Using Firefox--When I try to access the daily set of images that comes in an email representing memories for this day which is pulled from my Onedrive Photos, all I get is a dark blank screen with a subtle pulsing wave as if it is searching.

I get the same thing when I go directly to my OneDrive Photos and try to pull up the daily photos there.

However, changing browsers and using Google Chrome--I can view the images in the memory email as well as those on my OneDrive directly

What does Chrome do that Firefox is not?

I recently had another browser related issue on a different problem trying to register online with Directv which would not complete with Firefox but when I used Google Chrome instead of Firefox, it worked.

This made me wonder if the above OneDrive image problem might be browser issue. Sure enough, it was.

I really prefer Firefox and I do not want to have to go to Chrome.

Hello.

My Firefox browser is missing the close button from the top bar. Minimize and Maximize buttons are present.

This is happening on Fedora 42 With Gnome.

I believe I don´t have any custom theme or user css or extension that could cause this.

Also because, it seems to be hapenning not only in Firefox itself, but also in Firefox based browsers, like Tor Browser.

Anyone has any idea what is hapenning?

Thank you.

Why am I getting this message: with no way around it?

Best regards,

At the beginning of 2025, I created a private theme and installed it locally (Windows 10), consisting of a manifest.json and a GIF file. It worked perfectly. Now, on Windows 11, I'm trying to use the theme again, but when I upload the file (.zip or .xpi — via about:addons -> Install Add-on From File), I always get the message that the file is corrupted. However, if I test it temporarily under about:debugging, it works immediately without any issues.

I would really appreciate a solution! <3

I am suddenly unable to login to my iCloud account using Mozilla Firefox. I was always able to do so before now. I am able to login using Microsoft Edge browser. I have disabled the Firefox pop-up blocker but still not working. When I input my username and password, iCloud sends me an authentication code... but that next pop-up screen from iCloud having a place to input the code does NOT pop-up, so I cannot enter the code. That pop-up screen comes up in MS Edge. Any help is appreciated!! I'm running Windows 10

When trying to print something using Firefox it automatically wants to print 2 copies, despite refreshing, rebooting, reinstalling and checking browser settings. This issue does not occur with other web browsers such as Microsoft Edge.

I am trying to set up a new computer. I have customized the homepage and new windows to a preferred page, however I cannot customize the new tab settings. The only options for a new tab are either Firefox homepage or blank page. I am trying to find a way to have my preferred homepage open when I open a new tab.

The website you are blocking is on my domain and is my website. Why are you blocking it? Stop blocking it!

Will Firefox ever be updated to use end to end encryption so that users of Facebook Messenger can do audio and video chats as they did before META's change?

If not, Mozilla could lose a lot of Firefox users of Facebook Messenger. That includes me. I have been with FF since v0.93 :-P

Messenger audio and video chats work fine on several other browsers including Brave. There is even a Messenger App on the Microsoft store.

I would really like to see someone at Mozilla answer this.

Hmm. We’re having trouble finding that site.

I am a Dropbox user. I have until recently been almost strictly a Google Chrome user. The PDF seamless behavior I have been seeing in Chrome is like this: 1. If I click on a search engine result for a PDF, I see the PDF opened in the browser. 2. If I click on Download at Dropbox, the PDF is downloaded to my PC.

On installing Firefox, the behavior I saw was like this: Whether I clicked on a search engine result or Download at Dropbox, I saw the PDF opened in my browser.

When I changed the Action for Portable Document Format (PDF) (application/pdf) and Portable Document Format (PDF) (application/binary)to "Save File", the PDF downloaded to my PC. But so did search engine links.

I seem to have fixed the issue by making my settings like this: 1. Action for Portable Document Format (PDF) (application/binary) to "Save File" 2. Action for Portable Document Format (PDF) (application/pdf) to "Open in Firefox"

Fingers crossed. ??? I was wondering why it wasn't set up this way on installation.

Every couple of minutes Firefox just freezes. YouTube buffers, all open tabs just stop working. I can open new tabs but i cannot search up anything or go into any websites. Is there any fix for this?

Windows 11. I have my taskbar behaviour set to ‘Automatically hide the Taskbar’ So usually the Taskbar is not displayed, but when I move my cursor to the bottom of the screen it reappears. With Firefox I cannot make the Taskbar reappear.

Have been having an issue for the past month or two where if left in the background firefox will slowly start to eat up my available ram. I was using it like this perfectly fine for years previous to now.

I dont have this issue when I'm actively using it, only when I tab away from it and specifically its not on screen. Once I tab back to firefox the ram usage immediately dips back down to normal. I have tried many things to try and solve this like doing a clean install of firefox, getting rid of extensions, clearing my browser cache, closing all other apps to verify it was just firefox, clearing my history, turning on hardware acceleration. Nothing seems to help, im really at a loss and I don't understand what changed besides it being updated in the past couple of months.

My computer is fairly heavy duty and I have 16gb of ddr4 ram that again was working perfectly fine to run firefox before these past couple of months. As a result of this issue however if left in the background for too long on accident firefox uses up all my idle ram and starts causing other programs to not be able to run and has even crashed my computer previously when trying to run a program like clip studio paint.

I have noticed that while running the firefox task manager there is definitely some difference in memory usage when i tab back in after letting it be in the background so I have attached screenshots of the regular usage while tabbed in and the captured usage when i tab back in.

Any possible solution is welcome because I really enjoy using firefox and i dont want to have to switch browsers unless absolutely necessary.
