Firefox Support Forum

Hello

Hoping someone can help me with this asap.

I was prompted to update firefox on my mac laptop.

So I did the update by clicking the button available at the top of the firefox browser, but now I can not open Firefox at all.

When I click on the firefox icon it does not open firefox and this message appears: You can't use this version of the application "Firefox with the version of OS X. You have OS X 10.11.6 . The application requires OS X 10.12 or later.

I understand what this means but not sure how to revert back to the previous version of firefox.

When installing the new update/version of firefox, i have deleted the old version of firefox.

I am following these instructions currently to try to resolve it: https://www.wikihow.com/Downgrade-Firefox

Following the instructions above I went to: https://ftp.mozilla.org/pub/firefox/releases/ , but can not find the previous version of firefox that I need.

The only info I have on firefox is version 102.2.0. I am after the version before this as assume that is the one compatable with my laptop currently (i can not update the OS ).

Can you help me download the previous version so it is compatable with my mac laptop?

Thanks for your help in advance

Hi there,

I am using the current version of Firefox on Mac Os 13.1. When I try to copy a formatted text (e.g. from Pages to Google Docs in FF), the browser deletes all formatting. It is plain text again.

I don't have this problem with any other browser like Safari.

I have already tried troubleshoot mode and to refresh my profile. Unfortunately I still have the same problem.

Any suggestions? Thank you in advance and all the best!

When I click to open a dropdown, it opens and then immediately shuts back up again. I have to maintain pressure on the left click to keep the box open. Any ideas?

When trying to open the Firefox icon on my computer I was told cant I open the application “Firefox” "because it may be damaged or incomplete." SOMEHOW HAVE NOW GOT AN ICON MARKED FIREFOX 2 AND MANY OF MY IMPORTANT BOOKMARKS HAVE DISAPPEARED

Starting a few weeks ago, firefox would not load any accounts via https://login.microsoftonline.com/ one one of my Macs.

I was running the latest version 121.xx on MAC 12.7.2

Nothing would fix the site issue, so I tried re-installing and refreshing Firefox. Followed all the troubleshooting steps.

Now firefox is completely broken. Tried creating a new profile. Running in safe mode, etc.

It sometimes will load pages, but extremely slow. But generally is unusable.

Firefox works on my other macs just fine (Profile uses sync with those machines)

Safari and Chrome work perfectly fine. No malware. No ISP issues. No firewall.

Please advise a fix or I guess I will delete everything firefox related.

Oops. I replaced my version of Firefox with the the newest version, but my OS X El Capitan version 10.11.6 does not support it. Now I can't browse with Firefox. How may I get the compatible version back?

I have been noticing that Firefox browser is being manipulated to obtain confidential information from users.

Is Firefox doing anything to stop this? The crooks who are most likely military and Others affiliated with the government are surreptitiously accessing US Citizens computers and silently obtaining credit card information, banking, Venmo, Zelle Apple Cash, etc. and ROBBiNG citizens.

This is no joke. is Mozilla doing anything to protect their browsers from these hoodlums and corrupt government officials and there hired contractors?

The people you trust are not to be trusted.

This is happening every few minutes now. It started right after the 97.0.0 update. The 97.0.1 update doesn't seemed to have helped.

I don't use any browser extensions.

I never saw this issue before, and I have been using Firefox as a primary browser for many years. I'm on a MacBook Air, M1.

Problem: "Video cannot be played on your device as it does not meet content protection standards" Message when trying to stream videos but only on Amazon Prime.

I have searched the internet for an answer only to be told the problem lies in the browser. I find this confusing because a few months ago I was always watching Amazon Prime videos on Firefox browser. What has changed? How can I correct it? I have the latest Firefox update (108.0.1 64 bit) on my mac Book Pro, MacOS Ventura 13.1.

Thanks for any help you may be able to offer,

Happy Christmas,

Pete

Have been receiving security alerts for the past month or so. Now firefox is restricting my access to my printer due to a possible security problem. I have also seen an alert that a certificate for use expired last month. What can I do, or who can I talk to (cannot find any support phone number.

Every time I open a new tab or go to a tab that I have open, when I come back after my computer has been asleep and try to search for something or refresh a tab, it will give me an error message. I have to close the tab and search again then it works, sometimes I have to do it 2 or 3 times to get it to work. This just started happening with MacOS Catalina 10.15.7 and FireFox 103.0.2 updates in the last few weeks. I tried restarting my computer and I deleted the Firefox app and reinstalled but nothing helps.

HI FIREFOX! Many websites are not readable. I can see these correctly in Safari. I tried getting the latest Firefox updates. It did not fix the issues. Bizarrely, I can paste into another application and read the gobblity gook. So I think it is just a font issue. I really do not want to go back to Safari. Poshmark and Fedex are the two websites I experienced issues with today. Fedex would not interact properly with Firefox but I could find my tracking information on Safari. I have had the problem previously but did not have time to look into it that day. 16" Macbook Max M1 running Monterey

Hello. I would like to use Firefox on my Mac, but my processor is a 2.7 GHZ Quad-core Intel i5 and I would want to download the Vidiq extension. I have checked the other system requirements and they are fine.

Will Firefox work with this processor? Would the Vidiq extension work ok?

See subject above. Their instruction doesn't apply to my mac. I like weather.com, but not enough to pay for it and I can't get past their screen with their instructions while on Firefox. I don't have the symbol they want me to click. It just happened today.

Firefox is wreaking havoc with my 2018 MacBook Air. It seems to have been invaded by gremlins that are eating RAM and slowing down the works, sometimes causing my laptop to shut down.

I want to delete Firefox and reinstall, but first I want to save all of my cookies and other settings. (I've already downloaded my bookmarks.)

How do I save my cookies and other settings?

thanks very much. Sandy
