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.

I was able to stream news from CTV news site but for some unknown reason I cannot stream it like I used too I cannot figure out why! Something must be wrong with my setup. Please help me fix my problem.

My problem is the following. The website of my favorite football club regularly embeds videos within their pages. Clicking of the video within the club webpage shows the video without leaving the webpage. Recently opening the club site with mozilla stopped enabling me to see the embedded videos. An example of what I see on my screen now when using mozilla is in the first image uploaded below - instead of showing the embedded video, all I see is a small red rectangle with a "play" button in it. If I press the play button, the video starts, but shows within the extremely small rectangle and I cannot watch it.

This is not so when I use Edge or Chrome, as shown on the second image uploaded below, showing the exact same webpage (the address is https://levski.bg/video/%f0%9f%94%b5-%d0%bb%d0%b5%d0%b2%d1%81%d0%ba%d0%b8-31-%d0%b1%d0%b5%d1%80%d0%be%d0%b5-%d0%b3%d0%be%d0%bb%d0%be%d0%b2%d0%b5-%d0%b5%d0%bc%d0%be%d1%86%d0%b8%d0%b8-%d1%80%d0%b5%d0%bf%d0%be/ ). The embedded video is clearly seen in its full size within the page, and when I click the play button it starts showing the video normally within the webpage without leaving the site and sending me to youtube, for example.

My question is, what is wrong and what can I do to start seeing the embedded videos normally again?

Thank you, Georgy Ganev

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.

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

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?

I asked the following question and was sent to this answer, which does not apply to current versions of Firefox: https://support.mozilla.org/en-US/questions/1228045 My question: how do save a username on Firefox for a website without saving a password because I do not want to save the password?

I am unable to get Verizon to verify my account when I am using Mozilla Firefox. I can get Verizon to verify my account if I use Google Chrome or Microsoft Edge, but I would rather use Firefox. Can you help?

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.

I have no idea how 100k people can review an extension labeled ICLOUD PW EXTENSION and you guys can't either remove it for the scam it is or show it has your approval as an extension up to FireFox security standards. 2.7 stars 100k reviews looks like a scam. Simply my feedback. Can't tell if I should trust so I'll never trust it until it's sufficient enough.

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)

I restarted my computer and Firefox has deleted my profile, including all bookmarks, settings, history, and add-ons. I had to make a new account using this email and google account which is the same email and google account I had on my old profile. Is there any way to retrieve my old profile?
