When I'm sending attachments in Thunderbird some of my clients are recieving the email but not the attachments, though when they look on the phone they can see the attachment ?

What can I change in my outsettings for attachments to solve this issue

All downloads I make inside of Firefox are automatically failing, with "Failed" message. This only happens in Firefox, Microsoft Edge downloads are perfectly fine. I've tried starting in troubleshoot mode, disabling anti-virus, clearing cache and downloads, rebooting PC.

Some recent changes in PC include: changing TEMP and TMP system variables to another drive (I've changed them back to C drive, had no effect) and making C drive a dynamic disk. Yesterday downloads were working fine. Thanks in advance.

Hi, first the last update tried a few times over some days to install. Never got confirmation that it has been installed successfully. When I go to "About Firefox" I'm getting the information that I'm using the latest version.

Now I have problems, mainly when using facebook (especially when I try to play games through facebook) that Firefox uses enormous amounts of CPU and Memory. This does not happen all the time but at least in 70% of tries. I attached 2 screenshots

If this happens I'm not able to close Firefox the normal way but have to kill the process in the task manager.

Any quick help would be appreciated. I would also like to know if I'm the only one experiencing this or if it's a common problem.

My customer has a problem since about a month on Firefox (using it on a Terminal Server). The top of Firefox gets hidden by white and grey "bar" and he can not even use the "functions" of buttons behind that. -> Please see attached Print screens Lower part of the Favorites-bar is visible and also works if he clicks on it - everything above not visible and does not work for clicking.

The problem only comes up from time to time maybe once or twice a week. When he minimizes Firefox the application behind is visible normally. when he maximizes it again, same problem still visible in Firefox. When he closes RDP Session and reconnects - the problem disappears. When he turns off the monitor where Firefox is visible - Firefox gets move over to the other monitor and the problem disappears.

I am not 100% sure if this is a Firefox problem or Remote Desktop Problem (or maybe an add-in problem). But until now it only happened on Firefox!

He is always on the last recent version of Firefox, we just updated today to the latest version again - but I can not say yet, if the problem would still exist on the latest version from today.

I recently updated to 125.0.1 and now get 'failed to check for updates': - when I manually check (help > about Firefox) (see image) - in 'settings' it also shows 'failed to check for updates' (see image) I never had such a problem with previous versions; any suggestions?

Thru Firefox, I use Tineye to find related photos - I use it all the time, it's been great - I always use a VPN and have never had problems until now (as of yesterday). Now it won't search, a verify you're human window comes up, and I have to keep clicking squares, which I do - but then it says to allow cookies and start over. Well I don't want to allow cookies (I assume it's one of the options I have thru Firefox to block cookies), and I can't find where to allow cookies even if I did (I went to Firefox preferences etc) and I don't want to disable my VPN. Maybe I should mention that I just added or started a Mozilla account, as I have had immense trouble with my aol emails, and am trying to move everything over to a gmail account. My sign in to Firefox was the aol email, and I had to (try, I thought I did it) add another account, which I think I did successfully. So it was right after that, that all this started. Help please! Thank you!

So this problem keeps happening to me - I click "upload" on a website and nothing happens. For example, trying to upload photos to my website or upload files to a platform. Frustrating. To work around it I've been using a separate tab of Google chrome but it's such a pain to keep swapping back and forth. Please help!!

I keep getting notifications asking me to update firefox every couple of days. I download the update, it goes smoothly, the notification disappears, but it comes back in a day or two. I also have my setting to supposedly do updates automatically, but that doesn't seem to be working. Please help!

Hey folks, I've been noticing something peculiar with Firefox that's been bothering me lately. Whenever I try to watch videos on YouTube in resolutions above 1080p, they tend to randomly buffer. It's quite frustrating, especially when I know my internet connection is stable and other browsers don't seem to have this issue. Has anyone else experienced this problem with Firefox? And if so, do you have any tips or solutions to share? Thanks in advance for any insights!

I cannot open any Games on the NY TImes site with FIrefox for the past month; no problem with Chrome. Today, two article links opened but then the page went blank (repeatedly), while other links worked fine. Again, no problem with Chrome. My wife can't get into proxyvote.com with Firefox--again, a blank screen. Where is this weirdness coming from?

My yahoo homepage on firefox looks totally different than it did last week. Chrome and edge still look like the home page should but firefox does not. I screen shared with yahoo and they said it was a firefox issue. Anyone know how to make the homepage look like chromes and edge? I added pics from edge and firefox for comparison.

Howdy,

Workflow: I have a firefox instance already running. I want to launch a new firefox in safe-mode to test something without disrupting my existing firefox.

Problem: I try to launch a new firefox in safe mode using `firefox --safe-mode`, but firefox just opens a new window NOT in safe mode.

I think it may because firefox in safe-mode requires launching launching from a new instance rather than attaching to existing instance.

`firefox --help` shows a flag I can use:

--new-instance Open new instance, not a new window in running instance. --safe-mode Disables extensions and themes for this session.

So I run `firefox --safe-mode --new-instance`

now I get error popup with message:

"Firefox is already running, but is not responding. To use Firefox, you must first close the existing Firefox process, restart your device, or use a different profile."

Now I think what is the point of the flag "new-instance" if Firefox doesn't support multiple instances?

Regardless, how can I launch firefox in safe-mode without disrupting my existing firefox instance and without relying on creating a profile just for this?

With the exception of the Home and Catalog pages in the yotsuba theme, all boards default to black and only on Firefox, not Safari or Chrome browsers.

Any idea how to fix this? I'm looking to get back my default Yotsuba theme.

I have enabled Firefox Sync between my laptop and my Android. When I go to the manage history tab on my laptop, the history of both my laptop and phone is shown but without the device the tab was viewed on. Is there a way to filter history based on which device I viewed on?

Firefox sometimes continuously adds tabs for the same site I am using. Every time I X out of one, another one pops up. This multiplies alarmingly fast. I have Windows 10.

I use a MacBook AIr with OS 14.4.1 (Sonoma) and want to add a short cut link to Proton Mail (Free version) that I can put in my MacOS Dock. I am using Firefox 125.03 version.

I used to have a link in my Mac Dock but then I tried the trial of their desktop app-- and when that ended recently, I did not know how to set the Dock link up again. I tried directions for other browsers but they did not help.

'The link I want the short cut to go to is' https://account.proton.me/mail so I can sign right in to check my email.

So I checked Proton's support site for help but it has directions to do this ONLY from Safari and another browser, NOT Firefox.

If you can give me some straightforward directions to add the shortcut to Proton Mail sign in back to my Mac Dock, I would be grateful!

I really enjoy and feel safer using Firefox, by the way! thank you
