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

So I have the latest version of macOS Ventura, the latest version of Firefox, and the latest version of Roblox. Whenever I try to open a Roblox game from their website (yes, I know. Roblox now has the desktop app so you don't need the website to open a game), it opens the app, but not the link, which means it doesn't open the game :( Does anybody know how to get Firefox to open the link and not just the app? (Btw no hate on firefox)

I really love Firefox and think it to be one of the best browsers but just there is one problem with it. It really uses a lot of my battery and ram of my Macbook air M1. The amount of battery usage is significantly higher compared to other browsers (Even about 10 times more!), It is my request to Mozilla to fix this problem. Firefox is really awesome but it uses a lot of resources.

Acting on advice provided by the Computer Active magazine I have installed uBlock Origin in order to block adverts. I was advised to stop using Adblock Plus. Adblock plus had an icon which I could click to see if it was working. uBlock Origin doesn't seem to have any visible icon. The add ons manager indicates that uBlock Origin is the only enabled extension, but is it doing any advert blocking? Shouldn't there be a clickable icon?

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.

As a Firefox user, I want to be able to whitelist websites as they continue to be impermissible to people using their website without having to give up all privacy, such that their website works.

Replication Steps: 1. Open Firefox Browser 2. Go to top left and click hamburger icon (3 horizontal lines) in top right under the close option 3. Click Settings 4. On left side click privacy and security 5. Locate permissions in the submenu 6. Location -> Settings 7. Add website into search bar and hit enter to add to whitelist

Current Result: Cannot add to whitelist and cannot utilize website with browser. Will be forced to use competitions browser.

Expected Result: Site would be added to whitelist and therefore allow use of a site that is arbitrarily adding forced location permissions because vpns are well... hurting their bottom line to be frank.

For the last several years I have had Firefox configured to display all website fonts in my custom font, Dyslexie. As of upgrading to v119 yesterday, I have lost this function; all websites now display their native fonts. I still have Firefox Settings Default Font set to Dyslexie, but it no longer works. Any help would be appreciated.

Until recently, this extension had worked well on YouTube, where downloading videos has usually worked for years without an issue.

However over the past month or so, when using the Linux system, it's become impossible to download any video from YouTube, without an error popping up after a couple of seconds.This occurs whatever choice of aspect for a video is available, be it in mp4 or mkv format. I should emphasize that this issue only seems to occur on YouTube. Other unrelated sites that host video-sharing still work with Linux.

In Windows 10, Video DownloadHelper with YouTube still seems to be working as normal. So any ideas why I can no longer use this extension with Linux and YouTube?

Regards,

I recently replaced my mouse on my PC. Now, when ever I click Firefox, MSN comes up. I have tried to delete MSN but it does not show up on any program. Please advise about removal of MSN so that I can continue to use your website which I have enjoyed for many years.

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

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.
