Firefox Support Forum

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!

Since I updated to Firefox v.91.0 I get this error:

Secure Connection Failed

• An error occurred during a connection to support.mozilla.org. PR_CONNECT_RESET_ERROR

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

when ever I try to connect to websites via Firefox only. I've tried many things like reinstalling Firefox and I know its an issue between Firefox and my Antivirus (Kaspersky,) but this didn't happen before Firefox updated to v.19.0 though. I've tried https://support.mozilla.org/en-US/kb/firefox-cant-load-websites-other-browsers-can and many other things but nothing works to fix it. I've switched certificate stores and other 'fixes' I've read on this website and others to no avail. It does this with or without any extensions in Firefox.

This only started when I updated Firefox to version 91.0. It doesn't give an errors/issues on any other browser I've tried so far (MS Edge and Chrome) so must be something with the version 91.0 update?

Any ideas to fix this would be great. Thanks!

WidevineCdm plug-in crashes everytime when I try to play disney plus or amazon prime. I fit the requirements via the disney plus site. Can anyone assist? I was streaming fine last week and now its not working.

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?

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!

A website MultiSafepay.com has saved my CVV number in Firefox.

How do I edit the autofill data?

I can't get to the same payment page, to be in a position to delete it.

Most links on this matter refer to:

 Options => Privacy & Security => Forms and Autofill

However in my Version: Firefox 98.0.1 (64 bit) running on an up to date Windows 10 this feature is missing or deprecated.

Can anyone say how I could edit/delete this specific entry, or point me in the direction of where this data is stored?

In the mean time I can't recommend using Firefox for entering critical security data, where websites can allow the storage of CVV numbers.

Hello. After reading numerous posts addressing similar issues & having no success, I've decided to post a question of my own. I am running the current version of firefox, 94.0.2. I use the Search Bar religiously for searches to sites like google, wikipedia, youtube, amazon, and ebay. I NEVER use the address bar for searches. I have attempted to disable all functionality associated with searching via the address bar. When I go to the address bar, it is because I have a specifc url I know I want to type with a specific destination in mind. Occasionally, I have a need to just go to the home page of one of my search sites, most often it's amazon.com. Recently (not sure which version of firefox) I've found when I go to the Address Bar & type amazon.com, I cannot just go to amazon.com, instead the address bar turns into a search bar. How do I disable this? Its driving me mad! I swear I've disabled every option I can within about:config related to urlb. Please Help. I don't want to switch to Chrome, but I'm tired of my settings getting messed up every time mozilla pushes a new version.

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).

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

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?

Ok so it's been a long time that i left chrome and joined the firefox community but there was always something which felt left out, so i downloaded chrome again and found what that was. It was the size of toolbar.. In chrome toolbar is smaller but in firefox it takes some space. So i want smaller toolbar here in firefox because i love every other thing here. So is there any way to do this? Thanks,.

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?

Following a Windows 10 update, I tried to open Firefox and the following popup message appeared. "the code execution cannot proceed because VCRUNTIME140_1.dll was not found. Reinstalling the program may fix this problem." I have tried several times to download the latest version of Firefox, but during it's installation the same error message appears. How can I fix this problem and get Firefox to work normally.

How do you completely turn off update notifications in Firefox 89? on win 7 pro?

in address bar: type the following:

About:config

press enter [or go to]

choose:

show all

search preference name

app.update.silent

boolean                                  click the + and set it to true

 restart firefox browser and the nag was gone for me.

I saw this posted a few times, BUT they left out important details

after typing in app.update.silent [you must add it by pressing the + sign] yes boolean as the other apps. are set to boolean on my win 7 pro machine. yes I am in America and English is the only language I know. :( [sad isnt it?]

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

I have lost all sound comming from firefox after disconnecting an audio output device while it was being used.

To be more precise, the output device is shared between two computer via a hardware usb switch. I was a bit to fast switching from one to the other multiple times and all audio bugged for a few second, everything worked after that except for firefox.

I have no sound comming from firefox even when using an some other output (such as a headset from a jack).

Firefox does appear in the volume mixer but no sound to be seen there either. (see attached image where firefox and spotify both are playing music, but only spotify is working as intended). However firefox does not appear at all in eartrumpet's volume mixer

I have tried : - PC reboots - firefox re-install (un-installed, deleted the %appdata%/firefore, before re-installing) - turning FF hardware acceleration on/off - using a different profile (about:profiles) - disabling all plugins - disabling / enabling every audio output in the device manager
