Firefox Community Forum

I develop wordpress websites on FF Dev Ed on a Mac running macOS12.7.4. This current problem is one I've never seen before.

• In a regular window of FFDE, dropdown items on the menu, don't drop down.
• A youtube video, visible in the source and in the editor, doesn't display on the page.
• A gallery of logos doesn't appear on the page, though it does in the editor and the editor's preview.

These problems DON'T APPEAR

• in a private window,
• in vanilla Firefox,
• in another user account, using FFDE
• on other websites, using FFDE
• in other browsers,
• on other computers, using FFDE

In all those cases, site works perfectly. Actions:

• refreshed the page (dozens of times),
• cleared the site cache, the browser cache (Managed the data AND cleared the data)
• turned off all extensions,
• put the browser in troubleshooting mode,

all with no change. Although I don't think anyone else will see the problem, the site is https://homeopathyschool.org What am I missing?

Outlook.office.com not refreshing automatically anymore and requires browser refresh to show new e-mails, etc... Works in Edge and Chrome just fine. Had this issue years ago and issue self-resolved, so unsure what resolution was then.

Hello everyone, I am experiencing this issue since - I suppose - Firefox Sync existed. My main machine has - like any other machine I own - Firefox always up to date and a set of plugins like No-Script, an ad-blocker, a theme, GUI icon disposition and whatnot. When I install Firefox on a new device or machine and then proceed to sync them, I lost the theme across all my synced devices, ALL of the registered sites I have trained No-Script and the adblocker not to block and my GUI settings. In short every new machine with a fresh install and sync of Firefox will wipe and overwrite to its defaults any synced custom configuration I have. Is there a solution for this?

Thank you.

I am getting the following error after updating my Firefox installation: XULRunner This profile was last used with a newer version of this application. Please create a new profile.

I have tried creating a new profile and deleting the old ones, restarting Firefox, and even uninstalling Firefox and reinstalling it. The error still persists.

How can I get the error to quit popping up every time I open Firefox?

Hi

My GF just rung up, she is running FF 128.0 (64-bit) from Ubuntu snap on Ubuntu Linux 22.04.4 LTS (which I set up for her and use myself)

She complained that whenever she starts up FF she gets a display about "MS Windows Defender" and ringing some allegedly Microsoft number together with a recorded message over and over.

I logged into her machine remotely using the SSH connection I've set up (Fiewalled so only I can do it), killed FF and she tried it again with the same result.

I told her go go onto Chrome for now, which she did without incident. On no account should she ring the number, which is obviously that of a scammer, although they would be confused by a Linux system.

In the meantime I had a look round the files on her machine. I couldn't find anything in particular, but I wasn't very sure where to look.

I tried deleting the contents of .cache/mozilla/firefox/0e35ujgr.default/startupCache and that enabled her to use FF again but I notice it got repopulated, seemingly with stuff relevant to Windows - however I see that exists on my system.

She almost exclusively uses Facebook on the system, I wonder if it is malware from a FB ad?

Has anyone got any idea about what this malware is, where it came from and what files I should remove from her system if it happens again.

On occasion, eBay styling breaks, leaving me with plain unstyled HTML. Photo below for example.

This doesn't happen everytime, and it happens randomly. But once it has happened once there's no good way of fixing it, and I often have to swap browser.

There have been a number of questions about this on support.mozilla, but all are archived. One of the suggested solutions is to disable tracking protection for the site, on the premise that eBay's tracking files are mixed in with their styling files, but disabling tracking protection does not fix the problem.

I'm using FF 128.0 on macOS Sonoma 14.5.

For me, the solution was to disable the disconnect.me browser extension.

Hi. I am asking for help: how to protect with a password (preferably master) any access to the browser (and not only to logins), where there is simultaneous synchronization between several devices. Currently it works like this: I run FF, a popup appears for entering the password. I do not enter the password, I close the popup with "x". And thus I have access to everything that was previously open in the browser (in the previous session). If the user was logged in, I also have access to it. And I would like the use of "x", failure to enter a password, or entering an incorrect one to result in, for example, closing FF. So that there is no access to FF content

Thank you in advance for your help

Setup: Laptop with integrated Intel UHD 630, dedicated Nvidia RTX 2060 External Monitor connected via USB-C -> rendered through Nvidia card

Issue: Yesterday i disabled my laptop display in the windows settings as i only need my monitor. This resulted in laggish scrolling behaviour in Firefox. Not always but mostly a delay of ~100-300ms. Scrolling up/down fast doesn't really scroll, it just jumps with said delay. It happens on touchpad or mouse (mx master s3). If i enable the main display (extended) everything is fine.

Checked so far:

• All input-related add-ons, apps (Logi Options+, xmouse button control, ...) are disabled or off
• A reset or reinstall of Firefox doesn't help
• Drivers are up to date
• Changing the graphics performance preference (accelerated, energy saving) in the windows settings doesn't effect the behaviour
• Smooth Scrolling is off

Any idea what's the matter?

Hello there.

After updating, Firefox, once more, lost all my open tabs and history. Extension icons have become invisible on the toolbar even if i unpin and pin them again. Thanks to the extension "Tab Session Manager", I was able to retrieve the json file of my last session but the crazy part is that pages are not loading anymore! Even if I type google.com in the address bar, it just seems to load forever and nothing happens. I have been using Firefox as my main browser for years but this is the second time it happens in about 1 month and I am about to ditch Firefox for good if I can't fix this. Can't afford to lose data like that... Last time it took me a hell of a long time to fix it. This time, pages aren't even loading, except it seems, for the support pages...

Installed extensions: Tab Session Manager, UBlock Origin, Privacy badger, Phantom, Metamask (lost all the wallets data and setup), NordVPN, other crypto wallets...

As the title states, I have been testing out web push with a project I have in mind and am running into the issue that on firefox after making a request to send a web push, it takes a few minutes before firefox acknowledges that it got it and shows it. Afterwards, web pushes are shown instantly until again after being inactive for some time (not really know to me) it is delayed again in receiving web pushes. On chrome, they are received instantly every time. I am also setting the priority to the highest when making the push request.

Hi - I unfortunately had to use Hubstaff tracking software to complete a job. It required me to give it Firefox permissions. I do not recall everything. I do remember that it required Document privelages. It seems a rather intrusive software. I have tried looking through settings to disable permissions and could not find it specifically. Any assistance would be greatly appreciated.

It makes me very sad that you have incorporated this "feature" into Firefox. It makes me livid that I must manually opt out of it. I can no longer recommend Firefox to others.
