Hello,

In the DevToolbox, the “Copy all as HAR” and “Create file...” functions are not working. It seems that in both cases, only empty space is placed in the clipboard and in the file (this has been happening since the last update).

Thank you in advance.

I have clear search history when browser is closed checked, and it still has a months worth of history and I have closed and reopened the browser countless times, why doesn't the history clear?

Ok so I never made a proper backup with Mozilla/Firefox I just dumped the whole Appdata folder on a HDD as I wasnt fully sure what I needed before a reinstall

Now after my reinstall (Still got old windows working on another HDD) I put back the appdata but I cant get my passwords or bookmarks to appear again. Did I mess up?

Bonjour, Suite à la mise à jour MOZILLA du 14 Septembre 2025, j'ai perdu tous mes mots de passe dans " menu de l'application ", j'aimerais pouvoir les récupérer. La dernière mise à jour qui a été installée est 144.0 (20251009125714)

Dans l'attente de votre réponse Cordialement

When I try to sign into Amazon, windows needs a passkey that is requested by Mozilla....I never set this up or wanted a passkey and I don't know how to get around it.....I am completely locked out.

Hello I have Firefox 144.0 (64-bit) installed. I added Video DownloadHelper to Firefox, but its icon doesn't appear in the Firefox toolbar. I've tried using Toolbar Customization, but the Video DownloadHelper icon doesn't appear there either, so I can't drag it to the toolbar. Can you help me put the Video DownloadHelper icon on the Firefox toolbar? Thank you

after updating to the latest version FF kills my net connection after loading. edge and all of my other apps are working fine. i am typing this on edge.

i have a lot of FF tabs but that has never been a problem in the past.

Even though I've given permission for pop-up windows on outlook.live.com/mail, I have to give permission for each pop-up. I use a Dell PC and Windows 10 (with extended updates to 2026).

The Firefox notification closes, but returns the next time I open the Outlook tab.

Can this be fixed?

Thanks.

For the past few months, I have had a problem with my computer - it seems to try to write to a hard disk (sounds like whirring ) and the keyboard freezes up for a few minutes, when whirring in the computer stops. I have taken the computer to Geek Squad two times and they said they found it, but it still happens.

I have just tried Google Chrome and Microsoft Edge and I haven't noticed it. Is this a problem with Firefox or just coincidence?

I can not find the add-ons in firefox I have looked exactly as directed and it is not there.

You can help by telling me how to make it show up lie it is supposed to.

Hi,

In the last two weeks, I cannot access Outlook live via Mozilla (it is fine on Chrome on the same pc, although I prefer not using that) - it comes up with a 403 error. Also, but for slightly longer (maybe 3 months), I cannot access Canva on Firefox, as it comes up with a 'This browser is unsupported, download the desktop client. You are using an old version or a browser that we do not support. To continue using Canva, please download the desktop client. Download for Windows 10 or later' page.

The only way I can access Outlook and briefly access Canva (apart from using Chrome) is to clear all history - cookies, cache, browsing etc. If it were a matter of doing this once, it would be a ball-ache (who wants to type in their user name and password repeatedly to every single website you use habitually?), but I could deal with it. But it is every time I close my pc down and reboot.

I am not uber techy, so please be kind and provide super easy steps an idiot could follow. Many thanks

PS am on a desktop PC running windows 11 Pro vers 24H2.

A few days ago, my Firefox browser stopped clearing browsing data, cookies, history, cache. I am using a custom-built desktop computer with Windows 10 Home, Firefox v. 143.0.4. What is the setting I need to change so this will start clearing data again? The "Clear data and cookies" no longer works, and my search has brought up no other options that I have found. I need simple instructions, please.

Mozilla Corporation is sending me a box message from Nsv353A.tmp published by Mozilla Corporation teeling me to sign in to Amazon What is this?

And how do I fix this?
