Firefox Support Forum

Hi i connect on this website:https://www.online-tech-tips.com/computer-tips/how-to-remove-default-microsoft-apps-in-windows-11-10/

and the videos play automatically with the autoplay block on firefox, thank you for your help god bless.

I recently accessed Firefox Monitor. Living in Australia we had a large Data Breach from Optus (Phone carrier) in Sept last year. Yet it was not litsed in your list. Please advise

Windows 11 keeps trying to change my browser from FF to their Edge spyware/virus (it asks EVERY time I start FF). I managed to get it stopped once - difficult and time-consuming, but the next Windows update re-installed it. I have used FF for 15 - 20 years and it works superbly for my needs and nothing from MS ever seems to work.

How can I stop this?

Thanks, Wolfgang

Firefox fully updated for fully updated Windows 10 21H2 on HP Envy, 16 GB ram, Intel(R) Core(TM) i7-4770 CPU @ 3.40GHz 3.40 GHz. Only trouble known is that suddenly FF would not operate the Ancestry.com properly after years of everything operating just fine there. Finally swapped browsers to Chrome. That works 100% ok. My problem is that I want to use Firefox not Chrome.

Not exactly sure why but the browser is no longer working for my banking. I first noticed it a week ago when I tried to log in and then ended up calling the bank tech support. They told me to use google chrome instead. I have been using Firefox for years and never had a problem. After researching for latest update changes, I tried changing the settings to allow cookies for the session for the bank but this did not work either. Any idea why this is happening? Thank you. Tony.

I wanted to provide an update for a closed thread I opened ~3 months ago. That topic can be found here:

UPDATE I reinstalled Windows - "downgrading" to Windows 10 - same problem; videos of any sort from any source did not play in Firefox, sound or anything.

Firefox now plays videos after navigating to the .exe file, turning on "Windows Compatibility Mode", and setting it to Windows 8.

So a while ago I opened firefox on my computer and noticed all my bookmarks were dead (they had the globe and wouldn't go anywhere when clicked), I thought 'weird' and didn't do anything at the time because it wasn't what I was busy with at the time. Then, recently, I open firefox and my bookmarks are linked wrong. Like, I have Netflix bookmarked, it says Netflix, it has been netflix for as long as I have used Firefox, but if I click on it, it takes me to an article I read weeks ago at this point -one I did not bookmark or even view repeatedly. In some of my folders all of the bookmarks are missing, like they aren't dead, they're just gone.

But if I go to my ipad firefox and access my desktop bookmarks from that sync -which I literally just re-synced today- I have all my bookmarks. All of them exist, the links are fine, they're there. But I have tried refreshing Firefox, uninstalling and reinstalling it, restarting my computer, logging out of my account, removing all my extensions, everything I can think of and! Nothing!

Also, if I try to restore my bookmarks from an older file, it does nothing. Or it will say it can't access them.

I don't know what's going on. I know if I wanted to I could go through and re-bookmark them all because I do have access to all of them on my ipad, but I mostly want to know if there is a way to fix it on my desktop or even figure out what happened. I can't remember anything happening around the time with my browser. Any help is much appreciated!

Since this took me awhile to figure out I thought this could help other people.
