I'm using macos 12.5

Firefox will not open any windows.

When I try to open Firefox by clicking on the dock icon, nothing happens.

If I right-click the dock icon and select 'Show All Windows", a message takes over my screen. The message says "No Available Windows".

I manually deleted the caching directory in my homedir.

I then deleted Firefox, downloaded the latest version and installed it.

Attempting to open it fails again. The same symptom recurs.

I'm running the latest version - I downloaded it about 20 minutes ago. But I can't find the version number because the application won't actually open.

Firefox won't stay downloaded to my computer. I am having to download it multiple times, especially if my computer has updates.

On a separate note, when it does actually stay on my computer over night, it never keeps me signed in to my Firefox account. I have to log in to it daily to have my bookmarks and passwords.

Also, it never remembers the theme I have picked for it. I would love some advice on how to fix this.

I've read through a ton of articles, and I can't seem to find a fix.

Cannot display my history in my sidebar. Receive this message:

XML Parsing Error: no root element found Location: chrome://browser/content/places/bookmarksSidebar.xhtml Line Number 1, Column 1:

Cannot find a way to fix.

My Firefox version is 86.0 on Mac. OS Version is 11.2.2 Big Sur.

I found that basically all color rendered in Firefox is more vibrant than Safari and Chrome, maybe Firefox doesn't handles color management right and renders sRGB in full P3 color space, lead to a over saturate color for almost every element on webpage.

Hopes firefox can fix this soon, I love the efficiency and privacy features on Firefox, This is the only bit I found a little uncomfortable.

You can test your browser here: https://cameratico.com/tools/web-browser-color-management-test/ if you have a P3 support Mac or Windows.

I'm using Firefox 86.0 on an Apple Silicon Mac mini (16 GB/2TB) with macOS 11.2. Several times a day when I return to the browser, it will have become completely unresponsive to clicks and or typing. In this state, I can't click on web pages, or controls in the tab bar. However, the app is not beach-balling. I can quit by right clicking on the dock icon and choosing quit from the menu (I don't have to force quit). Relaunching fixes things. Also, if I have, for example, clicked on the "new tab" button in the tab bar, once I've quit and launched again, the new tab will be in the window, indicating that the command was processed, but the result was not visible. Sometimes, but not always, when in this state the page display looks like it has been scaled to about 50%. (As if I'd hit "Zoom out" five times). One clue that may relate to this is, I'm running in scaled mode on the monitor (The monitor is capable of 3840x2160, but I'm scaling things in the Display control panel to 2560x1440.) Apps are running in Retina mode. I have tried running Firefox in Safe mode, but that didn't help. I have a lot of tabs that I don't want to lose, so running in a fresh user profile is kind of difficult, unless there's a simple way to transfer open tabs between profiles.

Hi! Even if i'm an old user of Firefox, i'm new to this support/forum thing, so I apologise if i'm in the wrong place. Today, after watching some videos on a specific youtube channel, i noticed that the channel appeard on the "highlights" section in the home page of Firefox. Nothing strange in that, but i noticed that the thumbnail of the user of that youtube channel was in high definition in the "highlights", even if when I viewed the page information of YouTube, on the media tab, I wasn't able to find an image with such an hight resolution. I would be clear: I'm not talking about the YouTube red logo, but on the user's channel image (rounded, near the name). The "moz-page-thumb://thumbnails/?url........" have a resolution of 448px x 448px. The image on youtube have the maximum resolution of 176px x 176px. So... Where have Firefox finded that image?? Is there involved some kind of upscaling?? I really appreciate the hard work of Mozilla, and I hope that will go on on this way.

So my account is synced and everything, but if I quit my Mozilla browser on my Mac everything gets deleted. Passwords, bookmarks, everything. It's so frustrating that I may go back to Safari because this is ridiculous.

After logging in with my firefox account on another firefox browser all my bookmarks haven't sync. is there something that needs to be done in order to pull the bookmarks from my account? i don't have any access to the old computer anymore

Hi there,

I refreshed Firefox because I found it was running slow, and now my saved logins and passwords are not in my settings anymore.

They are still on my phone but they won't sync now to my iMac desktop.

Is there a way to restore them or resync!

Thanks for your help.

The option in the Help menu for "submit feedback" is still present on version 87 but is no longer functional and has been out of service for 3 months.

Is an expected date or version pending to reactivate or will it be removed?

Firefox is saving multiple OLD passwords, I just want it to save one: the current password.

Is this possible? Help function in Firefox is freaking horrible

I have a Mac and every time I quit Firefox, when I reopen the program all of my bookmarks and passwords are gone and I have to re-login to my Firefox account every time I open the program. Once I re-login all my passwords and bookmarks come back, but I don't want to login to Firefox every time I open the program. Is there anyway I can get it to stay logged in even after I've quit Firefox?

I have been experiencing this weird problem since I updated my Mac from Catalina to Big Sur. On full screen mode, the menu bar is normally hidden and whenever I hover the mouse pointer at the top, the menu bar automatically becomes visible. Sometimes, without any pattern, the menu bar stays there even I hover the mouse pointer the bottom or somewhere. To solve this, I always need to quit and full screen mode. As far as I know, this happens only in Firefox. Is there anyone having such an issue (and a solution for this)?

I have the same problem. It's really very annoying. Any suggestions?

How do I stop Firefox from signing me out of social media and similar sites so that i have to sign in every morning. For years, My sign in to Instagram, Facebook, Twitter and LInkedIn in particular have not required daily signing in. It is a pain to have to it every day.

HI I am a trainer and web developper and in all trainings and as a designer I am using the Firefox Inspector. This morning, suddenly the menu under EXTRAS is not showing anymore the "INSPECTOR". Don't know what has changed! I installed Firefox again, no change! I know, that I can still activate the inspector via OPTION COMMAND C but this is not very intuitive for my trainings! See screenshot: What happened? Any ideas?

Thank you in advance! Mathias Will

Firefox version 87.0 (64-bit) on M1-based mac using macOS 11.2.3.

I was happily using name and address form fill for filling out online petitions and so on earlier today, and the form fill just stopped working. I've never seen this happen before, this has always worked in every browser I've used including Firefox, Edge, Chrome, Brave, Safari, and all the other browsers I've tried or used for some period of time. No other changes in behavior, just name and address form fill stopped working.

I did try dumping my user profile and starting Firefox with a new profile. While it was time-consuming to get my configuration all back to where I was, I found the same problem with name and address form filling, not working. I haven't added any extensions lately, or done anything else that would affect this that I'm aware of.

Any idea how to troubleshoot this one?

Hi everyone,

I'd like my new tab page to be a local html file (that uses .js scripts and local image files so I cannot use this add-on or that one).

A few versions of Firefox ago, the method described [https://support.mozilla.org/en-US/que.../1251199|here] worked perfectly fine but it's not the case any more.

I'm using MacOS version 11.2.2 and the latest version of Firefox (87.0 64 bits).

Thanks in advance to anyone who will be able to provide help! Best, Léo
