Firefox repeatedly crashes on my, multiple times a day. I'dc really like to NOT have to change my default browser to Chrome.

What happens is that Firefox freezes, and I get a white bar at the top telling me so. I get a popup box asking if I want to close Firefox or wait for it to respond. Waiting doesn't work, so I always have to close Firefox. When I reopen it, fortunately all m,y open tabs are retained, but it crashes again within minutes or seconds as soon as I click on anything.

There only thing that seems to work is a reboot of my PC. But the respite is short before Firefox crashes again.

I've disabled most plugins, but that hasn't helped. Is there a way to create an event log within Firefox that I can share with someone at Mozilla to help e debug the issue? It's got to be something local rather than Firefox itself; I can't imagine this is happening to most users.

When using YouTube system freezes between 5-30 mins, of start of any video. I have troubleshooted, i have checked every extension, i have run every diagnostics on hardware and software , checked and updated every driver but no results i tried checking online but didn't file any solution , the only thing i can do is to reset my system, it does not happen in any other situation. This is happening since the start of Oct'25, if anyone has any idea how to solve this kindly help.

I just want to know WHERE the notifications land? I have a very old macbook pro (mid 2010) so I have a sneaking suspicion firefox is trying to tell me something about not being supported, yadayadayada, BUT where are the notifications? The OS am currently using is High Sierra 10.13.6 CAN ANYONE HELP ME OUT HERE? Sorry to be such a klutz but these banners appear every day and I can't seem to access whatever it is that firefox is trying to communicate. Thanks all!

The Government has to keep changing. "for our Security". We have accounts with the Veterans Affairs medical stuff for our medical stuff. NOW we had to move to Login.Gov or another website. It was horrible, but I FINALLY got the Olde Marine & Myself 2 Different accounts (i.e. 2 different email addresses) in Login.gov. VA has continued making changes & since Friday I can not get into "My Healthy Vet

i.e. I go through the steps & when I type in the e-dress & password MY PHONE SHOULD RING with a numeric code.  Once I type in the Numeric Code, I can continue to scramble around trying to access our pharmacy or our 'care team' in the VA system.

I watch the screen, nothing happens. I wait for the phone call nothing happens. I look in my email box & there is a message from Login.Gov that a code was sent to me. NOPE.

I have no idea why. as a cat like nosy person, I am always needing to know why. What is wrong? Is it the government & if so forget it as they most likely won't answer the phone. Is it Charter Spectrum? Is it Mozilla Firefox? (whine) I am beyond my paygrade here. Please someone who can talk to olde Phartes... MAYBE this could be SPECTRUM/Charter??? They are a royal pain in the tush. sending mail to spam that is not & ignoring that I tell them it is real; changing font sizes when I am typing; & other crummy stuff.

Hi. I am trying to migrate Firefox from my wife's laptop to her new one, using sync. I've followed the instructions, set up sync on the old one, then set up sync on the new one with the same account. Nothing changes! Where am I going wrong? Or will I have to do a manual transfer instead?

I wanted to synch my current settings in my browser to import them on my new laptop. When I tried to login to my account, I the message from the attached screenshot appeared. So I created a new profile, got my stuff back to what it should be and then deleted the "new" profile. But now every time I try to get into the correct profile and login into my account, I still get the message from the screenshot. I never ever synched with another profile before and never had an issue in the past. Right now I am rather pissed off, because I lost atleast some of my bookmarks during this whole ordeal.

No accès, ils bloked, i got an iPhone, and thé y send you back to thé applications White its wrighting its open but if i click again send me to thé applications and same bla b’a bla..,

peter.lerche@mail.dk My internet service provider, YouSee, removed my access to Thunderbird for a couple of days - then restored it. However with the result that my laptop can receive and send emails, my PC can receive but not send, and my phone can neither receive nor send.

YouSee claims that everything looks OK from their side, and that any correction is up to Thunderbird.

Can you possibly help me?

My Spectrum password was changed and now I cannot get direct access to TB. For some reason TB is not linking up with Spectrum password. I get a popup panel saying "Login to server Mail.TWC.Com with username jomar159@hvc.rr.com failed" Retry Enter New password Cancel I have 2 accounts on TB 1 is wmarks1 and the other is jomar159@hvc.rr.com HELP

I have two Gmail email addresses. One is used for important messages. As of last Thursday I am not receiving some emails sent to this account. I asked sender to use secondary email and they come through. I’m very concerned that I’m missing important messages and need to get this corrected quickly. Please help if you can. If I need to delete Thunderbird I will but hope not.

Suddenly I am not receiving emails from my church and financial advisors (especially daily and weekly newsletters). They are NOT going into spam; I'm stumped. Appreciate your help.

In Outlook, it would say that "I replied to this message on xxx" in the header (not sure if that is what it is called, but near the top). I found it helpful to at least see if I have already replied to a message received. Is that feature available in TB?

Thunderbird is deleting mail from my inbox every time I download new messages. I double checked my settings and they are correct, so this should not be happening. How do I prevent it?

Hello all!

I use Thunderbird as a local archive for my email. I have two accounts in the application: my home email via my ISP (POP) which I predominately use and my gmail (IMAP) which I don't generally use. There are years of messages in folders and sub-folder under the POP account, but nothing under the IMAP.

I’m up to date with Thunderbird at v140.1.0esr (aarch64) on my iMac with Sequoia 15.8.

On 07/22/2025 I went to download some messages via my ISP POP account and saw that a whole bunch of my email folders no longer had any subfolders and were empty of any messages. Some were also duplicated. Please see the attached image.

I haven’t changed any settings in years, and I do not have any add-ins. One of the nice things about Thunderbird has been its solidity and simplicity.

After every session, I would empty my trash and compact.

Suddenly my email seems to be gone along with sub-folders while top level folders are duplicated.

Wondering if anyone has any suggestions on how to troubleshoot this? Since I don't do anything fancy with the application and with the suddenness of this issue, I can't image I'm the only person having it? I’m quite concerned I may lose many years’ worth of messages.

Thanks much in advance! CPRoot

Hi there,

For some reason, all my text has been showing up as bold on my Firefox web browser. However, the same sites do not appear as bold on the mobile Firefox app or in a private Firefox web browser.

While I thought it applied to many different fonts, it seems to specifically target Roboto. This is especially troublesome because my photography website has all body text as Roboto:

https://www.koby.photography

This was not always the case, but one day everything began appearing bold several weeks ago. Text that is italicized seems to stay in italics and not bold.

I greatly appreciate your help and support. Thank you in advance

A website has moved a while ago, but when I type in the first few letters, I still get the URL to the now defunct site suggested. I tried long-pressing the entry under "Firefox Suggest", but do not get any options to remove it.

Since the defunct URL starts with the same 10 or so characters as the new one, I always have to type a lot to get to the correct page. On the other hand, I use it to rarely to warrant a bookmark.
