I cannot login to my office.com accounts with Firefox. Chrome & Edge work fine. Attempting to use Firefox will get me as far as the "Stay signed in?" prompt, then dump me back to the sign in screen: I have refreshed, re-installed, installed a previous version, used Revouninstaller to get rid of all traces of Firefox, deleted the Mozilla folders from the appdata folder and reinstalled + tried using a private window. No joy with anything. I believe this is the key phrase from the error message (quoted below): "client request loop"

If I try to login @ outlook.office.365.com, I get

I updated my Firefox today and now videos do not play.

I had this problem back in April after an update and I spent weeks troubleshooting it. Eventually I got it to work after trying all of the following (then, and again now):

Things I've Tried: 1.) Clearing data (cache and cookies) 2.) Turning off "Strict Mode" 3.) Running CCleaner 4.) Disabling/enabling HW acceleration 5.) Checking that the DRM box is checked (and trying it without it checked) 6.) Refreshing Firefox 7.) Uninstalling/Reinstalling 8.) Updating my Windows install 9.) Updating drivers 10.) Disabling all Firefox extensions 11.) Running without extensions 12.) Running in Firefox Troubleshooting Mode 13.) Running Windows in Safe Mode with Networking 14.) Running a fresh install of Firefox without signing in after deleting all traces of Firefox from my PC (including Program Data folders, registry entries, etc.)

What finally worked back in April was to dive into "about:config" and change "media.rdd-processenable" to "false".

That fix does not work this time around.

In the meantime I've been using Brave and having no issues. I've tried video playback in Chrome, Opera, and Edge on this computer with no issues. This playback problem is exclusive to Firefox.

Video playback still works just fine on my 4 home PCs running Windows 10 and Pop_OS (3 self-built, one Asus laptop) using this same build of Firefox.

Other/Rant: I suspect this is a Firefox/Windows 11 problem. Most likely this is not something I can fix myself, but it's incredibly frustrating since I'm buried deep in the Mozilla ecosystem and use it for work. I'd prefer not to have to swap between browsers just so I can watch videos; too many windows open on this tiny work laptop isn't fun to juggle. Basic video playback is the #1 thing I use my web browser for at both work and home so it'd be nice if this irritating, months-long, unacceptable issue were resolved. A modern browser that has video playback issues? What good is it then? What's most irritating is that it seems I'm the one of a very small number of users with this issue, since I see very little posted about it online.

I've been a Firefox user primarily for almost half a decade now - moved over from Chrome for privacy issues. Never had a problem until 4/22 of this year and considering it's still an issue 3 months later... it has me re-evaluating the reliability and my commitment to an otherwise amazing browser.

Hi there, I have an old laptop which has FireFox installed on it with a lot of older Browsing History dated as far back as 2015 or 2016 which I've been attempting to transfer over to my newer Laptop's FireFox by synchronizing my FireFox account on both browsers. The bookmarks & tabs were synchronized between both, however, the browsing history from the older laptop doesn't transfer over to my newer laptop's Firefox.

I searched online for some troubleshooting, & discovered how to use about:config, where I found

1. "places.history.expiration.transient_current_max_pages'" &
2. "places.history.expiration.max_pages",

& for both I set the value to 999999. The result was the same.

I would like to inquire for assistance regarding this, if possible. Thank you!

Firefox is the only browser that I cannot load a site.

With firefox I get: Secure Connection Failed

An error occurred during a connection to licensing.nypdonline.org. Peer’s Certificate has been revoked.

Error code: SEC_ERROR_REVOKED_CERTIFICATE

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.

All other browsers see the site as OK

Hello,

Uninstall for Firefox does not work. 

When I try to uninstall a "refresh" window opens.

I do not want to refresh, just uninstall.

Whatever process I try yields the same result.

Thank you Ben

So today I wanted to try FF Containers, because I have service user to manage O365, my normal company user and my personal user.

Now I open make.powerapps.com in container dedicated to this site I log in with one of these users everything is ok, but during first sign-in I am not asked even for password for specified account, I just enter email and then I am redirected and signed in. I have disabled "Allow Windows single sign-on for Microsoft, work, and school accounts". When I want to access portal.azure.com in another container, I am automatically signed in with user from previous container dedicated to powerapps.

I especially logged out of all containers and removed all cookies from FF before submitting and it is still happening

Also checked Windows "Internet options", I do not have any of these sites in "Intranet sites" and Level for all zones regarding to User Authentication is "Prompt for user name and password" dunno know what is wrong.

I need to install Firefox in this computer. Is not working, I need this to play my Farmville2 is still no work. Please do something, I need this. att. Raquel R Orlang

Hi - my BitDefender Internet Security found this Trojan.GenericKD.62058384 in my firefox profiles folder - C:\Users\david\AppData\Local\Mozilla\Firefox\Profiles\v6jicbrz.default-release-1662311998698\cache2\entries\E4A4EB628D5AE50B559489046BF17891EBE92F04=>(gzip)

Is this a false positive? This cache is nearly 1GB in size, are all the files needed?

TIA davidj

Trying to use ProctorU with Firefox 104.0.2 on Windows 11 Home, and I am getting the following message : "Monitor Count : You may only use 1 monitor during your exam. Your monitor count could not be found". I searched for possible fixes, and someone mentioned removing fingerprinters, and possibly also remove cookies and tracking content from Firefox enforcement. I removed all 3 and that did not help. I also tried clearing cookies and site data and also cached web content, this did not help. Is there some other setting in Firefox that might be preventing the detection of the monitor count? Any suggestions on how to fix this issue?

I am using Firefox 105.0.1 on a Windows 11 computer. I have sufficient gpu and cpu power to run 4k videos in full screen with no choppiness or lag. However, when I exit full screen mode it seems as if frames are being skipped. I am using LocalCDN, Ublock Origin, and container tabs.

Is there any reason for this to be occuring?

Thanks

when reopening closed tabs it doesn't open last closed tabs, it only opens closed tabs in the window you are using. so if you have closed a window it doesn't reopen like it does on chrome

Whenever I print my transfer transcript, it will always combine both the pages into one page. Using other browsers, I would be able to just print the first page but I do not have the option in Firefox. I would like to be able to just print the first page and not the combined page 1 and 2. Thank you.

When i attempt to start firefox it doesn't open or will instantly close and then close the error. It does give me a crash report, starting in troubleshoot mode does not change the outcome. I have reinstalled several times and don't know any other way to try to solve this.

I have already tried

• Cleaning cache
• Troubleshoot mode
• Cognito/privacy whatever the heck is called mode
• [https://support.mozilla.org/en-US/kb/refresh-firefox-reset-add-ons-and-se...]

It keeps loading forever

The VA is updating their website which is a joke. When I try to login to their website it puts me into a loop which keeps asking me to verify my ID. Frustrated, I changed back to Google and it worked fine. I don't know how to fix this or explain the problem anymore, but I really like FF but things like this makes me hesitant to continue to use it.
