How do I block all cross-site cookies and close the "first 5 times" vulnerability?

I was surprised today to visit a site and notice the "permissions" icon appear at the left of the address bar, showing me that cross-site cookies were allowed for this site. I have Enhanced Tracking Protection set to "Strict", so obviously this was a worrying thing to happen.

Looking into it a bit further, it seems Firefox provides a backdoor for cross-site cookies: https://support.mozilla.org/en-US/kb/third-party-trackers?as=u&utm_source=inproduct#w_managing-cross-site-cookies

  • "While cross-site cookies from trackers are blocked in Firefox by default, a site may signal to the browser that it needs to use them for important functionality. In this case, Firefox will allow a third-party website to use cross-site cookies the first five times (or up to 1% of the number of unique sites you visit in a session, whichever is larger) without prompting you. After that, Firefox will prompt you to block these cookies. Without your consent, Firefox blocks these cookies from that point because a site requesting access that many times may be a tracker."

This is most definitely not what I want!

I want every cross-site cookie to be blocked by default, unless and until I explicitly approve it. Is there an about:config preference I can set to achieve this?

Firefox 103.0.2 (64 bit) doesn't play YouTube videso in Private Window. The same videso play in s statdrad new window. Try: https://www.youtube.com/watch?v=0fiVciCs8zU which ironically won't play in private! Every time you press the play button you get about half a second of play before pausing. In standard mode it plays just fine.

OS - Ubuntu22 Firefox - Default firefox on ubuntu22 (Mozilla Firefox 103.0.1)

Use case - 1. Custom profile folder (named prof1) contains pref.js and chrome folder with custom css file. 2. prof1 is created in -> "/customData/profiles/prof1" 3. The folder "/customData" has full rwx permissions and is owned by $USER (not by root)

Output -> 1. When launching firefox mentioning the profile -> "$ firefox --profile /customData/profiles/prof1"

The browser does not load, but there is an error box saying Profile Missing Your Firefox profile cannot be loaded. It may be missing or inaccessible.


Questions -> 1. Is it possible to load firefox profile from root directory ? 2. If custom profile folder is created in "/home", then it is launching and working perfectly. How is this possible when the permissions and owner is same as the one in "/customData"

frustrated and thinking about moving away from firefox. why not let us choose whether to update or not??

cookies deleting you have to search for each and everyone (why not sorted by installed date???) then one has to delete all the site cookies that are ok cause such a big effort to clear cookies!

no longer able to bank cause bank changed their cross site settings and firefox wont let me through...have to watch the status in bottom left corner and hope I can read it fast enough.

Reference #18.62052017.1660274157.1f6107dd Other sites like my banking site I can access freely on Edge but cannot on Firefox. No error message in that case, just says error try again. All this started after I loaded Norton. I have had them look at the system, and they have, but also point out that it is not them as I can access the site from Edge. I have looked at the help page and their are thousands of people with the same query but no fixes! As a long term supporter of Firefox I am disappointed that I now have to use Edge to do most of my business. HELP

Without my doing anything, firefox has decided to download pdf files in its own html. I have changed the default to adobe rather than ask. When I open the downloaded file in adobe it comes down as an adobe file, I tell it to save as an adobe pdf, but it appears in file manager and then opens in firefox html. Worse, it, whatever it is, has gone into file manager and changed adobe pdf files, some of which have been sitting on my hard drive for some years, into firefox html files. How do I rectify this please?

Yesterday for most of the day Yahoo mail was working fine. Last night I was able to pull up my emails, but all the controls were not working, Can't delete, arrow up or down, settings won't come up. It's like all the tabs are not highlighted to click on. I haven't done any updates, nothing changed. It's not Yahoo, works fine in Chrome.

Hi, I am using Firefox 103.0.2 on a M1 Mac with an external sound card with multiple stereo outputs pairs (1-2, 3-4, etc.)

Whatever the system selection for default stereo output is (e.g., 3-4), firefox will systematically select the first output pair (1-2) of the external sound card. All other applications (Chrome, Safari, Music, etc.) output on the selected default stereo output (3-4)

I can see I am not the only one to face the problem but threads are hard to read and understand.

Thanks for your help! Theo

I keep trying to sign in on my new Win 10 laptop. I have been double-checking my email and password each time; I am 100% certain they are correct, as I receive an account authorization email each time I try; when it's obviously incorrect, it does not send this email.

When I enter the code I am given, I am told my password is incorrect. Okay, no problem, I still have my old device where I'm still signed in. I tried to change the password -- old password is incorrect?!

I have had the same password for much longer than what is likely recommended for security reasons. I *know* what it is and yet I'm still being told it's incorrect.

Please help me. I can't work on my projects without my browser set up properly on my new PC. It's absurd that I can't even change it on my old PC.

Hello,

After installing Firefox (103.0.2) on a clean install of Manjaro (21.3.7) Gnome (42.4), I started noticing that mouse hover effects such as highlighted tabs, UI of a video-player appearing etc. are delayed after my PC exits hibernation (I am not sure if that is the only cause and if that really IS the cause). Weirdly enough the select menu I used to answer the "Which topic best describes your question?" question to create this post experiences no delay in highlighting the hovered element. Relaunching Firefox fixes this issue temporarily.

To be clear this is no performance issue since everything except mouse hover related interactions are fluid.

Thanks for helping out

//Firefox 103.0.1; Linux 5.10; Debian 11.4.0; xserver-xorg 1:7.7; Nvidia 515.57 driver// After clicking on ->Web Browsing -> Firefox there is NO visible response for 26 seconds... then a normal application window opens and Firefox appears to be operating normally. Opening via command line gives the following "error/information" message(s): glxtest: VA-API test failed, failed to initialize VAAPI connection. For the TWENTY-SIX seconds(!) Firefox is apparently trying to connect to a service that is not available. Is there something in "Settings" or in "about:config" that I can do to skip the "glxtest" and/or other glx VAAPI related configuration options? Or, alternatively, am I missing something in the X-window configuration or another library package that is necessary to support the VA-API feature? The Nvidia driver indicates it is providing "GLX server" version 1.4 . [Troubleshooting information / Share Data attached]

So, I just saw an add-on nesting on my "Connected Service" list. It's quite weird, because I never see something like this. Is this normal? The add-on is "video downloadhelper". Since the list description is "Everything you are using and signed into.", it it true that my firefox account has been compromised?
