My Firefox settings are configured to "Open previous windows and tabs" on Startup. This worked fine until this morning, when I lost all of the tabs in my session, including the pinned ones. The last time I closed Firefox, there was only one window open.

I have already tried these ideas to restore the tabs:

• CTRL+SHIFT+T: Does nothing
• CTRL+SHIFT+N: Does nothing
• Three bar menu -> History -> Recently closed tabs: The list is empty
• Three bar menu -> History -> Recently closed windows: The option is greyed out
• Three bar menu -> History -> Restore previous session: The option does not exist in the menu
• Open user profile folder and open sessionstore-backups folder: There are three files named "previous.jsonlz4", "recovery.baklz4" and "recovery.baklz4". They are each 2KB and contain only an empty tab with the URL "about:home". There are three additional files starting with "upgrade" but they are from too long ago, so they don't contain the tabs I require.

The contents of these tabs are vitally important for my work, so this is causing me significant stress. If anyone can suggest ways to recover my previous tab beyond the documented fixes, I would greatly appreciate it. Thank you so much to anyone who can help!

It appeared a few weeks ago. Now, when I load google map webpage, the map loads normally with all the street, country, road names, then 1 second later, all those texts disappear. I've disabled all Plugins, delete cache, load a brand new profile, without effects. Note that if I use a user agent switcher plugin and choose any Mobile versions (but not a desktop version), the names load (and stay) normally.

Thanks!

I have both speakers and a headset on my desktop. The system has worked fine for the past 1.5 years. Suddenly today, when I unplug by headset and select speakers for audio, it works for other apps, but not on Firefox browser. Can someone offer some possible reasons for that and, even better, as solution?

CVE-2024-4367 has been announced several days now with MITRE and CIS. There is also an issue/advisory on the github repo for PDF.js which appears that the fix has been merged into the master commit of PDF.js (https://github.com/advisories/GHSA-wgrm-67xf-hhpq).

The vulnerability is pretty serious and yet there is no Security Advisory from Mozilla on affected versions, etc. (https://www.mozilla.org/en-US/security/advisories/)

Is this normal and I am just being impatient?

I haven't been able to login with MFA on my uni website and also make purchases using credit cards on commercial sites.

I have tried Troubleshooting mode and the problem persists. Switching to Opera browser showed normal functionality.

Firefox 125.0.3 (64-bit) on macOS 14.4

I have Mac, Windows, and Linux boxes. All show connected to Firefox Sync, however, bookmarks etc are only actually in sync between Windows and Linux. I've tried logging out on all devices, resetting passwords, reinstalling FF on the Mac. Can't seem to get it to work.

I made a private homepage years ago made up entirely of links to web-based AND local folders and files that are grouped into columns of categories like banking, medical, insurance, budget, etc. I keep it off-line on my desktop. I wrote the code so I could place an external link to a bank for example, next to a local link to the folder on my computer where I download statement pdfs from that bank and other bank files. The web page links displays: MY BANK Chkng/Debit Statements Credit Card Statements Bank Information The top link goes to the bank web page on line while the three lower links open folders on my computer where I save pdfs, txt, images, etc from the bank. Firefox opens the folders as "Index of file:///C:(folder path).

My personal home page is laid out with groupings like this for all sorts of information and associated web links: broker, vendor invoices, medical test, taxes, social security, health insurance, subscriptions etc. Today we get .pdf files with all sorts of information and no help organizing it for easy access. The Firefox browser has become the perfect tool for me. But I learned HTML coding years ago! Not so easy to do for others.

Today, many entities have on-line access that provides downloads like invoices, test results, payments, subscriptions, and much more that replace paper. Creating folders to hold these documents with their own local links on your web/local homepage makes sense to me.

While you can use "File" on Firefox to open a local folder or individual file, you cannot save it as a link. However, you can copy the path and transfer that to an a href=" line of link code in your homepage and build on that method. It's amazing how many types of files can be displayed in a browser that are locally stored. Even a link to a spreadsheet file will open that spreadsheets application. Having a varied list of links with quick access is worth the code-writing time. I wish there was an app to help anyone make their own custom folders and links to the contents in a "my homepage.html" . Is there a product idea in there for you folks?

When I'm sending attachments in Thunderbird some of my clients are recieving the email but not the attachments, though when they look on the phone they can see the attachment ?

What can I change in my outsettings for attachments to solve this issue

Hi, first the last update tried a few times over some days to install. Never got confirmation that it has been installed successfully. When I go to "About Firefox" I'm getting the information that I'm using the latest version.

Now I have problems, mainly when using facebook (especially when I try to play games through facebook) that Firefox uses enormous amounts of CPU and Memory. This does not happen all the time but at least in 70% of tries. I attached 2 screenshots

If this happens I'm not able to close Firefox the normal way but have to kill the process in the task manager.

Any quick help would be appreciated. I would also like to know if I'm the only one experiencing this or if it's a common problem.
