Dear Firefox Team

I recently had to uninstall and reinstall Firefox. When I logged in, I thought my extensions/themes would be there, but that wasn't the case. Can you help?

Thanks.

When I type in a Google search in Firefox, a red dotted line (not the wavy red line from Firefox's spell check; spell check is disabled) appears. What exactly is this red dotted line? Can I show or hide it in settings? Can I change the setting in about:config? Please help. It's very annoying.

Hello,

Today I updated to Firefox 143.0.3. When done (most of?) my add-ons were gone, in particular all my add blockers, facebook container, etc. Also, my search engine defaulted to Google (yikes!)from Duck Duck etc. I am very specific about trying to block all ads, trackers, etc and avoiding all Google products. Other things stayed the same like cookies preferences.

Is this done by design? Is there a file somewhere that still has all my add-on info, that I can restore.

I really would give up on browsing if I am forced to see ads all the time.

Thank you! Petrus Martens

Hello,

Google Drive today stopped loading properly. I keep getting the rotating circle or "working" in the lower left corner of the browser window. I can get it to load fine in Safari and Chrome.

Docs and sheets I already had open, I seem to be able to interact with and edit normally. But navigating the main file path in Google drive, opening folders, and opening files isn't working.

I would really prefer to not switch browsers, as my entire workflow is set up on Firefox.

Suggestions?

Thanks, Sarah

When using YouTube system freezes between 5-30 mins, of start of any video. I have troubleshooted, i have checked every extension, i have run every diagnostics on hardware and software , checked and updated every driver but no results i tried checking online but didn't file any solution , the only thing i can do is to reset my system, it does not happen in any other situation. This is happening since the start of Oct'25, if anyone has any idea how to solve this kindly help.

For the past few days hot links in Thunderbird do not open in Firefox. Selecting a link in an email opens or brings to the fore a copy of Firefox with the link address and the wait icon but nothing else happens. I have to close Firefox, copy the link location, Past and Go in Firefox, and then the linked page appears. This behavior happens even in Troubleshoot Mode, so it is not any plugin or customization. I am also running Mozilla VPN. With VPN disabled, hot links in Thunderbird open in Firefox as expected. Now you know where to look.

Also, when I tried to add Troubleshooting Information below, nothing appeared. When I selected to option to be shown what to do, this page was replaced with other which deleted all this text, and now I am entering it all in again, which is severely frustrating. On a page where the user has entered possibly a volume of information, there should not be any sloppy risk of deleting that information due to page mishandling. Open help or assistance information in a separate tab, please. Think ahead about this stuff. You are supposed to be web design experts. Instead your web site spits in my face just when I am asking for help. Think. Plus, I had to get the Troubleshoot information manually so that is not being as automatic as it appears to be , either. Getting help should ideally be a button click, not jumping through hoops.

Gmail works on my phone (Android), Chrome, Opera, etc. It will no work in Firefox that I have used religiously for over 10 years. I've signed out of gmail and signed in...a dozen times. Nothing works. If I wish to read my emails, I switch to Opera

Why?

When I use on line banking and I want to look at a check, I can not get Firefox to render a check image. Also I downloaded tickets to an event and FF would not render the Q-code on the tickets. I what to know what settings to change in order to do online banking. BTW it works in Chromium Browser, but I do not use it and have little knowledge about Chromium, I just have it on my laptop for troubleshooting.

Two QNAP NAS displayed readable web pages this morning. Early afternoon I updated Firefox with a reset and the admin pages on both servers are unusable. How can I roll back Firefox or recover the earlier version?

When trying to access many popular websites with Firefox on my Fedora 43 installation, I am greeted with a security warning page with the SEC_ERROR_UNKNOWN_ISSUER error. For most of these websites I can simply accept and continue, but HSTS-only sites will not permit this.

Affected websites include but are not limited to (based on exceptions in the certificates section of Firefox settings):

• github.io (many subdomains)
• purdue.edu (many subdomains)
• iu.edu
• ebay.com
• cbsnews.com
• iwm.org.uk
• home.cern
• celestrak.org

Any help in resolving this is appreciated.

Hello, Can Firefox not use Google's safe browsing because there are some big conflict of interests. If website owners do not put google's codes in their website, Google will block their website or flag it as deceptive. This may become a large legal issue later. Only once the website user verifies with Google, will this be cleared. I run over 400 websites (all of the same codes) and the websites that I verify with Google were all blocked with a notice that the sites were deceptive. There are no difference in codes with the site that were verified and none were blocked. So I had to upload Google's codes to each website to clear the blockage. There were no phishing, no spamming, and nothing deceptive about any of the websites. The only difference was they were not verified with Google. Thus this forces website owners to put Google's codes on their website which is giving Google way too much control over the internet. I thought firefox was not controlled by any other company such as Google. If I use other browsers such as Microsoft's Edge, none of my website had any issues. Please do not use Google services as that gives too much control to Google. In addition, Google's Captcha is really another obstacle.

how do i block my location? Nothing seems to work. I want to search a site in another country but keep being directed to the site in the country I am in. I dont want to look at that site. I want the site in different country but keep being bounced to the current country site. I getting pissed

On some of my websites information is blocked. For example on my main bank site I can sign in to the site but all of my banking information is blocked so there is no account information. On my VA website I have a similar situation with information being blocked. for example I go to the messenger section and cannot see or write messages.

My passwords are apparently lost today after updating Firefox.

What went wrong? How could that happen? Why, Why Why?

Anyway to get them back? Are they hidden somewhere?

Anyone else suffering from this update too?

Any help or insights as to why would be greatly appreciated.
