Firefox Support Forum

Hello, I hope someone can help me.

Ever since I updated firefox, my cpu is almost at 100%. With only 2 or 3 tabs open. I updated from version 106.0.2 to 112.0.2. Before this update, I could have several tabs open, up to 10 and the computer would run fine. Now with 3 tabs open, it gets really slow. And I can hear my desktop suffering (the fans go to full speed). When checking the task manager, firefox is taking all the memory and the cpu usage is almost at 100%. I have to keep restarting firefox.

The conditions are the same. The only thing that changes was updating firefox. I already searched for ways to reduce the firefox cpu usage, but nothing changed.

Is there a way to fix this? Or how can I go back to an older version of firefox? Because I'm afraid my computer will die from simply opening 3 tabs.

Thank you in advance.

Every solution which I have found for Firefox 89 "Proton" so far which moves the Tabs Bar below the Navigation Bar (AKA "address bar"), with the Menu Bar above it, does NOT move the Tabs Bar below the Bookmarks Bar. The Bookmarks Bar appears to be overwritten and blank, and occupies space below the Menu Bar, Navigation Bar, and Tabs Bar. This empty space separates the three bars which are implemented and the content of the currently-selected tab below it.

Currently, my userChrome.css file is a copy posted by Cor-el (?):

@namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul");

Evidently, the text editor for this website does several things to the above original text that, frankly, seem unnecessary and undesirable. The .CSS file is just an unformatted text file, so what is the problem with simply copying its contents and pasting it in to the body of this post?

Which is also to say that I do NOT have a clue as to what any line in the file is meant to do, what effect it has, why it is even in the file at all, or why it is written in the way that it is. So DO NOT tell me that I "CAN" create a Cascading Style Sheet on my own when I cannot even modify one that has been provided.

On the face of it, something is missing from the above CSS text. What change needs to be made to the above content so that the Bookmark Bar will appear between the Navigation Bar and the Tabs Bar??

Thank-you very much for your time and attention to this request for assistance.

My bookmarks toolbar disappeared. I was able to restore it, but it's blank. Using an add-in, I can show my bookmarks in a side pane. That pane does show a Bookmarks Toolbar folder, which has the expected contents.

Additional issue: how do I rearrange my toolbars. The desired order, from top to bottom is title menu navigation tabs bookmarks

Windows 7 Pro, Firefox 94.0.2

Much thanks!

So I've got Proton UI forced on me today in 92.0 update and accordingly had to spend my entire evening trying to repair all of the damage. So far I've managed to fix menu spacing and the way tabs look all while not breaking previous walls of text in userChrome.css meant to fix even older UI problems. Still one thing I failed to find any solutions to is the bookmark drop-down menus color issue. Those menus used to be gray, but now they are all bright white, which to me is super annoying. Any tips on how to fully recolor those?

I'm trying to create a DOS batch file to clear the current profile's cache (web site data only, not cookies). I have it working fine using a hard-coded path of the existing profile (I only have one profile), but I'd like it to remain viable in case a newer profile is created for whatever reason. Is there a way to retrieve the path into a variable?

Thank you!

Hi,

I normally delete all history, including cookies, each time I log out of Firefox 99.0. I have two sites for which I would like to keep cookies. I entered them as exceptions, but each time I log out those exceptions are lost.

Is there any way I can those specific cookies?

Thank you.

I access a CCTV Network Video Recorder on the same private/LAN that I'm on using an PC via HTTPS. It's been working fine for nearly a year. Recently it won't access via HTTPS any more with the Error Message "Secure Connection Failed An error occurred during a connection to 192.168.1.30. Certificate key usage inadequate for attempted operation. Error code: SEC_ERROR_INADEQUATE_KEY_USAGE

   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've contacted the vendor but they seem at a bit of a loss. I can connect using HTTP, and an Android App (spit) still works too. I did find a Stack Overflow article from 2020 mentioning a possible corrupt cert9.db and/or cert_override.txt files, but as it's so old I wanted to ask for further advice before I start hacking things around. On another PC using the same browser version on the same network I get the attached response, not the same as the one I get and it will allow me to accept the risk. Can anyone help please?

Hi, for the long time when I have opened an PDF with external application, it was downloaded into system %TEMP%, then deleted after ext. app was closed. Very fine and expected.

Since ca. few weeks such PDFs are now downloaded to Desktop - and not removed afterwards! It's quite annoying to clear them again and again. I've checked, my %TEMP% and %TMP% are set correctly and writeable.

Hi,

I have 2 online stores built using Wordpress, both use the same theme, 'Storefront' and both using Woocommerce. The site with the issue, I am using a child theme.

Today I noticed the credit card input box on the checkout page is missing on the site with the child theme - the input fields aren't loading at all. (see screenshot) The issue only happens on Firefox and Firefox mobile. Everything displays on Chrome and Edge browsers.

I have deactivated all other plugins and checked after each one to see if the problem persists - it does. I have also tried using the Twenty Twnety-one theme to see if that makes a difference - it does not.

The site has previously been working and all boxes / input fields have been displaying properly until today.

If I inspect the element using FF console the document within the iframe is missing. Yet, when I use the console via Chrome or Edge it isn't (as expected becasue it displays on both browsers).

Any ideas as to why this behavour, will be appreciated - thanks.

Regards,

NOTE: I am using; Windows 7 / Android 8.0 FF 96.0.1 Chrome 97.0.4692.71 Edge 97.0.1072.62

I could have sworn a week or two ago I was able to open .tiff files in the Firefox browser. But this week, when I click on a file, it goes straight to saving them to my computer. Is there a way to change this setting? I checked in my options, but did not see .tiff.

I'm running 96.0.3 (64-bit) on Windows 7 Ultimate 64-bit. Firefox has suddenly started having trouble with my local library's website. Chrome loads it just fine. Here's a sample URL:

https://jocolibrary.bibliocommons.com/v2/record/S36C592151

Firefox tries to load that for 60 seconds or so and then says "504 Gateway Time-out The server didn't respond in time. "

When I go to the main site:

https://jocolibrary.bibliocommons.com

Firefox will load it, though it takes a while, and everything seems ok except it flashes the message "Could not retrieve availabilities via API. Baker_And_Taylor short-circuited and fallback disabled." When I try to use the Search function on the page, I get the 504 error mentioned above.

I've tried running Firefox without add-ons and the same thing happens. I've tried deleting the cookies for this site as well.

Firefox has never had trouble with this site before late last night.

Hi,

Another bad change for me after last update. When I click on the NEW Tab I don't see the icons or tiles of my most used websites anymore . Only the top search bar and a down menu with the 10 most used websites. Where did the tiles go?

The article Customize your New Tab page to hide or display content doesn't work . I cannot get into settings to change anything. Is there another solution???? I would like my tiles back.

Thank you,

Amy

Problem: Firefox scrolls up to the top of page when I click on any video link on Tiktok site.

Details:

• Problem also exists in Private Window.
• I tried disabling all Extensions and it didn't help.
• Works normal only in Safe Mode.
• Tiktok works fine with other browsers.
• Page works normal 1 time after initial loading. I click on any video and it opens. When I exit video page and land back on video index, problem starts. Any mouse click (right,left and middle) makes FF jump to top of the page (even without scrolling. It's supposed to scroll just like when you press HOME on keyb.).
• 2 different behaviors on Tiktok Main Feed vs Tiktok User's Feed. On the Main Feed, when I click on a video, I see the page jumps to top but it opens the video link after a 1/2 sec delay. On the User's Feed, video link doesn't open. It just jumps to the top and does nothing.

Version: FF 96.0.3 (64-bit) for Desktop PC OS: Win 7 SP2

Any suggestions to pin and fix this?

Trying to use the seach box in the centre of the Firefox homepage (google search engine) .. everything I type goes up to the address bar . Tried changing settings - I see there's a search box option in the 'tool bar' which looks to be up at the side of the address bar. cant understand why we need another one as well as the one in the centre.

Also by turning off suggestions and not choosing the 'search box option in the 'tool bar' , the address bar is now only accepting URLs so searching isnt working.

So ..1. Is the search box in the centre no use?

        2.  Does search work with all suggestions turned off?

Firefox began returning a PR_CONNECT_RESET_ERROR error on all websites a few days ago. Chrome likewise. MIcrosoft Edge is working fine. I am running Windows 7 with Kaspersky. I tried turning off the Windows Firewall and the Kaspersky protection, but it didn't help. I also tried disabling plugins, theme, and add-ons but it still didn't help. Any suggestions?

I have a Netgear Readynas attached storage device. I am unable to connect to this device using Firefox. I encounter : Error code: SSL_ERROR_UNSUPPORTED_VERSION

It is not an dangerous site, it is my network storage device.

Is there a way to configure Firefox to connect to this device? Thanks for any help

How does one specify which program opens a .zip file after it is downloaded?

Presently, the download functions properly, but when I click on the file, VLC media player opens; have no idea why; how can I specify 7-zip File Manager instead?

Thank you. Appreciate.
