Hi – I have been with Thunderbird for a while now but didn’t use your email program as I have been using Gmail for several years and still do. When I finished with my previous ISP, I copied the folders holding all my old emails to the hard disk on my PC. Is there any way I can use Thunderbird to read/delete these emails using my hard drive as the source and without using an ISP?

Very soon after startup it begins to stutter with the spinning beachball of unresponsiveness. At first it will spin, then come back for a few seconds, then spin again. Eventually the whole app is unresponsive.

The troubleshooting steps I see on here all start with "Go to [some location in the menu]". I can't do anything with anything in Thunderbird. I can force it to quit and start it up again, that's about it.

It is also always asking me for the passwords of some of my IMAP accounts. These are big accounts, some folders have several hundred thousand emails. The Inboxes are smaller, maybe a couple hundred in total at the moment. The last configuration I was able to make put it into Unified mode.

The damn thing is that after having been useless like this ever since I installed it, last week it started to work fine. Stayed that way for several days. Eventually that failed, though, and my whole Mac ended up locked up the way the app is, I had to manually power it off.

I don't know if it writes any info about what it's doing to a log file somewhere, I am not having much luck trying to find any information here. Just other people with similar problems but no substantive replies.

Using Thunderbird on an older Mac laptop, running macOS Monterey 12.7.5.

After a forced shut down, my home page is suddenly blank. All my tabs are missing. All my most used links are missing. All the reading suggestions and pocket is missing.

Is there anyway to restore these items?

This has been bugging me for ages. Happened on Windows 10 and now on Windows 11.

I start watching some video on YouTube or whatever, decide it's not useful/what I want, stop playing it, close the tab or navigate away, but if my device locks, the controls for this old, discarded video, that I didn't want to watch, are on the lock screen.

I wouldn't mind if it was a video I was currently watching but it's somehow remembering the last thing I started to watch. I can see no hint anywhere else that it's still active in any way at all.

The only way to get rid seems to be to close Firfox.

This is very annoying because it seems you can't watch anything without Firefox remembering it and putting on the lock screen until the end of the session, so it could be cluttering things up all day unless I close everything and (in my case, because of prvicy settings) delete cookies and log myself out of most sites.

I've tried multiple searches but all I've found here is a post about turning off media.hardwaremediakeys.enabled but I don't actually want to do that, I just want Firefox to forget videos when I've closed the tab or navigated away from them.

Elsewhere I found a suggestion to disable dom.media.mediasession.enabled but that setting isn't found.

Any help much appreciated.

I have two questions:

1. Will WASM and JIT be turned on or not affect the operation of RLBox?

I currently have the following about:config settings set to false, I'm wondering if this will cause the RLBox to not function?

javascript.options.ion javascript.options.baselinejit javascript.options.native_regexp javascript.options.asmjs javascript.options.wasm

I hope Mozilla staff will consider listing the operating status of RLBox in about:support, so that it will be clear at a glance.

2. Enabling "security.sandbox.content.shadow-stack.enabled" will cause add-ons to not function properly.

This setting seems to have been around for a long time. Is there any progress on this? Chrome has supported this feature for quite some time.

I would be grateful if you could help clarify this and inform me of the answer.

After one of the updates a few months ago, I have started to have trouble with firefox. After a while if I try to open a new tab and type in a link, the tab will try to load forever and I will not be able to open any more as doing another tab and typing a new link will have the same problem. I found that at first I could close the browser and reopen it to have the tab fully load and refresh whatever was already open, but after a bit that started to have an issue too. Most times now if I shut down and relaunch firefox within a few minutes the browser will open with all of the tabs open but they are all blank, with no links filled in, pages loaded, or anything. If I close and reopen after that then it only opens with a "new tab" page and everything that was open is lost. None of the more recent updates for firefox have seemed to fix this issue.

Thank you.

Unlike opening a regular new window or even just opening a new private browsing tab in an existing window, when I open a private browsing window, the address bar isn't auto-selected. I know I can use 'Ctrl+L' to select it but that's not a habit I've been able to train yet, and doing so would be much more frustrating than just using firefox in a more intuitive way. How can I change this? Is there anything that can be done? I can't find any relevant setting when digging into the 'about:config' section, nor in any of the regular app settings.

Hello. I have window10. I have primary password which must entered before accessing any site. or the last 3days my computer asks me repeatedly to enter my primary password. and the circle goes on.

So I am unable to use my computer.

I was searching for a support phone number to explain myself better. Sadly I could not find any number. Please help. Thank

Hi. I just hoped on my computer and firefox seems to not want to load any site. Somehow this support page is the only thing that seems to be working. My other browsers such as Chrome is working perfectly fine, I'm able to search whatever & watch videos no problem so it does not appear to be a wifi issue...

Everything I search on firefox leads to a blank page that doesn't appear to be loading no matter how long I leave it for. The menu button in firefox does not work either

I've tried: - Restarting the computer several times - Turning off Anti-Virus - Clearing cookies & data

I've attached screenshots of what it looks like whenever I try to search for something... Looking to hear of any solutions you may have!

On a laptop running Windows 11, all videos I play in Firefox have been strangely dark and orange. Depending on their original appearance, this can make them unwatchable.

This only affects videos in Firefox, and only on this laptop. Chrome, Windows video player (and Firefox on my other devices) do not share this issue. The issue affects all monitors I connect the laptop to.

I have attempted: -A thorough search of Firefox settings and found nothing related. -Refresh and reinstall of Firefox -in about:config

   gfx.color_management.native_srgb to true
   Confirmed ui.videoDynamicRange was set to to 0

None of these has helped. According to all the evidence I can find online, a similar issue was caused by a problem with HDR video files and fixed in an update 2 years ago, but I am running version 127.0 and am up to date.

Windows 10. Have used Firefox for years with no problem. Out of the blue, when Firefox is invoked, it comes up, but the screen dims after a few seconds, an the hourglass appears and Firefox freezes at that point. I have to use Task Manager to close it. I tried uninstall and that failed. Then I manually deleted the Firexfox program files. When I tried to install the program from Firefox, that failed as well with a window that pops and says there was a problem. Then the install window freezes (!) and again I have to resort to Task Manager to stop the program. What to do to get Firefox running again? Thanks. Bob Ochsman ochsman@gmail.com

This site:

https://www.treasurydirect.gov/log-in/

When you click "Next" button it opens in a new tab the following URL:

https://www.treasurydirect.gov/RS/UN-Display.do

Produces a "page not found" error. Works perfectly on Chromium, Chrome & Vivaldi.

Hi! After a routine update today to Mozilla Firefox 127.0 for Linux Mint, Firefox is asking for my master password before letting me continue. Sync does not appear to be enabled.

I'd really rather it didn't do this, because my password manager is now always open and accessible. Previously, the master password request was only triggered when I came on a site that needed a password.

Anything I can do to fix this?

Thanks for any pointers!

My Problem: When I open any Dropdown for my Favorites (including the Bookmarks arrow on the left) it leaks past the Firefox Window and behind my Windows toolbar (When Using DisplayFusion only, more on that later). Some items then become unreachable: https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2024-06-15-08-17-53-5a6e2c.png

This does not happen with the settings dropdown. It correctly stops at the toolbar: https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2024-06-15-07-57-17-2e5d8a.png

What would fix the problem:

• The behaviour of the Favorites dropdowns should be the same as the Settings one in my opinion.
• I would be fine with dropdowns staying inside the Firefox Window at all time.

Note on the cause of the problem: Using the default Windows ToolBar makes the dropdown go OVER the ToolBar: https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2024-06-15-08-17-14-bc7e78.png

However, I am using a software called DisplayFusion that overrides Windows ToolBar for extra features and customization. The dropdown goes behind DisplayFusion's toolbars. I will also ask the devs on their side for a solution but I still think the dropdowns behaviours between Settings and Bookmarks on Firefox should be the same.

Thanks!

On startup TB pops an error box up saying ' There is no email program associated to perform this action'. When dismissed TB continues to open normally. No other errors seen during operation.

I have checked my Win 10 Control Panel Apps options. TB is the email default. MailTo, file type .eml and all other settings I can see are set to TB as well.
