on and off issue for a few months now. i dont know if its a firefox issue, a youtube issue, or something else about my laptop. everything says i have the latest update, maybe part of an update broke youtube, i dont know for sure but at this point i have to assume its firefox because it works fine in another browser and mobile app, but i highly prefer to use firefox

sometimes a video will play normally until i "interact" with it: if i have to pause, it wont unpause if i fast forward or rewind, audio will do so but the video will not. or vice versa if i click a different video, whether the current one is done or not, the new one might load 70-75% but not complete and just stay on the current video after any of these happen, the page is basically unresponsive; i can open a new tab but youtube will not open in that tab, but anything else works completely fine. if i close the tab or browser, there is a delay before it actually closes and sometimes the audio is still playing after the browser closes, in which case i can only restart my laptop entirely.

ive tried to reprt this to youtube but i dont trust it actually got to human support. i also tried the "report a broken site" in firefox the other day.

Please see attached image of the problem.

I have tried looking on Google for ideas but have not found anything on this or how to fix. Hope someone can please help would be amazing!

Google -

400. That's an error

The server cannot process the request because it is malformed. It should be retied. That's all we know.

It was working fine on the new computer until yesterday. Now I get a pop-up box that says: ' Unable to connect The connection was refused when attempting to contact localhost.

The site could be temporarily unavailable or too busy. Try again in a few moments.

If you are unable to load any pages, check your computer's network connection. If your computer or network is protected by a firewall or proxy, make sure Thunderbird is permitted to access the web.

On my Samsung A05 Thunderbird does not show received email dates only the day. This is useless for finding emails going back more than a week or two. I don't care what day of the week it was received, just the date and time. Earlier solution offered (via message lists) not in any of my menus so cannot use. Please advise how to show dates. Current OS Android 15 A055FXXSHDZF1/ A055FOJMHDZF1 / A055FXXSHDZF1 with security patch level: 5 June 2026 Also cannot find support/about option in the settings menu to show the Thunderbird version.

Hi,

I assumed that bookmarks and passwords were tied to my account and that by logging in; I would sync them in automatically. I just reset my Windows 11 and had all files deleted.

I used to do this with Google Chrome, but now that I'm a Firefox user, resetting my PC and logging into Firefox after a fresh download, I have nothing? I cannot find anywhere to sync this back, do I have any hope or did I miss the opportunity?

Hello, In FF 152.0.5 (aarch64) on macOS 26.5.2, I am noticing that every website that has a checkbox in a form does not work the way it should. The only indication that the box is checked is a slight "highlight" around the edge of the box, nothing actually in the box. See attached screenshot from the USPS website.

Also, the NO checkbox wasn't even visible until I clicked the area next to it. It was just blank.

I've seen this for set-up pages for WordPress plugins and on standard contact forms (using CF7 plugin) where the checkboxes so very little or no interaction to the user at all.

Grant it, I know now what to look for and how to use these. But any standard user is going to be absolutely confused by this unintended (I Hope) browser behavior.

I cannot access my Yahoo email account currently on desktop computer, using Windows 7 Pro and Firefox 115.37.0esr. The Select Verification Method window appears but the cursor changes from an active hand to just the regular cursor shape and nothing will be active in the window. This isnt a problem on my phone or when using Chrome on the same desktop. Is there any chance of resolving this with these versions of Windows and Firefox?

I have an issue when trying to forward an email that contains an attachment. I receive the following error message:

"Sending of the message failed. There was an error attaching the file. Please check that you have access to the file."

I am using Thunderbird version 152 on Windows 10 Pro.

This issue only occurs when forwarding emails with attachments. Other email functions appear to work normally. Has anyone else encountered this issue? I would appreciate any help or suggestions. Thank you in advance.

Yesterday I downloaded 90 emails from my mail server. Only 5 of them were filtered correctly.

Upon reviewing the remaining 85 emails, I observed that many of them "should" have been filtered. So I opened up the Tools - Message Filters and applied the filtering to the INBOX file.

Almost immediately, all 85 emails disappeared. They were not in the Trash folder, nor were they visible in any other folder or mail box that I could see.

It was recommended to apply the "repair" to the INBOX which I tried; However, all that happened was 318 older emails that I have processed a few days before reappeared in the INBOX. Which interestingly would not sort by the date indicated for the email; they would only sort by subject and sender.

It was further recommended to close TB, and delete the INBOX.msf file. Which I did do. In addition, I also restored the INBOX to the previous days file using my daily backup files. That file shows 101,076 kb of info contained in it.

I reopened TB to find once again nothing in the INBOX, and when I tried to re-run the get msgs aspect, the result was the system telling me there were no email messages to collect.

Yet I know the same 90 emails are still sitting in the mail server system.

Why did this happen?

Where did the 85 emails in the INBOX go to?

Why isn't the set of 2200++ email filters not automatically filtering all emails once they are collected, and distributing them to the appropriate email file folder / mail box?

What recommendations are available to help me resolve this situation and prevent it from happening again?

Also, I have a txt and html file of the 8 Jul 2026 filter report. Why can't I upload said files along with this set of information? Why are attachments only restricted to image files?

Thank

Hello everyone .

I have used Firefox for years now and I always keep my sync on. When I sign in to a new device, I sync and all my data. I had a problem with my PC today and I downloaded Firefox for mobile on my Android tab. I tried signing in but forgotten my password, I did a reset and logged in and tried to sync but I can't find my previous data. I can't even see any of my previous devices. This is strange because it has always worked

Any help will be deeply appreciated.

I am trying Thunderbird with the intention of replacing MS Outlook. So, I'm using it alongside Outlook. This is happening with my Yahoo.com account. FYI - Xfinity migrated my comcast.com account to mail.yahoo.com, which has caused a lot of problems, as well.

Hello. I have been trying to use the Firefox built-in VPN. I click on the VPN icon, click "get started" and it asks if I would like to continue with my Mozilla account. I click "Continue" and it says I am signed in and to click the VPN icon again to turn on the VPN. When I click the VPN again, it does not give me the option to turn it on. It only shows the "Get Started" button again and starts the process over. (see attached image)
