In the last few days I am getting tabs crashing constantly (Gah. Your tab just crashed). This has never happended before. I have AVG antivirus and have downloaded the newest version of firefox. Is there anything else I can do to stop this happening.

I have been using Firefox for over a decade. My doctors systems use MyChart for communication with patients. All of a sudden, it takes minutes to load ANY and EVERY page. Their IT says it is Firefox is not compatible with MyChart. Why all of a sudden is it not compatible??? I don't want to use Edge or Chrome....especially edge.

When I try calling some of my Facebook friends from my PC, I get this message "Video calling is not supported on this browser " . But when I try calling other Facebook friends, everything works just well. When I try calling my Facebook friends from my cellphone, no problem.

My emails do not download into my email "in" box as they used to do. I get the following message when I try to log into my emails.

Warning: Potential Security Risk Ahead

Thunderbird detected a potential security threat and did not continue to live.thunderbird.net. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details.

Can this be fixed? Can you help me to fix this problem? Thanks, Michael.

Hi, I have been using thunderbird with two accounts. One day one account decided that won't get new messages, so I deleted that account, tried to add it again and it is showing me mistake: Unable to log in at server. Probably wrong configuration, username or password. I am 100% sure, that all the credentials are correct. Could you please try to help me?

Hi there,

I am tryign to access my firm's MetroBank account through Firefox and, after putting in my login details, I get a blank, white screen. I've tried with the same details through Chrome and it works. I've also disabbled pop up blocking and ad blockers.

Any other tips on what I could look for?

I prefer the Firefox browser. Outlook 365 used to open perfectly on my laptop, but it does not open now. Nothing different was done. I trouble shooted this with Outlook support, but it turns out that it is a Firefox problem.

Outlook 365 opens perfectly in Chrome on this laptop and on my phone and it still opens perfectly in Firefox on my old Macbook Pro from 2013.

What shall I do?

Hi team. Since yesterday, Thunderbird has stopped receiving and sending emails from both my accounts. Get this error message: Warning: Potential Security Risk Ahead. Thunderbird detected a potential security threat and did not continue to live.thunderbird.net. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details. How can I fix this? Regards, Tonia

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.

Hi I have asked a question about my new email account in outlook. I have set up a new identity with the new email address. I have set up an app in outlook. I can receive emails but cannot send them. Answer have apparently been posted but I can’t see the email thread either. I really need some help here please. Can the answer be emailed to me or at least a link to where the answer is posted on the thread. Thanks

I've tried downloading 2 different add-ons to replace loaded words in newspaper articles with more accurate ones. However, they are useless unless I can specify which words to replace. There used to be an option to edit settings for a particular add-on in about:addons, but it has vanished. Where can it be found now?

I use FF on PC.

History keeps showing in shortcuts,how to stop that?

Thanks

Hi,

Yesterday I set up a new computer, installed Firefox and logged in to my Firefox account. Everything went well, my bookmarks appears, all (!) my extensions were installed, everything looked fine. Then I went about my way configuring unrelated Linux stuff, using Firefox as normal on both computers, no problems.

But at some point, I suddenly noticed that on both computers, the icons for most of my extensions had disappeared. And sure enough, looking in about:addons, all that was left were five addons (Dark Reader, Simple Translate, uBlock Origin, Dictionary Anywhere, OneTab). And on both computers, including my main laptop (!), where I hadn't done anything other than clicking around in websites.

And it only affected the extensions, my bookmarks, history, etc all is fine and synced between the computers.

No restarting of Firefox, choosing different profiles in about:profiles (there was only one other, a mostly empty one), nothing got them back. And looking in ~/.mozilla/firefox/, sure enough extensions.json and all extension related folders had been changed, looking as if I never had more than these five extensions installed.

And when I installed one of my usual extensions again, all of it's settings and customizations were back to default. So this is not just a case of having to reinstall a few extensions. All custom uBlock filters, all Tampermonkey scripts, etc, everything is gone.

I tried looking around on the web for solutions, but it appears that there is no one who has had this exact issue before, and I couldn't find any indication that there is any way to revert such an error by Firefox Sync.

To my luck, I have a secondary laptop where I should have a mostly up-to-date instance of my Firefox profile, from which I will now try to recover my extension data, but if that weren't the case, years of fine-tuned settings and customizations would be gone.

As people rely on Firefox Sync to back up their Firefox data, instead of backing up their Firefox data "against" Firefox Sync failing like this, I'd think this is not something that ever should be possible to happen. At the very least, there should be some way to revert errors like this. Perhaps Firefox Sync could store backups either server side or client side before syncing deletions like this?

Hello! Since I couldn't find help in the forums, I will create a new question. For about a year now the PC at my work will not open mailto-links correctly. There is no account to select from, the subject has a lock-symbol. The receiver's address is correct though (I replaced it with "address" for the screenshot). This PC is the only one I know with that problem and only with external mailto-links. If I click on an email address inside a mail, it opens it correctly. Thunderbird version 115.11.1 (32-Bit), Win 10

It's pretty impractical, so I am hoping for help. Thank you!

When going from Help on menu to check for updates receive the error message - Failed to check for updates.

Running on Windows 10 with NAV - problem is recent in origin but I can't be exact as it's not my regular PC.

So far I've manually updated Thunderbird from 115.11.1 to 115.11.2 (64bit)by downloading from Mozilla website, rebooted from cold several times, and applied the fix from Norton:" https://community.norton.com/en/forums/auto-update-norton-360-v2449067835-now-causes-security-exception-thunderbird " in case it was related. It appears to be unrelated because on my regular PC the NAV update occurred necessitating the fix to the security exception error but don't have the checking for updates error.

thanks
