All Products Support Forum

For some websites, mobile browser stops responding, ironically I was on the support page only when it happened. It was lenovo support page, if you want to know, I can give specific page.

I like Mozilla so I thought just to bring this in your notice so you can try to make it better.

Thanks to development team from a developer.

I have enabled https-only mode, but now Firefox is warning me against accessing various perfectly OK https sites, e.g. https://www.totalenergies.fr

Since upgrading to 91.2.0 (64-bit) I've been having multiple issues on a daily basis. I've tried repairing and compacting all folders, to no avail.

I have Windows 10 64-bit version 21H1, build 19043.1288 with 64 GB of RAM.

Images are attached for the first three.

Sending email: The "Sending Message" dialog pops up, the progress bar reaches 100%, and it hangs. I click "Cancel" and get a message that the message either couldn't be sent or couldn't be save to the "Sent" folder. This generally happens when replying to an email.

My inbox show no unread email, but the folder name in the "Folders" panel is highlighted, indicating unread email.

I select an unread email in the inbox. I have the reading pane open at the bottom of the window and can see the email. The email does not get marked as read. The Folders pane does not update to reflect that the email has been read. I have Thunderbird set to mark messages as read immediately.

It can take a very long time to load a new email, particularly if there are embedded images.

Thunderbird does not seem to be synchronizing properly with my email accounts, which are all set up as IMAP. I'll get messages from my email server that my quota is reaching it's limit, even though I delete messages on a regular basis and purge the Trash regularly. My account has a 100MB size limit.

Any suggestions would be greatly appreciated.

Thank you.

Clicking on Firefox "Help" directed me to an odd "Crowdicity" website. This is rather worrying and makes me feel that I can't trust the browser's security anymore.

No calendar data showing after upgrade. calendar-data folder has local.sqlite which appears to be intact with all previous calendar info but nothing displays. I added a test event and it appears. The alert appears at the appropriate time but the alert cannot be dismissed. When I restart Thunderbird the calendar shows empty again but I can see that the new test event is present in local.sqlite. See error console below

I have a recurring problem with Firefox warning me that a perfectly safe https site is http and temporarily barring access until I confirm that I want to risk proceeding to it. The latest site to get this treatment is https://bloctel.gouv.fr/, which is a French government website. This is extremely annoying. How can I fix it?

Hiya, So I have used the link below as a guide to get firefox to autoupdate on users computers via GPO.

Firefox is now crashing on multiple Computers, I think they might be crashing while trying to update themselves, as per GPO.

Any help please , crash report attached

So one of my Thunderbird profiles stopped being able to send emails. Hit the send button and nothing happens. One of my accounts in same folder is greyed out.

I have tried reinstalling, cleaning up profile, rebuilding folders. Updating did not work and I think that may have broke it (versioun 91.2 x32)

Restarted with no add ons, checked language. Tried a different SMTP server, nothing works. No error at all. Windows 10 64

I originally had the latest release version of Firefox but started to experience issues with certain banking websites, and misc printing issues. So I decided to downgrade from the release version to the extended support release.

I uninstalled the release version, and went into the Appdata folder and deleted anything Firefox related. Then I installed the ESR version. It worked fine for the day, but a restart the next day, I discovered that my install changed from ESR to the release channel. I once again went through the install process mentioned above, and the next day, the same thing happened. Any idea on why this might be changing?

Note: I have tried both the MSI and .exe versions and experience the same issue. I am the only one that logs into this workstation. This workstation is actually a Azure Virtual Desktop with a variation of windows 10. (Screenshot attached with the OS).

Thunderbird 91.2.0 automatically updated (also updated from 32 to 64-bit).

The contact list in Write new email & the Address Book are blank and non responsive. However, the type ahead still correctly fills in information from the address books. I was able to copy all my addresses to a text file using the type ahead (a, then b, then c, ...). I cannot create a new contact, or new address book. Search in Contacts & Address Book returns nothing.

Everything else seems to work fine, except that I can't send email (nothing happens when I click send)

I restarted my WIN-10 computer - no change. I completely uninstalled Thunderbird, then downloaded and reinstalled - also no change.

I am increasingly having to use Microsoft Edge when using form based pages 2 recent exmples in UK are Boots.com booking flu vaccination - works in Edge not in Firefox and Argos.co.uk paying for item by card dropdown box does not support 4 digit year and hence everything gets declined)

Can you sort this out - it is not the only thing I have had problems with - always on form based pages (this also happened on NHS UK) and it ALWAYS works on MS EDGE

I am trying to fix the loss of my calendar and am using the following off your site.Lightning disappears after a Thunderbird update (release and beta versions)

This may happen if the update of the add-on is stuck. Don't worry about your calendar data, it is left untouched and will be available again if you follow these steps to restore Lightning:

   "Go to the Advanced section of Thunderbird OptionsSettings and click on Config Editor...
   Copy or start typing extensions.installedDistroAddon.{e2fda1a4-762b-4020-b5ad-a41df1933103} into the search box
   When extensions.installedDistroAddon... is listed in the preferences list, right-click on it and choose Reset from the context menu - the preference now isn't bold anymore and its value is empty
   Close the editor, leave the Thunderbird options, open Thunderbird's add-ons manager and switch to the list of installed extensions
   If Lightning is listed there, click on Remove to the right of the list item
   Restart Thunderbird"

After Thunderbird has been relaunched, Lightning will be back and you will have access to your calendar data.

When I key in the info required from above the extension is not listed. Does that mean that since it is not there that I can continue with the directions and the calendar will appear?

When scanning a barcode with our software accessed through Firefox, does not capture the barcode accurately. The mobile device has a built-in scanner. This is observed in Firefox 93.2.0 in Android devices. Do you know if this is a known issue?

I cannot invite attendees to meetings, except in troubleshoot mode, since latest update. There used to be a list of spaces to invite people but now there is nothing there. If I go to troubleshoot mode it looks like it did before the update and I have to keep resetting it to set up meetings.

First of all I don't know if i choose the correct topic.

My issue is that I like to help researchers by filling/doing their online quiz/forms/etc. They usually use this site for reflex test: https://pavlovia.org/ My problem is that you need to strike a key. Whenever I do that the f3 research box appears ... It's fun when you need to close it for a reflex test where seconds do matter. Is there a way to disable it ?

I forget my account password so i reset the password. Then i accidentally skip the recovery key to reset option so my whole data in sync is not shown. But i have a recovery key. How to restore my data?

Hi all,

I am a Linux user (Manjaro) and I've been using Firefox for ages now. I got hold of another computer recently, and I just installed Manjaro Gnome on it as well. I started Firefox, and suddenly I see a UI change, which I don't think is an update, but who knows. In this version of firefox the search bar (along with the new tab, refresh, pocket, etc buttons) are abobe the tab list (which spans the full width). You can see it here https://imgur.com/a/idqp5jb

Moreover, i tried changing themes via the Add-ons Manager and they can't be applied.

When using the Troubleshooting mode, Firefox is back to normal! But in normal mode it is not, so I am not really sure what the problem is. I would be thankful if you could tell me how to fix this.
