I can no longer view YouTube videos in Firefox browser because they think I have some kind of add blocker installed. I have never installed such a thing and have no idea how to fix what they are demanding I must fix in order to continue with YouTube in the FireFox browser. In the mean time I have to use some other unfamiliar browser just for YouTube. It appears that some kind of incompatibility has evolved in the recent two or three weeks between Firefox and YouTube.

I am unable to sign into Costco.com using Firefox. I get an error message:

    "Bad Request - Header Field Too Long
    HTTP Error 400. A request header field is too long."

Turning off all extensions didn't help. Opening a private browsing window DID work. Using Chrome DID work.

Thanks!

I stay logged into WaPo, NYT and some other sites on one PC. But after the most recent FF update, I have to re-login to all sites (but just on the first visit), or use two-factor authentication to have my device (PC) trusted again on banking and some other sites that I don't stay logged into. I also have to reset site preferences and customizations (such as presentation on SlickDeals), if sites provide the capability. Can I fix that?

I make daily backups, so I can restore a configuration file(s) from before the update. But, which one(s), if any?

Hi there. I appear to have some kind of issue/bug with Twitch. For some reason, some streams, seemingly at random, do not play audio. Closing firefox and reopening sometimes fixes this, other times it doesnt. For example, if I am watching a stream, I then close firefox, and use "restore last session", there is no audio coming from the site. Other sites such as youtube work fine 100% of the time. Doing the same on other browsers such as Chrome do not have this issue. I have tried reloading the page and it seemingly works at random, I have tried clearing the cache.

No videos appear at all on Teachable, just a blank space where video should be. I have allowed video and audio (video and audio work on many other sites). I have cleared my cache. I have to use a different browser to use this site. I have also noticed other sites that have the same problem.

Hi all,

Apple has revised/updated their iCloud web portal. The backspace key no longer registers in the iCloud Calendar app on the web. This is specific to Firefox on Windows - I've tried other web browsers to access iCloud web portal and Chrome's backspace key registers so its not an Apple iCloud problem, just Firefox. Is there a setting or do I have to wait for an update?

Thanks in advance.

Google Calendar has not worked right on Firefox (version 118.0.1 (64-bit)) on macOS since I updated to macOS 14.0. For example, when I try to use the "Search" function, I can't type a search string. Or sometimes when I create an event I have problems typing in the event title field as well. On these occasions when it doesn't work there is no blinking cursor placed at the left end of the text field, so you can't type in that field.

Hoping that this isn't just me, since I really like using FIrefox. Have had to move to the Edge Browser because Google Calendar is a central tool for me that has to work without having to fiddle around.

Until the most recent update of Firefox, I was able to access atrribute data of a GIS map feature on the GIS Open Data, State of Michigan website:

https://gis-michigan.opendata.arcgis.com/datasets/2020-voting-precincts/explore?location=44.909859%2C-86.310800%2C6.97

Now, I can not click on any feature. I can do this, however, using Chrome. What is the issue, here?

(This issue has been happening for several months, perhaps even a year or more)

My issue's example is me trying to log in to Duolingo. When I try to log in with google, a popup appears where I select which google account to use, the popup closes, and then the sign in button loads perpetually. I left it to load for over an hour and nothing happened.

I tried the same thing with Microsoft Edge and I could log in with google perfectly fine.

This has happened to me on other websites too, but the issue is worse with Duolingo because if you have a google account associated with Duolingo, it requires you to log in with google. I can't use my password to log in, so I can't use Duolingo on Firefox

What is going on?

After doing a reset to try and get rid of the yahoo redirect malware attached to the Firefox browser, now I cannot access google search engine within firefox, or my gmail email account. I get the error messages attached below. I have spent hours looking on your support pages and tried all ways and NOTHING WORKS!!!!

FIrefox has been my default browser for years but if you cannot fix this very annoying and frustrating bug, I will be forced to your Chrome.

Very unhappy with this

I am using a MacBook Pro and latest version of FIrefox 100.0

PLEASE HELP ASAP!!!!!

The problem is : Some of the time FF just records 0 bytes file and says nothing. I suspect that FF inspect the URL of the links and discard ( perhaps for security reason ) ones that do not begin with HTTP.

The bypass is : One has to copy the link and insert in in the new page of FF.

The solution would be to change FF code.

Thank you.

In order to reproduce:

1. Browse to klarna.com 2. click on [login] and then [login for customers] 3. page will redirect to https://app.klarna.com/login?market=de&utm_campaign=header-login-link&utm_medium=referral&utm_source=klarna 4. (you should have an account, if not just create one and proceed with following step) 5. click on [sign in] 6. enter email assigned with your account 7. click on [Confirm and Continue] 8. (a verification code is sent to the email or phone assigned with your account) 9. enter verification code 10. page will redirect to https://app.klarna.com/ and will show a frame where to adjust settings about how klarna will collect data by tracking technologies. 11. click on any button to close that frame (accept all / required settings only,...) ---> Does not work :-(

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)

The last Firefox update made my website not work properly. I have dropdown menus that are no longer clickable or responsive to hovering on Firefox after the last update. Please check Gardenerd.com. It still works fine on Chrome, so I know it's not my website. It's Firefox. Please put it back so people can access my site content like before.

I live in the northwest of USA and I use Banner Bank. The bank's "bill pay" service has quit working on Firefox. I've contacted them four times about this problem and each time they've got me connected only to fail the next time I try to use it. I've used Firefox for many years and I don't want to drop it for this one problem. Has this problem occurred with others? Maybe someone from Mozilla can contact them and fix the problem. r
