, slightly different extension configs)?

Anyone know why this small change would suddenly allow cloudflare challenges to work?

As of recently, every time I try to watch someone on Twitch, where the video feed would normally be is the streamer's offline banner image. Chat is working fine, and is active despite the stream not being displayed on my end. If I check the Twitch mobile app the stream displays as normal, so I know they are currently streaming. I tried disabling all of my add-ons and restarting the browser to no avail. I am a noob, so please be patient with me. I have attached images of an example, but this happens with any live channel, not just ones I am following (I do not have any active subscriptions as far as I know).

I don't know if breakage is the correct topic. I keep Ring.com open to the dashboard in a pinned tab. A few days ago, I had viewed and cleared videos as usual and later returned to view new activity. The site requires logging in every 30 days and so seeing that I needed to do so was not a surprise. What was a surprise was that the login buttons were grayed out. I closed the tab, cleared the Ring cookies and cache and tried again. No luck. I wondered if there was some other setting that I didn't know about and decided to open a private window and try it there. To my surprise, it works. I'm stumped. I'll attach the raw data from the private window as a .txt file. Darn. I can only attach an image. Well, I have it available and can copy and paste it into a subsequent post if you think it would help
