I have had this issue for a couple weeks now with youtube. When running in a private tab it will frequently not accept input for something like 10 seconds at a time. Playback works totally fine, no real stuttering or lag in the video, but pressing pause will generally take significant time to actually pause. This is true of all other inputs including keyboard commands, clicking on links, right click, etc. It seems to have a rolling window where inputs are accepted because if I wait for clicking play to work I can also quickly change the volume or right click a link. It'll even accept the input if I'm in a different window (like if I hit play then click over to my second monitor). This doesn't seem to happen in a normal window, only private. All other firefox tabs work totally fine with none of this lag, nor do I see any other issues on my computer. I haven't noticed any spikes in hardware usage nor am I using anywhere near all of my PC's resources.

I'm only running 2 extensions I think would interfere here (ublock origin and enhancer for youtube) and I've tried running with them disabled to no effect. All my extensions are up to date, as are my browser and OS, this has persisted through restarts (though it seems to take some time to come into effect after a restart). I've tried disabling hardware acceleration and clearing the cache.

So yeah, no idea what's wrong. It's not like unusable, just really annoying. Thanks to anyone that helps.

Issue: When trying to stream video via criterion, progress spinner spins for about a minute and then the website delivers: 'Please try again in a supported browser'. Firefox delivers: 'Firefox is installing components necessary to reproduce the audio or video in this page. Try again later.'

In plug-in manager: Widevine is not enabled, receive alert: '...this will install in a few moments'. It does not actually ever install. In settings: Play content with DRM is enabled.

OS used: UBUNTU 22.04.02 LTS 64 bit

Attempted fixes: 1) Toggling DRM in settings. 2) Firefox & machine restart 3) update & upgrade terminal commands, separately 4) Changing VPN servers & disconnecting VPN (NORD)

Note: Playing videos on Youtube works, as does streaming music via Tidal.

In Firefox, one can drag'n'drop a tab to the bookmarks toolbar to create a bookmark. During the drag, If one hovers the pointer over a folder in the bookmarks toolbar, the folder is supposed to open so you can put the newly created bookmark inside the folder.

This behavior has been failing a lot for me lately: the folder doesn't open, so dropping the tab doesn't create a bookmark. - The behavior is erratic: right now it works for some tabs and fails for others; - Drag'n'drop to the bookmarks toolbar outside a folder still works; - Drag'n'drop to the bookmarks sidebar, inside a folder or not, still works.

NB: I'm pretty sure it's a bug, but I never created a Mozilla Bugzilla issue before so I decided to see what happens here first.

Browser: 122.0 (64-bit) OS: Ubuntu 22.04 LTS

I use a MacBook Pro. I recently created a new profile for Firefox (for work purposes) and set it as the default profile, because I'm trying to get off Chrome entirely. The preexisting no-longer-default profile contained all my "personal" data - bookmarks, extensions, etc. Continued using both profiles for about a week with no issues. Last night my MacBook updated and when I reopened Firefox, the new default profile was fine, but when I went into about:profiles and launched the secondary profile in a new browser, it was completely empty - no history, no bookmarks, no extensions, nothing. That's at least a year's worth of data completely gone. I've looked through support articles and past folks' questions and am just completely lost as to how to restore it or what went wrong. If it's not possible to restore that data, how can I at least prevent this from happening again? I've very much lost trust in Firefox profiles because of this. Help please?

Hi,

I was a former IT person for decades and used Firefox because I love it. But lately, it isn't usable for me. Seemingly happened out of nowhere within the past few weeks.

I tried all the troubleshooting steps in the guides on your support forum, but nothing worked. So I tried the following:

1. Uninstalled Firefox using Windows Uninstaller 2. Deleted every single Mozilla folder from within the user profile to the program files folders, local roaming folders, etc. - EVERYTHING. 3. Went into the Windows Registry and also deleted Mozilla folders within the local machine and current user folders. 4. Rebooted computer 5. Went to Getfirefox.com and reinstalled Firefox. 6. Logged into a brand spanking new Firefox installation

Still SLOW as molasses. Frustrating. I can't work. It is literally 4x slower than any other browser now. I use Firefox for 90% of my web stuff, the other browsers 10% of the time for testing. But as it goes now, I cannot use Firefox anymore after decades of using it.

Anything else I can try? Maybe I missed something when I scrubbed it and reinstalled? Why suddenly is it this slow? Any ideas?

I will try next to log into a different Windows profile I guess and see if that improves it. Maybe my Windows profile is jacked up, although, I thought removing all Mozilla folders from within my Windows profile would be enough, so I am not so sure that will fix it. I will try though.

Any help you can provide would be much appreciated.

Thanks,

Mark

Dear Ms, dear Mr, I experience the following problem with the user interface of my bank’s website when I consult it using my new MacBook Air laptop computer. The image displayed on the computer screen is apparently designed for a smartphone, not for a computer screen. This anomaly never occurred with my previous computer. And it does not occur at present when I work using Safari. So, I assume that it is linked to the navigator’s (i.e. !Firefox) configuration. This is the reason why I am contacting you. Please find below the characteristics of the new and old configuration. - New configuration, the one with which I have the problem: Model : MacBook Air 15“ M3 2024 Processor: Apple silicon M3 Operating system : Mac OS Sonoma 14.7.2 Navigator : Firefox 128.6.0esr (16bit) since 7 january 2025 - Old configuration : Model : MacBook Pro (13“, Mid 2012) Processor: 2,5 GHz Intel Core i5 Operating system : MacOS Mojave 10.4.6 Navigator : Firefox 115.18.0esr (16 bit) I would be happy if this frustrating though minor problem could be solved. Thank you for your assistance. Michel Stevens

Hi,

I have a laptop with an AMD Ryzen 7 8845HS CPU, including a Radeon 780M iGPU, running Ubuntu 24.04. In order to fully utilize the GPU by supporting OpenCL acceleration I installed the additional drivers by: `sudo amdgpu-install --usecase=graphics,multimedia,opencl --opencl=rocr --opengl=mesa`

After that programs which benefit from OpenCL acceleration recognize the GPU, however firefox starts crashing with the following error msg:

XPCOMGlueLoad error for file /usr/lib/firefox/libmozgtk.so: libwayland-client.so.0: failed to map segment from shared object Couldn't load XPCOM.

It seems that the AMD GPU drivers registered their libraries in `/etc/ld.so.conf.d` as 10-rocm-opencl.conf, 20-amdgpu.conf which means that libraries within the given folders are found first.

This applies to the libwayland-client library, which is used by `/usr/lib/firefox/libmozgtk.s`:

ldd /usr/lib/firefox/libmozgtk.so | grep amd libwayland-client.so.0 => /opt/amdgpu/lib/x86_64-linux-gnu/libwayland-client.so.0 (0x00007013767bf000)

Interestingly the same `libmozgtk.so` library is used by thunderbird:

ldd /usr/lib/thunderbird/libmozgtk.so | rg -i amd libwayland-client.so.0 => /opt/amdgpu/lib/x86_64-linux-gnu/libwayland-client.so.0 (0x00007d44b0f41000)

However thunderbird just works fine, so I expect that there might be something wrong with firefox utilizing this library.

Maybe I should also mention, that I'm not even using wayland as desktop compositor, but good old x11:

echo $XDG_SESSION_TYPE x11

Is there any way to further debug this issue?

Hi,

more Details concerning the problem you can see here ! It should be great if you could help us with some diagnostics, for example why the problem only appears with FF on Linux, not with FF on WIN.

STR:

1. Launch Linux FF
2. Visit this page "Potential issue with plugin PITM" (Preview here
3. Because you will need an Account for visiting account please follow "Konto eröffnen" (Create Account) instructions).
4. After my approval for the account please visit again "Potential issue with plugin PITM"
5. Click "1.png" Below heading "Attachments", that should work without problems.
6. Close image view
7. Move Mouse pointer to image below heading "My test with a screenshot" – should become magnifier
8. Now Click that image

  » Expected (and so it does with WIN): Big image opens in new TAB
  » Actual:  New TAB opens, but without image view.

What are your results? FF Linux Problem or something else?

Hi, It is not a question but a bug report. From the version 131 up today the Nightly stopped to initialize quickly as before. Certainly, it is not the windows 10 21H2, the antivirus, the firewall or anything other similar internal problem, just because the Edge and the Opera are working fine and they are four times more rapid than the Nightly. It is just to say, that your procedures to improve the security is transforming the Firefox in a mirror of the usefulness Chrome. I take the time to open the home page of Firefox = 9 seconds, against 0.28 s of the Opera. So, I think you should rethink the security and other hidden setting options of the Nightly, because as is, it is very bad. The big thing that the Geeks from silicon Valley did not have in mind is: There are lot of people that need to find extremely fast a configuration, like to export/import passwords from older browsers, or computers, without need to replace one by one. There are many other things that you decided to hide, but I don't know why. Anyway, I will try to update one more time, then, unfortunately I could not use the Firefox anymore. Further, I want a few add-ons, either if there is any percentage of insecurity. A few times we need afford risks to understand and discovery other problems in the web. We cannot do it anymore with the Nightly.

Hi,

I am encountering an issue where Firefox throws an "Uncaught out of memory" error in the console, despite my system having ample RAM available. Here are the details of the problem:

• Error Message in Console: Uncaught out of memory
• Memory Usage Observed: Using about:processes, I noticed that Firefox's maximum memory usage caps at around 7GB.
• System Specifications: The machine running Firefox has 128GB of RAM, so there should be plenty of memory available.
• Firefox Version: 126.0a1

Given the significant amount of RAM available on my machine, it seems unusual that Firefox would hit a memory limit at just 7GB. I suspect there might be a bug or a misconfiguration causing this issue.

Can you please assist in diagnosing and resolving this problem? Are there any settings or configurations I should adjust, or is this a known issue with the current version of Firefox?

Thank you for your help.

Secure connection failed and Firefox did not connect Firefox Last updated: 01/16/2024 39% of users voted this helpful

This article explains why you may see a Secure Connection Failed or a Did Not Connect: Potential Security Issue error page, and what you can do.

   If you see a Warning: Potential Security Risk Ahead error page, see What do the security warning codes mean? and How to troubleshoot security error codes on secure websites.
   To troubleshoot other error messages, see Websites don't load - troubleshoot and fix error messages.

Secure connection cannot be established

When a website that requires a secure (HTTPS) connection tries to secure communication with your computer, Firefox cross-checks this attempt to make sure that the website certificate and the connection method are actually secure. If Firefox cannot establish a secure connection, it will display a Secure Connection Failed or Did Not Connect: Potential Security Issue error page. Secure Connection Failed

A Secure Connection Failed error page will include a description of the error and a Try Again button. There is no option to add a security exception to bypass this type of error.

Fx97SecureConnectionFailed ~~~ The url gives me this can you help please its not bitdefender total security blocking it I dont think https://support.mozilla.org/en-US/kb/secure-connection-failed-firefox-did-not-connect?as=u&utm_source=inproduct

I installed one of the ad blockers, I can't remember which one. It's given me so much trouble that I thought to disable or delete it. I deleted the little icon ( a stop sign) that shows up on the far right of one of the menu bars (don't know the name of that bar but here it's the second one down). But websites still complain that I have an ad blocker. I've gone to 'add-ons and themes' but I can't find it. BTW, what's the difference between an add-on, a plug-in and an extension? Which one of those are ad blockers? How can I see and then delete whichever blocker I still have? Without the icon I can't even disable it for individual sites.

For some whatever-reasons (TLDR; I need to see the whole domain (including subdomains) clearly, unlike the default of only highlighting the TLD&second-level domains[1]) I want to disable the color-distinction which highlights TLD and second level domains.[2] Is there config to do so? If not where should I propose one?

Thanks.

[1]: for example ko.wikipedia.org and en.wikipedia.org will have wikipedia.org highlighted, and that's what I can't accept because ko.wikipedia.org (Korean) and en.wikipedia.org (English) is completely different site. (Some might say you can distinguish by language, but there are some English sites which shares the same domain on wikimedia.org, so you get the point here.) [2]: From the screenshot you can see only `wikipedia.org` is highlighted. I want to make it highlight all of en.wikipedia.org. (If I need to highlight everything including the site path below the TLD, I can accept that.)

I'm running version 118.02.2 (64-bit) of Firefox on Windows 12. I *always* have the 'Open previous windows and tabs' checked. Starting yesterday, Firefox opens with nothing other than a blank page. Luckily for me, this has happened in the past and I have a Bookmarks Menu folder with my default tabs saved. Even so, it's still frustrating.

EDIT: Of course, moments after I posted this I discovered the solution - uBlock Origin was preventing the images from displaying properly. Please feel free to close/delete this question.

Hi Firefox community,

I'm looking for some help troubleshooting display problems with one specific website. (I've had no other issues like this with any other webpage.) This website is a log that we use at work to track cases.

The first screenshot is what the webpage is supposed to look like when displayed properly (loads properly in Internet Explorer). The second screenshot is what I see when I try to access the page on Firefox. I've also found that the links in the buttons don't work either.

A couple of things I've already tried based on forum suggestions that haven't fixed it: - Refreshed/reloaded the page - Deleted cookies/cache - Updated Firefox (currently version 119.0) - Reset Zoom, minimum font size, page style, checked that Javascript was enabled, unchecked hardware acceleration - Turned off Enhanced Tracking Protection, verified that Firefox wasn't blocking parts of the page through the padlock icon next to the address bar - Restarted my laptop after all of this (using Windows 11 on Dell XPS 15)

Any suggestions or advice is greatly appreciated. It's not the end of the world if I can't fix it but it's just a bizarre error and I'd prefer to not open Internet Explorer every time I have to use this website.

Thank you!

First, I tried to install via the web download from mozilla.org. That led to the wont-start-up problem. Then I reinstalled and reset my computer, and had the same problem. Then I uninstalled and reinstalled via the microsoft store, and that worked fine, and got my browser set up. That was all yesterday. Today, I tried to open firefox, and it once again wouldn't start. I'm pretty sure I shut down my computer overnight between yesterday and today. So, I uninstalled and reinstalled via the microsoft store. Here's the *really* weird part: today, when trying to launch firefox, windows will instead open a different program, seemingly at random. When launching firefox, it has instead launched:

• Audacity
• Some AMD software thing
• Calculator
• Microsoft office

It won't open even if I try to open it in troubleshoot mode. I tried to find the crash logs file in my system that some support article recommended I find, and windows couldn't find that file. No error message or dialogue box appears when firefox crashes on start. I'm running windows 11 on an amd gpu and cpu. Help me not use google anymore!

Using new computer and Firefox settings synced from previous computer. Two major issues started when using the new computer: When opening links in new tab (manually by right-click link and chose option to open in new Tab) nothing happens. The URL appears in the tab address line but the web page doesn't load. Pressing enter doesn't fix it. Copying URL and opening new tab, and pasting URL, doesn't load the page either. This can occur when first open Firefox, or can be after some time.

The other issue is Gmail often showing "Not connected." and retrying. The computer is connected to the internet, and can access web pages in other windows in Firefox, or in Chrome. Google apps, such as Keep, also exhibit unable to connect to Google. Have to close Firefox to fix this and can often return shortly after signing into Gmail again.

Have tried disabling extensions and add-ons, resetting preferences and tab settings, clearing temp files and cookies, resetting Firefox, uninstalling Firefox and re-installing. All to no avail.

The previous computer doesn't have these issues.

I have Startparge set as my default search engine. I used to type directly into the address bar (see first image).

Press Enter, and the Startpage results page for this search phrase would show up. Somehow, this has now changed. I press Enter, but the result is just the Startpage home page, with a blank search box (see second image). So I then have to type the same phrase in again in Startpage's own box. This just trips me up.

The crazy thing is that this only happens sometimes - but more often than not. I haven't seen it work right for weeks: I just did it now to make screenshots, and it worked wrong. I just did it again and it worked as expected: pressing Enter took me to Startpage's results.

Any clues how to change settings to fix this?

So, I don't have an issue, I just want to scream because my firefox crashed and when I started it back up it asked me about booting it in safe mode or something, but I didn't want that and the other option was 'refresh firefox'

Nowhere AT ALL does it warn you that it will WIPE your current installation and RESET everything. I had no ideas and had not saved up the content of my OneTab extension in a while, FUCKING THANK YOU FOR THAT.

That's it. Fuck you.

I'm using Firefox 126.0.1 (64-bit) in Windows 11. I needed to download two files named index.html (in different source directories) from my company's content management system. Both got downloaded as index.htm. They were the right files... only the extension was changed.

I spoke to the person who maintains the content management system. They tested it and said it's not doing that, must be the browser.

That sounds fantastic to me, but I looked through the support messages here and found several about files whose extensions were changed on download; for example from .loa to .mp3. No explanations or workarounds, though.

Can anyone shed light on this?
