I recently installed Thunderbird (115.10.1) onto my Mac (Sonoma 14.4).

After lots of manual housekeeping and deleting/filing hundreds of emails that had appeared in my inbox (that had previously been moved into other mailboxes or deleted) I have got my inbox down to a manageable size.

But now four of the emails in my Gmail webmail inbox are not showing in my Thunderbird inbox.

I have run a repair on the folder (Thunderbird inbox) but the discrepancy remains.

How can I make sure they synchronise correctly?

Also: I have 4 old drafts in my Gmail webmail drafts which are not showing in my Thunderbird drafts folder. I created a new draft email in Thunderbird and it is not showing up in my Gmail webmail. I have tried to point Thunderbird to my Gmail drafts folder in account settings selecting: copies and folders/drafts and templates/other/drafts on [myemailaddress] but it does not seem to make any difference.

Any help much appreciated.

Every time I sign onto Firefox I get the attached message. I think that uninstalling Firefox and reinstalling "may" resolve the problem, but Firefox won't uninstall. I have tried four different ways and it won't uninstall. Can you help me an uninstall process?

I have a 2019 Macbook Pro 16" and whenever I share a FireFox window on facetime, I'm unable to stop sharing it until I end the Facetime call. Even then, the sharing screen notification still appears in the top right in the menu bar and I'm unable to share my screen for future Facetime calls unless I restart my laptop (thus removing the problem). Is this a known issue, and is there a way to fix it other than restarting my laptop?

Recently, I reported a glitch with e-mail messages from you. The text of the messages was darkened either completely or almost to the point of being unreadable--actually, backgrounded--always at least partially covered by a pop-up telling about the trackers that were derailed by the DuckDuckGo browser. Since then, I have made a discovery: The problem occurs when using Apple's iPhone Mail app, but not at all when using Microsoft's iPhone Outlook app. It should be noted that e-mails from you go to my Microsoft (Outlook.com) account. I hope that helps.

I have been using Firefox on my Mac for years with no problems. Recently, however, I have been having trouble running YouTube. I get to the correct page for the video I want but the video itself does not show up, just the background for the page. Any idea what I might have done to create this problem?

Just transferred from old MacBook Pro to new one. Successful migration except: The icon for the WE Transfer service doesn't show up in the narrow black ribbon at the top of the Firefox page - instead there's a blue exclamation point in a blue circle. Clicking the blue circle/exclamation point takes me to the WE Transfer page. What do I need to do to get the actual icon to replace the blue circle/exclamation point? Thanks in advance.

So for some reason I have two versions of Firefox on my computer (Windows 64 bit), I am logged in and using one of them, and the other is just there. I could log in there but I don't want to, I just want to get rid of it. Links from Telegram open in it, creating a second Firefox window instead of opening in another tab in the already open Firefox window, which is very inconvenient. The windows list of programs which can be uninstalled only has one Firefox (I've tried deleting and reinstalling, it doesn't help). But when I try to choose a default browser I get 2 icons to choose from which look the same (see screenshot). What the heck? How do I manage this!

Hello,

Firefox currently does not prevent macOS from going to sleep when a download is active.

How do I know this? 1) I downloaded a file from the internet. 1.5 GB in size. 2) I opened a Terminal window in macOS, and ran `pmset -g`. 3) I searched for "sleep" in the "Currently in use:" list, and checked if Firefox was listed. It was not.

Is there a setting that I can enable that I can download to make this happen?

I think extensions don't have the capability to prevent macOS from going to sleep. Correct me if I'm wrong.

A quick fix for now would be the `caffeinate`-command in the Terminal-app, but I think this is very resource-wasteful.

Thank you in advance! Kind regards.

Hi there,

I just started using my new MacBook Air, and when I try to use the trackpad to open read Gmail or click the calendar icon on Firefox, it doesn't respond. It works on Safari.

As per the photo, I try to click the calendar icon to open up my calendar and nothing happened.

When switching from one tab to another, streaming stops and video won't play in background. I've tried all the main fixes suggested I've found. Nothing worked. Please help! Will be using alternate browser until fixed as it's too unwieldy for me to use this way.

Hyatt.com can be loaded on other browsers but not on Firefox. There is just a blank page with no error message. There is an archived thread on support.mozilla.or called "hyatt.com". The suggested solutions don't work or are too complicated. So please solve the problem. And STOP archiving threads that are still an unsolved problem! Am using Win8.1 and auto-updating Firefox.

I have been living a battery drain issue in background. When i do not force stop firefox manually, it just continues to drain some percentage of my battery while my whole usage. Like 10% to 30%. It's worse when i turn my phone off and sleep. Firefox drains all of my battery while i sleep.
