I just bought a new computer. How do I sync firefox on my old computer with firefox on my new computer. The same for thunderbird mail. Please help. I am not a computer genius. Dave Muran [edited email and phone# from public community support forum)

Please return my Computer to using Firefox default as my browser as it was 2/01 /2026.Ive tried several times to do this w/o success . I was using windows 11 and have been trying to get rid of MS365 which I never used but have been charged for a solution , but have been blocked and refused cancellation after they asked me to change my email address and PW . Insanely confusing !

I have used Mozilla Firefox as my default browser, for years. Recently, I used a program to clean (what it said was) junk files from my computer. Unfortunately, I did not make a rescue point. After removal of the files, several of my programs, including Firefox, has no longer worked as it once did. I was always able to go into settings to select my browser, my search engine, my home page, etc. That is no longer possible. I was wondering if I should uninstall Firefox and reinstall - or is their another easier way to repair my problem?

Any help I can get is much appreciated.

Is this the only way to send thunderbird an email??? If it is that's OK. I am a fairly new customer of Thunderbird. I have a new laptop and want to find out if Thunderbird has any questions forb me to answer. I think my password is OK, cause I signed in somehow.

I am getting repeated pop up "alerts" from Firefox, McAfee and others about Trojan Horse and other viruses. I did not click on the links offered. How do I stop them from coming?

I have an Intel I5 PC that runs MS Win XP. The reason that I'm still running that ancient OS is because of whats inside it. I have two old boards in it that I still use and quit honestly can't afford several thousand dollars to replace them. And the new machine to go with them.

I need to get online to download the few pieces of software I need That are still out there. But like most sites they examine your machine to see what versions you need and it's a download and install package. So I can't use a different PC.

My question is: Is there a version of Firefox I can download that will work on XP, and not be ignored like is done to IE 8. And that I can then transfer to the XP (service pack 3) box for installation?

Following a recent Firefox update, 1.48.0 I think, the search box in the middle of the page no longer works, any attempt to type there ends up in the address bar. I have tried setting "browser.newtabpage.activity-stream.improvesearch.handoffToAwesomebar" to false and other suggested fixes on the internet but it made no difference. I am running Windows 11 Pro, fully updated. Hope you can help Regards Keith

When I tried to log in to my account earlier today, I found that it was gone. I used my recovery key to create a new password and now lost all data, passwords etc. What do I do now? Why did this happen? I am not very computer literate but have tried all of the suggestions in your help forum and nothing works. Nothing has changed on my computer since my last login yesterday. Firefox is my home page and browser.
