Firefox Support Forum

This is really getting annoying. Again the 4k and 8k videos on Youtube are stutturing, saw some some improvement with Firefox 87 at least on the 4k videos. For example this video in 8k does not work at all, audio works fine and it stutters totally showing a single different frame every 10 secs. https://www.youtube.com/watch?v=5LxsViMm25o&t=54s&ab_channel=AroundTheWorld4K . My pc is running Win 10 64-bit, 8gb of ram and all with all drivers\os up to date. As usual no issue with Google Chrome while reproducing the above video in 8k.

CPU Intel(R) Core(TM) i5-2400S CPU @ 2.50GHz 4 Cores GPU - AMD Radeon R7 200 Series with 2gb.

Pls fix.

Hello Mozilla community!

yesterday I installed a program which installed adware (I overlooked a little checkbox). It also changed a couple of settings in my standard browser (Firefox) like the search engine etc. It also changed the homepage. I always had the homepage pointing to my YouTube feed. I changed it back to it using the about:preferences#home method. Under "Homepage and new windows" I set the homepage to my custom URL and the home button works perfectly fine. Yet when I open a new window (with ctrl+n, not a new tab!) it also displays my home page (YouTube). It has never done that before and I cannot find anything in the settings to change that. I tried looking in about:config with browser.newtab but didn't find anything that seemed related to my problem. A couple of weeks ago I tried Firefox Nightly and I started it up and the homepage worked fine AND it didn't display it in a new window. It only did this after it synchronized the data with my Firefox account. Now my question is: How can I remove the the Homepage from a new window (and replace it with an empty page or the Firefox Home)? Thanks in advance for your suggestions!

Kindly Jay

p.s. I attached the Troubleshooting Information and I'm using Linux

Dynamic site content binance.com doesn't work after updating firefox. You have to constantly update the page. Please how to fix it?

When I login to Hulu.com, I am returned a white page that says, "403 Forbidden nginx" And the address in the URL bar is, "https://auth.hulu.com/web/null//null/welcome". However, if I change it to http://hulu.com, I am presented with my homepage. I shouldn't have to type hulu.com into the address bar. It should take me there, automatically when I click "Log In". This is happening in Firefox on both a windows 10 machine and a Linux Mint machine. why?

In the last 2 weeks I have had issues with 3 different websites. In all 3 cases I was filling in an online form. In the first 2 I filled the form in and clicked submit and was ejected. In today's case I could see that 2 lines of text were overlapped. I could find no way to click the underlying yes/no circles. I have attached a screenshot of what I get. After several attempts with suggestions from support, I tried Microsoft Edge and had no issues. Therefore, I concluded that the fault was not in the websites. I have tried changing font size with no improvement. Help!!

Hello,

I am wondering it this is possible - I have a Windows 10 laptop that needs to be upgraded to V202H and I am told that the upgrade will probably delete all of my current programs and settings - including my Firefox install and all bookmarks. To help recover from that, I wanted to know if it would be possible to set up an alternate Firefox in a not often used local account on my Windows 7 laptop and then sync the two so that after the upgrade, I can download Firefox again onto the Win 10 laptop and then sync it back so that I can get all of my bookmarks and settings for FF back onto the Win 10 laptop.

I don't want to sync it with the Firefox that I use in my regular Win 7 user account since that has a separate set of bookmarks and settings that I wouldn't want to change. I just wanted a way to "hold" all of the Win 10 Firefox stuff and "reinstall" it, and had thought that sync might be a way to do that.

If that won't work, is there a way to transfer the entire FF profile over to a new install on that laptop once it is upgraded?

Thanks for any help! Much appreciated!

Continue to Payment on United Airlines website fails.

Making a payment for a flight on United Airlines website while using Firefox returns an error message. I am running Firefox 87.0 on a MacBook Pro that is running Mac OS Big Sur 11.2.3. The problem started approximately one week ago. If this is not resolved I will have to discontinue use of Firefox after many years. Thank you, Andy

Hi,

When I attempt to open files instead of saving them I get the dialog box with the check mark for "Do this automatically for files like this from now on." But it asks me this every single time for the same file types.

Do I have any recourse?

Thank you.

I keep getting this error code when I try to access amazon.com. This is a new problem, less then 48 hours. I can access amazon with chrome and edge.

I was recently automatically upgraded to a new version of Firefox (87.0). Now when I right-click on an image "View Image Info" is no longer available. How do I get it back? I'm a webmaster, and this feature is very important to me. Thanks.

whenever i go onto a simple html website the text displays with what looks like a angle symbol every few letters making the text unreadable any help would be great thanks

Can someone please tell me why Firefox has remove Page Info on the right click?

Sense Firefox doesn't have a setting to set all cookies to "Allow for Session", I have been doing it by my self on every page I see. I right click, select Page info, go to permissions then change "Set Cookie" from default, which is "Allow" to "Allow for Session".

I read their update page before I updated, and no where on the page do they mention removing page info and for what reason.

Does anybody have an idea why?

After installing the Native MathML extension (to get MathML typeset equations on the Wikipedia, as suggested on mediawiki.org), all equations set by MathJax/MathML turned to using STIX instead of Latin Modern. I'd like them to stick to Latin Modern instead.

The only possibly related setting I've found is `font.name-list.serif.x-math` in about:config, whose value is `Latin Modern Math, STIX Two Math, […]`. I tried to manually change the font family specification of some text to see if Firefox could use Latin Modern Math to begin with, but apparently it can't (see first screenshot attached), while it loads STIX allright (second screenshot). Latin Modern is not the first locally installed typeface I haven't been able to use, but it's the first one I have really tried to (I don't remember which one the other typeface was).

My Latin Modern font comes from TeX Live 2019 installed using the TUG installer, not Fedora's package manager. `fc-list | grep -i "latin modern math"` returns `/usr/local/texlive/2019/texmf-dist/fonts/opentype/public/lm-math/latinmodern-math.otf: Latin Modern Math:style=Regular`. I'm running Firefox 87 on Fedora 33.

So Firefox updated this morning and when I went to look for the Inspector under the Web Developer Tools, it is no longer there. I use this tool all the time and came to count on it. What are my options and is it still available?

Hello everyone. Like the title says I am seeing a lot of these type cookies being left over in Ccleaner after I close Firefox. (Please see attached image.) I have had as many as over 300 of these type cookies in Ccleaner so apparently Firefox is not clearing out these types of cookies when I close my browser like it is suppose to do with cookies etc. etc. Could someone shed some light on this whether this is now normal to see these type cookies for websites that I visit and why Firefox does not remove them when I close the browser and if not what can I do to remedy this. I have read that Firefox has enhanced its tracking prevention and was wondering if this could be the result.

Respectfully

Hello! After upgrading Mozilla Firefox to version 86.0, the header and footer setup menu in the Page Setup section has disappeared. How can I change the header and footer content in the new version?

"Pocket List" has disappeared in the drop down menu under the "library" icon where it used to be not more than a few days ago. It's not under the Bookmarks icon, either. the "Pocket" icon is in the menu bar, and I can save items to Pocket, but can no longer locate the page with the articles. "View List" does appear when you click the Pocket icon, but it also saves whatever page you're on whether or not you want to save it.
