I’m currently facing a very frustrating issue with Firefox. I have been using Firefox for many years, and it is my favorite and most comfortable web browser for my day-to-day work. I rely on it heavily as all my bookmarks and other important details are saved there.

However, over the past few weeks, Firefox has been crashing more than 10 times a day. I have already tried all the troubleshooting steps available in the forums and through AI support, but none of them have resolved the issue. I also tried installing and using the Firefox Beta version, but the problem still persists.

In our environment, other users and devices are not experiencing this issue, so it does not appear to be related to internal firewall or antivirus restrictions.

Could you please help me troubleshoot this issue? I am attaching the error screen that appears after the crash along with the crash report for you

Long Delay occurs loading multiple websites, from facebook to other sites and I often get a delay of over 20 seconds with any site involving a CDN connection of various types. I am using W11, latest version of Firefox. 148.0 (Says latest version)

When it happens I can see the connection url in the bottom left hand corner includes a CDN part. Settings are Proxy settings "Use system proxy settings"

• DNS over HTTPS is set to "default protection"
• IPv6: ISP is has just changed from gigaclear fibre to toob fibre, but it has made no difference.
• Have cleared cache. No change

This is very frustrating. Started a couple of months ago. I have ended up using Chrome ratherthan Firefox and I am close to giving up with firefox. Help appreciated.

I can't seem to locate how to activate the microphone in the AI sidebar. I have Gemini selected, and when I hit the microphone to dictate I get the following message.. Unable to access the microphone. Please check settings.

I looked through Firefox settings and my laptop's but I don't see where it is turned off or asking for activation.'

Firefox displays garbled characters, but other browsers do not display garbled characters on the same website.I'm sure it's not a website issue, because more than one website is experiencing garbled text problems. We tried solutions found online, but none of them worked, including completely uninstalling and reinstalling Firefox.

This happens each time I open up T-Bird. Somtimes it is Yahoo.mail, sometimes it prompts to log onto aol.mail.com.

How can this be stopped?

Normally, I can right click and tell Thunderbird that this is NOT junk, however, when I do this, these emails go back into the inbox and virtually instantly return to junk.

This is from anyone's email address that arrives from one particular website: @legacydigitalagency.com

I haven't come across this issue since I started using Thunderbird 20+ years ago.

In our organization we have moved from an on-premise mail server to M365. We've also added our new EWS-based accounts to Thunderbird. Since there are a large number of users with a significant amount of older mails they want to have access to, they have been asking how they could upload them to EWS now.

From the looks of it, using TB one can either drag and drop messages from the local folders to EWS. Would message copy/move from the local folders be faster if the EWS account was setup over IMAP, instead of over EWS? If so, we could setup another account corresponding to the same EWS identity, but over IMAP, just for the purposes of transferring messages faster.

Thanks in advance for any information provided.

On my PC - Initial problem was T-bird took forever to load and virtually all new msgs went to TRASH and I had to move to IN-Box. Per help from David - Saved off profile, and reinstalled thunderbird from thunderbird.net. No change. Then UNINSTALLED T-Bird (profile still intact). Now just attempts to open "Looking up imap.comcast.net", but won't open/connect and to close the app I must use WIN Task Master. Can't get to any msgs, etc. Also, in the past when I was able to open, the banner or bar at the top of the page had hundreds of email icons. I sometime have over 1000 emails in my in-box!! I have years worth of emails in folders on T-Bird which I don't want to loose. Help. Thank you. I have a "working" version (with the "trash" and slow loading issue per above) on my laptop, so I can access suggestions on that version of T-Bird. You could also send any suggestions to x@gmail.com

Previous solution: switch browser.newtabpage.activity-stream.improvesearch.handoffToAwesomebar to false does not work anymore.

Please help.

Thunderbird has been working OK. Now, despite PC restarts and so on I get the message "mail couldn't be sent, time out error for SMTP server. I have tried changing the SMTP settings from port 465 to port 587 but no difference. If I log in to my email provider (vodafon/uniymail) I can send mails no problem. The problem is with thunderbird not sending smtp. Tried turning firewall and antivirus off, no help. Internet connection is glassfibre, internet works OK.

Apparently MS has changed something in their OAuth2 and Thunderbird has yet to catch up. I've seen several other questions regarding this, but no workable solutions, just silly replies. Is TB actively working on a solution or am I now forced to install Outlook?

At one time before several updates ago, all messages in my inbox were separate. After a previous update, reply or messages with the same header started be be nested, each one showing only the sender and the subject, which is now the same. I am forced to read through them all to find the one I want. Deleting any in the change can be hazardous.

How to go back the old way of message display?

One of my two outlook email accounts no longer appears in Thunderbird, which says it is authenticated but not connected. This happened suddenly. I can still get the messages by going onto outlook.com. How do I get it back on Thunderbird?

I am using Firefox on a W11 64 desktop. Until recently (the most recent upgrade, I think) all worked well. But since then although the relevant box is ticked in settings (aboutpreferences general), on opening Firefox the tabs from the preceding session are NOT restored. This is extremely inconvenient.

Have any others found this same problem? Any work arounds?

I've used Thunderbird for years & have never changed my password. All of a sudden, it will no longer recognize my password. As a consequence, I am no longer receiving email and cannot sign in, even though it just "updated" my version of thunderbird..
