Firefox use a lot of CPU time ( it reaches 100% ) while watching youtube videos in 720p on Windows 10, and videos lags and stutters too much. Not using any ad blockers, non of plug-ins are on. It does work just fine on Ubuntu on the same machine Vids also were working fine on previous popular web browser known for its spyware

Using hardware acceleration is on in browser settings. Specs are: CPU: Intel(R) Core(TM) i5-3230M CPU @ 2.60GHz 4,00 GB x64 Windows 10 Home edition 22H2 GPU: NVIDIA GeForce GT 635M

Firefox version 120.0.1 (64-bit), up-to-date

I have Firefox set to ask me where to download files that I want to download. It works for normal download links, but when I'm using my credit card company site's PDF viewer to look at a statement and I click on the download icon or link in the upper-left, it simply downloads the PDF (to my chosen "Save files to" folder in Settings). Is there a current way to change this behavior? Is this something that the website's code determines, overriding my Firefox setting?

I had set up my homepage on Firefox as "currently.att.yahoo.com". All of a sudden I can't get that site. When I try I get a message indicating the site isn't available in China. Why is this happening and how do I fix it. A step by step way to cure this would be appreciated. Please reply to aulonz2021@att.net my aulonz2019@att.net address is on Yahoo and I can't get there. I use the Yahoo homepage for most of my browsing and I am really upset that I can't get there!

When printing a page to PDF, with headers & footers, the default setup shows the date in right footer. However this date format is in (for me) awkward US format . Is there a way to show the date according to system regional short date & time ?

info: OS: windows 10 pro

 date format: YYYY-MM-DD
 time format: hh:mm (24-hr)

FF: 120.0.1 (latest to date) FF about:config -> print.print_footerright = &D FF &D format: MM/D/YYYY, h:mm PM (12-hr)

Hi, I just created a bunch of folders for my long list of bookmarks. However, when I click on Bookmarks all I see is the same long, unorganized list instead of those folders. How can I rectify this?

So it looks like notifications stopped working with the lastest Firefox version 120.0.1. Specifically notifications functionality has stopped working for ForexFactory.com. The site says browser disallows notifications though the settings in the address bar indicate that they are allowed. This is also the case for other sites like MarketWatch. Wondering if there is a bug or my install is corrupted. Let me know if anyone else is experiencing this or knows anything about this. Thanks.

I can not access for days my bank account at truist.com. It shows it is loading but never does. I CAN access from any other browser want to use! Truist says it is a Firefox browser issue.

cAPTCHA is recent problem in Firefox browser ... never before was it a problem. cAPTCHA keeps asking to choose an image but keeps on never verified ... I had to get Chrome browser to finally log in to a site I wanted.

Machine is Windows 10 with a Logitech wireless keyboard. Latest Firefox browser. Not always but sometimes when using Firefox browser to log in somewhere or enter data on some web site, I'll get an incorrect entry for a key stroke. e.g. I enter a 0 and get a 1. But if I enter a 1 I get a 1. So far the error key has always been different.

I've tested things by launching a notepad or Word document and entering the character and in those all works fine. But go back to Firefox and I get the error again. What I have to do is to close and re-launch Firefox and so far this fixes things. It's an intermittent problem which forces me to keep another browser on the machine and ready. Imagine entering a password when all of a sudden you type 'X' and it gives you an 'E'. Really frustrating!

Hi,

It hard to explain what I mean so I recorded video, link is below. I want Firefox to behaves the same as Chrome. So as you can see, when I use address field for quick search then pop-up appears with search results. And I click on these search results with middle mouse button. But on Chrome it works normally and on Firefox not. I am redirected to just opened tab what is really annoying. I must go back, input the same if I want open several result. How to change this behaviour to achieve the same what I have in Chrome?

Chrome Firefox Serach Behaviour

Also it’s exactly the same when it comes to bookmarked pages in a folder on the bookmark bar. When we click folder with bookmarks we have dropdown menu with bookmarked web pages from this folder. And when I click something with middle mouse button then page opens in new tab but this dropdown menu disappears, and again I must click folder when I want open more sites. In chrome it doesn’t. How to set it the same for this?

Recently I´ve encountered problems with (mostly) accessing nba.com. I don´t get the resultbar. Today klicking on one of the menue items (Schedule) Firefix refused to load the page claiming "Not safe". As you can see I´ve accessed the page a number of times. /Leif Arvidsson

Hello! I need some help. Every since 4-6 months ago, Firefox has been extremely slow when I boot it up at first, with some page load times taking more than 10 minutes. Some fixes have seemed to work, but they never work permanently. From my testing, it is not the result of any extension and the issue persists in troubleshoot mode. What has not helped my testing is that, after enough restarts of Firefox, the problem goes away and web pages load quickly, so this has caused some false positives. Has anyone else had a similar problem they were able to fix? Should I try uninstalling Firefox and reinstalling it?

I recently sent a lot of tabs from my phone to my computer. However, when I started Firefox on my computer, since Firefox tried to load the content of all sent tabs immediately instead loading them lazily (which I think probably should be the default behavior), it took a very long time for Firefox to display even the tab that was currently selected, and I therefore decided to kill Firefox and reopen it, in the hope that all new tabs would load lazily. Instead, when I reopened Firefox, none of the new tabs where there anymore; it was as if they had never been sent. I would like to get them back, but I have no idea how to. Does anyone know if that is possible and, if so, how?

I selected "Tips and Tricks" because I always feel like everyone seems to understand the answers and I do NOT.

I have and donated to Firefox since it began. I think it is a great idea. I have severe dyslexia and ADHD.

I keep add-ons to a minimum and my home page free of everything. I use menus to find what I need. Having short-cuts all over is too distracting. When FF is not available and have to use another browser, I find it very difficult: they are loud, busy and ads are all over.

I am finding "help" more and more difficult to understand. Do the folks realize that I don't use computers all day long? That some people don't use the same definitions as people who work with computers? (I tried to find the meaning of "default" with 0 results, phrased the question many ways.)

I am hoping a beginners guide review would help, as thing have changed since Firefox was new or "Firefox for Dummies" was written!

Is is/are there basic manuals? Please help. ("Please don't respond with what help are you looking for" - that will not help the next problem).

tell me how to undo "troubleshoot mode", read the "help" article, do not understand.

tell me how to undo the "More from Mozilla" in about:preferences. I have NO idea.

I try, but I am usually confused by these help articles.

Hi everybody, since yesterday I cannot use DeepL Translate on Firefox: most of the functions are blocked. I cannot sign into the website or download the app, and most of all the translation function is not available. I have checked uBlock but it doesn't seem to be related to the problem. No problem with any other websites, it's just DeepL. I have not changed any of my privacy or cookie settings, so I don't understand why all of sudden it's no longer working. I can use it in Chrome but I would prefer to restore its functions in Firefox, which is my main browser. Thanks in advance for any suggestions. Have a good day.
