Firefox Community Forum

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.

I opened Firefox on one of my computers as usual today but the whole performance changed. Used to go to my home tab and select various news sites to see what was happening. First, when I scroll down the bookmarks, I would hit the "news" and click on it so all the sub items would stay in the scroll, but instead of that, it wanted to open every item as a new tab. When I finally started opening the various news outlets, it opened them in new tabs, it had always opened in the same tab. Then, I couldn't close the various tabs it had opened. I would go to the tab and hit the "X" but it didn't close the tab. I had to use a drop down menu to close a tab. And when in a site, I used the scroll button on the mouse, instead of scrolling, it made the page larger or smaller instead of going up or down. What could make such a change in behavior? I opened up the 'settings' on it and looked at 'tabs' and they were the same as the ones that are on this computer that works as expected. Both computers have it set to open all previous windows and tabs. Both have the same settings for 'tabs' and 'browsing'. I don't get it. Both are version 143.0.3 (64-bit) I have Ubuntu OS.

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.

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?

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 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.

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?

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.

I installed Firefox on my new computer. It imported setting from Chrome. That's not what I wanted at all. Now, I can't get rid of that information that was imported because it synced. How do I get rid of this data permanently? I have Firefox on my old computer but I don't want to connect online for fear it will sync and contaminate my other Firefox installations. How do I clean out my online profile?

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.

I just had to sign in to this forum although I had never logged out. I am using Firefox 143.0.3 (64-bit) on Linux Mint 22.2. It is not the first time I am having to login again in one-by-one the sites I visit. And before anything else, I have not changed any of my privacy settings and no new profile has been created due corruption of my default one. It is not the first time this happens lately. Any chance with the Firefox update? I think I installed one quite recently.

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

Hi Firefox Team,

I know how hard you guys work and I've used you almost exclusively since the beginning in 2003 and talked a lot of folks into switching to you over the years.

I'm so frustrated about your decisions to change the options for what we users want on our home page and new tabs. Seems I can only use a blank page or your default home page. And if I want my normal home page I need to click on the home icon. In the course of a day, that's a LOT of extra clicking or the alternative, typing my search query into a tiny URL bar.

Are you planning to change this? Or is this Mozilla control by default the new norm? I'm so sad to admit to be exploring Mullvad and Brave now. Never would have even considered it, even though I'm consciously weaning off other US digital products.

Thanks for any suggestions and for all you do. (Yes my IOS is up to date)
