I recently installed Win 11 on a new Acer Aspire (with MSI MAG244F monitor) but the issue seems to be present on my Acer Nitro 5 with built-in monitor as well.

I don't think it's an Acer issue but I am only running Win 11 on the two Acer machines. If I open a web page with colored graphics or pictures and then drop down a menu of the browser (bookmarks, etc.) the colors of the graphics bleed through. It's annoying and somewhat obstructive. It does not occur if a window from a different app is opened on top of the browser window no matter how bright the colors are.

I attached a few edited screenshots to show the issue. The edits are only to cover personal information etc.

The issue seems to be color saturation and does not occur on my other Win 10 machines or in other browsers. Not even the same version Firefox on the Win 10 machines.

Is there a way to increase the opacity of the drop downs or lower the color saturation in the Firefox browser?

I was customizing my background by loading a picture. It's adult in nature. It should be my computer in my in my private home. When something amazing started happening. If I load ANY image with a naked woman on it After a few minutes Fire fox auto removes it. I have done this 30 times. I use ANY fire fox picture it's fine stays there forever. Load ANY picture with a naked woman on it and poof 2 minutes later it's gone. So please can you explain to me why whats claimed to be the most private and secure browser around is censoring me in my own home about what backgrounds I can have? I find this highly disturbing. And I am quite serious I have had them removed at least 30 times. I'm 56 y/o If I want a naked woman on my background it should be my business not fire foxes. Also no chrome is not doing it. neither is windows. It's Firefox removing them. Any explanation would be nice.

Hello, editing Bookmarks is a manual process within Firefox Bookmarks. I would like to export sub folders and edit them on my preferred desktop text editors, then re-import said edited Firefox Bookmarks folder.

I have tried Firefox sub folder:

• dragging and dropping to Desktop, however fails
• copying/pasting to Desktop, however fails
• AI promises the world like a conservative politician's gish gallop, but nothing works and wrecks the current setup.

I have exported the entire Bookmaks.html file, however editing html to text, then somehow only text remained without urls. So now I have restored from an old 3rd party's bookmarks and need to clean what Bookmarks are left. Sub folder management would be easier than entire Bookkmarks.html.

I can't re-open a saved tab group. I saved it and closed firefox but when I returned I couldn't find where to access it. I see all of my saved tabs when I right-click on a tab and choose "Add Tab to Group", but when I move the tab to that group it just disappears rather than open the group. Any help would be appreciated! :)

Tried the PiP mode with YouTube and it didn't work for me. The video pop-up still appears even after un-checking the box in settings; once I click the X button on the pop-up, the video pauses, and will unpause only if I return to the original tab and press play. I've tried the following:

- Restarting my computer - Used keyboard shortcuts to close the pop-up - Blocked autoplay media on the YouTube website

Thanks in advance.

Hi,

I started to notice recently that calendars in some websites I browse with Mozilla are inaccurate. The dates like months, days,... are in a mess. Then I used Google Chrome instead of Mozilla and it went right. It was accurate with Chrome browsing those sites. Did you hear of the same problems with Mozilla ? What can be wrong ?

Thanks for your insights,

All the best,

Denis

Does anyone know how to remove the the keyboard shortcuts from Context Menus? For example: Ctrl+Shift+O beside Manage Bookmarks, or Ctrl+Shift+H by Show All History? I like having them gone so the menus can be narrower. This code worked until the latest update to FF 143: .menu-accel-container{display:none!important} thanks!

I'm having issues using Firefox with the Facebook site. Groups are slow to load and sometimes the chat and notification windows take forever to load with shimmering panels or a wait cursor displayed. I've cleared the cache and deleted the cookie, but that didn't rectify the issue. I don't have a problem with Edge.

Firefox crashed. I am trying to get it to how I had it before this. One of the problems is the new tabs thing. I know about CTRL-T, I have not used it. I have used the + on the tabs for years. I know, big deal, it's just inconvenient, interrupts my train of thought to switch, which is no big deal. But if anyone has a moment and can answer, it would be a blessing for me. Thank you.

Madam or Sir,

I do not know what happens but since a few days I cannot access any more https://mathworld.wolfram.com/ which is crucial for my work.

Since I am blind, could you please help me.

I thank you in advance

Best regards

Ubuntu - I use the SNAP version of Firefox - I generally have lots of tabs open but only use 5 or so of them and it's generally fine.... but when I am closing Firefox, it USES like 100% of the CPU and ALL of the RAM and ALL of the SWAP memory when closing.

This locks up the computer.

Sometimes it doesn't quite go all the way but I can watch it all happen in real time, using Task Manager - and that shows a solidwall of all resources occouring, when the close Firefox is run.

I am told by research via ChatGPT that this is a very real problem with the SNAP version and it's best to change to the Debian version, copy all the bookmarks etc., across and then uninstall the SNAP version.

It's rather disconcerting to have Linux crash because of this one app locking it up and frequently.

Chat GPT:

Is there a problem with Firefox Snap Version closing and using all the resources while doing so, which results in locking up the computer?

You're definitely not imagining it—there have been reports of Firefox's Snap version consuming excessive system resources (CPU, memory) and even causing lockups or hangs, particularly during closure. Here's what’s going on and how to mitigate it:

What’s Happening with Firefox Snap?

2. Browser Hangs or Locks the System on Close

On Linux (especially Ubuntu), users have reported that closing Firefox can lead to it hanging in memory, sometimes unresponsive and still consuming resources.
Super User
Ask Ubuntu
A stark example from Reddit illustrates the severity:
“About 50% of the time I open Firefox, it'll reach 100% CPU usage in about 30 seconds… PC completely unusable unless I shutdown.”
Reddit

3. Known Wayland Sway Bug

On Wayland/Sway setups, reloading Sway while Firefox is open can trigger intense logging, causing high CPU use and an enormous syslog.
Fix: Set MOZ_DISABLE_WAYLAND_PROXY=1, or upgrade to FF 125 where the issue is addressed.

Alternative Approach

Many users, particularly on Ubuntu, opt out of Snap completely in favor of the .deb package or PPA builds. These alternatives often avoid these specific issues. Ask Ubuntu Reddit

Thanks in advance.

Hello, I'm an avid user and supporter of Mozilla Firefox. But I installed AVAST as an additional protection tool...and I have just subscribed today to Avast Antitrack to avoid being tracked and hacked. But, to enable AntiTrack, I'm now prompted to add it to Firefox !? Before any action, I'd like to know that this will be efficient and safe : can you confirm that this is compatible with Firefox's proper operation? Thank you, P.Huens.

I can no longer sign in to sites that seem to use microsoft azure for authentication. Including: www.comed.com people's gas through https://login.wecenergygroup.com www.athletico.com which goes to https://myathleticob2cprd.b2clogin.com

All of them return a page that just says "Bad Request" after I enter my credentials and proceed.

I normally use AdBlockPlus and NoScript but I have both of those disabled.

I can login through chromium browsers.

Are others able to use those sites? Any suggestions?

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.
