Possibly there was an auto update of MOZILLA FIREFOX on our DELL LAPTOP (Windows 11). Now, we cannot get a Mozilla window to open - due to error message:

XUL Runner Error: Platform version '118.0.1' is not compatible with minVersion >= 118.0 maxVersion <=118.0

Can someone please help us get back to a previous version of Mozilla Fire. Perhaps it is a Windows error. I have no way of knowing. Please help me. My email is: [removed email from public] Thank you.

On our online application we are facing with some strange behavior for a small percentage of our firefox users (<1%).

When doing oauth2 authorization, after generation of the authentication token we redirect to another platform but we are detecting that for a small percentage of Firefox the cookie (my_auth_cookie) with the auth token is not present.



GET: https://www.mywebsite.com/application/login Response:

new location https://www.mywebsite.com/otherapplication/redirect


set-cookie: my_auth_cookie expires=Mon, 04 Dec 2023 13:49:15 GMT; domain=.mywebsite.com; path=/; secure; samesite=lax; httponly


      2. GET https://www.mywebsite.com/otherapplication/redirect
          Set-cookie: mycookie: value
          Host: www.mywebsite.com


In cookie tab I see my_auth_cookie (value: xxxx, domain: .mywebsite.com, expires: Mon, 04 Dec 2023 13:49:15 GMT, httponly: checked, secure: checked,SameSite: Lax, partitionkey: empty, Priority: medium



I’ve tried to replicate but without success (with multiple extensions, including multi-account containers), with multiple configurations of Total Cookie Protection.

Again, this only seems to be happening to a very limited number of firefox users but for these, it happens 100% of the time. We see it occurring for versions 119 and 120 but now and then for older versions.

Feedback reports no extensions&addons.


Any ideas on what we could be dealing with? Any help would be greatly appreciated.

Spotify webplayer on Firefox is unuseable after updating to latest version

Majority of the songs do not play and I'm given with a pop-up, "Spotify can't play this right now. If you have the file on your computer you can import it."

I will play a song from a playlist and is given that pop-up, it will continue skipping to the next song until it plays, but only for 9-10 seconds until the song mutes, to specify, the dot (when hovered on the progress bar) will still move, indicating that "it's playing".

Some clarifications: 1. I use Spotify Desktop app (windows), Spotify App (android), and Spotify Webplayer on Chrome and Firefox. Everything works just as fine on all of these, except for Spotify Webplayer on Firefox. 2. Skipping to a later timestamp does not unmute the song. 2. I have Spotify Premium 3. I have no VPN 4. I am running Firefox with an ad blocker 5. I am running Chrome with an ad blocker (same ad blocker in Fifefox) 6. I am running Firefox to the latest version (Firefox 119.0.1 (20231106151204))

What I've done so far: 1. Cleared caches and data. 2. Updated my Windows to the latest update available - Win10 v.22H2 3. Signed-out of Spotify for all my devices, then logging-in first on Spotify Desktop (this automatically redirects to Firefox webplayer) 4. Ran Firefox on "Troubleshoot Mode" 5. Un-checked and re-checked "Play DRM content" setting. 6. Disabled and re-enabled the plug-in "Widevine Content Decryption Module by Google Inc". (this plug-in is last udpated on November 17, 4.10.2710.0

I'm including this link from Spotify's Community page.. where two other users, who commented it is only with Firefox (webplayer), are experiencing the same problem as I am. https://community.spotify.com/t5/Desktop-Windows/Spotify-can-t-play-this-right-now-If-you-have-the-file-on-your/m-p/5679914#M123192

For the past few days, when I try to log on to PlayStation on Firefox, the sign-in page sits on a loading swirl after inputting email. There's a clear memory leak shown on Task Manager. The menu bar's right-click doesn't draw properly. FF can't be closed and needs to be terminated. The only extension I have is uBlock Origin disabled for this site.

This website works on Edge.

Attached is the broken menu from right-clicking the menu bar.

Amazon Prime Videos will not play on Fire Fox. The message says to update Firefox, but my browser is up to date as of today, 10-24-23. Their customer service can provide no answer. This has been an ongoing problem for several months. I have tried their trouble shooting steps of restarting my system, signing out and re-signing in on Amazon and closing and re-opening Firefox. Allow DRM content is checked on my settings. Thanks.

Clicking on Firefox icon to log in I receive following message and gray screen. firefox.exe - Entry Point Not Found " The procedure entry point Flush could not be located in the dynamic link library C:\Program Files (x86)\Mozilla Firefox\xul.dll." Followed by another pop-up. "Could not load XPCOM" There was an automatic up-date several days ago and I have had this problem ever since. Is there a fix?

I'm running version 118.02.2 (64-bit) of Firefox on Windows 12. I *always* have the 'Open previous windows and tabs' checked. Starting yesterday, Firefox opens with nothing other than a blank page. Luckily for me, this has happened in the past and I have a Bookmarks Menu folder with my default tabs saved. Even so, it's still frustrating.

I wish to install and use the Firefox browser on my old 64bit Windows 7 laptop.

I believe the last v115 will be the last Windows 7 compatible version of Firefox, if this is correct where can I find this or the correct version of Firefox to download and install on my Windows 7 laptop?

The Firefox website only seems to provide v119 now.

Thanks, Graham

I have multiple monitors and most often have Firefox windows open on each. Lately, I've been noticing that the Desktop Window Manager process is consuming a huge amount of RAM. At the same time, consumption completely disappears with the closing of Firefox windows. Video: https://i.imgur.com/pHCa7Hh.mp4 (I left it for a while then closed Firefox windows) After a while, I noticed that already 13 GB of memory is being used by DWM. I don't know if sites affect behavior, but most often I have https://music.yandex.ru/home open

OS: Windows 11 (Microsoft Windows [Version 10.0.22621.1928]). Firefox: 115.0.1 (64-bit) Screen setup: 1 - 3840 x 2560 with 200% scale, 2 - 1920 x 1080 with 100% scale.
