Firefox Support Forum

After updating to the latest Firefox, my USAA Banking website will not load properly. It will only display the top banner and even that is dysfunctional. I am also having issues with Ebay and facebook. I have turned off enhanced tracking for the site. I have enabled cookies Running Big Sur 11.2.2 Bluhell Firewall 2.8

Whenever I visit Tesco website for online shopping the pages get progressively slower to the point where I get a message in a yellow banner which reads words to the effect of: 'A web page is slowing down your computer. What do you want to do?' It then gives the option of clicking on a tab to either 'stop this' or something else which I no longer recall. This message doesn't stay there long and on the times where I have managed to click on the tab 'stop this' it has no effect whatsoever. I looked up this problem by typing something about it into a google search space and came across information which says that it is an apparently known problem with Firefox. I cannot account for the testament of this answer though. I don't know who wrote it. Is this true? Is there anything I, or you, can do about this problem regardless of whether or not this is true? When this happens my computer sounds like it is about to launch itself into space and there is a distinct and lengthy lag between entering information and the website responding. It can take over a minute to move from one action to the next. eg. scrolling the page up to view the next items on the page. I really would be forever grateful if you could identify the problem and come up with a solution for this. Thank you for giving this your attention. Helen Gray.

Seit den letzten Updates laufen Netflix und Amazon Prime nicht mehr auf meinem Mac in Firefox. In Safari und Chrome hingegen läuft alles ausgezeichnet und ohne Fehlermeldung. Unsere Tochter benutzt das gleiche MacBook Pro von 2015 und hat die gleichen Probleme mit Firefox aktuell.

I have Node-Red and this page was different.

Now with 86.0 it looks like this:

New layout of page after update

The group for MusicPi used to be at the left of the screen just before BedPi's group.

Yes, there is a problem with the height/size of the groups which is/was a suspect, but thinking about it a bit more: It was working until the upgrade.

When I sign into a secure account (my bank for instance) It never recognizes my laptop and I have to have a secure code emailed or texted to me. Why is that and what can I do to fix it?

I just tried today, but I don't know when it started, but all of the streaming services I have access to are not working in Firefox (on MacOS 11.2.2, Firefox 86.0). They give the following errors:

Disney+ - Something went wrong. Please try again. If the problem persists, visit the Disney+ Help Center (Error Code 83)

Prime - We're experiencing a problem playing this video. For assistance, please go to www.amazon.com/videohelp.

Netflix - Pardon the interruption. This title is not available to watch instantly. Pleast try another title. - 1044. Error Code F7121-1331

I've tried multiple videos on each service, all produce the same errors. I've rebooted my machine. I've flushed all cache and cookies. I've tried in safe mode.

Youtube and Twitch both work. Strangely enough the "Watch Trailer" on Prime works. On the same machine Chrome and Safari play all services fine.

This makes me think it's either a privacy guard setting or a DRM setting. I've also checked my media.mediasource settings and they are all default. Play DRM-controlled content is also enabled.

Anyone have any help or other things I can check?

Hello, I've encountered a problem, when loading Youtube site, video previews are not loading. Tried to remove and disable all the add-ons in my browser, including ad blocker, but nothing helped. I also cleaned the cache and browser cookies. Can you please tell me how to solve this problem?

Firefox can't scroll down or up on some web pages. You can only navigate them hitting Tab to select the elements.

This issue has been reported before, but archived without solution. See "why can't I scroll down on some websites?" (27 May 2018):

https://support.mozilla.org/en-US/questions/1219374

This page seems to have a more particular behavior, may be it could help to pinpoint the problem: It does scroll up and down until you don't close the two pop up boxes, then you can't scroll it anymore (but you can still navigate the page using Tab). If you have an ad blocker that blocks the two pop up boxes, then you can't scroll the page at all. The same behavior happens on Google Chrome.

Every time I wake up, firefox has reset like i am opening it for the first time. i have to log in every morning, which is different from other browsers. i am wondering, is this a feature, or a bug. it also resets extensions, bookmarks, and logins. this is very annoying for me.

Yes, I have set the options to open, see attached. If I go to a website and click on a PDF it will open in Adobe Reader. When I go to Outlook.live.com for my email and click on the PDF it opens them in a Firefox preview. When I print them from Firefox it takes an average of 5 minutes per page. If I download and open in Adobe it takes seconds to print the entire file.

I have an issue when viewing my site in Firefox. I have built custom dropdown menus in HTML and only in firefox does the space between items in the dropdown appear double what it does in other browsers. I have seen were others have said this is a padding issue only with Firefox but no way to "fix" it. Looking for some solutions.

Ratsit.se has a function for copying an address. When you right-click on an adress, a yellow sign apperas. Clicking that, the whole address will be copied. This function is missing, when opening the website under Firefox (works with other search engines). The function still seems to work with Firefox 70.

SEB,se. You can get your annual account statement with other search engines, but not with Firefox - here you only get the empty form (headlines show).

Can someone explain what's wrong, or even better: fix the error?

My Firefox version is 86.0 on Mac. OS Version is 11.2.2 Big Sur.

I found that basically all color rendered in Firefox is more vibrant than Safari and Chrome, maybe Firefox doesn't handles color management right and renders sRGB in full P3 color space, lead to a over saturate color for almost every element on webpage.

Hopes firefox can fix this soon, I love the efficiency and privacy features on Firefox, This is the only bit I found a little uncomfortable.

You can test your browser here: https://cameratico.com/tools/web-browser-color-management-test/ if you have a P3 support Mac or Windows.

Why am I getting this and when will Mozilla address it? To protect your security, smartdata.jpmorgan.com will not allow Firefox to display the page if another site has embedded it. To see this page, you need to open it in a new window.

I have suddenly got thick black lines round all text boxes, and the toolbar at the top. I can hardly see facebook for them. Would this be an update causing this? And how can I get rid?
