Firefox Support Forum

Please see the attached screenshot. I get this popup EVERY TIME I open FireFox. I've tried a number of different suggested "fixes" from Google Searches with no success.

I want this popup GONE.

I am having the same issues as the person in this thread, but unlike their situation, firefox has not fixed itself out of nowhere. https://support.mozilla.org/en-US/questions/1104044

Everything in the firefox browser looks like it was stretched it out in MSPaint, while my actual OS interface and every other app/software UI looks fine. I have tried simply restarting my computer, as well as every solution in the linked thread, as well as refreshing firefox, and uninstalling/reinstalling, which only served to mess up my shortcuts on the home page. To be clear:

• Hardware acceleration is turned OFF, as suggested in any thread I've found where a resolution issue is addressed.
• setting layout.css.devPixelsPerPx to 1.25 specifically makes it almost legible. Almost. It's still incredibly grainy. Any higher even a small portion of a webpage takes up a ridiculous portion of my screen, rendering it just as unusable.
• In messing around in config, I found that setting gfx.color_management.rendering_intent to 5 helped, in so far as it sharpened things up a little, but it did not FIX the issue. Any value above 5 seems to have zero effect or change.
• Absolutely EVERYTHING else except firefox looks absolutely fine. It is ONLY firefox that is having this issue of all the applications/interfaces on my computer.
• Everything in firefox is affected- images, text, the tabs and address bar, bookmarks bar, absolutely everything.

This is a problem I've had for a while and thought it would be eventually fixed, but no luck so far.

TL;DR - Almost every time I add or remove monitors my Firefox hangs.

More context: I use a PC laptop and constantly switch from using just the laptop screen to using just a set of two monitors, with the laptop closed. What I do is, I lock my machine, with Firefox open on the laptop screen, connect the monitors, close the laptop lid, and unlock the machine. That causes Firefox to hang and I'm forced to kill it and open it back again. It usually reopens all tabs without a problem but the issue is pretty annoying.

My current version is 125.0.2 and I'm sure the problem dates from several versions

After Firefox updates itself, the restarted browser session is unresponsive to mouse clicks - can't follow links, can't respond to UI dialog boxes, the browser is unusable for practical purposes. It's fixed after another manual restart. This unfortunately breaks all the streamlining Firefox has done to restore the session after an update, because none of that stuff works the same after a manual quit and restart. This is happening on MacOS, and it happens across multiple computers.

After the latest update to 125.0.2 (64-bit) the browser works fine for a few minutes and then pages won't load. It starts working again after a restart [ for a few minutes]. I have cleared the cache & data. Chrome works ok.

I find it very difficult using Awsome screenshot, in fact I never use it, but used to use it, when it was on my tool bar, can I get it back there.

I cannot drag it from "customise tool bar" as it does not show there, it shows in my list of add ons, I have tried removing it, then reinstalling it.

Ever since the latest update, the picture-in-picture function stopped working properly. If I activate it, the video will automatically go to full screen, and I need to press the full screen button multiple times to move it down to a small box. I am using Firefox on a Mac laptop.

Hey all, as of the past few days when I get the prompt to enter my password on Outlook.com (And microsoft.com) and hit 'sign in' the page just reloads and nothing happens. There is no failed login message, the page just reloads like I didn't hit sign in. I have disabled all of my extensions, cleared cookies and cache, ETP... with no luck.

Works fine on Chrome for android...

I'd really like to stay with Firefox so all help seriously appreciated

hi guys, i want to change my default favicons but i cant find this path on my mac.

.bookmark-item {

 list-style-image: url("chrome://global/skin/icons/defaultFavicon.svg");

My Firefox can only be shut down by TaskManager, or by clicking on the three horizontal bars and then dropping to exit.

So I can't close any single tab 'without closing them all', that's the real annoyance. I also can't close any individual windows I opened instead of a new tab, without closing all tabs and windows. Finally the classic windows ALT+F4 closure that's built into Windows doesn't close Firefox, and if it did I suspect ALT+F4 would close them all. Bottom line Firefox is seriously close-resistant.

What precipitated this was I allowed a previous Firefox update to download-install, and it tanked my performance, I figured your team would fix that issue, but in the meantime what I did was uninstall that version and reinstall the version I had been running before that update. Tilt! That action resulted in the close windows or tabs problem.

Summary: I am using the latest version now, but with it came this "can't close any individual tab without closing them all, and can only close even then except by Taskmanager or by clicking the 3 horizontal bars then dropping to Exit which also closes all Firefox tabs and Windows. This problem has surfaced before in this support, and none of the solutions worked, probably because I got to this place uniquely. I did read before submitting this.

Hello everyone,

since my last update (125.0.2 (64-bit)), an additional website always opens when I open a website in Firefox. This is called "Page load error" in the tab; the content of the page is as follows:

Error: Connection failed

An error occurred while connecting to 0.0.0.1.

   The website may be temporarily unavailable, please try again later.
   If you are also unable to access another website, please check the network/Internet connection.
   If your computer or network is protected by a firewall or proxy, please make sure that Firefox is allowed to access the Internet.

How can I prevent this additional page from opening?

Thank you in advance for your help!

Whenever i sign into youtube and then close the window when i come back ive been signed out and have to sign in again. i have "delete cookies and site data when firefox is closed" off and dont know what else to do

Hello everyone, a long time ago i changed my youtube name to something else and to this day it never updated on firefox. Yesterday i finally asked youtube support about it and they told me to check with mobile or other browsers and there it works fine, so only firefox is borking out on that one. Do you have an idea how i can solve that?

sincerly, Cammy

I have attached images of what slowly occurs when I don't clear my cookies, websites start to slowly and slowly load less and less until they eventually completely break and wont load and I have to clear my cookies, resign into everything. and rinse and repeat every few days or a week, I also attached an image of what the purchase screen is supposed to look like. Looking at this via Microsoft edge

Dear Sir or Madam,

I have been having problems with Firefox on my Desktop-PC for about a week now: I am almost always shown another tab with an error message (an new tab with allways the same content) in addition to the website that is regularly called up and also works:

Tab-Headline: Seiten-Ladefehler Fehler: Verbindung fehlgeschlagen

Beim Verbinden mit 0.0.0.1 trat ein Fehler auf.

   Die Website könnte vorübergehend nicht erreichbar sein, versuchen Sie es bitte später nochmals.
   Wenn Sie auch keine andere Website aufrufen können, überprüfen Sie bitte die Netzwerk-/Internetverbindung.
   Wenn Ihr Computer oder Netzwerk von einer Firewall oder einem Proxy geschützt wird, stellen Sie bitte sicher, dass Firefox auf das Internet zugreifen darf.

It doesn't matter which regular website I call up - it also happens when I call up the Mozilla Firefox page.

It is as if my website call is executed twice: once normally and everything is displayed correctly. And once as an extra tab with an alleged page loading error where the connection has failed.

How can I prevent these additional tabs with the error message from constantly popping up and being displayed? I have not made any other settings and Firefox has always worked perfectly so far. It doesn't happen with Google Chrome, for example - so it's not my PC.

Can you help me?

Kind regards Daniela Bohle

I use the Rapport Add-on to protect my personal info especially when doing on-line banking at the moment I have to use Chrome but I would rather stay with Firefox but you dont have this extension why?

Firefox is not permitting videos from YouTube that other browsers easily play. This needs to be fixed. YouTube offers their Premium subscribers videos which can be played at a higher bitrate, which means even 1080p can play at a higher quality. When setting quality on a video, in addition to the 1080p, you can choose "1080p Advanced bitrate" as an option. Firefox has trouble playing these files, whereas Safari and other browsers don't have a problem with YouTube. Please fix this.
