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?

While playing one of those free poker games there seems to be excessive RAM memory usage. Nothing else running which can account for it. Also, it shows several Firefox processes while, again, there's only one tab open.

The reason I noticed is that the game which usually runs smoothly began to be choppy/jerky, so I opened Task Manager to have a look. Note: Didn't investigate internet connection speed.

Why is Firefox using so much memory and slowing things down?

I think the title covers it. Until recently, pressing the <Backspace> key on the keyboard would take me back to the previous webpage. Now it doesn't.

Using FF v87 in Win10 Home.

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.

Is there a way to set a web site as my home page and not have to reset it every week or so? Also, when will we be able to choose what web site is loaded when we open a new tab?

Either I'm a dork or the instructions that I have found are not very clear. I have been trying for several days to transfer my settings from my desktop to a new laptop. I have gone to the %appdata%\mozilla\firefox\profiles page until I'm blue in the face. I transferred a directory called "m80s2e9e.default" from the profiles directory on the desktop to the %appdata%\mozilla\firefox\profiles directory on the laptop but keep getting "Firefox profile cannot be loaded" error. What am I doing wrong? Thanks, Dale Webb

Hi,

I had to delete all my profiles and completely reinstall Firefox because Firefox was not changing the color of previous websites to purple no matter what I tried. I thought I could delete the profiles and create a brand new one to start over fresh.

After reinstalling Firefox (latest version) I have run into a problem where under <about:addons> <Plugins> it shows a yellow box and an error saying "Widevine Content Decryption Module provided by Google Inc. will be installed shortly".

This message won't go away and Widevine will not be installed at all. I cannot browse and Netflix, Hulu, HBO Max etc.

I have tried unchecking and checking the <Play DRM-controlled content> under <about:preferences> which does not work.

I have also tried going to this (link)link and manually installing it but the webpage for my OS's .zip file won't load for me.

I have recently switched from Chrome to Firefox. All features that I used in Chrome seem to exist in Firefox as well, until I found out that there are no local overrides in Firefox?

Some Information about this feature(it firstly appeared in Chrome's dev build in 2017): Local Overrides

Personally I found this feature very useful and convenient when debugging directly in your browser and immediately takes effect after a page refresh.

I wonder if anyone else submitted a feedback or even had a discussion about this feature? I tried to send a suggestion about this feature but they temporarily disabled the submission form.

Hi there,

We use GMail/ Calendar/ Drive for our business. On the official account, I am seeing a continuous - multi-day - situation where my Google Drive won't load when I point my browser to it unless I do at least one refresh after getting to Drive and waiting for my list of folders and documents to show up.

In the mean time, the following error shows upon on the bottom left of my screen - "The server encountered an error. Please try again later." - this has persisted for over 2 weeks when I restarted using Fiefox earlier this month. I do not get this error when using Chrome or Safari.

Today, I am also not able to see the user who last modified a document or a folder last, as you can see in the image below.

Please tell me what I can do to fix this issue.

Thanks, Mahesh

Hello, It has been more than 2-weeks since Firefox cannot access www.google.com issuing the error page : "Did Not Connect: Potential Security Issue", and the following advanced data :

Websites prove their identity via certificates. Firefox does not trust this site because it uses a certificate that is not valid for www.google.com. The certificate is only valid for the following names: www.google.com.eg, *.google.com.eg, google.com.eg

Error code: SSL_ERROR_BAD_CERT_DOMAIN

Hi, I'm using ASNA Wings AS400 Web app. Ctrl-V shortcut does not work.

I observe this error from the controller.

I don't have a problem in other browsers.

Hello everybody,

There are more and more websites that have functions that no longer work with Firefox and force me to use Chromium instead. Do you if there is any chance that an upcoming release will put everything right?

Thank you in advance Virginie

I have used/accessed Google Maps for years - so many I can't remember and now today I get this message

We are sorry, but you do not have access to Google Maps. Please contact your Organization Administrator for access.

Is this a FireFox muck up or what?

For a number of days now I can not log into Scotia Bank online but I can with Safari so I know the site is not down. Once I try to enter I get this msg Sorry, we couldn't complete your request Sign in to online banking or our mobile banking app to continue. With an under construction icon. I have tried deleting recent history and have restarted Firefox but no change I love Firefox and it is my goto browser but something is wrong here. I have also tried to enter using firefoc from a different computer....same issue.

Hi, guys
Get this message in pop-up window. How can I fix it?

Like many users, I find Google's 'before you continue' pop-up annoying. Because I automatically delete cookies on browser exit, it keeps popping up as it doesn't remember my settings. I have installed Google Consent Dialog Remover, and it has been working well... until now.

I just did a search for a place, and tried to click on the map to go to Google Maps. The dialog intruded, despite the add-on. But worse than that, when I clicked 'I agree', nothing happened! I cannot get to the maps page at all. I've tried disabling enhanced protection -- no change. I've tried disabling various add-ons -- no change. I've tried restarting FF in safe mode, but the same problem persists.

I can't figure out how this is happening or what to do about it. Any suggestions?

Thank you!

I just turned off AdBlock Plus in the Add-Ons screen and downloaded ublock origin to try it out. There is no icon for this new plug in to be found anywhere. I can manually go in and change the settings on this plugin in the add-ons screen but there is no icon anywhere to go in quicker or to show a report of how many items were blocked. When I try to Customize my toolbars, the icon is not available there either. The nearest threads I can find on this topic are from 2018 and their solutions are very basic use. Yes, of course I restarted the browser. TIA.
