Something has happened to Firefox resently. I can't open AARPUNITED HEALTH or E*TRADE. I' been accessing those sites for years but now I can't

 If I go into Firefox Settings, Security,  and delete resent data they will work once.

After years of using Firefox to access art sites, suddenly the sites no longer display all the images, leaving instead a verbal description of the art! This has happened in the last week! I am so frustrated with Firefox, I am considering switching to Safari or Chrome, as the don't have any problem downloading jpegs.

This small but negatively impactful change is wrecking my workflow. Can anyone help with a userChrome.css fix to restore the old functionality?

Team Mozilla: *please* fix this likely unintended change in the next update.

Hello Mozilla Support, I am getting Error 526 when I try to open YouTube in Firefox. Other websites work normally, but YouTube does not open. I have already checked my internet connection and restarted Firefox, but the problem still exists. Please help me fix this issue.

After clearing my cache, I got logged out of all of my accounts, and I can no longer sign into Google. When I enter my username it gives me a message that says “Couldn’t sign you in: this browser may not be secure. Try using a different browser.” I was able to log in using Chrome so it’s definitely not a device issue. I already tried clearing my cookies and cache again, and disabling all of my browser extensions, but I’m still getting the same message. Any help is appreciated!

Editing to add, I'm using Windows 11 and Firefox version 153.0

It used to be really easy. I have Firefox set to open lots of tabs when starting. If I then decide I don't want some of those tabs any more I simply closed those tabs and then went to settings and there was a button to save my Homepage. Then I closed Firefox and next time I started it all my tabs, less those not required, would open. Now that doesn't seem to be possible.

How do I just get rid of the not required tabs? And, in the future, if I want to add more tabs how do I get them to open next time I start Firefox?

When navigating to the site https://www.bbc.co.uk/iplayer with Firefox's built-in VPN turned on and the Location set to the United Kingdom the site still displays the message "Sorry, BBC iPlayer isn’t available in your region.". Why is this, and how can it be fixed?

When I use ChatGPT in the Firefox sidebar, I can open a conversation normally. However, when I hide the sidebar and then show it again, ChatGPT leaves the conversation I had open and returns to the main page.

The conversation is not deleted from my history, but I have to find and reopen it every time I hide the sidebar.

Is there a setting that allows the sidebar to keep the same ChatGPT conversation open after hiding and reopening it? Is this normal behavior, or could it be a Firefox bug?

I am using the latest version of Firefox on Windows 11.

Recently, suddenly, the audio files on my website no longer produce sound in Firefox browser. They work fine on other browsers and all phones I tested. Can that be fixed by Mozilla, or myself? Website is JesusChrist.com

Hi, I'm pretty sure the email I am signed in with now is what was tied to all of my bookmarks in Firefox but I had to do an account recovery and I did not have my key. When I was able to sign back in and hit the sync button nothing updated.

I am really, really hoping I did not lose everything here... is there anyway I can recover my bookmarks/passwords?
