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.

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 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

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.

Firefox 120.0.1 Memory Leaks, Windows 11 & 10, not a new issue

Firefox uses too much memory, sometimes 20GB on a 32GB Windows machine. It's usually one or two threads which are hogging incredible amounts of memory. This time I had about 30 tabs open.

Today I tried Firefox about:memory "Minimize Memory Usage" several times, and it was largely ineffective.

I did a "create memory dump file" of one 5+GB bloated thread using task manager, but can't find a way to upload the compressed archive with this report for analysis. Finding a way to report this issue was quite a challenge. It seems most help avenues are now missing/moved, and other reports of this type of issue are "Archived".

I tried killing the 2 bloated Firefox threads and checked for tabs which might be missing or malfunctioning. Everything continued to run normally while more than 10GB of memory was returned to system use. Leaving these bloated threads overnight doesn't improve anything, in fact I can often get up and find my machine is completely out of memory because Firefox consumed it all. My smallest machines have 16GB RAM.

These memory issues aren't new. I've been reporting them off and on for more than a decade. They get better for a few months after reporting, then they get bad again in a few more months. The battle to get memory leaks fixed is continuous while Firefox springs more leaks.

I'd like to give you the memory image I generated so you'll at least have some real data to look at and analyze for this report.

The attached task manager snapshot image is a very minor example of this issue. The numbers keep increasing like there are one or more large memory leaks.

I've downloaded and installed and updated Firefox on a new windows 11 PC - and I have a perfectly working installation on my (old) windows 10 Machine, so I'm well used to the browser! I've downloaded, installed and enabled three core, up-to-date addons: IDM, Adaware and Internet downlad helper: however NONE of them show on the toolbar and none of them function. And I've tried (I hope) all internet-search-suggested remedies such as reset Firefox etc. ad nauseam. All without success....

Later version refuses to connect to my modem, and goes into security web mode. This modem uses HTTP/HTTPS for access, i.e., connects directly it's IP address, then the user enters a username and password. At that point, the the modem switches to HTTPS for control.

With this recent update, there is NO WAY to access the modem for any work, or upgrade the HTTPS certificate on the modem. This is a BUG.

What should happen is that if the web site will accept a HTTP connection, Firefox should NOT refuse connection or test for security issues UNTIL the user or the device switches to HTTPS.

As an aside, I've used Firefox on this Zywall modem for years until recently.

These sites, and others, have worked fine for years. How can I fix this without turning adblocker off?
