I made a mistake and broke my FireFox profile. I made a new profile, then copied 11 files from a backup of my profile into my new profile folder, following these instructions https://support.mozilla.org/en-US/kb/recovering-important-data-from-an-old-profile

Most things came right back, that is very nice.

I am not certain if browser cache is disabled, which is necessary to avoid insanity while making changes to websites, which is what I do all the time. My mental defects did not prevent me finding thousands of web pages explaining how to complete this task. However, my mental defects prevented me finding any explanation created since the formation of the internet (I am estimating the internet first formed in 2008, because the dates of the answers I found indicated as such (anything before 2013 is basically the same as 2008 for internet purposes). And so, I am here to beg a moment of your time to help me resolve this risk to my mental health which will be extremely serious if caching does not discontinue its anti-social activities.

LEST YOU THINK I AM HELPLESS I found my way to about:config, entered cache into the search and up came about eighty various cache, assundry and other forms of affiliated/associated items. The list is diverse, but every item on the list has one very special thing in common with all the others, and as a group, they achieve an astonishing feat.

WHAT THESE configs HAVE IN COMMON All eighty configs produce by the procedures above have the letters c-a-c-h-e somewhere within them in that precise sequence, with no intervening or otherwise contrary letterizations.

THEIR COLLECTIVE FEAT They manage to organize themselves to perfection, including among them every single config containing the letters c-a-c-h-e in that exact order. No slackers calling in with covid or excuses of dogs eating their homework, all do their part in the roll call when its taken this way. This kind of character is exemplary and inspiring.

THE PROBLEM I attempted to calculate how many combinations of values these eighty configs can have. I got as far as determining a penny for each combination would amount to more than 400 times the gross product of economic activity since the dawn of recorded history.

STRATEGY Since trying every combination is too time consuming, my goal is to go straight to the correct config adjustment to send the cache away.

HYPOTHESIS Changing the last item on the list, marked 'cache' from TRUE to FALSE will produce the cacheless experience I must achieve in order to not impersonate a Molotov Cocktail.

The attached image shows what I have in mind. I am going ahead with experiements, but my hope is someone with knowledge will help click this thing in the way it should go.

Yesterday I got a new Mac, running macOS Big Sur (11.1). Previously I was using Mojave (10.14.6). Now on Firefox a lot of pages fail to load -- they show a blank page. Among them:

https://web.whatsapp.com/ https://open.spotify.com/ https://www.nytimes.com/puzzles/spelling-bee Citibank (after the login)

Some of these pages do open in a Private window. However, I already cleared all my cookies and cache contents, and I still cannot load thes pages in a normal window.

Can you suggest what I need to do? Thanks!

ADD: When trying to login at https://profile.theguardian.com/signin, at first I got an error message saying to "make sure that Javascript is enabled". But now it just goes through, except that the site doesn't know that I logged in. And again, in a private window I am able to log in.

It looks like I should just do all my work in a private window now, which seems strange

Hi! I'm using Firefox on my Mac. Last update. My problem is simple: when I close Firefox, it doesn't remember the last size of the window. So, for example, I normally use it on the full dimension of the screen (but not in full size: I'll post a picture to explain, because I'm not good with words hahah). Instead, when I relaunch it, it opens like in small size (I'll post a picture of that, too). Is there something that I can do? Thx.

I cannot get Firefox to stop using dark mode. I've tried uninstalling and reinstalling, checking my Mac's settings (dark mode is not enabled), and Firefox still shows dark mode in webpages (like Google News). It makes it really hard to read the page without reading glasses.

Is there a way to turn this off? It is really irritating.

When I have my computer plugged into an external monitor, I want new browser windows to open on the external monitor, but they always open on the computer's monitor. I have gone through the entire process at https://support.mozilla.org/en-US/kb/troubleshoot-and-diagnose-firefox-problems (clearing cache etc., trying safe mode, creating a new profile, refreshing Firefox, reinstalling Firefox) and the problem persists. This happens if I manually select "New Tab," "New Window," or "New Private Window" from the File menu with no existing windows open. It also happens if I use the key commands for any of these menu items. It happens if I use the menu bar on the computer's monitor or the menu bar on the external monitor. Opening a window and dragging it from the computer's monitor to the external monitor does not change anything. I've also tried using Divvy (https://mizage.com/divvy/) to move the browser window between windows with a key command, but after moving it this way nothing changes—new windows continue to open on the computer's monitor. How do I set which monitor Firefox will use for displaying new windows and/or get it to remember my preference?

System details:

MacBook Pro (15-inch, Late 2016) macOS Catalina, Version 10.15.2 Firefox 72.0.2 LG HDR 4K external monitor (Model 27UK850) CalDigit TS3 Plus Thunderbolt dock Computer connected to the dock with Thunderbolt 3 LG external monitor connected to the dock with DisplayPort 1.2

I've installed Firefox on my MacBook Air laptop, but every time I turn off my computer, the icon to access Firefox disappears from my shortcuts bar and I have to go back to my downloads folder, double click on the "Firefox 75.0.dmg" file and re-install Firefox. Meanwhile, all my bookmarks on Firefox are lost and have to start everything anew like a new customer each day. My membership email is the only thing that is retained therefore day-to-day. I've checked the settings and have even made Firefox my default browser but that hasn't helped. I should add that I also have Express VPN. When I add Firefox to the ExpressVPN's shortcuts, again it stays there only until I turn off the computer. Meanwhile, Google Chrome and my email icons remain on the VPN startup window and don't go away as does Firefox. Jacob

Hi! Netflix used to work great in Firefox on my Mac OS X 10.11.6 macbook. Now I've been getting an error message saying "Looks like your browser is no longer supported" when trying to play video on Netflix and it won't play. I noticed that it self-updated a couple times over the last few days but these updates did not solve the problem. I'm hoping that this problem can be fixed so that I can keep watching Netflix on Firefox, as I find Chrome and other browsers are very slow and laggy compared to Firefox. Thanks :)

It happens often: I am typing into a text input form on a website, and the pop-up (see attachment) appears for no apparent reason. In other words, I did not deliberately try to abandon my text entries, but for some reason the browser believes I have. Perhaps this is down to the overuse of shortcuts and touchpad "gestures" in my Macbook? I don't know why it happens, but it does. My question only concerns what happens AFTER the pop-up appears.

The pop-up has two buttons: "Stay on page", and the DEFAULT "Leave Page".

I have lost hours of work (text entry) because the DEFAULT is to "Leave Page". Again, this may be "physically" due to the twitchy Apple products I use, but it could be avoided if the DEFAULT were set to "Stay on page".

That is my first question: How do I change the DEFAULT to "Stay on page"?

I am told that this pop-up is the product of JavaScript running in my browser. That's all well and good, but it's not clear to me whose script this is.

My second question: What is the SOURCE of the JavaScript producing the pop-up; i.e. is this sourced by Mozilla, or is it sourced by the website creators?

Hi,

I use Firefox as my default browser.

Whenever I click on a link in an email it opens a new Firefox window instead of opening a new tab on a Firefox window that is already open.

My preference is for it to open a new tab on an already open Firefox window.

I have looked in the settings / preferences and can’t seem to find where to make this change.

Please can you advise the process / steps for me to make this to happen.

Hi. I've been using Firefox for Mac for ages and when clicking on a link, it would open the page in a new tab.

However, since the last update (84.0.2 (64-bit)) when I click on a link it opens it in the same tab.

I've checked options in "preferences" and can't find any option other than "open links in tabs instead of new windows".

I have also gone into "about:config" and checked the "browser.link.open_newwindow" which is correctly marked 3 (tabs).

I've disabled all add-ons but this did not solve the problem. :(

I'd appreciate any help ;) Thanks

My MacBook Pro is running OS 11.0.1 and using Firefox 83.0. My battery runs down faster than it used to. Apple suggested checking the Activity monitor and I noticed several instances of FirefoxCP Web Content. I have lots of tabs open. Most of them are using <1% of CPU, but one is about 50%. Is there any way to figure out what that is other than shutting down the tabs one at a time and watching the Activity Monitor?
