Forgot Primary Password Or Never Had One in the First Place! I Don't Know Or Remember Regardless I Can't Log in! Can You Fix This For Me Please ? I Can't Fix It at my End At all! I Try Only To Fail!

For the last maybe 2 weeks of so I have been able to play videos on any website,it is only Firefox that is having the errors. I use Windows 10, and the only extension I have is password managment

I have tried: 1) troubleshoot mode: no changes 2) clearing cache: no change 3) making a new Mozilla profile: no change 4) lowering/turning off security protections 5) refreshing from uninstall 6) uninstalling and reinstalling 7) Allowed autoplay of media 8) toggled off drm

The primary sites that I use are; HBO - error 1K-003 Twitch- error#4000 Patreon- doesn't error out, but just goes black on player Dropout.tv- player error YoutubeLive- Browser error

I cannot see the Fifa 2026 at this : https://www.sbs.com.au/ondemand/watch/2498306627540

There was nothing wrong everything was running perfect and smooth but then out of nowhere my youtube froze and I couldn't press anything on youtube tab, I could still close it or press the buttons on the sides/corners but on the youtube, it also doesn't refresh, this only happens on youtube and only on firefox when on other browsers, yes I unchecked hardware acceleration, I restarted my firefox many times, I cleared the cache, today I turned my adblockers too, i thought it turned into how it was before but then it froze again and now I couldn't even see youtube it was just black screen on that tab, like what do I do here, do I switch browsers? It eventually starts playing again after I wait for some minutes but I don't want that, I want it to work like how it did before this happened. Why did it even happen?!

My Firefox book marks have disappeared. The toolbar is open but has nothing to display.

I've gone to my Firefox Library window, but the entire page is blank. The table gives no entries for Name, Tags, or Location. Lines below (Name, URL, Location, Tags, and Keyword) are empty.

Searching my MacBook Air I found my Firefox Profile folder. In it there's a folder ending in "default-release". That folder contains a folder called "bookmarkbackups" containing files with titles indicating recent backups.

How can I restore my booksmarks?

Hi everyone, my website YouTube Thumbnail Downloader

is not loading properly on Firefox, while it seems to work on other browsers. Sometimes the page loads partially or shows styling issues. Has anyone faced a similar problem, and what could be causing it? Any help or troubleshooting suggestions would be appreciated.

Hi,

I'm seeing a strange issue in Firefox when using an online work-hours calculator for payroll calculations.

On this page: https://mauricettecalcul.fr/

When I enter certain hour and minute values and convert them to decimal hours, Firefox occasionally returns a slightly different rounded result compared to Chrome on the same machine. Because these figures are used for payroll, even small rounding differences can be problematic.

I've already tried clearing the cache and testing with extensions disabled, but the behavior remains.

Has anyone experienced browser-specific rounding or calculation differences in Firefox with JavaScript-based calculators? Is there a way to identify whether this is a Firefox issue or something related to how the site handles numeric calculations?

Thanks for any suggestions.

Hi, I enabled the included Firefox VPN, but it only allows you to choose an entire country, and not very accurately or reliably. The help pages direct me to use Mozilla VPN to do that, so I enabled it, only to be told it's only available on Windows. How can I set my location to something else for a website on a Mac? Thanks.
