Reposting until I get help from someone. Windows/desktop. On Google Chrome, any streaming website I used with autoplay enabled would KEEP full screen mode ON after changing episodes. It would automatically go to a new page with the following episode and remain full screen. Why doesn't Firefox have this feature?? I'm seriously considering going back to Google Chrome for this one small feature. Every time I had any streaming service playing with autoplay enabled, I didn't have to manually select the full screen option every time. I am having to stand up and manually click full screen function. Every. Single. Time. Somebody please help me if there's a way to active that function.

I was happily using TB 78.14.0 on Mac OS 10.9.5 and I switched to using TB 140.6 on Mac OS 12.7.4, and it's now unusably slow. I've tried: troubleshoot mode with add-ons off; compacting folders; removing and renewing msf files; emptying junk and trash. Is there anything else, or is this just a failure or incompatibility of the app? I can't see that there's any antivirus app that might be interfering. Can something go wrong when you export the files from one TB into another? I would be grateful for any suggestions. Tim

I believe I found a bug. When drafting an email and switching away from Thunderbird the draft email gets sent but still remains in the drafts folder.

I created two emails today and had to switch away multiple times to get some information to paste into the emails. Thunderbird evidently sent out the draft in its current format whenever I switched away from the app.

I sometimes want to give Message Labels two different colors. But it stays in the first selected color. It would be great if, regardless of how many I select in the Message Labels column, they appeared as small boxes with their colors (like Outlook). The current state might be good, but with multiple options, the list view mode and the reading view mode seem illogical.

In short, the same colors as the multiple boxes in the Reading section should also appear in the mailing list.

I think that's how it should be logically.

Hi folks, I set up mfa on my Firefox account a while back using Authy but now that I need to redownload Firefox for my mobile device I have forgotten my Authy PIN and can't seem to find the account recovery keys anywhere. I may have lost them because of only storing the recovery key and pin record locally on a device I have since formatted and sold. It looks as though it's very difficult to recover via Authy or perhaps not possible (I have one mobile and laptop and Authy has discontinued the desktop app). Is there a way to reset the account so that I can set up my 2fa again and this time keep the access info in a safer and retrievable place?

The last Firefox update to one of my Windows 10 machines was to 115 (which I thought was only for Win 7 & 8 installs). When I review the Help/About screen it is requesting an upgrade to 128, but 146 is the latest release. The ESR release for Win10 is 140.

After the latest (mid-December) Windows update destroyed so many things, including the sizing, movement, and display of Firefox windows, I'm freezing the automatic Microsoft update sequence, and installing the ESR 140 release as well.

Just trying to understand how Firefox determines which update level a browser will automatically download and install based on an existing, standard or ESR, release it finds installed.

Thank you.

Mozillers,

I depend heavily in my environmental and other work on Firefox and am grateful for its ability to restore previous tabs when my laptop, not infrequently, stops working abruptly.

Now the much-used bookmarks have disappeared. A search site states promisingly:

"To restore Firefox bookmarks, use the built-in backup feature by going to Menu > Bookmarks > Manage Bookmarks > Import & Backup > Restore, then select a dated backup or a manual file (like a JSON backup) to bring back lost bookmarks..."

But my Firefox's Bookmarks drop-down menu has no Manage Bookmarks option. PLEASE, what must I do?

Elsewhere I managed to find this file which apparently contains recent bookmarks:

"C:\Users\User\AppData\Roaming\Mozilla\Firefox\Profiles\unk14jlv.default-release-1647366062305\bookmarkbackups\bookmarks-2025-12-26_95_4IdGtYxezJpwuH1UIiT1bRwe1K6bcGO8rv0mqa9rUWU=.jsonlz4"

But attempting to open it with Applications\firefox.exe (default) accomplishes nothing.

FOOL-proof instructions would be wonderful. Thank you.

I successfully installed Thunderbird version 146.01 in November 2025 and successfully completed the connection to my email server Comcast.net. With all folders downloaded I proceeded to receive and send emails without any issues until around December 17 2025 when Thunderbird stopped receiving or sending emails. I performed all the steps listed without success, When I test the connection in settings I get the following: "Successfully established a secure connection to imap.comcast.net:995." Yet I get no emails

I see a Thunderbird update came in around December 17 2025, maybe a coincidence? Thank you Ed

Still not always saving a page to my selected folder. However, if after clicking the "Star", I first select the location "Show your bookmarks", then to back to to selecting the folder into which I wish to save the page, it will then put that page into the folder of my choice. What settings do I need to have in place so that I do not have to do this double step to get the system to save a page in my selected folder? Let me know if I should just start over, uninstall Fire Fox, I have saved all my book marks and exported in the two formats, then reinstall the program. Thanks in advance for any solution. JJE
