• Bulleted list itemI understand! You're asking how to use Mozilla Firefox or Safari. Here are some basic steps to get you started:

Mozilla Firefox:

1. Download and install Firefox from the official website. 2. Open Firefox and set your default search engine and homepage. 3. Use the address bar to enter URLs or search queries. 4. Explore the toolbar for bookmarks, history, and extensions. 5. Customize Firefox with themes, add-ons, and settings.

Safari:

1. Open Safari on your Apple device (it comes pre-installed). 2. Use the address bar to enter URLs or search queries. 3. Explore the toolbar for bookmarks, history, and sharing options. 4. Customize Safari with extensions, settings, and privacy features. 5. Use iCloud to sync bookmarks and history across devices.

Hello,

I am trying to force two or three websites to detect my timezone as UTC, even though my local system time is not UTC. I figured out how to do this with ALL sites by setting privacy.fingerprintingProtection to "true" and entering "+JSDateTimeUTC" in privacy.fingerprintingProtection.overrides in about:config.

Now according to docs, privacy.fingerprintingProtection.granularOverrides "can be used to add or remove features on a domain granular level if privacy.fingerprintingProtection is enabled," but I can't figure out how to get it working.

Any input is appreciated.

I keep getting notifications asking me to update firefox every couple of days. I download the update, it goes smoothly, the notification disappears, but it comes back in a day or two. I also have my setting to supposedly do updates automatically, but that doesn't seem to be working. Please help!

When trying to install any extensions on either the Mozilla Addons website or directly via the Extension settings, it fails to do so.

I've attached a screenshot of the Mozilla Addons website when it fails to install the extension. On some other addons that I've attempted in the past, it just shows the throbber forever.

I have checked the Multiprocess Browser Console and it says that it fails to move the file because it's locked (NS_ERROR_FILE_IS_LOCKED). I have also attached a screenshot of that.

Concurrent with updating to Firefox 126.0, when typing into the address bar, the list of suggested sites covers-up the address bar. In fact, the top of the list is off the screen. I don't see any other posts relative to this, am I the only one with this problem... and how do I fix it?

Hi All,

For some reason my tab icons look a little low, and I would like them more vertically centered.

I've been trying to move these icons around using some older code that doesn't seem to work anymore.

The code below no longer has any effect.

Does anyone know how to move the tab icons up 1 pixel?

Thanks!

/* padding doesn't move them */
.tab-throbber, .tab-icon-image { padding-bottom: 4px !important; }

/* margin doesn't move them */
.tab-throbber, .tab-icon-image { margin-bottom: -2px !important; }

/* can't even turn the icons off LOL */
.tab-icon-image { display:none !important; }

For some reason, recent updates caused my Firefox address bar to misbehave.

I have already murdered the unwanted search engine suggestions which the standard settings failed to kill - I just kept turning things off in about:settings until the garbage feature died.

However, I am still unable to address the most annoying bug.

When I start typing in address bar, the pop-up box with suggestions, rather than attach itself to the bottom of the address bar, goes to some imagined, predefined anchor point which is off screen, somewhere outside the confines of the window. As a result, I see some suggestions, but I no longer see what the hell I'm even typing. I am attaching a screenshot. This is super annoying, as I am literally forced to either use bookmarks, or type out urls in notepad then paste them over.

Anyone can help?

About tab crashes Every time I open Firefox, it crashes immediately and does not trigger the crash report window. Even though I have checked and enabled the option to send crash reports in the settings, it doesn't work. When I look for crash report logs, it shows that I have not sent any crash reports.I've tried many methods to view the crash report, but it just shows that there are none. I only found this information related to crash reports in the installation files.(you can see it in the picture)，hope someone can answer this question, thank you very much.😭

When visiting the "support.mozilla.org site, third-party translantion add-ons(such as "Immersive Translate") can't work. It says "can not read or change data on this site". I want to translate it on the same page rather than skipping into a new page. However, it can work on the "www.mozilla.org" site. When visiting on Chrome, there is not a problem. Is that site just privileged on Firefox ?

The story is when I accidentally clicked on a sick video, YouTube start to recommend me similar sick videos.

So my question is how does YouTube get my identity?

I'm not logged in. my profile is actually a snapshot, so when I restart Firefox, it go back to the snapshot. I even restarted my ISP router to get a new IP address. This did not work.

Only when I create a new profile with "firefox -P" does YouTube start to see me as a new person.

So how does YouTube identify my Firefox profile? I don't think it's in the https request headers. Weird.

I simply want to use a password to open Firefox. I don't want to set up Firefox sync. How can I set up a simple password as permission to open Firefox without accessing sync?

I am trying to connect to a website but I keep getting error code 522. I've tried using Chrome and it connects to the website with no problem. I've checked my privacy settings and I do not have that website blocked. What else can I check?

What's the best way to set up Startpage private search in Firefox? Should I manually change the settings or install the extension? Also, it seems like Firefox could improve the process for us.

I have an iMac with Sonoma 14.3.1 with Firefox 115.9.1 esr . It is for personal use, not for a business. I just learned that there is another Firefox version (124.0.2) which is not esr....

Which version should I use and why?

If I should use the "normal" version, how do I replace the esr version with the "normal" one ?

Thanks.

Hi so am using version 125.0.1 and on my windows 10 machine I can add custom Search Shortcuts (the Add button is present) but on my windows 11 machine, the same settings page the Add button is dissapeared... Is it a limitation for Windows 11 machines?

Recent issue, April 2024. Had version 124 Firefox on Win10 computer and went to Help - > About to have Firefox check for updates. This has worked just fine up until now. The message "Failed to check for updates." is shown in the About screen. I have uninstalled and re-installed Firefox with the same results. Have also un-installed Firefox, un-installed Mozilla Maintenance, then removed Firefox data from App Data folder in user directory, then re-installed with the same results. Also, now when I access a local media server, I keep getting the message "Firefox is installing components needed" and that never goes away. Any ideas?

I am having a very frustrating problem that is driving me huts.

Just the other day I was commenting in a text box like this one and I hit caps lock on my keyboard and a little grey box I had never seen before appeared with a locked lock. Then when I hit caps locks again on my keyboard an unlocked locked appeared in the little grey box. But it stays in cap locks and no matter what I do it won't go back to lower case. And when I say nothing shuts it off I mean its doing that on every site I try to comment on. Shutting down the browser does not help. And the only way I can get caps lock off is to actually shut down my whole computer and basically start all over.

You community volunteers are the best and quickest help I can get so I went straight to you for help.

When I try to customize the toolbar in Firefox 115.10, the browser tries to change the page to the customize toolbar / overflow toolbar page. However the page flashes on and then reverts to the normal browser page. The page showing customize toolbar/ overflow toolbar, is transient and does not last. So I can't even customize the order of the buttons on my toolbar. This wasn't a problem a few days ago before the switch to this latest version. In particular I am trying to change the position of the "home" button to the left side of the address box. I just can't bring up the customize toolbar page. I'm not talking about the position of the add-on or extension buttons...just the home button. Hope this is clear. By the way, I've even tried this in safe mode to no avail.

Device: Surface Pro X SQ2 OS: Windows 11 Home for ARM (Up-to-date at time of writing) Firefox Version: 125.0.3 (AArch64 up-to-date at time of writing)

I am having an issue with Firefox and video playback, specifically on YouTube. When I play a video in default view mode, the playback is super choppy / low frame rate. When I change to theatre view or full screen, playback works perfectly.

I've tried incognito windows and troubleshooting mode with no improvement.

Microsoft Edge works fine.

Not sure where to go from here.
