Reguarly with some month between I can´t send email. After many days, which is impossible to use, it is ok without doing anything.

Haven´t manage to send in many days and now it is huge problem.

When I click on send buttom on the email come text about the fail which is 100% wrong.

It say: An error occurred while sending mail. The mail server responded: (then come my email adress): Sender adress rejected: not owned by (the part of my adress in front of @) Please check the message recipient (my email adress) and try again.

This text is 100% wrong because all things is as always! Never changed it. And seeing it in setting it like it should be!

I am almost given up, this come always with months between and that is hopeless.

Please help!

New addons on Firefox become blank on restarting the browser.

They return when I manually disable and enable them once.

How to fix this? Doesn't happen to older addons.

I can not access my bookmarks links, the bookmarks are there, but the links to the internet is dead. I still have access to my home page, though the bookmarks links are dead. How can I fix this? Thank you for you help in this matter. Gary

Hi, i just got a new laptop (Asus Zephryus G16, 2560 x 1600 screen) and after installing Firefox there is a thin white border to the left of the screen when running in fit screen. This problem is not present when in a windowed mode or in F11 full screen.

I tried updating the Intel Arc drivers but this did not fix the problem. Changing to compatibility mode also did not fix te problem.

PS: in the uploaded screenshots it is quite dificult to see the white line(because the background is also white), but when the image is viewed in a new tab it is visible.

Thanks

It seems since the latest update to FireFox (129.0) I am no longer able to pick a search engine to use, I can click on DuckDuckGo or any other choice for a search and no search engine will come up?? Thank You for any help or suggestions.

I set the about:config settings when I got the new computer early last year. It's been working fine. Suddenly, searches are popping up again to the urlbar.

browser.newtabpage.activity-stream.improvesearch.handoffToAwesomebar is still set to false. Keyword.enabled is still set to false.

I see a couple of site references to browser.fixup.alternate.enabled, but it doesn't exist.

How do I get FF back to proper search in the search bar?

Today, Firefox stopped playing audio on Facebook videos and won't play Netflix videos at all (Netflix error code: F7701-1003). Youtube works fine and has audio, but several other video sites I've tried have video but no audio. It was all working fine yesterday and I haven't changed any settings.

These websites work fine with both audio and sound on Microsoft Edge on the same laptop, so this is a problem exclusive to Firefox. OS is Windows 11 Home 23H2, Firefox is latest version (129.0.2)

Things I've tried: 1. Refresh Firefox settings 2. Download and install fresh copy of Firefox 3. Toggle DRM content in setting on/off - no difference no matter what is selected 4. Ensure that 'remember history' is selected 5. Check for Windows updates 6. Uninstall audio driver, restart and fresh install of audio driver 7. Ensure it's not in private mode 8. Turn off all extensions 9. Check volume mixer allows sound for Firefox 10. Clear the cache and cookies

I can't find any more suggestions on the internet, so any further suggestions welcome!

Dear Firefox China Team, After reinstalling Windows on 2025-07-22 and installing I signed in with the same Firefox Account (this one). Unfortunately: • No bookmarks, passwords, history or extensions were restored. • I believe “Sync” was enabled before the reinstall with all data types selected. • The UI only shows “Syncing…” but no data appears. Please help:

   Check whether any sync data exists for this UID.
   • If yes, explain why it is not downloading and provide recovery steps.
   • If no, supply official evidence (e.g., server-side log) showing zero data.
   If my data (bookmarks, logins.json/key4.db, form history, add-ons) is on your servers, kindly export it to me in an encrypted archive or provide a temporary secure download link.
   Advise how to prevent this “appears-to-be-synced but actually not” scenario in the future (mandatory manual backup, verification methods, etc.).

Troubleshooting already done: – Confirmed same account, same email. – Reset services.sync.* prefs to default. – Manually triggered sync; about:sync-log shows no error codes. – Created a fresh profile; still empty. Please reply at your earliest convenience so I can continue using Firefox with confidence. I am ready to provide Sync ID or any logs you need. Best regards,

I don’t understand what Firefox is doing. For example, I used to start typing the first few letters of “weather.com”, which I visit pretty much daily, and it would auto fill “weather.com”. Now it auto fills every time with http://www.weatherbase.com/. I don’t know where that came from. Similarly, I used to type the first few letters of “duckduckgo.com” and it would bring up “duckduckgo.com”. Now it brings up a magnifying glass below the url with “Search with duckduckgo”. I am thinking it might be best if I can start over, i.e. clear out any information it’s saved about where it thinks I want to go, and start remembering the sites I am entering now.

I have Mozilla Thunderbird email application with Windows 11. Recently I have problems opening some email texts, but not all. I do receive the mails and heading, but the contents are not displayed. This goes for some mails, and I do not see any connection as to which ones open and which ones don't. I would appreciate your advise. Bo Dahlberg

Up until recently Bing Maps in the UK has the option to display Ordnance Suvey Maps and the function to measure distance.

Now, using Firefox, Bing Maps display a Beta version with very limited functionality. Using Microsoft Edge, Bing Maps have all the functionality that I expect.

Has something changed within Firefox that has caused this problem? Is there something that can be done to allow Bing Maps to work correctly from within Firefox?

I often categorize my mail in differents files and subfolders. This morning I was checking my mail when I discovered that the subfolder "Agile Retraite' under the file called "Retraite" had diseapeared completely from thunderbird. Could you tell me how to get it back ?

The camera won't turn on in the Firefox browser for Google Meet or Zoom. It says it can't find the camera or that it's turned off. I have checked my Windows 11 settings and desktop apps have access to the camera. I have also checked the settings for each of the sites and use of the camera and microphone are allowed. Autoplay is enabled too. The camera works fine in other apps and in other browsers.

I am attempting to report that Yahoo Finance is broken. From this URL, I use the "report broken site" feature:

https://finance.yahoo.com/quote/DEO/

When I fill out the information and hit "send", nothing happens. The "report broken site" screen remains active. Hitting Send multiple times has no effect.

I've tried using this feature for other pages, and it appears to work; but it won't work for this site.

Can anyone suggest why that might be? Is it a byproduct of the site's being broken?

Thanks.

I have a local folder which has 90 folders within it. These are folders brought over from Eudora (the mail system I used before Thunderbird). It would help me if I could easily move all 90 from their current "Eudora" folder to the big "main" folder that Thunderbird has. To make it clear what I'm asking, here's an example, using two folders, Danbury and Fritz.

D (folders whose names begin with D) Eudora folder, which has two folders - Danbury and Fritz F (folders whose names begin with F)

Is there any way to move the 2 folders that are currently within the "Eudora" folder so that they're "first level" folders. In other words, Danbury would be among the "D" folders and Fritz would be among the "F" folders.

The only way I know to achieve this is by manually creating the new folders, moving the items from the old folder to the new folder, and then deleting the old folder. This is cumbersome.

I have just upgraded to version 145 and the title bar has disappeared Even though I have the Title Bar option checked in the customize firefox panel. If I uncheck the title bar option and then check the title bar option, the title bar will appear, but when I close firefox and then restart firefox the title bar is gone.

Purchased new laptop. Used export tool in Thunderbird to external HD. Traded in old laptop. Installed Thunderbird & attempted to import my email profile. Import tool requires zip file, but the only file on my external HD is a .default file. I'm getting new email but none of my old emails. Consulted Best Buy Geek & he determined the import tool didn't work properly because the export was missing required files. We further determined the export backup must not have worked properly.

I have one file folder that I moved certain files to that once read, they are not visible or listed in the folder. The folder massage count is 296. When I move an email into the folder and it is not read, I can see the message. Once read, it disappears. I can filter by attachments and contacts and see some but not all of the messages.
