I am so tired of the stupid banner popping up every time I put something into full screen, that says "press escape to exit full screen".

Is there a way to disable that?

I am on a windows 10 PC.

After a re-start, my Firefox browser on a Dell laptop lost all history and has since also not been collecting websites visited. When opening a new tab, the shortcuts and recently visited websites are also gone and no longer being collected. My CCleaner recently updated itself to a new version but I unchecked the delete history for Firefox (which treacherously is clicked by default - I fell into that trap before). Happy to blame the new CCleaner but that would not explain why history is not being collected now - to me the fault seems to lie with Firefox instead. Another possibility that went through my mind: Is Microsoft sabotaging users of Windows 11 to force them to buy new? PS: Under "Privacy", "History", the setting is "Firefox will remember history", as it always has been and should be. But it has forgotten all previous history and it is no longer collecting any new history either!

If I have taken photos in past years on a particular date, I get an email from Microsoft to review them. I normally do it on my phone, but today tried it from my computer. The path is "One Drive" "Photos" "Moments" and then "On This Day." If you click on the photos that in the graphic that looks like a movie strip, a montage of the photos shows up and you can also click on one. However, in Firefox, I click on a picture and the screen goes gray, but nothing ever loads. I thought it was a Microsoft issue so used their help function. The rep and I tried it, then cleared the cache, then tried it in a private setting. We got the same result every time. Then he tried it whatever Microsoft's browser is called and it worked just fine. They said it was a problem on the Mozilla Firefox end, so I'm reporting it. Please let me know if you can help me make it work. I don't like using anything except Firefox.

I did some research recently on some travel sites.

Today, while trying to research which tab was doing DNS queries to SnapChat (which I never use) I learned about `about:processes`. I found 5 "hidden" tabs from various travel sites (some of which I never visited) running in the background. I did not explicitly hide any tabs.

WHY IS IT ALLOWED FOR SITES TO KEEP OPEN HIDDEN TABS AT ALL WITHOUT TELLING ME ABOUT IT?

This is not conducive to trusting Mozilla.

I GOT TIRED OF FREQUENT FIREFOX CRASHES (C0000005) IN BOTH THE 64-BIT AND 32-BIT DESKTOP VERSIONS. I HAVE BEEN USING THE 64-BIT VERSION IN WINDOWS 11 (I HAVE A HIGH-END SAGER LAPTOP WITH 32GB RAM. I INSTALLED THE FREQUENT FIREFOX UPDATES BUT THE PROBLEN PERSISTED EVER SINCE VERSIONS 42X WERE RELEASED. I TRIED THE 32-BIT VERSION BUT THE PROBLEM PERSISTED. FINALLED, I TRIED THE DEVELOPER VERSION: NO MORE CRASHES! I READ THE RESPONSES FROM YOUR CLUELESS STAFF TO OTHER CUSTOMERS WITH THE SAME TROUBLE. THIS IS NOT A WINDOWS ERROR; THIS IS A FIREFOX APPLICATION ERROR. MAYBE SOME OF YOUR FIREFOX DEVELOPER CODERS SHOULD ASSIST THE 32-BIT AND 64-BIT DEVELOPERS. OR, DUMP THE VERSION 4X CODE AND BUILD ON THE MORE STABLE 39X CODE. ALSO, DON'T BLAME WINDOWS FOR FIREFOX APPLICATION ERRORS. AND...NEVER SUGGEST A WINDOWS REINSTALL FOR FIREFOX ERRORS!!!

I was asked to create a new profile in order to keep using Firefox, despite never having an account. After I clicked okay, it opened the new version of Firefox, but without all the passwords, bookmarks and history of the past few years. This is really inconvenient. I have since then made an account, but the fact that I can't find any of this data anywhere has me worried that every time I update Firefox it will wipe my account.

mozilla won't save my previous windows and tabs even though i have that check marked in the settings. it's been like this for months. to keep them i've had to keep my pc on for moths. help, i'm thinking of leaving Mozilla because of this, it's incredibly frustrating to lose all my work every time.

Firefox kept eating my RAM, running dozens of processes. I have gone into about:config and set the dom.ipc.processCount to 1 - then I restarted Firefox and found 5 processes running straightaway before even using the browser. I closed it down and have started it again and now there are 11 processes running with just one tab open. Firefox(9044) Utility(7552) JavaScript oracle Network (15912) Data Decoder (11364) GPU (18744) About pages (12536) Preloaded new tab Extensions (20544) Preallocated (16132) Preallocated (13780) Preallocated (16044)

The problem repeats on three different computers which are not infected with malware. One computer with slightly less RAM I now cant even use Firefox at all (though all other browsers work fine) because the tabs constantly crash due to the high number of processes. Is there any way to set the process limit low in a way that Firefox actually responds to?

Good evening,

When the translator starts translating from English to French, it displays Indonesian, but I haven't installed anything in Indonesian, and I don't read Indonesian, so where is it coming from?

I'm hacked ?

Since this week's update of Firefox Developer edition when the browser is restarted tabs do not load until I reset the browser.

I suspect an add-on but have not been able to determine which one.

This is happening on multiple (3) physical computers.

I just started a new work role and haven't been able to find the time to troubleshooting of the issue myself.

This has been very disrupting and stressful.

Every couple of days I am unable to access my email accounts, facebook and most web pages.

The only way I can access them is to refresh Firefox after which all work OK.

Really like firefox but am getting fed up of having to refresh it constantly any advise you could give would be very much appreciated.

Hello: Thanks for creating Firefox. This is my first question after more than a decade using it. I couldn't find proper information about this. This week Firefox started to show a tiny shopping cart icon over the task bar icon of Firefox (image attached). I don´t know what it's and I can't find the functionality that make that appear. So, How do I disable it? I use Firefox everywhere, and I don't like it, specially in my job's laptop as my boss can occasionally see it and it's obviously not work-related in my case. I use chatgpt to get answers and it points to a "Shopping Assistant" feature, but I don't find it. Is it related? The term is so common that I couldn't narrow down to my specific question (what is it and how to disable it)

I use windows 11 and 138.0.4 (64-bit)

Thanks in advance for help

Yahoo Finance stock charts are not loading. Never encountered this problem before this week. A GeekSquad tech support person was not able to fix the problem and recommended I contact Firefox. Edge and Chrome load Yahoo Finance stock quote sites just fine; I'm only having trouble with Firefox. Any ideas on how to fix? Thanks! Carol

Hello,

I’m experiencing an issue where I cannot use ChatGPT-5 in Firefox. When I log in and try to select or use GPT-5, nothing loads or functions properly. Other models like GPT-3.5 work normally, but GPT-5 does not respond.

I’ve already tried refreshing the page, clearing cache and cookies, and even disabling extensions — but the problem persists. Could this be a compatibility issue with Firefox? Any advice or support would be appreciated.

Thank you in advance for your help!

My primary PC died about a month ago, and the SSD is fried. I had it synced to both my phone and a secondary one, so no problem accessing things. I bought a new one online, and it just arrived. Then, when I tried opening all my tabs on my new PC, I found that they were no longer available, on either that one, or my other devices. This is new, because I had already recovered a few individual tabs to my phone previously, but I hadn't thought to open all 50-100 of them then since I was waiting on a new primary laptop. The device still shows up among the connected services on my account, but it doesn't show the tabs anywhere I could find, and since the SSD doesn't work I can't go into the files and manually port them over. Is there a way to solve this?

I can NO longer log into my BANK, I changed the security settings back to "standard" but I STILL CANNOT LOG INTO MY BANK. it's website acts as though I'm a new customer & want's me to open an account,I ALREADY HAVE AN ACCOUNT & HAVE HAD AN ACCOUNT AT THAT BANK FOR MANY YEARS! I have jumped through many "loops" at the bank trying to fix this mess, but they can't,FIREFOX IS NOW THE PROBLEM & someone needs to find out what they changed in their updates that has prevented me from logging into my BANK.

When I click a link I always want it to open in a new tab. How do I do this without doing a right-click and selecting "Open in new tab"?

I want it to open in a new tab when I simply click the left mouse button.
