An error occurred during a connection to www.facebook.com. SSL_ERROR_DC_EXPIRED What in the world? does Facebook not keep up with its own security? or is this a Firefox thing?

Hi,

Since upgrading to FF100, almost all of the 'select' boxes on my webpages have white text on a white (or very light) background, and are only visible when hovered over, see attached screenshot.

How can I rectify this please?

i recently lost my computer to destruction. i have a number of files saved by Mozilla backup on a thumbdrive. i have several backup files dating from 2014 all the way until now. after re-installing Firefox on a new computer, i tried MozBackup to restore my old Firefox from the latest file dated a coupla of months ago this year. the files have names like Firefox 16.0.2 (en-US) - 2013-01-05.pcv or .pfc. when i tryt and load it into backup it saysit isn't a valid backup file. how can i get this to work?

Access to Google sites (Gmail, Google Search, Google Calendar) with Firefox (v. 100.0, 64-bit) is very irregular. I can sometimes open the pages, but can't, e.g., edit calendar entries. Often when I click a bookmark (in the Bookmarks Bar), or enter the URL for a Google site, nothing happens. Clicking other bookmarks opens the corresponding pages. Only Google sites seem to be affected. Is FF blocking Google?

Hello,

I believe this issue started ever since I upgraded my PC to Windows 11, and has persisted through a full reinstall. I continually get intermittent SSL errors of all types when visiting any websites. Simply refreshing the page temporarily resolves the issue, but I'd estimate 20% of the time when I try to load a webpage I get the error. This does not happen on any other browser, or Firefox on any other device on my network. Interestingly I believe this even happened on the same machine inside a Linux VM in VMware, but I'm not 100% I am remembering that right. So far, I have tried various fixes including resetting certificate authorities and changing Firefox to use the Windows certificate store in about:config, but nothing has worked so far. I'm all ears for any ideas.

Thanks!

Since the latest (5 May 2022) update to Firefox (to Firefox 100.0) my Gmail account does not work properly on my desktop running W11. Gmail frequently disconnects for varying periods, then reconnects, only to disconnect again almost immediately. Gmail will not let me open another account from within the current account. This does not happen on my Android phone where Gmail works properly. Neither does it happen when I run Gmail through Edge on my desktop. Hence I presume it results from an interaction between Firefox100.0 and Gmail. My wife has exactly the same problem using her Microsoft Surface Laptop under W10 since this latest update.

Just now, I tried to use "Email Link..." under the File Menu and got a pop-up asking me to "Choose an application to open the mailto link." I have seen this before, several times, and usually fix it by going to Tools > Settings, under General > Applications, select "mailto" under Content Type, then select Gmail from the drop-down menu.

This time, however, Gmail is not presented as an option, in this pop-up. Clicking "Choose..." just opens up a Windows Explorer file-picker window.

I tried to fix this in Tools > Settings, under General > Applications. There, "mailto" just shows "Use other..." and if I click that, the "Select Helper Application" pop-up window is basically blank, with a message at the bottom saying "No applications were found for this file type."

I refreshed Firefox but it did not solve the problem.

I have tried to attached images but they will not upload.

I am running v100.0.1 (64-bit) on Windows 11

Is Firefox will support this feature ? Or at which version will support ?

File System Access API

I cannot see saved credit cards in Privacy & Security Firefox 99.01.

I moved from a mac to Windows, and sync'd everything. I have no option to see saved credit cards in Firefox Privacy & Security.

Please help?

New computer, running Windows 11, McAfee LiveSafe came with for 30 day trial. I use Firefox, have since 1997. Just added Mozilla VPN. Old computer ran Xubuntu. Windows 11 needs antivirus because it's Windows. So. How compatible are McAfee LiveSafe and Firefox with Mozilla VPN? What suggestion, if any, does Mozilla have for an antivirus program that will work well for Windows 11 but not mess with Firefox and Mozilla VPN? Thank you.

Hi,

I would like to change the light grey hover color on menus (e.g. yellow), see attachments, probably using userchrome.css.

Does anyone know the correct code to do this please?

Thanks in advance.

Hello,

I am learning to look at websites with help of the development tools and the inspector tab and I am trying to get into how the web works and how the different programming languages interact and so forth. When moving the mouse over parts of the website, the relating code is highlighted in the inspector tab. I am having an issue as follows:

The first image shows a part of the website code. The mouse cursor is on no specific position, I marked its position with a blue arrow.

In the second image the mouse is over the red "free options" button and in the inspector tab a div appears out of nowhere. It does not appear in the code unless the mouse is moved over the button and disappears as soon as the mouse leaves the button. I have never seen that before (maybe because I am a beginner) and have no clue what happens there.

Is that done with javascript? Or with php? Or with css? Or anything else? What happens there and how can the actual code change?

In the inventor tab, does the code have to do with the DOM rather then the sourcecode of the website is that right?

Please give me some light =)

regards p3ppi

I had been using Firefox browser for awhile, but because of playback performance issue, I have to using another browser just for video playing, especially for 4K video.

Compared to Edge, Firefox seems taking more resources to playback the YouTube video and more heat. When look at the Task Manager, the Video Processing is 0%, and GPU is running significantly more resources on '3D'.

I went into about:config and changed the following values in order to widen the scrollbar:

css. scrollbar-width was true changed to false idget.non-native-theme.scrollbar.size.override was 0 changed to 100 widget.non-native-theme.enabled was true changed to false

Changing these values didn't widen my scrollbar. Without getting into coding, is there another way to make the scrollbar wider? (I changed them all back to the original settings when they didn't work.)

I clicked on 'block cookies' option( never seen this before but I trust you guys so....) when I logged onto firefox this morning, since then there are various apps I cannot get on to, eg Twitter, my banking through Nationwide, very frsutrating. So I tried to set a restore point prior to thios morning but that made no dofference, getting desperate now.

My Firefox has suddenly stopped working when websites have menus you need to scroll through on the right side. Example: websites where you are drilling down through filter options, or in Ancestry where you will typically open a record in the hints screen and scroll down through the detail. The right scroll navigation causes the whole page to scroll up and down; there's no way to navigate down in the sub-display. I have run FF in safe mode, and done a scorched-earth uninstall/reinstall and the problem persists even with no plug-ins restored. This is on a machine running Windows 11. The machine crashed right before this became a problem. Sites work in Edge without issue.

More and more I'm having to go to other browsers like Chrome or Edge to open certain websites as they do not work through the Firefox browser. Why is this and how can i get them to work before i change browsers permanently?
