I'm a cybersecurity professional and I'm researching about Same Origin Policy, Cross Origin Resource Sharing and how firefox deal with those things. I've find out that versions before 102.1.0esr, cross-origin script GET requests used to attach cookies (Image 1), but in newer versions, it's not happening (Image 2). I checked the release notes but didn't find nothing about this change.

I would like to learn more about what changed and how Firefox is dealing with cookies, SOP and CORS.

Thanks!

I had several windows open each with different tabs in them.

I shut down them down and switched off my Mac.

On restarting my Mac, one of the windows had disappeared from the restore session. I've checked my History but the tabs don't appear there.

I'm using the latest version of FF on a Mac Air M2

Please advise.

Ever since I loaded 120.0.1 (64 bit) I have had problems accessing numerous sites. For example, https//HOn30.org. FIrst I get several "Having trouble ..." messages, and when it does come up it's a blank screen. I have had this happen wtih Library of Congree, eBay, and most sites from linking within another web site. I have tried playing with the "HTTPS mode" and the "DNS over HTTPS" to no avail. What changed with this version and how do I fix it.

My laptop died. I purchased a new one and pulled the SSD drive from the dead laptop and hooked it up to the new laptop with a SATA to USB cable and have access to the drive now. How do I pull all the information that was in Firefox (bookmarks, open tabs when laptop died, etc.) from the old drive to the new laptop?

Although strict privacy is set, I am able to logg into websites, although lock icon displays message "Connection verified by a certificate issuer that is not recognized by Mozilla"

Hello,

NOTICE: Currently using Firefox 120.0.1 "Update disabled by your system administrator" I am unable to update the browser, the computers are from the public library.

Like I state in the Subject, I configure the browser to strict privacy level, and I am able to visit any site I want. No problem. But on all of these, when I click the lock icon on the address bar I read "Connection verified by a certificate issuer that is not recognized by Mozilla." In fact, right now, I am visiting this website and I got that notice. View image "Firefox broser does not recognize the certificate issuer fortinet but I can visit the firefox suport website - Screenshot 2024-01-28 172732.png"

WOW... View the image "certificate issuer not recognized by Firefox - fortinet - when visiting support.firefox.com - Screenshot 2024-01-28 173041.png" for some of the info I get if I view more information about the certificate.

Then, after I logged out, the "Clear cookies and site data" link that appears after clicking the lock icon I mentioned before do not appear.

View the image "UNable to clear cookies and site data - proton.me - Screenshot 2024-01-28 141951 - edited.png"

In this same computer, I got the control "Clear cookies and site data." View image "able to clear cookies and site data - virustotal.com - Screenshot 2024-01-28 141825.png"

So more than one question:

I read other posts where users are unable to visit a website which has a certificate issued by an issuer that is not recognized by Mozilla. Why am I able to visit these websites?

What can I expect of the non appearing "Clear cookies and site data" link I described before?

Are these computers like totally hacked?

All items except but the top one (privacy) in the right-side menu in vimeo are partially hidden and so not fully functional. This problem does not occur in Microsoft Edge, and so it evidently is a Firefox problem. My system: AMD 3900X Running Windows 10 Home, Nvidia GTX950 graphics card, 32 GB memory, The image is a reduced-size screenshot from a 1920 x 1080 monitor. Adjusting the width of the window for Friefox has no effect on the problem.

Hi, Every time I try to open Firefox, a window pops up and asks to let it make changes to my computer. I checked the properties and I am not running Firefox as an administrator, which is what all the help pages said is the problem. I do not want to change the settings in my computer that would make the pop ups asking to make changes go away, as that is a significant security risk. Surely there must be another way to fix this issue? I have used Firefox for years without this problem and it is only just now happening. I love Firefox but this extra step is extremely annoying. Any ideas?

Thanks in advance

Greetings...

On a daily basis, I access a group of websites that use the same username and password for login, so logging into one of the websites automatically enables my access to each of the group websites, as a result of a cookie created by the initial login. As a result, I encounter only one login challenge as I actively access each of the group websites.

However, beginning in October, I began to experience repeated login challenges after I had successfully logged into one of the group websites. The repeated login challenges occur randomly whenever I selected a hotlink within the website. The repeated login challenges occur either within the website that I initially logged into or one of the subsequent group websites that I selected to access.

The only changes to my Firefox web browser have been the periodic version updates. I have tried making changes to the Firefox Privacy & Security settings, but the repeated login challenges continue.

I have also contacted the group websites support and advised them of this problem, but they have been unable to provide any assistance.

Could the repeated login challenges be caused by a periodic version update to my Firefox web browser? If not, then what else might be the cause?

Thank you in advance for your help!

Hi:

  I do genealogy and often have 20 or more WINDOWS (not tabs) open simultaneously.  I also rapidly type, copy/paste, between windows, etc. and can instantly detect slowdowns - especially irksome when the mouse disappears for seconds while the system is working.  I keep history and cookies...reminds me of pages I've already looked at when color change is enabled.
  After crashing a hard drive, I finally realized that Firefox was accessing the disk WAY too much.  Even with the system static (no page changes or updates), it was continually writing to disk.  Occasionally, it would take over the disk system for seconds.  Over time (years), as you guys improved, it became less significant; just broken up into lots and lots of small accesses.  Researched quite a bit...
  Started with increasing the sessionstore interval, but still was an issue.

To solve MOST of the problem, I saw a help note. I created and set to FALSE

browser.sessionstore.enabled

Plus modified several other sessionstore items This helped a lot...

   BUT this did NOT regulate sqlite storage for third-party stuff.

This is probably handled and hidden under another config section/ keyword (not called 'sessionstore', but '??thirdpartystore??' or what?) The following profile files are still handling a LOT of writes. I use Ancestry as example (the worst offender actually), but applies to other sites also.

.default-release\storage\default\https+++www.ancestry.com\ls\data.sqlite-journal ...
or occasionally
\https+++accounts.google.com ...

Just for these accesses, looking at 100k writes every second, like pulses. This is with only one window open and a static (no change) page. What changes on a genealogy page that requires updating every second = this is a list of dead people?? Finally, my question(s): What config sections and "keywords" handle these third party writes? Any clue/hint on how to eliminate?

Thanks

Until the most recent update, which came along with a Microsoft update, I was able to stream Peacock.com but now I'm getting an error message that my system configuration isn't compatible with Peacock. I have also had issues with YouTube, which keeps telling me that I have to disable adblockers - which I'm not running. I had another unrelated problem that I fixed by doing a system restore to before the Microsoft update, so there should be no issues with that end of things. It has to be Firefox because I can still stream Peacock on Microsoft Edge.

So, does ANYONE have any idea how I can fix this problem? I much prefer using Firefox to Edge and I don't use Chrome.

Thanks.
