Hi everyone

I used Refresh Firefox option and it created "Old Firefox Data" folder on my desktop.

Awesome stuff. Sadly I cant get rid of it, here is why:

1. At first it said that the folder is used by another program and I cant delete it because of that. Cool, I decided to uninstall Firefox and make a clean install, so I have space to delete the folder too.

2. Long story short, it didnt work. I removed Firefox and tried to delete that folder, but wait for it, yeah I cant because I need permission from MYSELF. Awesome stuff.

3. I decided to use safe mode, so I used run command to run msconfig and I changed it to boot in to safe mode. But wait for it! YES! Its bugged and I cant login in safe mode, because pin is useless and it doesnt give me option to use password, so after hour of various things I got back to my normal mode via CMD commands. THANK YOU MICROSOFT.

4. So now Im stuck with the lovely "Old Firefox Data" folder, which cant be removed normally, neither in safe mode and wait for it! NEITHER WITH ADMIN CMD, not even the takeown /f "Old Firefox Data" /r command. THANK YOU MOZILLA!

So is there someone knowledgeable enough to help me to get rid of that folder pretty please? Like really a lot please.

I have lost my tabs after the recent update. They used to show all tab groups in toolbar icon as mentioned here (https://support.mozilla.org/en-US/kb/tab-groups) in manage tabs section. Only the groups that were open are retained, the groups which were closed are lost. They contained important tabs which I haven't bookmarked. I didn't see any policy of removal of inactive tab groups after certain time, any help would be really appreciated. I use the desktop app on Linux.

Good evening Mozilla,

Well I am facing an issue, no sound coming from any website like netflix or youtube or prime from mozilla browser.

Could you please fix it for me.

Regards

I got a new PC and tried to sign in to my FireFox account to synchronize. But, foolishly, I ended up resetting my password! Don't know why did that, as I was able to locate my password stored elsewhere. I think this action erased all my data in my online profile & I cannot access my account data (bookmarks, user IDs & passwords) online.

Since my data was still in my old PC, I followed the directions for finding my Profile folder. I copied the folder contents to the Profile folder in the new PC. This has not worked.

I realize I wasn't supposed to copy the entire folder contents, which could be the reason why it's not working. Also, the profile folder contained a large amount of data (3 G). So, it's possible that not all files have been transferred correctly.

Please help me!

Thank you very much! Madoka

Dark mode in Firefox has broken just now. The issue appears restricted to Firefox - all other elements in environment (Ubuntu/Cinnamon) appear to be operating correctly.

The elements at the top of the screen and some menu screens are now white rather than dark grey. Due to a neurological condition this causes near-instantaneous cluster migraines.

Is there a way I can fix this? Is there a way you can fix this? Is there a way to access the web without a browser? (eg through the text terminal)

In May 2025 all browsers should have removed the default styling for the h1 element when it is nested in a sectioning element (article, aside, nav, section). I went into Firefox Dev Editions user-agent style sheet and noticed that the styling for nested h1 elements is still the same. I'm wondering why that is the case, since I was under the impression that all the major browsers had completed make the necessary adjustments at the end of May 2025.

I am on Linux Mint 21.2, and I just updated Firefox (141.0). Now, the bookmarks bar, toolbar, and the tabs (everything above the displayed page), as well as the menu, bookmarks menu, and sidebar, are in light mode even though I have dark mode set (They were dark before the update). I tried playing with the Dark Mode settings to no avail. My system is set to dark mode in general. Are others experiencing this? Is there some sort of fix?

I am aware, there are far more serious issues on our hands, but someone please fix this naming on the FTP server?

Idk maybe adding enough zeroes to make the release number 8 or 10 digits long.

0000000005 instead 5 0000000028 instead 28 0000000077 instead 77 0000000131 instead 131

The current order is like 131, 28, 77, 8.

I kept my installation of Windows 11 while doing a clean install of Windows 11 to another drive. I installed FF and copied the profile from the old installation to the new one. about:addons displays all my add-ons and they're all enabled. But their icons don't appear to the right of the search bar. How do I get them back?

Hello, I just used the Firefox 141.0 (aarch64) wizard for Raspberry Pi OS 1.0, to import bookmarks from Brave, however the wizard said 0 bookmarks imported.

I also manually exported and imported the bookmarks.html file and the latest bookmarks aren't appearing at the top. It seems the bookmarks are nested in some bookmarks directory by default. I'm confused?

Also I tried a manual import several months ago but same issue about some strange nesting structure rather than simply appearing at the top. Now I'm really confused and worried I'll lose my bookmarks as there's about 3 version in various nested structures. Please help just make an easy move to Firefox.

Firefox has started redirecting to advertising pages after clicking on a link. Only on 1 site. The site loads but not quite correctly. Normally has information about movie ratings show up when you hover over pictures. Have to double click (double load) to get where you want. Does not do it with Edge. Used to work fine, just started.

I have two Mac systems, a 2018 Intel Mac Mini, and an M1 2020 MacBook Pro, both running Sonoma 14.7.6. On the Mac Mini, Firefox opens to the familar "Recommended Stories". On the MacBook Pro Firefox opens to a long list of items I'm not the least bit interested in. How do I get the MacBook Pro back to nothing but the "Recommended Stories"? I don't want/need NHL, NFL, NBA,Television, MLB, Pro Soccer, Education, Food, Health, Parenting, etc., etc., etc.

I have a desktop and a laptop on firefox. I am selling my laptop so i cleared history and deleted all bookmark history.

To my horror, even though i remember i have signed out of mozilla account on the laptop firefox, on my desktop firefox all the bookmarks including bookmark folders are gone. Thankfully, i have a fairly recent backup of firefox userprofile file so i restored them.

However, to my horror once more time, I realize now firefox sync automatically deletes my bookmarks everytime it syncs so i have to turn it off.

How can i make firefox sync to treat my current bookmarks as the latest and stop deleting them?

When I select Dark Theme, I DON'T wanr to see this. I just noticed this on my Linux Mint desktop machine tonight when I logged in. I also have Dark Reader installed and it isn't affecting ioit eitherit either. Make this go away. It burnsssssss!

While using Facebook, I changed some Meta setting to block ads, then unblocked it. After this, Firefox does not show any Facebook info. Switching to Edge, everything shows as normal. Can't see any setting on the Firefox settings page that controls this.
