A folder appeared on my desktop titled "Old Firefox Data". It is dated 11/2/25 at 12:47 PM. What is this and why did it just appear on my desktop? Do I need to keep it or can it be deleted?

When I opened my computer this morning, it said Firefox crashed. Yesterday, I was scammed by a scammer claiming to be from Microsoft who had me do many things on my computer to remove a virus that wasn't there. Instead, I suspect he may have access to my information now. So this morning after it said that Firefox had crashed, I asked to open a new Firefox session and things seemed to be normal. Please double check to make sure there is nothing wrong with my Firefox account and let me know. Thank You!

After having upgraded my W11 system to 25H2, I cannot install any extension. Installation terminates with "... something may be broken". I'm using FF 144.0,2. FF is used in more than one account alternatively.

On a second system, with less security measures, I have no problems.

I am using the new profile switching feature in the UI, from top of the hamburger menu. Firefox is my default browser on Windows.

Now, I want all links I activate from other Windows programs to open in a specific profile. I use the other profiles for auxilary tasks.

Is there any way to achieve this?

Every once in a while, my pinned tabs and/or my tab groups disappear. this usually happens after an update, but not always. Sometimes I type a lot of commands, and FF seems to get upset and freezes or goes black. I restart and poof, they're gone. I made a screenshot of my standard pinned tabs so I can restore it from that, which is a nuisance in itself. But the tab groups are gone forever along with the urls I painstakingly researched. I read the answers to two previous queries along these lines, both of which gave extensive, tedious procedures to recover them. I'm not willing to go through all that just to use Firefox. I've switched my tab groups to Edge just to keep them safe and although I prefer not to be captured by Google or Microsoft, am thinking about just switching to either of them.

Over the last couple of updates, FF has seemed less and less stable. I tried the vertical tabs and liked them but the open sidebar on hover stopped working and when the sidebar itself got stuck on open it hid the history and AI sidebars. Plus FF was very slow to open. I reverted to horizontal tabs and now it's faster but still the pins and tab group problems persist.

I'm using it on an HP desktop in Windows 11. Sorry I don't have any screenshots.

hello - since yesterday, the links on the startpage don't show anymore, even though they were perfectly fine the day before yesterday, when I shut down the laptop.

i can't find where I could change anything, since in the settings, the 4 lines are still activated, nothing has changed except they're suddenly not showing anymore.... ?

what can I do???

I did try to search through the articles, didn't see anything that could help me.

I would even save them and open a new profile if there's no way to fix it, if only I could find where those links on the startpage are stored...

thanks for helping.

Hello Firefox Community,

I’m facing an issue with my restaurant-related website Bojangles Menu with Prices—https://bojanglesmenuprices.us. .

When I search for my website in Firefox or share one of its pages through the browser (for example, by copying the link or sharing via email/social media), the preview doesn’t display correctly. Sometimes the image thumbnail is missing, and other times the meta title or description doesn’t appear.

Here’s what I’ve already tried:

Checked the Open Graph (OG) and meta tags on my site.

Cleared Firefox cache and cookies.

Verified that the site preview works fine on Chrome and Edge.

Updated all social and sharing metadata in my HTML.

Is there any Firefox-specific issue or setting that could affect how link previews or shared content are displayed? I’d really appreciate any help on how to make my Bojangles Menu website show up correctly when searched or shared via Firefox.

Thank you! Sonia

Hello, I reset my PC yesterday.

I didn't know my Firefox password anymore and clicked "Forgot password."

Then I created a new one.

Now my saved online pages and everything else are gone. So synchronization isn't working.

I have an account recovery key.

Will that work? And how?

Please help me.

Regards, Daniel

THE ABOVE ERROR MESSAGE HAS PREVENTED ME FROM ACCESSING 3 WEBSITES - PaddyPower, Ladbrokes, & UK National Lottery. None of the suggested remedies has had any effect. Can you fix it?

Went to bed last night & firefox was fine.

Opened it this morning & I don't see my bookmarks. The folders on the toolbar from Africa to Healthcare all say empty. Lottery thru web cameras have links in them that I can see. I I open another tab & go to google, then save that bookmark in the google folder it won't let me yet edit bookmark shows.

If I click edit bookmark it tells me that it's in the google folder already yet when I click on the folder, it says empty..

Ran a virus scan. It was clean. I tried restoring bookmarks from a previous day. Firefox was unable to do it.

What is going on? If the bookmarks are there, why can't I see them?

I've used this browser for years without a problem. Now all the sudden it's one problem after another. I'm ready to jump ship to a different browser.

I'm on version 144.0.2 (64-bit) using Windows 11 Pro.

I really enjoy the new sidebar revamp, but I've had an issue with it recently that I haven't been able to find a solution for. Typically, the settings gear is supposed to be situated near the bottom of bar. However, as demonstrated in the attached image, it is at the top near the bookmarks and history buttons. I have tried reinstalling the browser from scratch, turning the sidebar on and off, turning vertical tabs on and off, and even getting rid of my custom CSS theme for a time. None of these have worked. If anyone knows what the root of this issue is, I'd really appreciate the help.
