I have 2 PCs both Windows 11 pro my desktop and my laptop both goign through the same router to the outside world both running the latest version of Firefox

With my desktop I have no issues accessing any website. On my laptop however, I can access the majority of websites but there are 2 websites (so far, one of them being www.mouser.co.uk) where I get a Secure Connection Failure - but no specific error message as such but I do get this..

The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.

If I clear cookies and cache I can then access the website once, before I get the same connection failure.

If my desktop can access the website, why can't my laptop? Any suggestions as to how can I establish what the root cause is?

Many thanks

I am having trouble sending tabs from my phone to my PC. My device is connected to my computer, and I can send tabs from my PC to my phone successfully, but not the other way around. I have no idea what could even be the issue, and I have only seen people asking about sending tabs from PC to Mobile, not the other way around. Is there something I am missing? None of the Firefox troubleshoot pages have helped.

Hi

When I visit the webpages of the Swiss Federal Post Service

    https://www.post.ch/de/kundencenter/onlinedienste

then the scroll bar will not be displayed even though the page is longer than what can be displayed on my screen. As soon as I return to another URL the scroll bar is visible again when needed.

Does anybody know what I can have a scroll bar also for this webpage?

Cheers, Pepe

When I visit an http site and specify a non-standard port, it automatically changes to https, which is not a site redirect but something Firefox changes. This site already has an https service, and the http service will redirect to https. I reproduced the same situation in chrome. Accessing the http service with a non-standard interface was normal. After accessing the https service once, the service with the non-standard port was also changed to https. Clearing the data will restore it. Is this cached? My HTTPS-Only Mode is turned off, and set an exception for this site. thx.

Hello, long time Firefox user here!

Open site https://www.desmos.com/calculator, a well-known site for math graphing In a completely empty graph (no sources of CPU usage), select settings (top right wrench button) and select the polar grid option (circular grid). Simply click and wiggle the coordinate space a bit and CPU will quickly reach 100% usage.

Tech stats: Firefox x64 (newest version), high CPU usage occurred with and without active extensions, my CPU is a i7 8-core 4GHz

This does *not* happen if a different browser is used (e.g. I tested with Chromium), or Desmos is used with the regular cartesian grid option. Ram usage and GPU usage are negligible either way.

Related: https://bugzilla.mozilla.org/show_bug.cgi?id=1446863 they claim "low fps" but I'm guessing that's a symptom of high CPU usage.

Thank You in advance! Daniel

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)

So my browser crashed and all my tabs are gone and the restore previous session is grayed out and I can't do that. Is there something I can do? I'm super upset ;((

Greetings, for some reason lately over the last couple weeks I have noticed that when I open a link to a site that I've had in my bookmarks for years it now opens that link or that page and then within a couple seconds another tab will open for advertisement or possibly even the duplication of the originally called upon link in the previous tab. I would like to stop these additional tabs from opening automatically without my request.

thanks in advance,

Hi, I noticed about a week ago that when I would have Firefox windows open on more than 3 of my displays, the newest window, when maximized, would appear with white bars. This does not occur when Windowed or when troubleshoot mode is on. I have attached a photo of the error (suggestions omitted for my own privacy). Bugged window does not respond in this state and cursor does not blink etc. Other Firefox windows work fine. I'm running a custom color scheme, Dark Reader for Firefox, and AdBlock for Firefox. Issue does not occur with Chrome or Edge, which have the same, if not more extensions loaded. Glitch presented itself near the beginning of November.

Please help!

I'll check on this every once in a while, and am willing to run tests.

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?

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.

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

Firefox browser problem. When dragging the mouse over text on a webpage to select text I want to copy, some of the selected text and an area of webpage adjacent to the text I'm trying to select is blocked by a box that automatically appears. Sometimes it whites-out a box-shape but usually it's blacks-out. This blocks that part of the page and some of the text I'm trying to select while I'm dragging my mouse and I can't see the mouse while I'm trying to select text within that box. What did I do to cause this and can I change something to make it stop? This is only when using Firefox and I didn't have this issue until October 2023.

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.

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...

Hi Firefox Team, I am a university student, and I keep getting these messages below, especially when I am doing research for my assignments; it is painful as time is of the essence. I need your help asap. I have already cleared my cache, and cookies Thank you The connection was reset

The connection to the server was reset while the page was loading.

   The site could be temporarily unavailable or too busy. Try again in a few moments.
   If you are unable to load any pages, check your computer’s network connection.
   If a firewall or proxy protects your computer or network, make sure that Firefox is permitted to access the web.

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 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?
