Firefox Support Forum

Firefox works great on every other video site. But Youtube will not show or play video. I have refreshed Firefox, disabled add on. Restarted my computer, tested all hardware. No Bueno...

Hi,

I have Windows OS and use Firefox as my main browser. Firefox settings are set for dark mode and it works in google.com etc, but when I open iCloud Notes, it's full white and not in dark mode. Can someone advise how to change iCloud Notes also to dark mode? I have cleared cache etc, not helping.

Almost every time that I open a new session of Firefox I get a message that there is a problem and it needs a refresh, which removes the extension I use all the time. Any ideas why this keeps happening over and over and what I might to resolve the problem?

When I pause a video (any site) and go to another tab / stay on the site, after a seemingly random amount of time the video starts playing again.

I'm using latest Firefox on Ubuntu 22.04 (snap).

I've tried (didn't work):

• Disabling media hardware controls through about:config
• Disabling autoplay through about:config

Sometimes all add-ons / extensions break randomly and are disabled (the icon of the extensions is also broken under "Manage Your Extensions").

The extensions are visible under "about:addons", but the slider is turned off and the icon in front of each extension is broken / empty.

It seems that deleting these 2 files- compatibility.ini and extensions.json inside the firefox profile folder, usually fixes the issue. Only these 2 files though, don't delete anything else.

No need to mess around with the ff profiles or anything else, just deleting those 2 files and restarting the firefox usually fixes the issue with the "unregistered" addons.

This thread is for the search function, as I found some VERY old and outdated suggestions for the aforementioned issue using the search function.

I wonder what causes the extensions to "unregister" randomly.

I have 3 computers (2 desktops, 1 laptop). I want to permanently delete approx 300 unused/unneeded passwords. I deleted them from computer #1, then logged out of Firefox. The new count was 346 passwords.

I went to the second computer, deleted approx the same number from computer #2. The new count was 324 passwords I returned to computer # 1 and logged back into Firefox.

Within a short time, computer #1 is at 759 passwords, and computer 2 is at 691 passwords.

How do I get the deletions to be permanent? It's the second pass at doing this and I'm FRUSTRATED.

Ever since the latest update, the picture-in-picture function stopped working properly. If I activate it, the video will automatically go to full screen, and I need to press the full screen button multiple times to move it down to a small box. I am using Firefox on a Mac laptop.

Is it possible to import bookmarks for a different Mozilla account. Apparently I have 2 different Mozilla accounts. I had been using (I'll call it account #1) for quite a while, and recently subscribed to Mozilla VPN service. When I subscribed i gave it login info for "Account #2". How can I keep the logon info for the VPN, and get my bookmarks imported from the old (routinely used account #1) ? Or, can I change the VPN service to the old account (account #1)? I know how to add another device to the VPN account, but the "accounts" are on the same "device".

Thanks...

Some webpages, that I must log in to, are coming up blank, when I attempt to login. No error, just blank white page. Two examples are paypal and textfree. I have cleared everything I can think of or find on the internet. I have refreshed and restarted several times. This has all started int he last few weeks. The two sites mentioned are ones I really need access to. I am not sure if it is my machine or the browser.

Hello Good People,

I installed Firefox a few days ago and it was looking good. I don't like that icon in the top-left hand so I right clicked it and removed it. All was good. However, today there is a blank black space in the corner as if the icon was back (but without an actual icon). It's only a small thing but it bugs me. I want the tabs to be shifted all the way over to the left like they have been up to today. It's triggering my OCD. Anyway, any advice appreciated.

Best Wishes

Matt Hammond

Anyone experiencing issue with YouTube on Firefox - I am not able to select suggestions on YouTube search using up/down arrow keys - On Ubuntu 22.04 - Firefox 124.0.2

After signing into an account with Schwab.com, the site has a "Launch" button that opens the Schwab "Streetsmart Edge" trading platform. However, after signing into Schwab.com with the Firefox browser, clicking on the "Streetsmart Edge" Launch button does not work. "Streetsmart Edge" does not open.

This problem only occurs when using Firefox. If using Microsoft's browser there is no problem.

Previously, until about two month ago, the Firefox browser never caused this problem. It worked fine for many years.

I prefer the Firefox browser versus Microsoft. Please research and repair this issue.

I already found many users asking the same, but they didn't get a reply.... at least I didn't see any.

I want to protect my password memory with a master password - fine. But in 99% of my time, I don't need to enter login data. Even worse, if FF starts on an "invisible" monitor, I cannot move the window.

Is there a way to have FF prompt only for the password if I attempt to log into a site ? ... it already does that when I cancel the start-up prompt.... so is there an "auto cancel at startup ?"

I realized since I upgraded my MacMini to 14.4.1 I can no longer 'post' into any of the yard sale/garage sale sites I am on, not even MarketPlace. All I get after a long wait is a 'technical problem' notice. Am I doing something wrong?

When using picture in picture on Prime Video, my subtitles aren't showing up in the window, but instead on the original page, despite prime video being one of the original supported websites. Any ideas on how to fix?
