Roughly every 2 weeks I backup important files to a external hard drive.

One of the things I always backup is my Firefox profile. I have been doing this for years without any problems.

I 7zip my profile and copy it to the hard drive.

I tried to do this yesterday (July 25 2025), and was getting access denied messages for files in the profile. So I tried to simply copy the profile. Same thing access denied.

I cleared the history, used wise disk cleaner, rebooted my machine and tried again. Same thing access denied when trying to backup or copy the profile.

I am assuming that this is happening since 141 because I updated Firefox since the last time I backed up my profile, and never had a problem previously.

Could anyone have an idea what the problem is? Thank you for your time.

It seems that scrolling periodically stops working, whenever I encounter nested scrolling on a page, eg. gemini.google.com with enabled canvas.

I scroll through the file, and then can't scroll through the conversation (However I can keep scrolling inside the file window). It usually starts working again in a few minutes.

Hi. News videos from www.bbc.com won't play. When I ask the BBC website to play a video, I get a blank area of my screen, with a play button. Clicking the button makes it go away, leaving me with just the blank area of the screen. Videos from youtube, movie trailers, etc play fine - it's just videos from a few sites (such as BBC) that yield nothing. I have autoplay videos disabled by default, but: I'm not trying to have the website autoplay; The setting doesn't affect other websites; and there's no way to disable autoplay for the website I'm on (no way I can find, at least).

It seems only whne playing a game at the moment but when you click the louse, it locks on and drags items everywhere and i have to click it several times to release, i know it must be firefox because i did try it on opera and don't get the same issue but i loathe that browser like the plague so would prefer to use this, would anyone have any idea please?

Hello Firefox team I was recently in Greece and now some pages appear in Greek. Like "eurobox - Αναζήτηση Google" upon a search. Windows 10, 64 bit, English. Firefox 141.0, 64 bit, English. I'm a Dane living in Germany, speak Danish, English & German, my computer is English. What to do to avoid this? Thanks. /Tom Gundtofte-Bruun, tom@g-b.dk ... Tried to upload a screenshot as .doc or .pdf, but that didn't work, sorry.

I have a Scotiabank account. Its login name is my CC or rather debit card number. I got a new card with a new number. FF will not let me change the old one to the new one. So I went through Safari and entered the new one by hand, which allowed me to do my online banking a day or two ago.

I want to use FF and to change the number, because FF is my default browser and I like it.

thanks, Shelly Errington sherring@ucsc.edu

Hi, I've seen others ask this same question in archived posts with no proper answer.

How do I select all tabs to be imported from a synced machine? I have the list on my sidebar, I can import or close one tab at a time, but there is no menu available to select them all (there are many). Right-clicking on the device name etc. does nothing.

Windows 11, Firefox 141.0

Many thanks for any help!

Hello, I have used Mozilla FireFox for some time now and thought restoring it to a new device using my account after a catastrophic laptop failure on July 12 would be the easiest of the recovery tasks I was going to have to pursue but apparently not. For a start, not all my passwords are available to me and then the look and feel of the browser is different. Where I had grouped tabs of bookmarked URLs the Bookmark bar has reverted to an older version with some bookmarks I had deleted and some newer ones missing. I'm not even able to reconstruct what I had working before and it's become very frustrating. Is there an older history/moment in time I can revert to? I've already been told that the VPN I have been subscribed to is not compatible with my new ARM-based device so my loyalty to Mozilla is being tested at this time. Thanks in advance for any insight you can provide.

Since this week's update of Firefox Developer edition when the browser is restarted tabs do not load until I reset the browser.

I suspect an add-on but have not been able to determine which one.

This is happening on multiple (3) physical computers.

I just started a new work role and haven't been able to find the time to troubleshooting of the issue myself.

This has been very disrupting and stressful.

I have a problem that I cannot resolve for months. I'm always listening to YouTube I'm listening music while I'm working or I'm doing task on Firefox I used to have no problem I just Open YouTube and let it play on auto play and it goes no matter what. About 6 months ago I started to experiment some problems the video stop all the time even if I have a playlist going on like 50 song one after another it will stop once in a while for no reason. It pissed me off so much that I have to change my browser by default and I don't like other browser I use always Firefox with DuckDuckGo so when I'm trap to use other browser I get mad the only one that functions very good it's on edge Microsoft and seriously I cannot stand this… I'm forced to use YouTube only on edge it's the only place that it works no matter what it never stop. It used to be a little arrow in the bottom of the screen, a button that you can click on and off to Auto play or not, this button disappear it's not even there no more. This button Auto Play it's not there in Edge or Google Chrome but YouTube works for them not for Firefox so what is the problem it's not the setting is it YouTube that's got problem with Firefox? I don't know, it must be a way, a back door because I need to go back with Firefox I need to go back with DuckDuckGo. I'm pissed because I have to leave just because of that and that it's no compromise for me my music will pass before everything else. I don't feel like asking question to the community because it takes months before they answer you if they do. It's no customer service for Firefox or Mozilla whatsoever they don't answer you they don't talk to you they don't fucking care and this is another thing that pisses me off because they have a good thing going on but they don't care about the people. This was, this is what I did so far: Disable Hardware Acceleration "Performance" section.

I unchecked "Use recommended performance settings."

I unchecked "Use hardware acceleration when available." Clear Cache and Cookies I cleared the cache and cookies preferences privacy: Under "Cookies and Site Data," I clicked on "Clear Data."

Extensions about:addons I disabled all extensions to see if the problem persists… nothing happen YouTube I used YouTube in a Private Window … nothing happen YouTube Playback Settings I changed the video quality … nothing happen

Developer Tools for Network Throttling Maby using the developer tools, I can check for network issues? I didn’t try yet Reset Firefox I Refresh Firefox to restore it to its default state… nothing happen I uninstalled it and clean the registry. I reinstalled it. …nothing happen I ensure that you I’m using the latest version of Firefox: Yes My laptop specifications: Device specifications Device name: Fatcatbasse Processor: AMD Ryzen 7 5800H with Radeon Graphics 3.20 GHz Installed RAM: 64.0 GB (63.4 GB usable) Device ID: 8EDED38D-1047-40B4-8AIF-C2361C5E5841 Product ID: 00330-80000-OOOOO-AA797 System type: 64-bit operating system, x64-based processor Pen and touch: No pen or touch input is available for this display

Graphics Drivers I ensure that my graphics drivers are up to date. They are Testing Other Browsers I already mentioned that Edge works well Google Chrome also. I'm trying to receive an answer from anyone on Firefox nobody answer me because nobody can answer this question. It's been months that I'm waiting. Thank you very much for your help. Thank you, Firefox.

Hi Mozilla Support,

I'm experiencing an issue when trying to open a specific page on my website in Firefox. The page URL is: 👉 https://ihop-menus.com/ihop-secret-menu/

It either loads very slowly or sometimes gets stuck on a blank screen. I’ve tested the same page on Chrome and Edge, and it loads normally there, so the issue seems to be specific to Firefox.

Could this be related to JavaScript rendering, caching, or some browser-specific incompatibility? I’ve cleared the cache, tried private mode, and disabled add-ons, but the issue persists.

Any insights or troubleshooting tips would be appreciated!

Thanks in advance.

Hello! I saw that the Test day event had started. In Firefox Beta, I entered messaging-system-action.testday in about:config, put it on a string and set the value to testday as it said in the instructions. When I restarted Firefox, the welcome window did not appear and there was also no letter S next to the search as it should be. Please help!

Thanks for the answers!

Firefox quite often will remove, replace, add, or layer text as I use it. It has been doing this since I first downloaded it, and I haven't had it for long. (I will say that it isn't the first program I've seen do this. the only other program I've seen do this is Zotero and Tor) I'm only asking here, because those other programs are less used. I'm not doing anything weird with it, it just happens as I use it. Some of the screenshots I've submitted are of what I'm literally typing right now.

I've tried using troubleshoot mode, but it works just fine when I'm using troubleshoot mode, so I can't appropriately use that mode.

Recently when I load FF, something is injecting what looks like a Yubi Key character string and DUck Duck Go searches for it on the net. I have no idea what is causing this. It happens without the Yubi Key being inserted so is obviously a stored set of strings. I tried clearing the cache and history, but it still happens. Also, for some reason I have to clear the history and cache very often or FF will time out trying to go to a new web page.

Anyone have any ideas?

System is I7 running Windows 11 pro 64. (kept updated) Avast Premium Security and Malwarebytes (both kept updated)

When I try to run firefox 141.0 (Linux x64) I get:

libxul.so: undefined symbol: gdk_wayland_device_get_wl_seat Couldn't load XPCOM.

Is there a way to fix this?

I'm using Slackware 14.2.
