i recently lost my computer to destruction. i have a number of files saved by Mozilla backup on a thumbdrive. i have several backup files dating from 2014 all the way until now. after re-installing Firefox on a new computer, i tried MozBackup to restore my old Firefox from the latest file dated a coupla of months ago this year. the files have names like Firefox 16.0.2 (en-US) - 2013-01-05.pcv or .pfc. when i tryt and load it into backup it saysit isn't a valid backup file. how can i get this to work?

For years I’ve had no difficulty accessing online my HSBC bank accounts in UK using Firefox. In recent days they have changed their security access method whereby their site now requests a security number generated on one’s phone using the HSBC App (it used to be a random number from an HSBC supplied handheld device) which then has to be input via my Windows 10 PC to access my data. If I use Microsoft Edge as browser, everything works fine, but when I try Firefox my system just hangs after I’ve put my bank ID into the HSBC opening page (the first security step) and simply never opens the next HSBC page which would ask me to generate the said code on my phone. Seems a browser related problem. Any ideas why Edge works but Firefox does not?

I am trying to use a new HP Spectre laptop which will be my all purpose home computer. I selected Firefox Browser as the default browser but I don't believe it has ever come up as my browser. It is loaded among many other apps (?). I used to call them programs (?). I get Edge, Chrome, Bing, and others, none of which I want or ask for. They just seem to appear randomly.

Hello, I have encountered a lasting issue: Firefox' telemetry collection process causes a cmd window to pop up briefly. The windows sometimes lingers a split second later, and if I accidentally click it at that time, whatever program I'm in will get minimized and I'm back on the desktop with cmd window at front. You might want to have a look at that, I disable my telemetry for time being. Firefox version is 99.0.1 (64 bits), operating system is Win10 10.0.19043. Respond for other data you might need. Best, Michal

A subscription service I purchased (Kine Mania TV) has on several occasions gone to a porn site. I have enjoyed many hours of wholesome TV series and movies at Kine Mania TV - but HATE it when smut shows up instead! Please advise - this is scary stuff for an old lady. I took screen shots of the web address if you need me to provide. Nadeane Mannion

something new-- I can't sign in to my att account like I always have. I can still log in on older win 7 and android devices. Only this win10 desktop is now having problems today. Any suggestions?

I use Kaspersky for my internet security. I choose the 'Safe Money' option for many other sites...but cannot connect sign on with my bank. Because the page always comes up asking for me to choose a browser. I down load and update the firefox site. This does nothing except giving me multiple firefox updates! What is happening and how can I stop having this issue pop up? The other sites on 'Safe Money' are not banking sites, but still need security. Do I have to change browsers? I can be reached at [email removed from public]

Thank you for any help in this matter

with firefox, drag and drop for attachments is not working using macOS High sierra, and outlook emails. It works ok in Chrome but I dont want to change over. I deleted cache and cookies and restarted. It worked ok for a while but stopped working agaiin.

I went into setting and Firefox is not on the list of defaults. I think the issue is that I downloaded Firefox through the website and not the MS app store. Because when I open the "Look for the app in Microsoft Store" tab on the default list, it opens the store and lets me download Firefox again. I wouldn't mind doing this but it downloads it to my C drive and I need it on my F drive because my C drive is my SSD and is used for only Windows and because Windows keep getting bigger and bigger, I am running out of storage on it. When I try to move the newly downloaded Firefox to my F drove through the "Apps & Features" menu where you can uninstall apps. It tells me Firefox can't be moved. So there seems to be a communication error between windows and the none app store download.

The pics show the default option first with Firefox downloaded from the web not being there (setting 1), then Firefox being there (setting 3), and last the failure to move the files to the F drive (setting 2). Any help would be great. Thanks.

Firefox asked to refresh, as it had kept crashing, I did. I see the 'Old Firefox Data' file, on my desktop, and then followed the instructions to about:profiles. Then I opened the Local Directory, right click and pasted. I then restarted Firefox, and I got nothing back. Help! Thanks!

I am sending tabs from Firefox mobile to Firefox desktop (Arch Linux) (on a regular base for years). All worked fine. After a new install two weeks ago the Firefox desktop receives the tabs and opens them as supposed. But after a day or three when I open Firefox desktop it opens all previous tabs again together with the newly sent tabs. I deleted the Firefox profile and installed from Firefox sync but the problem occurs. I deleted all devices in sync and added my 2 devices (desktop and mobile) again but it didn't work. Does anybody have a similar problem (and a solution)?

My firefox browser is completely unable to load any tabs. The search bar works but screen remains blank after pressing enter, I have tried uninstalling and reinstalling with no change. Thank you any help
