Firefox Support Forum

This problem appears on MacOS 10.13.3 but NOT Linux Mint 19.3 (Tricia).

Repeat-by:

1. Start here:

       https://www.cnn.com/

That page should load cleanly.

2. Now click on "Live Updates", which is the top entry in the middle column of that page, and as of 3 April 2022 11:20 AM EDT takes you to:

       https://www.cnn.com/europe/live-news/ukraine-russia-putin-news-04-3-22/index.html

On MacOS, that page loads and is momentarily visible; then the page/tab it's loaded in goes blank. On Linux, that page loads as expected and remains visible.

Notes:

The problem did not happen with Firefox 88.0.1/MacOS.

The problem does not happen with Firefox 98.0.2/Linux, i.e., it appears to be specific to MacOS.

The problem remains whether extensions are enable or disabled (one a time or all at once).

The problem remains after the cache has been flushed and pages have been reloaded.

The problem remains after Firefox has been (completely) shut down and (cleanly) restarted.

The problem does not happen with Chrome/Chromium on either MacOS or Linux.

The problem also happens on *some* other pages on CNN's site (but not all) and on *some* (but not all) pages of other sites but there doesn't seem to be a pattern that explains which URLs exhibit it and which don't. This suggests that it's not privacy settings or extensions or anything like that, because there's no reason for those to vary from page to page within any one site.

If I'm VERY fast on hitting the "X" that stops a page loading/rendering while in progress, and I get the timing just right, I can catch it before the page/tab goes blank. So it appears that Firefox is in fact fetching all the content and can render it, but then for some reason is blanking the page/tab once that's done.

The attached screenshot shows what the problematic page (from step 2 above) looks like on Linux. On MacOS it's blank, so I didn't include a screenshot of that.

Can Mozilla please update and fix the bugs? After downloading new update i am unable to hear sound from my internal speaker on my macbook air.

My final exams are around the corner, and I am desperately looking for Mozilla team to respond. I have launched a complaint earlier but no action has been taken. Please fix this issue.

I just upgraded to Firefox 99.0.1 on my Macbook Pro. Since then, nothing but trouble. Nothing will sync, none of my passwords are saving. I turned on sync, it says it is turned on, yet I have to manually enter my passwords every time. It is incredibly frustrating.

When I attempt to print a deposit slip or send an invoice from QuickBooks Online, the embedded pdf only shows if I set the pdf extension to always display in firefox. If I set it to always ask, I then pick show in firefox and it opens a new tab with the pdf. AND it downloads it to my download folder, neither of which I want to happen.

Running Firefox on MacBook Pro iOS v 12.2.1. Recently updated Firefox, now while navigating through tabs, FF randomly selects multiple tabs. When this happens, I can only view the one tab, all others are selected, but I cannot then go to that tab to view. I'm not sure I'm explaining this well. Also, I cannot close the tabs with the X but must right click for drop-down menu to close. I can open new tabs, but that tab is becomes the anchoring selected tab, any other tab I try to go to then becomes selected, as well as every tab in between, none of which I can actually view, they are stuck. I have tried "select all" in hopes of then de-selecting, but deselecting is not an option.

This is really holding me up as I have work to do and cannot view the necessary tab. I'm extremely frustrated.

LOL, as randomly as it starts, it stops...I wanted to take a screen shot, but no, everything is fine now.

Hi Support,

I tried to upgrade Firefox on my Mac. The file could not complete because it said it was either corrupted or incomplete. I then re-downloaded another Firefox update, but can't find my browser history.

Please help!! Thank you!

edit bump: /moved thread from Firefox for iOS (iPhone/iPad) to (desktop) Firefox section since you have macOS.

Setting the clock! I moved permanently from New York to Hawaii. I have been unable to find a way to reset the clock in my MACmini to show correct time in Hawaii. It still thinks I live in New York!

How do i get rid of the searchitnow scam fake hack on Firefox?

All the many links online to info on how to fix it is the same and none of it works. So it must all be part of the scam. Fucking horseshit. Can I say that?

Can someone tell me how to get rid of it in an actual human non fake way?

I get redirected to yahoo so I thought I could just check the add-ons to look for malware. No add-on showed up in Firefox. I guess I have to find the file somewhere in my Finder but I found nothing in LaunchDaemons, Application Help or any other folders where it might be located. Some people on the internet said that you should look in prefs in Firefox but there is not anything suspicious. How can I delete the redirect virus?

On a trusted website, for a class which I paid a lot of money to attend, I get this error message, on FireFox only: The media could not be loaded, format is not supported.

I used to LOVE Firefox,but I'm getting frigg'n irritated by it right now. Chrome and Safari both open this page. I had this same problem a few days ago, was sent a long list of possible ways to deal with it that were all over my head complicated. I chose the simplest one- to clear caches, and it worked! yay, for a couple of days, now the error is back. I there must be a different solution , or cause, than the cache one - What needs to be turned on or off, so this doesn't happen? Too complicated, too frustrating.

I'd love it if someone could give me some more ideas on this. Macbook Pro 16" 2021, IOS Monterey 12.1

Thank you!

recent iOS update to Catalina 10.15.7 resulted in deleting Firefox entirely. Just reloaded Firefox browser (which I prefer to Safari) but none of my bookmarks survived. Can I restore them from some record of them within Firefox? or do I just have to recreate them all?

Simple. I want to change the background color from black to white. I hate the black background.

It will make me leave firefox and use a different browser.  Don't understand why this is not easily found in preferences.

Get back to me fast please.

I discovered a little shield next to the URL, and read up on how sometimes the tracker blocker makes sites no longer work, I imagine you are getting a lot of calls like this? So I turned it off, did a refresh, no change, did a restart, no change, turned the computer, Macbook Pro OS Monterey 12.1, off for 20 minutes. no change. I'm furious, and having a hard time dealing with this.

The error message says: ''''The media could not be loaded, either because the server or network failed or because the format is not supported.'''' Except it's worked fine for a week now. Until this morning. Any more ideas how I can get this to work? I realize you all are volunteers, but jeepers, there must be a way to get help sooner than maybe look back occasionally see if a volunteer has seen this. I'll try a different browser.

I was told to open Firefox Account Settings, and then "Privacy Settings" and then to dropdown "Custom Experience". I use a MAC, and I cannot find there things, is that the reason?
