The audio on videos from YouTube/Facebook/Twitter/any website which allows video/audio play, is cracking. Mostly happens when there are multiple tabs open. What can I do? Also, I have tried doing a full uninstall and installing again, continues with the same problem. This did not used to happen before.

FF will now not let me log into a site Ive used many times, Ive cleared the cache, remove data, Im not to much techno knowledge but have done that then gone to saved log ins and removed original log in that was saved, gon back to the (site which is my energy supplier) put in my email, then password all is correct but it just will not open anything the dots on top left of page just keep going back and forth, yet if i go onto IE and log in it comes up instantly, maybe I should change!!

I need to continue to use an application (Web Site) built with Flash Player for the first 3 months of 2021. Flash Player support ends on December 31st 2020. What is the plan at Mozilla in terms of restricting access to Flash Player in 2021? - For example, is there a timebomb in the browser so that Flash Player will seize to work on December 31st? - If not, would Flash Player become inaccessible following the first browser update in 2021? If yes, do we know when date is scheduled for approximately? - Will the behavior be the same for all Firefox versions (Light, Enterprise, iOS, Android, etc..). Thank you!

Update 89.0 changed the browser theme to something I don't like, too pale and pastel. Options to change back to what I had aren't available. The options presented are now uglier than this sick looking theme.

How do I undo 89.0 update? Pretty much looks like (from release notes on another post) 89.0 has nothing at all to do with security and it's just someone at Firefox wanting to change things just for the sake of changing things.

I hope Firefox isn't going to start doing silly things like moving the first floor to the second floor and the second floor to the first floor just because some administrator feels like it.

I wish to stop the new pop-up update notification message built into Firefox 69.0.#.

A pop-up message is not necessary, irritating and tiresome.

Why is there no option available to turn it off?

Due to a System Crash at the end of October, I had to reinstall TBird 68.3 on Windows 10 (64 Bits). Since Nothing could be fixed, I upgraded TBird to V.84.0b3(64 Bits), hoping it would work better...

All my email Folders and their content reloaded themselves without any problem. However, my Contacts Folder remains empty and I have also been unable to find the correct Filters to receive any emails that have been sent to me since this Crash!

I am now desperate for help, so please don't hesitate to email me to "carl.bongaerts254@gmail.com" and please send a CC to my TBird email "info@tissim.com", just in case I find a solution in the near future!!! Thank you very, very much! Carl

How do I disable the ANNOYING message box I get every time I want to send a message to the trash folder. Thunderbird keeps asking me if I want the message deleted to save disk space. This just started in the past week. I want my deleted messages to go to the trash folder and I will manage that folder. I can't seem to find anything in settings that lets me disable this option.

When I selected the TB icon a window came up saying I must set up my existing email account. I fill in my name, my eddress and password. The next window that comes up shows TB found mobile.charter.net but my email was set up using email.twc.com. The port numbers are the same but the server names are different. When I complete this activity the end result is that my information if rejected. I attempted to configure it by hand but it too was rejected. I am using an HP desktop with the latest Win 10 OS. I don't know what to do.

Today I migrated from an older mac to a brand new one (Mojave 10.14). When I opened Thunderbird (60.8, latest update checked), the display (fonts, icons, mails... everything) had become so small it was almost impossible to read.

Zoom in/out didn't change a thing. The tiny size remained tiny.

Zooming in only worked on the add-on/plug-in page but not on the mails or on the display itself.

The "zoom" add-on won't work on mac. It was disabled many years ago.

Hi: I've just by mistake downloaded the Thunderbird Update from Ver 68 to 78 and I want to go back to the Version 68 - could you provide me with the details how to do it, please? Your earlier advice would be greatly appreciated ...! Many thanks. Tony H.

FFox 92 update today. Menu spacing went to double. No shock there. Found the CSS code below for UserChrome.css and set it up.

EX.

menupopup > menuitem, menupopup > menu {
  padding-block: 4px !important;
}
:root {
  --arrowpanel-menuitem-padding: 4px 8px !important;
}

EX:

menupopup > menuitem, menupopup > menu {
  padding-block: 0px !important;
}
:root {
  --arrowpanel-menuitem-padding: 0px 0px !important;
}

But, it doesn't get any smaller than the above 4/8px set up. Bug? Perhaps there's another CSS setting to be tweaked for V 92? I do not have any other CSS for these items elsewhere in my UserChrome file.

I can't back-up my mailbox.

• I have the same problem as in the question from markosv63 8/19/20, 10:01 PM (now archived) in that I have many emails in many folders.
• The procedure recommended to markosv63 doesn't work. That procedure is in https://support.mozilla.org/en-US/kb/imap-synchronization#w_configuring-synchronization-and-disk-space-usage.
• I don't think I use an imap account because my server type is POP Mail - Port 110 (default).
• I followed exactly the recommended procedure but the result was a folder marked updates, containing a folder marked 8216C80C92C4E828.
• 8216C80C92C4E828 contains a folder marked updates plus two files, one file called update-config.json and the other called updates. This updates folder contains an empty folder marked 0 plus two files, marked backup-update and last-update.
• None of these files or folders contains any emails.

I am somewhat disappointed. I have read several old and new topics on this subject and do not understand what is happening. Why are you complicating where it should be simple. And why doesn't it work anyway? Firefox, are you kidding?

For example this topic https://support.mozilla.org/bm/questions/1253515 Quote: " Three things:

(1) Create one or more "Allow" exceptions in Manage Permissions

(2) Check the box for "Delete cookies and site data when Firefox is closed"

(3) UNCHECK the box for Cookies under "Clear history when Firefox closes" > "Settings" (this feature will blow away all cookies whether you made an exception or not)

"

Exceptions are not working even with all checkboxes uncheked. See my settings screenshots.

firefox 72.0.2 (64-bit) reinstalled

Restore previous session - on

Delete cookies and site data when Firefox is closed - on

Exceptions added for http and https both.

There is no other sub domains in manage data

I was asked to refresh my Firefox, because it started slowly. Frankly, I'm very hesitant to do so. Last time I did that, which was some time ago, I had many problems and it took some time to repair those problems that it created. What does Firefox help suggest I do? Is there still going to be problems once I do a refresh of my computer browser? Thank you.

Today I updated my Firefox Developer Edition to version 89.0b2 and now I just can not look at this browser anymore, "Inspired new tab design" is taking too much space and now became largest and at the same time least information-dense panel in my entire desktop! I searched around the web for a bit in hopes that I will find a theme or an add-on that will revert this particular change but no luck. I really want to revert to old UI look (at least tabs bar), there should be default theme or option to get back to old style. After some investigation I found userChrome.css but don't really want to install it (maybe this is actually the way of doing this kind of styling). Please help me revert UI design to old one.

Hello dear Nerds

With the last update the Bookmarks have a wide distance when listed. Too wide! I have to scroll down endlessly to find things. Before they were neatly narrow and you could see twice as much. Kindly repair this next time please. Or can I do this? Best Ursula Zürich

If I try to drag and drop a new bookmark onto the bookmark icon (the star with the line under it), it USED to open up Bookmarks and I could place the new bookmark where ever. That no longer works.

I CAN drag/drop into a folder on the menu bar but not into bookmarks directly.
