The latest update of Mozilla Firefox to version 119 x64bit for Windows 10 seems to have peculiar problem. With this update my browser is not allowing to print a page or webpage with print option as "Save to PDF". The print preview of the page is shown with all settings but on clicking print button there has been no file got save or rather no file PDF or anything else gets create. In the same computer both Microsoft Edge and Brave Browser are allowing saving of any rendered page in their browser to save as PDF. This issue is recognized by me after my latest update of Mozilla Firefox. However, the same version of Mozilla Firefox x32bit running in my Windows 7 32 bit machine working correctly. I have tried all the options recommended over internet in this regard by Mozilla forum and others but nothing had worked for me. Even adding of any third party add-ons also remain defunct in this latest Mozilla Firefox browser. This is a serious bug and should be corrected as early as possible and therefore putting this herewith seeking a functional solution.

When I followed instructions, it sent the login file to the flash drive I designated but in an Excel format & I don't know how to print it in a readable (.doc format). Any help is greatly appreciated. bucretired@yahoo.com

Hi, Since latest update, loading a video damn slow, few minuted or maybe more to load a video, when I copy the link and open in edge, it very fast, thus, this is mozilla problem, not youtube. Please check the screenshot as per attached. Thank you.

I removed the Firefox Relay, however whenever I want to open my email its still there and I have to keep entering my email address manually, How do \i get rid of it?

This only happens when clicking a link from an email in Thunderbird most of the time it is a news platform. I have to copy the link and open a new tab in Firefox to have it work.

I am using QUIC enabled load-balancer where the load-balancer insert Alt-Svc header in the first HTTP/1.1 response but mozilla is not switching to HTTP/3 for subsequent requests, instead it continues with HTTP/1.1 however randomly it works which means mozilla is using HTTP/3 I couldnt understand this intermittent behavior on mozilla. Looks every time if I close and reopen the browser, browser is using HTTP/3 as expected. If I refresh the page multiple times then I do see switch to HTTP/1.1.

-Load-balancer configuration, there are two virtual-host

1. HTTPS with TCP listening on port 443
2. QUIC with UDP listening on port 443

As per my understanding when access website, for an example "example.com" firefox sends its first HTTP/1.1 request and in the response load-balancer is inserting Atl-Svc "h3=:443", ma=86400 however for subsequent requests firefox is not switching to HTTP/3

• From uploaded images you can see the different, working scenario and non working scenario(both cases load-balancer insert Alt-Svc).
• I am using firefox 121.0a1
• All HTTP/3 and QUIC related configuration are enabled in firefox
• Using self-signed certificate
• Domain Name is not registered. (added in /etc/hosts to point the IP of Load-balancer virtual-host)

Your code writers need to write code to handle Facebook. When scrolling through FB the feed constantly jumps ahead 5 or more posts... It's not a FB issue, its a Mozilla issue, in as much it doesn't occur with Google Chrome, or Microsoft Edge... I could use them for FB but then I won't have my Firefox addon's..... Maybe collaborate with their code writers and ask how they addressed this issue...

All downloads "fail" using Firefox. I have tried many things. Some on the internet says the fix is difficult. Other browsers have no issues with downloads. I go to them when I need to download something. I like Firefox, but if I can't resolve this issue, I may have to go to another browser. Help.

Hello. I am finding on different devices i have that firefox won't let me do things i could do before. Example. On my cellphone. I can't login to twitch.tv nor can i get into my yahoo mail account. It says i have an unsupported browser and i didn't have that problem before. The twitch problem is the same on my pc. I can't login. The login and my credentials are there but the button won't let me log in. Please help me. Thanks. Susan

Have sold loads on Ebay using only Firefox as the browser. Tried to list another item a few days ago, and after entering the details on the first page (Item description and section to list it in) couldn't get beyond that page. The next page appeared not blank but as light grey filled rectangles where the text etc should be. Obviously tried reload. Same over the next day or so. In desperation, used Edge. No problems with that, using the same first page which Ebay had stored for me. Just tried again with Firefox - same fault.

Title. I've followed every guide I've found but the issue still persists. I've created a new profile, reinstalled ff after deleting the whole file from my pc, deleted all cookies for a dozen times, disabled all extensions, started ff in that problem mode or whatever it's called and I still can't login to certain websites.

I type my login credentials, press "continue" and nothing happens.

I hate how much information Google gathers from their users but I used Chrome for five or more years and I never had this issue with their browser. Not once. Even now I constantly have to go back using Chrome because with it I have no issues logging in to the sites while on FF I just can't.

What is going on?

The title pretty much says it. On some phpBB forum I am member of, since yesterday, I can't write long messages and see what I'm writing.

When my texte is bigger than the default frame, the scrollbar jumps at the top of the post while i'm still writing. This doesn't happen with other browers on same webpage.

Possibility : the deepl addon i just installed  ?

Any idea ?

(sorry if i'm not clear enough, english is not my first language)

I've tried deleting all history, cache settings. Deleting and reinstalling Firefox. Backing up existing profiles and restarting. NOTHING except starting in Troubleshoot (Safe) mode makes a difference:

I use Yahoo mail from my Firefox browser (mail.yahoo.com). Today Firefox won't let me begin a new email. I click the "compose" button, which should open a new blank email, but nothing happens. I tried in Safari and I can do it there. Please advise and thanks for your help.

In the Microsoft Store there are all these updates for video extensions like "AV1 Video Extension". Should I be doing these updates? Do they make any difference to streaming video on the Firefox Browser?

I need to pass a pc scan on my new hp all in one desktop for a new job with Arise.com It allows me to use mozilla firefoc for my pc scan, I continue to fail. please help
