Firefox Community Forum

This problem just began today on my Win 11 laptop. Firefox is current - 139.0.4. Win 11 is current. No new software has been installed. Firefox hangs up and will not move. Task manager shows FF is consuming more than 90% of my 16GB memory. I must end the FF task to get up and running again.

I just got a new Epson 3-in-one printer and tried to sign up for the warranty. I got a message that the warranty was expired... I went to the Epson support site on Firefox and Malwarebytes blocked the site as malware... It said I could add the site as approved, but I don't know how to do that. "https://www.epsoncom.com/my-account/home". The Epson site said I already had an account but my password was incorrect. I had an Epson printer more than ten years ago; I don't remember the password and they don't provide an option to reset it. HELP, PLEASE.

Google suggestion in Firefox's address bar keep showing Japanese suggestions even though I chose English and Canada as language and location with my google account.

I use same google account with google chrome, but google chrome doesn't show Japanese suggestion.

As for setting on Firefox, I unticked other than "show search suggestions".

How do I resolve it?

Thank you.

Hello,

I'm a bit out of ideas how I can get Firefox to display the correct characters. For reference: https://learnjapanese.moe/font/

Windows: I only have german and japanese locale installed, i even changed in intl.cpl the language to japanese. I have installed the japanese language pack / fonts and it's showing correctly in any windows editor.

Firefox: Second language set to japanese, disabled all addons, tried it on private mode to no success.

Any ideas how I get the characters to display?

Edit: I made it work by changing in about:config the font.cjk_pref_fallback_order-string to have ja as first.

I'd like to ask about Firefox's behavior and settings. I'm using Firefox with vertical tabs (using an add-on), but it seems to be behaving strangely. The things that have changed since before are: 1. Open from pinned tab 2. Now opens in a new tab → Previously it opened in the same tab 3. Clicking on a newly opened tab opens a new tab again → Previously it would open pinned tabs/same tabs → in a new tab It has changed. I haven't changed any of my Firefox settings. Windows 11 Home 23H2 Firefox version 139.0.4 (64-bit).

Periodically I open Friefox and all my cookies have been deleted. I go into settings to find "Delete cookies and site data when Firefox is closed" has been checked (NOT BY ME!) again. This is very annoying as I then have to log into all my websites and go through 2FA. This is annoying to the point that I am posting on this site for help. Next step is find a new browser that doesn't screw up my work-flow randomly for no reason.

See the attached. I get these despite having search suggestions disabled. I even turned it on long enough to uncheck that grey-ed checkbox. Made no difference.

Thanks

The AI chatbot is back in my sidebar. I did not opt in to this. I would prefer not to roll back to whichever version of Firefox is before the AI it's-a-feature-not-a-bug got wedged in; what other options do I have for permanently disabling AI?

Going to sidebar settings to hide the AI chatbot does not suffice. Evidence: I did that already, it has been undone, and I cannot now find the toggle in question.

Personally I vote for yanking it out of the main browser altogether, so people have to actively choose to install the AI chatbot add-on. But my question is about actions I can take myself.

hi for some reason twitch.tv or some other websites will no longer play videos on my pc and i have no idea why, firefox works fine on my laptop

The comment sections for foxnews.com and other sites disappeared using Firefox but not when I switched to Chrome. This just happened 6-18-25. Before this date, it worked on Firefox.

Every time the browser autofills a password it asks me for my Windows password. I don't want this behavior, as this makes password autofill completely pointless. How do I disable this "feature"?

i recently disabled 2fa and installed a new authentication app: Ente Auth. i keep getting invalid code each time i enter the generated code. i tried both options, scanned the QR code and entered the secret key manually. i used authy with success as my auth. app with firefox but can't use authy anymore. keep having issues setting up 2fa with other auth apps. thanks for any help you can offer. peace, Adrian

My Win10 & Win11 pc's updated to this version and they all have the same problem: The bookmarks have disappeared. Including my pinned bookmarks on FF's opening page.

I also just noticed that there are no "toolbar items".

Today (06/12/2025) upon opening a new tab, Firefox slid the new option of uploading a custom picture to apply to the background. Tried the new feature, now I can not find the setting that allows me to change the picture. I read the thread "Customize your wallpapers". The instructions are as follows; You can personalize your Firefox New Tab page by adding one of the available wallpapers. Follow these steps:

  1. In the right corner of the New Tab page, click the gear IG settings icon.
  2. In the customization panel, under the Wallpapers section, you will see different categories like Solid colors, Abstract and Photographs.

       Click the category you prefer. For example, selecting Abstract will show a variety of abstract designs. 

The problem I have is the customization panel is no where to be seen, I have click on EVERYTHING possible, it is not in my settings, why? How do find this?
