I'm on a Mac running Monterey 12.7.4. I've been using Firefox for years with no issues. All of a sudden Firefox can't load any websites. Message: "We can’t connect to the server at www.XXX.ca." But Safari loads all websites with no problems. I can't figure this out.

Hello, I am trying to send emails from my iCloud account and it always fails due to the SMTP server timing out. I've tried making a new app-specific password, deleting and re-adding the account in Thunderbird, and made sure the authentication settings are right, but it still doesn't work. I can connect to the IMAP server just fine.

After importing events from the old ics calendar into the existing CalDav calendar. TB sent invitations out to all attendees, even for past meetings. How to avoid this?

The latest version of Thunderbird has lost the Advanced Search button. I can still access it from Control/Shift/F so the function is still there, but no obvious way of accessing it

Since the update to version 125 Firefox on Windows 11 (all updates installed), when I open a new tab and start typing to the address bar WHILE the VPN to the office is active, Firefox locks up and can not be used anymore.

In taskmanager, there is no spike in memory or cpu usage visible. All I can do at this point is to kill Firefox via taskmanager.

I can enter anything in the address bar of an already open tab with an other website open, I can open new tab from the bookmarks, but I can not open a new tab and start typing in the address bar while the VPN is active.

Once I disable the VPN to the office, everything goes back to normal.

I never had this issue on a previous version of Firefox.

Any ideas whats causing this?

Hi, i just got a new laptop (Asus Zephryus G16, 2560 x 1600 screen) and after installing Firefox there is a thin white border to the left of the screen when running in fit screen. This problem is not present when in a windowed mode or in F11 full screen.

I tried updating the Intel Arc drivers but this did not fix the problem. Changing to compatibility mode also did not fix te problem.

PS: in the uploaded screenshots it is quite dificult to see the white line(because the background is also white), but when the image is viewed in a new tab it is visible.

Thanks

I recently purchased a new laptop and needed to migrate my old Thunderbird profiles. This is what I did: 1. Backed up profiles from old laptop 2. downloaded and installed latest version of Thunderbird on new laptop 3. coped profiles into \roaming directory 4. tested and successfully received emails and viewed all old emails.

The problem is that the Mail toolbar is nowhere to be found. Also, the calendar is missing. I tried right clicking on empty space and it only showed "menu bar" as an option. Attachment shows nothing in the toolbars option of View dropdown.

I have 6 accounts on cox.net and today in two out of the 6 accounts, emails that I send are not saved and I get a message "Your message was sent but a copy was not placed in your sent folder (Sent) due to network or file access errors. The "sent" folders for these two accounts are grayed out. I have verified that the account settings have the right folder as the destination for the sent emails and have checked that all emails should be saved. I also get a message in Thundebird -The current command did not succeed. The mail server for account xxxxx responded [TRYCREATE} Mailbox doesn't exist. Mail goes out but no copy is saved. Only two out of 6 accounts are affected and I didn't do anything to them before this started happening.

I am using Firefox v125.0.2. When I open a PDF in Firefox it takes a lot of time to load. But, when the same PDF opened in the Edge browser it loads normally and scrolling through PDF pages renders fast. I have shared the screenshot of a single-page pdf loading taking quite a long time.

Could someone please help me with this.

Using windows 10, windows firewall, windows antivirus, Thunderbird 115.9.0 (32-bit)

Can't send from Optimum accounts.

Error message "Sending of the message failed. An error occurred while sending mail. The mail server responded: Spam detected by content scanner. Message rejected (ID 661FD756017B2BC6). Please check the message and try again."

Check outgoing server setting, tried changing authentication method, but got the same error.

I am struggling with Gmail and Yahoo mail account in TB these few days. I hit almost the same errors from both. I generated app password for Yahoo mail, and put it in when setting up new account. For connection security: SSL/TLS For authentication method: tried with Normal password, Encrypted password, and OAuth2 However, I am seeing the expected authentication window pop up when trying the OAuth2. For all three authentication method: errors are always the same --- unable to connect to your IMAP server. I've followed another instruction to change maximum number of server connections to cache into 1 or 10. Error messages were the same imap one. So, what should I do/try for next?

I had a few issues with Hotmail and Firefox in the past as described in other posts. Now it has stepped up a gear. I can use the internet for anything, but the moment I open my Hotmail account in Firefox my Lan card stops working. At first I had no idea it was Hotmail, I tried everything from switching cables to using wifi only. When it happened on wifi I realised every time I went into Hotmail on Firefox my network card stopped functioning and I had to restart the computer. The thing is, when I use Hotmail through Microsoft Edge nothing happens and all is well with the world!!! No network card shutdown. I could read between the lines but I'm no conspiracy theorist, however, I don't think the problem is with Firefox. Is there any solution? I don't use Edge and I don't want to start.

Hi,

There many extensions such as:

https://addons.mozilla.org/en-US/firefox/addon/search-on-imdb-context-menu/ that say when trying to install:

Installation aborted because the add-on appears to be corrupt.

I am using Firefox Developper Edition, with extensions.langpacks.signatures.required set to false.

This addon, after download, installs fine as a temporary addon.

How can I install it permanently?

Thanks.

I have been struggling with slowness in Thunderbird in recent months (Windows 11, mid-range Lenovo laptop). There is often a distinct lag during even the smallest operations.

Examples are: selecting an email, closing a tab, typing, calendar events editing.

TB process in Windows usually uses 1000MB RAM. RAM is around 60-70% usage usually. I never have the same slowness issues with other applications.

I tried quite a bit: safe mode testing, removing extensions, compacting folders and more tips. I ended up removing Thunderbird and my profile entirely, and reinstalled the latest version with an empty profile. I just set up my Gmail and other email account. No extensions installed, yet still the same issue.

Could it be that something is still there from a previous install, if I removed my profile?

I've been using Thunderbird in Linux and Windows for years with moderate issues that I was able to resolve, but am now really puzzled. Please help.

My Browser keeps on telling me there is an update... I've updated, reinstalled the latest version and it still keeps giving a pop-up saying there is an update...

How do I get rid of these pop-ups???
