Firefox Support Forum

Hello, I've followed Firefox's invitation to install and update the browser on my Mac. Unfortunately the new version is not compatible with OS 10 El Capitan, my operating system, so now I can't use Firefox at all. How I do get the old version back?

Thank you, Lars

Dear Community, I love Firefox but here is how fonts now look like on my old MacBook Pro (v10.13.6). Why is this? How can I fix this? My Firefox version is up-to-date. As shown on the screenshots below, on Chrome fonts appear to be normal. Thanks so much for your guidance!

I have Firefox on an old MacBook which hasn't had its macOS updated for a couple of years, and a new Mac running up-to-date Monterey. In both, Firefox has just developed the same problems at the same time: pages won't load, and the program won't shut down normally -- I have to use force quit. Safari works fine and I've tried all the usual solutions, bar deleting and reloading the app. I don't want to do that yet since the problem is the same on two different computers and an old and a new macOS. Since Firefox has recently updated, has that caused the problem?

edited iOS to macOS as iOS is a mobile OS for iPhones and moved thread to (desktop) Firefox section.

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.

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?

I'm on a Mac desktop. Favorite Bookmarks have stopped displaying in View > Toolbars > Bookmarks Toolbars (set either to Show All or Only Show on New Tab. I have verified the favorites are still there in Bookmarks > Bookmarks Toolbar, but when View > Toolbars > Bookmarks Toolbars is opened it displays an empty bar.

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!

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 have consulted https://support.mozilla.org/en-US/kb/how-do-i-restore-my-tabs-last-time. That article says:

-Click on the menu button [three lines at the upper right] to open the menu panel. -Click History. -Click Recently Closed Tabs.

I am using Firefox 95.0.2 for Mac (iOS 10.15.7). There is no "Recently Closed Tabs" option to click after clicking on History per the above instruction. I have saved various files from the time of the crash, in particular "previous.jsonlz4" (a 20.6 MB file, as I had a very large number of tabs open). Is there any way to use this or some other file to restore my old tabs?

I recently upgraded to the newest version of Firefox for iOS (version 96.0.2). Is there any way to change the background colors of the Home page and other windows? I find white characters on a dark background hard to read and would prefer black characters on a light background.

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?

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?

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!

Thank you to the kind replies I received on how to sort my access to

Disneylivecams.com.

However all replies must relate to pc options and not mac as the headings are not there in mac as the kind people have asked me to look for

Any other Ideas please

Fix this bug ASAP - I can't get to any new sites on FF 98.0.1 since it updated yesterday! Need to go to the link I clicked in an email in a new tab. URGENT! On a MacBook Pro. Has worked fine for years, til this update yesterday.

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.
