Hello everyone,

I keep having the issue that on some websites, a whole list of cross-site cookies is displayed when i click the icon to the left of the address bar. "These parties can use cross-site cookies and site data while you are on this site."

Especially Google (I am not logged into a Google account) lists many different sites here. I can then click on "Allowed X" - but after a few days, the entry appears again without me being asked!

Under "Privacy & Security" I am using the Standard level. It says there: "Firefox blocks the following: (...) Cross-site cookies in all windows (...)" So why are some still being allowed? How can I generally prohibit them except for those I manually allow? The five levels for cookie handling under "Custom" are unfortunately not very self-explanatory, and I can’t find any whitelist option there either.

Thanks for any advice! Best regards, Martin

Hi Firefox support,

I’m experiencing a persistent issue with Google Fonts (.woff2) on Windows 10. Only on some but not all pages whoch are using Google Font woff2: Fonts display correctly after starting Firefox, but as soon as I reload the pages with for the first time, they appear corrupted and remain broken. Private Browsing mode renders the fonts correctly, and Chrome does not have this problem.

Below is a detailed list of everything I’ve tried with ChatGPT so far to troubleshoot the issue.

(OS: latest Windows 10)

Browser: Firefox (freshly installed, no sync)

Behavior:

Example site: https://www.linguee.de/

Steps already attempted:

Disabled all extensions

Tested in Firefox Safe Mode / Troubleshoot Mode

Created a new Firefox profile

Fresh Firefox installation without signing in

Deleted all relevant caches:

%LOCALAPPDATA%\Mozilla\Firefox\Profiles\<profile>\cache2

%LOCALAPPDATA%\Mozilla\Firefox\Profiles\<profile>\storage

%APPDATA%\Mozilla\Firefox\Profiles\<profile>\startupCache

%LOCALAPPDATA%\Mozilla\

Verified / adjusted Firefox config in about:config:

browser.display.use_document_fonts = 1

gfx.webrender.all = false

WebRender running in WebRender (Software) mode

privacy.resistFingerprinting = false

browser.cache.disk.enable = false

network.http.rcwn.enabled = false

accessibility.force_disabled = 1

Disabled hardware acceleration for testing

Tested DirectWrite / Direct3D settings

Recalibrated ClearType

Ran sfc /scannow to repair system fonts

Temporarily disabled antivirus / web protection

Tested behavior in private mode versus normal mode

Observed that hard reload (Ctrl + F5) does not fix fonts

Noted that only .woff2 (Google Fonts) are affected; system fonts render normally

Summary:

Issue is not caused by extensions, profile, cache, or a fresh install

Private Browsing works → problem is related to persistent normal-mode caching or rendering

Only occurs in normal windows, consistently reproducible after first reload

Problem seems specific to .woff2 font handling and Firefox’s rendering pipeline on Windows 10

when attempting to login to 53.com credentials are entered, login pressed, login flashes but no login.... as if there is a pop up or something that should occur and doesn't. On edge it works fine, press login and a clock like symbol overlays the login button and then you are in....

Hi all,

everytime I open Thunderbird I get a popup window from Yahoo finance with a server timeout message. I am unable to connect to get my emails through. I need to log on directly to Yahoo mail, which is a pain.

Hopefully someone can help me with this.

Find attached the popup image.

When using vertical tabs layout with "expand sidebar on hover" setting enabled, sidebar scrolls up with each expansion, so that when hovering over a certain tab of collapsed sidebar, another open tab is under the mouse pointer when expanded. For additional details please refer to the attached video.

Steps to reproduce: 1. Enable vertical tabs layout with "expand sidebar on hover" setting 2. Open a lot of tabs 3. Hover over a certain tab

Observed result: The sidebar expands with mouse over another tab and the list of tabs scrolled up.

Expected result: The sidebar expands and mouse pointer is hovering over the same tab after expansion from collapsed state.

Hello, For 2 unsuccessful hours of trials, Mistral didn't help me, nor the configuration editor (but there are so many parameters...). On Windows 10, with Thunderbird 140.7.2esr : when clicking on http/https links in messages, I would like to make thunderbird opening my web browser but in private mode, while this mode is not the default one. I know the flag to use to run the browser in private mode from a command line, and it works. But i do not know how to declare it for/in Thunderbird. Mistral answered me that there is a network.protocol-handler.http param to set, but i have not found it or somewhat similar in the config editor. Any help would be welcome. Even better would be to be able to choose through a contextual menu how to open the link, as it is possible in the web browser. Thank for any hint.

Whenever I click on the Firefox icon to start, instead of FF, AOL comes up. I looked on my C: program list and it is not listed so I can't delete it. It just started doing this in the last week. I tried downloading FF again with no luck. Its on an old windows 10 machine.

Whenever I create an event in the calendar, Thunderbird creates it in the "Task calendar" and I want it in my other, email named calendar. Can this behavior be changed? It's so frustrating because I have to edit the event and all the attendees get a second notice. Thank you

Hello,

I'm using lasted version of Firefox Desktop and also using Kaspersky VPN. Whenever vpn is deactivated I cannot connect some websites. I just clicked and nothing happens. But if i tried with activated vpn, it's connecting.

I was trying to solve this problem but cant find solution.

PS. I did try on other browsers(Edge and Opera). I just connecting whatever is vpn status.

v148, Win 10

The site froze while playing a video. It happened multiple times. Is anyone else reporting this kind of behavior on Instagram. I closed the tab, but cpu stress-like side effects remained for a while.

Noticed the bookmarks error message at the top of the browser page then looked to find they were gone, no troubleshooting methods have worked and I don't seem to have any backup files. Bookmark manager is blank and there are no selectable options?

Several days ago Firefox deleted all of my saved passwords. When I built up a new list of saved Passwords, they are all deleted and gone the next day. Why is Firefox doing this?

Couple days ago my Thunderbird stopped connecting to Gmail POP server, returning an error that the server is unavailable. The Thunderbird version was way too old and didn't have OAuth2 option, so I updated to the most recent version 140.7.2esr. Nevertheless setting OAuth2 didn't help.

Then I deleted completely the Gmail account and all saved passwords related to it and created a new mail account for Gmail from scratch. But connecting is still not happening.

Receiving of cookies is enabled. The parameter javascript.enabled is set true. What else can be checked for possible cause of the authentication denial at Gmail's side?

The main reason I use Firefox rather than Chrome or Edge is because Firefox allows 32 home page shortcuts. I configure my home page with all 4 available rows of 8, pinned in position so they are grouped based on function, along with putting the home page icon on the toolbar. On several occasions these have disappeared and the 'popular sites' do not load. I have had to use Control Panel -> uninstall program to 'fix' Firefox; this causes all my shortcuts to disappear, along with the toolbar 'home' icon and '4 row' display. I am running Windows 10 Pro, and will be migrating to Windows 11 Pro on a new computer. Will this issue be fixed with Firefox running on Win 11? Is there a way to easily save my home page settings so that if they disappear I can reload them? Thanks!

My shortcuts keep disappearing from my home page when I turn my computer on. Sometimes it's fine, sometimes I have to spend a long time trying to find them. Sometimes I just have to restart Firefox. Sometimes I have to go into settings. Sometimes I can't work it out.

Has been happening for the past month or so.
