Firefox Support Forum

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.

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

From: Dell XPS 13 (5 years old) on Windows 11. Up to date with The most recent version of Firefox which I believe is 120. Always stay up to date.

To: Dell XPS 13 (brand new as of this week), Windows 11 with all updates and Firefox most recent 120 again always up to date.

I have tried reading several articles on here and using different methods from multiple answers and threads and have failed to find a method which exports All of my bookmarks from my old computer to my new computer.

NOTE:

Would highly prefer a method that replaces all bookmarks and data on my new computer exactly with everything from my old computer!

I don't care about my bookmarks on my new computer because I don't really have any but I do care very much about my old ones. At one point when I was syncing them, The bookmarks on my new computer which didn't include The vast majority of them disappeared from both computers for a short time until I restored to a specific different date a few times and luckily have my bookmarks on my old laptop still.

I have tried exporting them as a JSON and as an HTML to put them on my new computer. I've read the HTML method puts them all in one place as opposed to replacing all of them. Obviously I would prefer the JSON method. However I have tried both with no success. I've also tried moving them into the documents folder both times as recommended. I've tried to restore to date on the new computer.

Transferring bookmarks individually would be way too time-consuming as I have a ton of different folders.

Someone please help me find a solution to do something which should be basic which is transfer all my bookmarks for my old computer to my new computer. I'm also logged into my Firefox same account on both computers and have tried syncing with no success as well. No matter how many times I do it. I repeated all of these processes many times with small variations.

Please someone help me get my bookmarks! Thank you for your time and help!

Best regards,

Nate

When I open FIrefox it opens briefly maximized, then reverts to minimized, then returns to maximized. I'd like it to open maximized, period.

When I close my sessions there is only a maximized window open. There are no minimized windows open.

How to do I change this behavior?

HELP!!

Every time I open Firefox Bing comes up. How can I get rid of Bing completely and forever? I hate it ! I don't want it!

I've tried going through add-ons, I've tried deleting all of the Bing files that I can find.

HELP!!

PLEASE!!!

https://forum.skylords.eu/uploads/stronghold_bombardment.mp4 This file can not be played with error message "Video can't be played because the file is corrupt.", and there is not even an option to download the file. Same file works fine in Chrome, Edge, VLC media player, ...

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.

For the last two days, cnn.com won't load and gives a message that the browser is blocked. Can you explain how I can remedy that? It's a rather popular site, so I assume Firefox will want it to work. All my other sites are working fine, so I'm assuming it some adjustment that cnn made on their end.

In macOS you can set up a global keyboard shortcut for the Move Window to Right Side of Screen command via System Settings > Keyboard > Keyboard Shortcuts.... In most apps that support the Move Window to... commands, this will simply move the window to the desired side of the screen when the key combo is pressed.

However, in Firefox the key combo will start the animation as normal but the window will then bounce back to its original location. It's only when the command is activated via a keyboard shortcut that it does the bounce back behavior, though; the command works as intended when activated from the Window menu in the menu bar or from Option + green button in the top left of the window.

The key combo I set up was Shift + Option + Command + Right Arrow, but I've also tried a couple of different key combos and they all did the same bounce back behavior. I've tried it on machines with different versions of macOS (Sonoma beta and Ventura) with the same result. The bounce back behavior also effects the Move Window to Left Side of Screen command.

My Windows Task Scheduler contains an entry called "Firefox Default Browser Agent". If I delete it, it returns. If I disable it, it re-enables itself. Can't be modified either. How do I turn it off permanently?

I already have telemetry and automatic updates both turned off.

In about:config default-browser-agent.enabled is set to false

I am prevented from downloading an important document because the site says that I need to disable an ad blocker. I am not aware of having an ad blocker and nothing shows up in add-ons and extensions. How do I find and disable an ad blocker that I cannot find?

While on michaels.com I click on a product, it goes to the product then immediately the screen goes blank. It also happens when I do a search, multiple products show up, then the screen goes blank. I don't have that issues on other websites. What is going on and how do I solve this issue?

For the past few days, the YouTube website has behaving unusually in Firefox. The volume and play/pause controls don't work. The picture in picture mode does not work. And most importantly, the search bar is broken. Whenever I type something and click the search button or press enter, the value entered disappears and I have to type it all again, only that this process goes on for infinite number of times and so, I can't even search for anything on YouTube.

I've noticed this issue happening randomly, some of my toolbar bookmarks listed on the sidebar just up and disappear from view. As if they were never there. But I know they're still saved because when I click to Manage Bookmarks and check them there, they show up fine. The toolbar just randomly hides them for whatever reason, and I can only fix it by closing Firefox and opening it again.

I'm on the current version. I remember accessing about:support and clicking on Verify Integrity while trying troubleshoot some other issue, but don't know if that could've caused it though.

Recently Youtube refuses to play any videos for me, saying adblockers are against their rules. I have uninstalled Adblock, and reset firefox totally. Youtube is still blocking me. It works fine on Chrome. Do I have to switch to Chrome permanently?

Why does firefox constantly ask for capchas on VPN when doing searches on Google? It is a serious problem. The vpn is for my security, not google.com

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....
