On certain websites, I see that the background color of the new tab page replaces the default background color making the content unreadable, example:

If I browser this website: https://typespec.io/docs

Here's what I see (see the firsrt attached screenshot). Now, if I open the same URL in Private browsing, the background color changes too (see the second screeenshot). In the 3rd screenshot I'm adding the reference rendering, that's how I expect this website to render (Edge).

In the screenshot 1 and 2, the background color is exactly the same as the one used by the new tab page when I open a new tab.

Questions: 1) Why is that? 2) Can I change that?

Context: I'm trying to switch to Firefox (from Edge)

Firefox updated to version 131.0 64 bit. Bill payment functions on my banking web site stopped working. I cleared cache and cookies and restarted PC but didn't fix it. I tried using Microsoft Edge and the banking web site worked as always. The bank IT person said it was a Firefox problem. Also, the site says not to block 3rd party cookies, enable cookie tracking and cross-site tracking. In Firefox, I made all changes to allow these things for this site but it still doesn't work. Looks like the latest Firefox update is causing a problem that always worked in the past, while trying to fix something else.

I recently reloaded my M1 MacBook Air with macOS Sequoia. Ever since doing so, Firefox opens the right-click menu every time I press Control+Return (like when attempting to autocomplete a URL ending in .com, a feature I use quite frequently). It is only in Firefox that this happens, no other browser or program is doing this. I have uninstalled Firefox using AppCleaner, downloaded a new copy of Firefox 131.0 and reinstalled without any change in this behavior. Any ideas on what I can do to stop this so Control+Return only autocompletes a URL again?

A new version of the "List All Tabs" appeared on my toolbar today, shown on the left and hovered over in the attached screenshot (ignore the Malwarebytes extension icon). The old icon for this button was a chevron with approximately the same functionality. I was able to remove the old icon, but I'm unable to find a way to remove this one. Here is what I've tried so far:

  • Like the old one, the Customize Toolbar feature is unable to remove it since it is grayed out.
  • For a while, I was able to remove the old icon by going to about:config and setting browser.tabs.tabmanager.enabled to false. This solution does not work for the current and some recent versions of the button.
  • I attempted to create a userChrome.css file (following all the steps according to this this website) and added the following string: #alltabs-button { display: none !important; }

None of these attempted fixes have removed the button following a browser restart. Is there a way to remove it? I have no need of a button that shows me what tabs I have open when I can simply look at my toolbar.

There's one specific field I fill in very often and for some reason Firefox is really keen on suggesting me two searches that I looked up more than a couple months ago, on a totally different site. I can't even remove these suggestions or add new ones. When I used Vivaldi, it'd learn what I insert (even if it'd end up suggesting tens and tens of options), while Firefox doesn't learn at all.

For sake of an example, let's say that the word I use every day in this field is XYZ. Not even once was it suggested to me, I've only ever gotten the two in the screenshot below instead. And I can't remove them using the Delete key as some other article suggested.

Speaking of which, I just noticed the same thing happen to the subject line in this form 🙃

I'm visually impaired and had originally used a CSS code to fix this problem, but that was a couple of years ago. I just upgraded to 131.0.3 (64 bit) and evidently, that wiped out all my CSS changes. I tried to use the about:config code to change it, but it no longer works. I managed to increase the icon size a little by changing the density to normal, then back to compact. Even on normal, it was all too small.

I don't want to use another profile, because every time I do, I lose so much that it takes me hours to reinstall it all.

Is there an easier way to do this? I've tried a couple of things suggested online, but they were old settings suggestions, and they no longer work either.

ALSO, I now have to use F11 full screen to be able to perform anything on the toolbars. Before this update, I could just move my cursor up to bring the toolbars down, and use the back arrow or refresh easily. Now, the toolbars immediately go back up and I have to use F11 to do anything. How do I fix this?

TIA for any help you can give me.

You might have cookies blocked or cross-site tracking prevented. Depending on what browser you're using, check your settings for these terms:

Make sure cookies are not blocked and cross-site tracking is enabled. Follow any additional instructions in your browser once you have adjusted these settings."

Bank says it hasn't changed anything, and no tweaks I tried on privacy settings fixed it. I believe it's an issue with the new version. Can you tell me how to fix it or let me know when Firefox will fix it? The site works fine in Microsoft Edge, but I'd like to avoid using Edge.

I use Firefox on Ubuntu Linux, and it works fine.

For unrelated reasons I have created a new Linux Mint 22 boot partition, and I would like to use the same Firefox profile on both Linux OS-s, without having to move or copy the existing profile I use on Ubuntu. (The profile is placed on a third independent data partition!) I cannot find any information on how to do it. All information I find involves moving the profile, but then Firefox on Ubuntu would not be able to continue to use it.

I look forward to hear from you. Thank you. :-)

When I startup FireFox, it takes ~15 seconds to show me an page. After loading, it works normal and loads pages within a second, until I completely close the browser, and then the first page again takes ~15 seconds. I've been having this issue for the past few months.

- I tried disabling all my addons - Launched FireFox in troubleshoot mode - Deleted everything in DataReporting\Archived folder - Cleaned out History/Cookies and site data/Temporary cached files and pages - Tried both Default and Max protection for DNS over HTTPS - FireFox is allowed in Windows Defender firewall - Tried setting 'browser.cache.disk.enable' to FALSE - Tried changing 'Enable HTTPS-Only Mode in all windows' to 'Don’t enable HTTPS-Only Mode' - Windows and FireFox are up-to-date

None of the above saw any improvement in loading time.

How to change main domain is not automatically shown in the search of Firefox browser but the desired URL?

I have always typed "https://www.youtube.com/feed/you" in the URL bar both in firefox desktop and mobile and other Gecko-based browsers such as Zen, Floorp, Midori, Iceraven, Waterfox, Librewolf but dont know why it always shows up "https://www.youtube.com" as soon as I type "y".

I have not seen same behaviour in Chrome or Chromium-based browsers such as Edge, Opera, Vivaldi, as Chrome knows if I have visited "youtube domain" several times but not through "https://www.youtube.com/" but through "https://www.youtube.com/feed/you", then it shows me the latter, thus helps me in avoiding my few seconds of this bug or inconsistency.

Not limited to "https://www.youtube.com/" but to every other site such as Google.com or social media like Instagram, where I don't visit the homepage but my saved bookmarks page.

Can anybody clarify on this, if this is a bug or a gifted feature by Firefox devs?

And can we change this as this causes issues esp., for working people (I have recently shifted my Chrome data to a new Firefox profile so this is causing issues in working after MV3 drama) who visited direct URL not the one given or promoted or shown by browser. I dont like this and want to change it as it doesn't help me in anyways.

The most unfortunate thing is that we cannot cancel or reject or cut it out like Chrome does with "X" in the URL bar when it detects something which we dont know it to proceed with but Firefox, nah.

The biggest benefit is that it saves your time, helps you focus and avoid you waste your time, if the site has too many things to distract you from actual work. Like YouTube has great courses and podcast interviews and I have saved them and want to direct go there (https://www.youtube.com/feed/you), then I am saved from going to main page which has unwanted videos that will only take my time, losing my productivity. Is Firefox not concerned about our productivity, is Chrome only cares?

Do check 3 screenshots attached for better understanding, the 3rd one is from chrome.

My system memory is reading at 57% right now in task manager, that the vast majority of that is being used by Firefox.

Why?

Normally, this would be called a flaw in the program, not the user, as all I have done in regards to settings is "keep tabs previous open when re-opening Firefox" and "Do not automatically update" because Firefox took it upon itself to not re-open my previous tabs on the last update.

Why is this program eating up all of that memory? I have "Firefox (15)" in Task manager under "Apps" and then 13 more instances of Firefox in "Backround Processes"

Wtf?

There are 4 toolbars at the top of the Firefox screen. The default order from top to bottom seems to be:

I tried to use ChatGPT to accomplish this. After well over 6 iterations, I gave up (ChatGPT was still going strong - hallucinating?). The only code in userChrome.css that accomplished this is shown below. Unfortunately it leaves the order as:

I have reinstalled Firefox on my Mac many times, completely removed all files using app cleaner, and reset Firefox by holding shift and option on start. Despite this, the app is very slow to launch, and when it does no pages load or render. Opening a new tab freezes the entire app for 15-30 seconds, and when the tab opens it is completely blank. Attempting to browse to a URL does nothing, and the address bar just returns to being empty. Attempting to open settings does nothing, although parts of the app that open separate windows such as the about version info and bookmarks work fine. The only thing I haven't done at this point is completely reinstalling macOS, so maybe there is something wrong with my system config. I first noticed this issue when using the early macOS Sequoia betas, and assumed the app wasn't updated to support it yet. However after updating macOS and completely removing and reinstalling all traces of Firefox, it still doesn't work. I am currently using macOS 15.1 beta, however the issue also persisted on 15.0.
