Firefox Community Forum

I want to confirm that Mozilla Firefox is my default browser. I want it to appear when I start up my computer and have it appear on my screen when I'm at rest. But first, I need to set the page up again.

(When I hit "browse" below, Firefox does not appear. My documents file opens up, wanting to save something to a file or folder.)

If needed, my email is [edited email from community support forum].

Thanks.

I am unable to find an answer (hours on the Internet) to this specific problem that has appeared out of nowhere:

Under File in the Menu Bar the "Email Link..." does not work anymore. If I want to send a thing I'm looking at to my Thunderbird email (and which I use Hover), most often is a You Tube video. But I do this for other things I start reading, but I don't have time for. This has worked for a very long time. It was always so easy. Now when I click on Email Link all I get is a blue circle-I think it rotates sometimes. It disappears in a second or less. I get nothing.

I do have Windows 11 and up-to-date Firefox. I am fairly sure it continued to work after I got a new computer Nov. 4th with W11 on it. I believe I lost this function within the last 6-8 weeks. Maybe with the new computer, but I don't think so. I'd appreciate it if someone might have a fix or idea about this. I admit my intelligence is not up to the task!

Hi,

My Firefox data (profiles, bookmarks, browsing history, etc) suddenly disappeared. I had a session going with multiple tabs open, and only noticed because Outlook kept opening links in a brand new session that was not linked to the one I already had open. When I closed out of firefox, my old session and all my data was gone. I followed all the recovery steps and am stumped. Where did my data go and is it possible to restore it?

Thanks!

Love Firefox, and like Avast software. Wanted to try Avast AntiTrack Premium but Avast wants me to make it an add on extension to my browser. Mozilla told me this- just want to know if it's safe. TIA This add-on is not actively monitored for security by Mozilla. Make sure you trust it before installing.Learn more Preview of Avast AntiTrack Avast AntiTrack

I talk to friends on facebook/messenger. Previously my conversations were always on Firefox. But suddenly a couple of months ago I could no longer use my camera and my microphone on Firefox, and had to install a new browser. I have been trying several times to give Firefox permission to use my camera and my microphone, but sofar without success. What do I have to do?

Even when I am signed into Firefox, the other person's Firefox passwords appear, and mine rarely do. This happened even before I downloaded Windows 11 recently. Often, I need to make sure the other user is logged out of his Windows acct., then turn off the computer, wait a few minutes, and then turn the computer back on before my passwords appear. Today, even that hasn't worked.

i run Firefox on Win11. When i go to a website, and open several tabs, e.g., 10 or more, firefox just sits there and no longer works on that site. Basically Firefox is becoming quite worthless as a browser for me. The reason i use it are the extensions. This is something that has happened within the last 6 to 9months or so. What is going on. Is there now some limitation of how many tabs you can open? The site with this problem is: https://www.bellazon.com/main

Anyone got any ideas as to what is going on here?

Hello all! In this Firefox on Windows 11 setup I only have a few add-ons installed: Bitwarden ClearURLs Cookie AutoDelete DecentralEyes I don't care about Cookies PrivacyBadger uBlockOrigin

I sometimes have an issue: when I try to pay for a product or service, I end up in an error page and the only way to continue is by using another browser. I think that the problem is that my browser blocks pop-up windows. Which of the extensions does that? How can I get myself out of the need to use other browsers?

Thank in advance!

certain web sites are not available on my PC via firefox browser. Have to switch to Edge to access. Have had this happen a number of times for different websites but was amazed that couldn't access social security admin (ssa.gov). Received this error message:

By default ALL BOOKMARKS BACKUP saves on DESKTOP (Windows 11 pro). How can I change where the *.json file is stored (downloaded). I want D:\ZTEMP as the place to save all downloaded files as in settings "Files and Applications" "Downloads" "Save files to" D:\ZTEMP for me. example bookmarks-2026-01-03.json is placed on DESKTOP; I want in D:\ZTEMP. Thank you.

I am not familiar with settings, therefore I am unable to get a few of my pogo games to work. One of the games is Jungle Gin., no cards. On the Browser EDGE I can play Jungle Gin. I have been told it is a software problem with Mozilla. Please fix it for me. Thanks

Every time I close and reopen the browser (and then check the Process Manager), all my pinned tabs are there and taking 20-30 megabytes each while I didn't click on them and they're supposed to be unloaded after startup

None of the unpinned tabs are in the Process Manager

How do i stop this?

For a couple of days now my cookies have been getting deleted or corrupted every time I turn off and back on my computer. The only temporary solution I've found have been to delete my cookies.sqlite file, copy cookies.sqlite.bak and renaming it to cookies.sqlite. It is very frustrating to lose all my extensions, my cookies, my bookmarks and logins to my usual websites. I am using Firefox version 146.0.1, on a Windows 11 computer running version 25H2. Also, my original cookies.sqlite file is 512kb while my backup is 2048kb exactly, if that is useful in any way. How can I fix my issue?
