Hello,

I work for Microsoft, and one of our sites offers users a way to opt out of personalized advertising on some Microsoft domains by setting a cookie. The site: https://account.microsoft.com/privacy/ad-settings/signedout

When the user clicks the toggle to Off, we cycle through four domains via an iframe and write a TOptOut cookie on each one. If everything is working properly, the user should then be able to go to www.bing.com and see a TOptOut cookie on Bing that will prevent personalized advertising on that domain.

The problem is, this stopped working in Firefox. We have verified that it still works* in 115.7.0, but in 122.0.1 and 123.0, the cookie is written and then deleted on refresh. If the user doesn't already have Bing open in another tab, they'll never see the cookie at all. I have verified this behavior in Bing several times, on my work machine (Firefox 122.0.1 on Windows 10) and my personal machine (Firefox 122.0 snap on Xubuntu 23.10).

  • It still works on our corporate VPN in 115.7.0, but not on my coworker's non-VPN machine. Same version. I'm really not sure what's up with that one.

This is a large concern for us. Because the cookies can still be written, it doesn't trip our test for third-party cookies being disabled. Because the cookie for microsoft.com is written, the toggle will show up as Off even after a refresh. This is misleading to our users.

I have gone over the Firefox docs on Enhanced Tracking Protection and Total Cookie Protection, but neither seem to handle this case. Firefox does not block any trackers on account.microsoft.com or on www.bing.com. It's fine if the cookies are in separate jars, we just want them to be written to the proper domains and not deleted. Can anyone tell me what changed in Firefox recently? Is this expected behavior, or a bug? If it's expected behavior, what can we do to allow users to opt out of personalized advertising?

Since the last Firefox update I have been unable to login to my bank's website. Attached is a screenshot of the message that appears. As a test I tried logging in with Google Chrome and was successful so it is likely something with the last update of Firefox.

Last time I tried backing up my bookmarks, they were saved in a file that was basically a list, a list that can't be imported back to Firefox bookmarks, but just a list. I would like to know if there's a way to actually export and import bookmarks with one click, rather than me having to add 200 pages from the list manually. When I tried importing the file, the list ended up somewhere random and not where bookmarks are

I am one among many who keep a lot of windows open for reference. When my compootie shuts down inadvertantly I am avle to use "Restore Session" to get these back. But occasionally the system shuts down and I am unable to restore anything, and this can cost me tens of hours os referencing, and untold hours of productivity.

Could you save the open windows in an easily accessible file that we could use to restore previous sessions? This would save a lot of us considerable grief.

Hi,

I'm trying to remove the bar at the top of firefox browser with tabs in them. I read another article (https://support.mozilla.org/es/questions/1417387#answer-1588947) under spain link, i think, and the solution said to write "TabsToolbar-customization-target { visibility: collapse !important; }" somewhere. Where do I go to write that?

I tried the console by pressing f12, but that doesn't seem like that's it. In that article it also mentions to go to about:config and change the status of "browser.tabs.drawInTitlebar" to false, or delete it, but didn't work either.

WED 21FEB24 The urgent issue is that in the last few weeks, many web pages do not load content, just a grey or white screen. Some will load the header. I am the Executor for someone's estate, and I am having this trouble with some financial websites that I must access to do the job.

Its been many years since I upgraded anything. It might be that Macintosh Firefox 78.15.0 esr (64 bit) and Thunderbird 60.9.1 are the newest revs that work with OSX 10.11.6 El Capitan. I have a 2011 MacBookPro.

I don't like the changes in the user interface that Apple put into OSX after El Capitan. But I may be forced to upgrade. Too late in life to learn Linux.

Maybe the minimalist solution is to upgrade Firefox. But that may require upgrading OSX, and Apple has made it really hard to do that unless you go to the very newest. OTOH I don't know if the newer OSX will run on my 2011 MacBook Pro. If I clicked on "software update" in About This Mac, what would happen? would it just start doing it, or tell me about it first?

The last time I upgraded something, probably Thunderbird but maybe it was Firefox, I had to learn a complicated process to copy & save the User Profiles (they are in a hidden directory), and then install them into the new rev. I don't want to go through that again. I just want to run the dmg file.

There used to be a Mozilla web page with all the versions & you could download the dmg file you wanted.

If I still have problems, I would have to buy a much newer computer. A several year old MacBookPro. But I don't like the "new" disk formatting method Apple created. It saves space by not actually making copies of files, but uses a pointer to one copy. So there is a single point of failure, which makes copies pointless. I want to keep using OSX Extended (Journaled) and I would have to have the seller of the computer do that for me, before I used Migration Assistant to put my stuff on it. I also hate the welded-on hard drive; being able to pull the drive is the best "broken hardware" solution.

I don't recall if El Capitan has the "OSX Recovery" system or if that happened in a later rev.

I use SuperDuper to make a clone of my hard drive as a backup & archive. I wonder if I could connect a copy on an external drive and then startup using the external copy. Then I could upgrade Firefox and see if it works, then do the same for OSX if necessary, and Thunderbird.

Suggestions & how-to info needed. TIA

I do not know how I got there, but I somehow got into a situation where I could push a button 'Refresh', or in Dutch 'Opfrissen'. Firefox then started to remove settings and extensions. Which is all well documented if you know it. But the user interface is just crap here. Especially in Dutch. Because 'opfrissen' is something that sounds totally innocent in my native language. I at most expected it to remove some cache memory. The last thing I expect pushing a button with that name is that it does what it did, without any warning! PLEASE change that. And please do not translate it with 'opfrissen', just explicitly say: Go back to standard configuration and remove extensions. I am not dumb that I could not understand what that should do. Opfrissen.... Pfff, please change at least the translation!

And I got really angry when it happened!

Hi there,

I'm migrating from Arc Browser and I was looking for a way to have two profiles, one for personal and one for work; for each have separate browsing history, cookies etc. and be able to switch between them either with a keyboard shortcut or in two clicks like in Arc.

If I understand correctly I can separate the users by going to about:profiles and creating such profiles, however the switch between them doesn't seem as seamless. I guess I'd like to create two separate workspaces rather than profiles, with complete separation of everything I do within each.

I tried the Multi-Account Containers extension but it doesn't seem to be this its purpose.

Hope I was clear in the explanation, apologies for the newbness.

Thank you!
