I am using Thunderbird 115.12.1 (64 bit) on Windows 10 with the email account set up as POP3 for the Gmail account

I have a subfolder under an Inbox (Gmail account) that is no longer showing up. If I search for an email address from a sender that was in the folder, I get a list of emails showing the dates and subject, but if I click on the email, the tab that opens is blank.

My PC crashed, but I can't say for sure when the folder disappeared, other than I know it was there 4 days ago. It the the only subfolder that is missing.

Any help is appreciated. Thanks

Firefox recently got so much slower than normal. Usually it will take 5-10sec to load a full page .Now it loads very slow that I don't know how much time it takes to fully load the page.please help me with this problem. Thankyou

In Firefox, after a reboot, how can I re open my previouse sessions?

Originally I had quite a lot of open browsers & tabs. Then I needed to do a reboot, and now I've lost those previouse sessions.

Usually I just open firefox, and this opens one browser, and then all of my previous browser, and tab reopen, but this time firefox crashed, and its popup said it needed to restart, but it would re-open my previous browser and tab, but it didnt.

After following the usuall firefox help giudes, it still wouldn't re open my previouse sessions. Now if I ask it to open my previouse sessions, it just opens the recent help giudes, and not anything before the crash.

So is there a backup file of myu missing sessions that I can roll back to?

The Site Notification for Firefox for Android is broken (don't know if it's just me) I have a notification for IGN website but Whenever I click on any site notification I received it always open a " about:blank " page rather than the actual website.

My phone model is ZTE Blade V50 Vita ZTE 8550 Running android 13

In Android 14 oneUI 6.0 i have an issue while i download, the progress of download doesn't show up, i have checked everything but only the Firefox notification of private search shows up, plus when it is downloading the file i have problems when browsing, like when i use the keyboard The keyboard automatically closes and doesn't allows me to type I don't know if i explain myself clear enough

A recent update has broken the ability to upload images. I am on a Pixel 7. Firefox has full rights. I tried clearing cache. It is not a particular website. This one for instance, allows the option of uploading images to attach.to my question and it doesn't work. Hoping someone has a fix so I can keep using the browser.

Despite updating to the latest Firefox version (127.0) and performing a reset, I continue to face high CPU usage issues. The battery monitor reports extensive CPU consumption for minimal use, even when only a single tab is open. This problem is not exclusive to the main Firefox app; it persists across other Firefox-based browsers as well.

Device: Xiaomi (HyperOS - Android 14) Issue: High CPU usage across multiple Firefox versions Troubleshooting Done: App reset, tried alternative Firefox-based browsers

I urge the development team to investigate this recurring issue, as it significantly affects the performance and battery life of mobile devices. Your prompt attention to this matter would be greatly appreciated by all users experiencing similar problems.

For the last several weeks (can't give an exact date, but it's been more than just a couple weeks, less than a couple months), both my husband and I have had issues loading videos in FF. We both have the latest version of FF. I went thru "Fix common audio and video issues" and did all those things, as well as trying to load the videos in troubleshooting mode. Nothing has helped (tho now that i cleared all the cache, i'm gonna have to log back into all those websites :( ). Nothing else is problematic. Our internet connection is fine. In fact, my husband has resorted to using MS browser to watch videos--they load fine in that browser. I have no other idea what to do. Searching your database for "youtube videos load slow" only resulted in a couple hits with no resolution. Hopefully this isn't the third. thanks

I am writing to request assistance with an issue I am encountering on the latest version of the Firefox browser for Android. My goal is to open specified pages in the same tab using Intent from a third-party custom application. However, I have observed that different URLs open in separate tabs, contrary to my expectations.  Current Implementation:  Here is the code snippet I am currently using: java： Intent intent = new Intent(Intent.ACTION_VIEW); intent.setData(uri); intent.putExtra(Browser.EXTRA_APPLICATION_ID, packageName); startActivity(intent); Expected Behavior:  I expect different URLs to open in the same tab without opening new tabs. This functionality is crucial for my application.  Issue Background:  I have researched similar issues and found that users have had comparable needs using Browser.EXTRA_APPLICATION_ID. Unfortunately, it appears that Firefox has not fully addressed this functionality. The EXTRA_APPLICATION_ID is a feature that modern browsers should ideally support to enhance user experience and maintain continuity within a single tab.  References:  I have referred to the following discussions and issues for additional context:  Mozilla Support Forum: https://support.mozilla.org/en-US/questions/1364869 GitHub Issue: https://github.com/mozilla-mobile/fenix/issues/23329 Request:  I kindly request that the Firefox team consider adapting this functionality officially or provide an alternative solution if it has already been addressed. Any relevant documentation or guidance on achieving this behavior would be highly appreciated.  Thank you for your time and assistance.

I had to get a new phone, and Firefox does not accept my password. I also have it on my tablet, and it's fine, and on my laptop, and the password is correct, but the new phone tells me "Try again." It was fine on my old phone.

Hi,

ist the famous and great Mozilla FireFox Developer team aware of the issue and is working on it?

I am happey to describe in more detail if required. thx

I've removed firefox and reinstalled but for some reason my IOS continuity microphone and my Loopback (Rogue amoeba) virtual devices no longer show in firefox but they show up in firefox beta. Is there a setting that masks these devices off from the production branch?

Hi,

my firefox does not load any webpage no matter what Firefox profile I am using (created a new one for tests). I have a Win10 pc with Avast and Comodo installed, the system with the mentioned software and multiple different Firefox profiles was running since several years without problems.

A month ago I had the same issue with Firefox 126, which I guess was caused by a windows update, where I had trouble getting it installed. But after this (I had to increase the system reserved partition) Firefox was running without any problmes like before ...

Now no pages kan be load and always the crash monitor pops up.

I have been having consistent issues with Youtube when played on Firefox. Opening the "Stats for Nerds", I see that I have decent connection speed. However, I get a burst of network activity, and then it stops. Therefore, i can't watch the video. Refreshing Youtube does not help at all.

Trying on other browsers, I do not have issue. While I sometimes get low network activity, most often than not, I can play Youtube videos fine.

I have done the following:

• Confirmed that I'm running the latest Firefox version (127.0.0)
• Cleared Firefox cache
• Confirmed having issue (sometimes worse as I get no network activity even on refresh) on Firefox Troubleshoot mode

I run a dual boot system with Fedora 40 with Thunderbird installed via DNF and Windows 11 Professional with Thunderbird installed from the Mozilla download site. I have had a Gmail account configured on both sides for some time. Recently I have been seeing very slow (2-3 minutes) outgoing sends from the Gmail account on the Fedora side ( thankfully they are eventually successful), but no such slowdowns from the Windows 11 side. As far as I can tell the accounts on both sides are configured the same (I always take the automatic config option when adding an account). I have also looked at the extra account settings required for OAuth2 authentication with Fedora, and believe they are all correct. I have made sends directly from the Gmail server, and they have no delay, so the problem must be related to communication between Thunderbird and the Gmail server on the Fedora side. Interestingly, I do get the following warning message when opening the Fedora Thunderbird:

Could Not Authenticate -- Imap(imap.gmail.com)

The server for account "imap (imap.gmail.com)" refused the supplied username and password. Do you want to go to the settings for another attempt at logging in, or do nothing?

Login failed, sever replied A000002 NO Invalid credentials (Failure) [AUTHENTICATIONFAILED]

This obviously is a problem, yet it doesn't seem to be fatal, as the server eventually connects, but after the delay. I have checked my account password, and I know it is correct. I would appreciate any insights into what is going on.

To the Mozilla Community:

I have a Posteo account and set it up successfully in Thunderbird. Emails and Calendar are both working without any issues.

However, Posteo contacts are not syncing. I used the TbSync / Provider for CalDAV and CardDAV without success. And using the Add CardDAV Address Book in Thunderbird is not working either.

Posteo Support confirmed my settings are correct. (Enter https://posteo.de:8843/addressbooks/johnexample/default in the URL field and replace johnexample with the local part of your email address. )

Any assistance that can be provided to troubleshoot and resolve this issue is appreciated.

Thank you.

This just started recently, and I have no clue yet how it started or how to fix it. I have tried several "fixes" listed on the internet, but no luck so far. I'm running Thunderbird V 102.5.0 (64 bit) on Windows 11. This does not happen to any other programs that I may be running, only TB and only after I delete the 2nd or 3rd email in my sbcglobal account. It doesn't happen with my gmail account that I have running in TB also. The freeze lasts a couple of minutes, and then reoccurs after I delete 2 or 3 more emails. It seems to only affect my "inbox" and not "sent" or "trash". Sorry if this has been asked and answered before, but I was unable to find it here. Would appreciate any assistance to point me in the direction of a solution. Thanks

I have been unable to receive eMails from my internet provider (Optusnet) in Australia for sometime now. I keep getting a "Time Out" message from Thunderbird. I am using the latest version of Windows 11 on my PC.

I have spoken to Optus and confirmed that I am using the correct IMAP (Port 923) and SMTP (Port 25) settings. Is it possible to fix this in the settings menu. Or is this an Optus security issue that they are currently working on.

Kind Regards,

Jay Robertson

I am finding more and more sites that I regularly go to are no longer working on firefox. One site was because HTML5 apparently does not work on firefox. But others I don't know about why are no longer working on firefox. I thought it might be streaming related but just today I could not access one of my banks on firefox, and I tried many times, but had no problem signing on using Chrome.
