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.

If I don't use the custom adjustments in my Chrome css, seven buttons on that right side of the menubar are hidden, including the min-max close buttons.

This is problematic when I'm troubleshooting Firefox, and the css is disabled. If I want to close or take the browser out of max mode, I must move those buttons to the navbar, which has no such restriction accommodating those buttons, not to mention why is it necessary for that min-max close trio to monopolize 20% of the menubar. Waste of space. Inefficient.

I'm also curious why must that frame at the top of this sites pages remains persistent, and follows the user down the page, so that when you're composing, and accidentally (and all to often) touch one of those links, it get superimposed over the message, and you must move the cursor to the bottom of the page get rid of it. Not to mention, that frame shrinks the working area of the page about 30% vertically.

I mean, once you have already navigated to the destination page, and you're composing, how often/likely are you going to need to access that area?

Something has happened to my Firefox Browser and I cannot open Outlook which I have been using for years?

The Dialog Box says I need Windows 10, but I have had windows 10 installed, ever since it came out?

I'm trying to make some changes to the Firefox homepage through userChrome.css, but no changes are being applied.

I have set `toolkit.legacyUserProfileCustomizations.stylesheets` to true and my `chrome` folder is saved in the correct filepath: `AppData\Roaming\Mozilla\Firefox\Profiles\94fnqz8w.default-release\chrome`, so I'm not sure what could be causing the issue.

I've changed the code to just include one big change to see if it's working, though nothing seems to have changed:

``` .logo-and-wordmark { min-width: 100px !important; } ```

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.

I accidentally uninstalled firefox on my phone. it was the only login i had for my account/profile and unfortunately could not find my recovery key or old password. I reset it (same device, with 2fa) however it said that it could not recover my data. no passwords, no bookmarks.

Is there any possible way to recover my password through mozilla I also have an ssd from a laptop with a login and iirc passwords. Could I use that? thank you.

I want to prevent a specific website from coming up as an autofill/suggestion in the search/address bar in Firefox. I keep looking all over the internet for help with this, but everything keeps saying that I need to click the three-dot menu on the suggestion when it comes up, and there is no such three-dot menu at all for me.

I do not want to completely clear all of the autofill/suggestions in the search/address bar, I specifically transferred all of that stuff over from Chrome because it makes things a lot easier. I just want to block this one specific website from coming up in this way.

Before anyone asks, no, I do not have this website (or any page from it) bookmarked. I have gone into the 'manage history' menu and selected "forget about this site" for it, and this has not removed it from the autofill/suggest.

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.

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.

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.

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'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!
