Now this method does not work trying to get print preview back. Firefox is my web browser. I am in windows 8.1. Seems like Firefox did some updates again and now I can not get print preview back! WHY DOES NOT FIREFOX LEAVE WILL ENOUGH ALONE WHEN THEY HAVE SOMETHING GOOD? Bring back the old classic print preview button back and leave it. Now how can I get the old print preview button back???? Need help!! Thanks philm

I can't send emails out of Thunderbird but can receive them, not sure what to do? Is there a phone number I can call with Thunderbird for help? I'm not that savvy with all this.

I'm trying to perform the clean reinstall for Firefox on my computer. But, I see the instructions for the uninstall, Delete the Firefox installation folder, which is located in one of these locations, by default:

   Windows: (Note: Check both folders.)
       C:\Program Files\Mozilla Firefox
       C:\Program Files (x86)\Mozilla Firefox 

Being I'm not computer wizard I had trouble finding the location of such folder. But when I accessed my program list in my windows program list I see a program named Mozilla maintenance service. When I click on that I see a format/window to "uninstall C:\Program Files (x86)\Mozilla Maintenance Service\." Is this the program/folder I need to uninstall to complete the proper instructions I need to perform a clean install? If so, when I delete it I then reinstall Firefox once again after the uninstall procedure? Is performing the uninstall procedure going to screw up my Firefox browser and my many bookmarks I have accumulated over the years? Can someone please help and explain? Thank you.

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.

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.

OSX Ventura 13.1, 102.9.0 (64-bit), Gmail imap, when Tbird applies filter to move message a strikethrough copy remains in inbox. A non strikethrough copy is in allmail. When I try to delete the ST copy in inbox it just removes the ST and the message remains. The left click menu delete works. None of these actions have any effect on the moved message. Messages are moved to Local Folders. When I select an unread message in the inbox it immediately changes to ST status. No messages have ST in Allmail. I tried to set the delete action to move messages to a "New trash" folder and most of the inbox vanished. The "Inbox" appears to be worthless and undependable. All I am trying to do is to have my filters work like they used to when I was using POP3. My wife's windoze machine is now having similar issues.

I have sent several emails and get no reply, how am I suposed to fix check or see my saved passwords if they all look like this...3b4a3f36-7056-4eee-bcb3-2b0838fa07e1

We've been using thunderbird for more than 20 years now at work. It has proven itself reliable and production ready. I am sorry to say in the last 5 years or so every update has been worse than the previous one becoming the least reliable piece of software ever. Constant crashing ie 8-10 times a day, lack of smtp communication with the servers, and other constant issues basically make this unusable.

PLEASE forget about aesthetics and concentrate on reliability.

Ok, this might be REAAAAALLY weird that i'm talking about a firefox version that was released in 2012. But i really need it on this windows 2000 VM. The problem is firefox 9 - 12 is not loading any websites or webpages. It crashes instantly upon opening them. Versions lower then firefox 9 - 12 work flawlessly. Probably nobody will answer this but it is really important for my VM.

Posting on behalf of a user who hit the VPN inbound queue with a question better suited for this forum:

The tab bar, toolbar, and address bar placement in my Firefox Desktop browser has recently changed. I have been trying to revert these recent changes as they interrupt my current workflows.

I DO know which prior profile save contains the desired info however, it contains many files and I DO NOT KNOW which files I need for the bars to be restored. If you could provide me the name(s) of the file(s) that holds the bars data, I am probably saved, hopefully saved.

Firefox - Android I don't seem to have an option to move a bookmark into a new bookmark folder.There is supposed to be an option in the menu (after you click and hold the selected bookmark) but the menu only has 3 options - 'open in new tab  :. open in private tab. :. Delete. '. -. Am I missing something ? Can anyone help

For the past two weeks, I've noticed that embedded maps make my browser immediately crash. I initially thought it was a Firefox problem, but I have been having a similar issue with Safari. This does NOT happen on my iPhone using the same two browsers. This also does not seem to effect Google Maps or embedded Google Maps, but embedded maps from other services. Anyway, I'm posting here because Firefox conveniently provides crash data, I'm not sure what else the cause could be and I'm hoping someone can help.

Two websites this has been consistently happening with are The Empire State Trail bike path (https://empiretrail.ny.gov/) and a NYC vaccine finder website (https://vaccinefinder.nyc.gov/). Firefox immediately crashes, though with the EST website it seems to be tied to the pathway of the trail being drawn (crashing after I've zoomed in a few times and the path has to regenerate). Safari doesn't totally crash, but forces a site reload and after it fails a second time says it can't display the site.

Any ideas what the issue could be? I'm on the latest version of Catalina (10.15.7), Firefox and Safari and seem to have all security updates for all.

Here's a link to the latest crash data: https://crash-stats.mozilla.org/report/index/1389c870-51cf-4790-b0a0-fd01f0211202

Thunderbird’s connection to one of my gmail accounts failed today.

I removed the account and then tried to add it again to Thunderbird.

When logging in using a Google generated App password, I receive the following message:

"400. That’s an error. The server cannot process the request because it is malformed. It should not be retried. That’s all we know."

OAuth2 is in place, and I’ve carried out all other recommended checks I can find on your website. My other Gmail accounts are working fine.

Please can you help? Many thanks.

Recently I upgraded my Windows 10 to Windows 11 and since doing so, I've had consistent errors while browsing the web on Firefox. Most notably the "Humm. We're having trouble finding that site." error message.

For example, when visiting, say Verizon.com, the tab will display the aforementioned error to which I press Try Again and the website loads correctly every-time. No hiccups on the refresh.

I've tried the following:

1. I've performed a completely clean uninstall of Firefox and then reinstall
2. Cleared all browser history/cache
3. Removed all extensions
4. Disabled IPv6, HTTPS Over DNS, No Proxy
5. Ran through Firefox's troubleshooting
6. Used Firefox Troubleshooting Mode in the Browser
7. Tested that the problem does not happen while using Edge

I've never had a single problem on Windows 10 with Firefox. Curious if others are experiencing the same issues and if there are any fixes. Nothing else on the PC has changed.

• Windows 11 21H2 2200.348
• Network driver is the latest Win11 edition
• Firefox 95

Hi

I have a thunderbird with 3 google accounts and 2 ovh accounts Since today I'm annoyed with my google (no problem with ovh) accounts that ask me for my password every time I try to search new messages.

I confirm the password, I confirm on my phone that "it's me", I confirm that I validated, it seems to work but

- it does not retrieve my new emails
- it asks me again for the password the next time

I am in POP port 995 and SSL/TLS / OAuth2 I tried to delete the saved passwords, to disable the firewall I'm out of ideas...

Thanks in advance for your help

For the last 1-2 weeks FF has started saving web photo files as .AVIF files instead of whatever extension the photo actually is online. I cannot find anything in the settings to change this. I am not sure if this was caused by an update, or something I did.

I am using Win 10 64, FF is version 95.0.2 (64-bit)

Anyone have any ideas on how to fix this? Thanks.

I'm on the latest version of Firefox, and it's unable to play videos on Amazon.com & Netflix.com. Neither did the one before 96.0. I first saw this on Netflix.com and when the tech started asking questions about my operating system, I knew they had pulled a fast one. Now Amazon.com has done the same thing with Firefox. This browser should be hiding the underlying operating system, because it's not necessary. I can use both websites with Chrome and have no issue. The same version of Firefox is on my laptop, but it has no problems because that thing is on Windows 10.

I won't bother with all the nonsense written about troubleshooting, because this is strictly the functionality of those websites peeking under the browser to check the O.S. Firefox needs to fix this hole immediately! You're messing with my money now. Monopolies shouldn't be able to control our hardware like this; they're not paying for any of it.

Oh, my TV is having a problem with the apps, so I was forced to watch videos with my computer instead. My laptop screen is too small and can't have my booming speakers connected to it. My desktop monitor is 34".

I'm using freshly-downloaded Firefox version 102.2 on a brand new laptop (Windows 11 Pro version 21H2), and every single extension is showing a "Installation aborted because the add-on appears to be corrupt" message when I try to install. I have tried checking for updates, quitting and reopening firefox, restarting my computer, refreshing firefox, uninstalling and reinstalling firefox, as well as any and all combinations of those. I've scoured these message boards and nothing is working for me. Please help!

I am going around in circles here. I have searched and all the options I have found appear to be out of date or don't work. All I want to do is increase the size of the fonts I see in the left hand folders list and the folders message lists in the main panel. It's far too small for me and everything I have tried makes no difference. Please guide me.
