Firefox Support Forum

My ISP is Plusnet. When I try to access their website using Firefox browser I get the following error:

=====

Secure Connection Failed

An error occurred during a connection to webmail.plus.net. Cannot communicate securely with peer: no common encryption algorithm(s).

Error code: SSL_ERROR_NO_CYPHER_OVERLAP

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
   Please contact the web site owners to inform them of this problem.

I have reported the problem to Plusnet but they say 'not our problem'. Their reason being that the problem does not occur using Google Chrome.

Can you help please?

My job requires me to download and open files in new tabs consistently. However, when I download these files, I don't want the download panel to obscure my vision. Can I disable it?

Over the past week I've had this error popup a few times when Firefox is launched:

"You've launched an older version of Firefox. Using an older version of Firefox can corrupt bookmarks and browsing history already saved to an existing Firefox profile. To protect your information, create a new profile for this installation of Firefox."

I haven't yet spotted a pattern, but the most recent time it happened, I had the browser already open and either opened a new window or clicked Firefox in my start menu. The new window showed my homepage (blank tab) but was unresponsive: I couldn't type into the address bar, click a bookmark, or even close the window. The existing window was fine, so I closed that but had to kill Firefox in Task Manager.

When I relaunched Firefox, I got the above error message. Luckily I use Sync, so my many bookmarks are backed up. But of course all cookies have been deleted, so I have to login to websites again.

Firefox is up-to-date (84.0.1, 64-bit) and running on Windows 10 Enterprise. I even uninstalled, cleared out the data in AppData\Roaming\Mozilla (plus Local and LocalLow), and reinstalled.

As I said, this has happened a few times over the last week (3 or 4?) and is starting to get annoying now!

Any ideas? Thanks!

Hello,

I just upgraded to Firefox 87 and noticed that I wasn't able to go back to the previous webpage by clicking on the backspace button like what I have done in the past if I'm not using a mouse on my laptop and had to click on the back button in the toolbar with the trackpad. I'm not too sure of why that happened with the upgrade and was a little surprised about that. Hope I can be able to get around this in some way if one of you know anything about this. Thanks.

This is the site https://one.walmart.com/content/usone/en_us/company.html this site I connect to for work related issues, I can use private browsing, but not the regular browsing.

Any clue why the add-ons like Adblocker and frankly all the others no longer show on the toolbar? Makes them useless when the icons are missing. Anyone have the answer? I've refreshed. I've re-installed. I've stood on my head - nothing seems to help!

Using Firefox and accessing my gmail account. A notice comes up saying "A pop up blocker may be preventing the application from printing the page. If you have a popup blocker, try disabling it to open the window". I have no idea how to find what this pop up blocker is so I can disable it.

Awhile back [the question was asked], however the 'solution' is not what we are after here.

Once upon a time, there was a table with the Firefox downloads. And in previous versions. That is what I am looking for. I do not care, repeat, do not care, about the form input selecting 'latest' platform, etc.

Assuming also there is a method of downloading offline installers using tools like wget.

Thank you...

I've recently updated to 92.0.1 and I've noticed that when I download a PDF attachment or file that firefox opens in a new tab rather than using the default adobe program. I've looked at settings and applications and changed to to "always ask" but I don t get any option to use adobe to open it or any other program. Also it seems to save the file in the downloads folder as a "firefox html document" and not a pdf file

Firefox updated. After updating, whenever I try and load Firefox, I receive the following error message:

"XULRunner

"Error: Platform version '91.0.2' is not compatible with "minVersion > = 91.0 "maxVersion < = 91.0"

I click, "OK" to confirm... and Firefox closes. When I try to update Firefox once more, I receive no response from teh System. When I try to load MaintanceService, I receive no response. What's teh deal here. Any answers?

It seems like something has changed recently, I don't remember having such problem before. As you can see on one of my pictures I have browser settings changed to always ask what to do with every file extension, yet encountering link to pdf file it loaded automaticly in special frame instead of showing just link to it. I included pictures of this frame, settings and another screenshot of the same website in Opera browser with similar settings where nothing loads itself.

Is there any way to block such pdf-frames in current version of Firefox?

Getting error SSL_ERROR_BAD_CERT_DOMAIN on all my sites that are signed with a SSL Cert from my internal CA since updating past version 99

This appears to be a bug starting after Firefox version 99 on Windows because after i upgraded to Firefox version 100 i started getting this on all my SSL Certs from my CA and they worked fine prior to the update. Can anyone confirm if something changed after version 100 that is causing this?

Thank you.

Immediately on update to 96.0 this afternoon, multiple sites failed to load - Google(Maps, News etc), Yahoo, Flightradar24 etc - others partially loaded - then sat there blank. Explanation of errors is NOT clear -

Is it possible to revert to previous version? Everything seems to work fine when using EDGE!

Hello, Firefox 91.0.2 shows in dev. console: Firefox can’t establish a connection to the server at ws://127.0.0.1

The Private browsing window has the issue too, but i am unsure if it really disable all extensions.

When i use different Firefox profile, then the localhost site i am trying to load is loaded without that error. So how to discover please which FIrefox profile setting is preventing the loading please?

How do you remove The Firefox Title bar from my desktop? It prevents me from clicking the "Accept or Decline" buttons for example on software installs for example. on your support page I tried the "firefox menu> + customize & disable the title bar through the button in the bottom left corner of the window". There is no "customize" option.

Hi

I don't know what's happened to cause this, but for the last few days if I grab a torrent file online, I only get the option to save the file, no option to automatically open in my torrent client.

I have been to Firefox general settings, and Applications - "Choose how Firefox handles the files you download from the web or the applications you use while browsing" but .torrent is not listed. When I search "torrent" in the Applications search box, I get only "magnet" as a result, nothing for "torrent" files (see image).

Any advice on how to automatically open .torrent files from the web in my torrent client would be appreciated.

Good afternoon folks I can't watch Netflix on my Firefox browser. Do you know why is there a plug-in what is missing or something? He says the version is not up to date While my Firefox is always up to date, can you help me further. Thanks in advance from Trimmy.

Hi, new updates on Version 98.0.1 quite a hassle for me. It auto-download all my files even when I just want to view. Is there any other way to disable this feature? I opened Setting>Download but there is no disable button or checkbox for that. Please help me. Thank you in advance.
