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!

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?

Firefox has started hiding all tabs in a window except the active tab. This has happened in two different windows. I have no idea how to hide tabs and don't want to. How can I unhide the tabs. When I try to do it one by one, the first tab rehides when the 2nd one appears. Can I unhide multiple tabs at once? Do I have to unhide them one by one, and if so how? How do I stop Firefox from hiding tabs?

Hello,

I made a download 10 months ago, it failed OK.

But every other week that same old download keeps on restarting and failing.. its some kindof bug.

It then piles up with all failed downloads from the last year and they all try to load again and again automatically.

I tried to reinstall firefox and all but its a weird bug.

I have screenshots if needed.

Best regards

I followed the instructions at [[Unload inactive tabs to save system memory in Firefox|https://mzl.la/3AdRbLx]] but I still occasionally see the tab refresh when I select it. I start with a search on Bing, click an article to open a tab, follow links from there, back to the first tab and select another. I repeat this until there are several tabs open. Sometimes the page refreshes when I switch back to one that I previously reviewed. Is that controlled by the option browser.tabs.unloadOnLowMemory? if so, it doesn't appear to be working. [Edit] - The last time this happened I checked my system and found 10gig used of 64gig installed. I'm using the most current version of FF 120.0.1 on Windows 11 Pro v 22H2.

Dear FF/Mozilla:

I've experienced a number of issues where I'm unable to do banking transactions using the FF browser. In one case, Wells Fargo bill pay does not work (but works fine with MS Edge); in another case, an international money link payment to a vendor in the UK would not go through using Firefox (but did first time with MS Edge). In yet another case, Firefox won't load webpage photos for items for sale on the site www.telescope.com - the page loads with descriptions but photos would not load (I just tried it and, nada). This remains the case even after my VPN is disconnected.

I've used FF for several years now without too much trouble but with this ongoing non-functionality of FF, I'm tempted to migrate to MS Edge or a browser that is supported more widely.

Any help or advice? Thanks, Blaine

I recently installed Firefox version 120.0.1 on Linux Lite 6.6 and logged in to my Mozilla and Firefox accounts, then synced my data. In the past, when I used Ubuntu Desktop 22.04, this method would display all the bookmarks I had saved on other devices that also use Firefox. However, for this case, syncing did not successfully display bookmarks in the Firefox toolbar.

I then tried exporting bookmarks to an HTML file, then importing them into the newly installed Firefox using the Bookmarks Manager, but the window for selecting the HTML file did not open, so I couldn't import bookmarks.html into the new Firefox installed on Linux Lite 6.6. I also tried restoring from the Bookmarks Manager, but the window for selecting the HTML file did not open either.

Is there another way to transfer these bookmarks to the newly installed Firefox on Linux Lite?

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.

Dear Community,

Just like to ask how I could get Firefox to show a dark mode for all apps that I open, please? I know that changing the settings on Firefox to Dark makes the browser show only a dark mode. However, when I search for other sites, they show up as a white background. How can I change this, please?

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 all!

I am using Firefox Multi-Account containers with Firefox 120.0.1 (64-bit) and the New Outlook desktop client with Windows 10(*). I have more than one Office 365/Outlook account, so I use different containers for each account.

Whenever I click on any link in New Outlook, it opens in one of my Firefox containers rather than in a default No Container tab.

Unfortunately, it opens in a container where I am logged into a different Office365 account than the one I use for the desktop client. This means any Office or organisation-specific links fail to work unless I copy and paste the link across.

Is there some way to force Outlook to open these tabs as No Container?

I had Firefox 120.1 on a Windows 11 Pro 23H2 system and everything was fine, then today Firefox updated itself to version 122 and all my bookmarks / settings and saved passwords disappeared. When I went to the bookmark manager there were no backups to restore but when I searched the C: drive for "Bookmarks*.json*" I found dozens in the profile that Firefox is currently using (about:porfile shows my default and there is only one profile on the computer) and I copied the most recent one from a couple days ago and used the bookmark manager to restore it. However I've lost all my saved passwords and I absolutely need to get those back, how can I do that?
