So I recently installed Firefox beta. It installed on top of main firefox. Now I am in beta version 84 but if i try to open regular firefox release version 83 it says running an old version will corrupt profile data. It just has an option to create a new profile, so i am asking if there is a way to import my settings from my original profile or make my original profile run on version 83 or should I just wait for version 84 to be released in main firefox.

How can I get my settings and bookmarks from a cloned image of my old HDD. This is pretty annoying and making me think about leaving Mozilla. I've done what a support page advised and copied my data from one 'profile folder' (from the image) to another (internal drive). Not helping and displaying a 'The bookmarks and settings will not function properly' error message. I did not unfortunately create a proper backup prior to transferring drives so can't restore that way, assumed that things would more or less be a seamless sync through my Firefox account.

Would appreciate help here thanks.

My profile folder is C:\Users\hseib\AppData\Roaming\Mozilla\Firefox\Profiles\pftm4b0j.Default User. It is the only profile under "Profiles". When I open the file "pftm4b0j.Default User" it looks like all my data successfully migrated from my old PC. But when I launch Firefox, no bookmarks, no passwords, no add-ins, no nothing. Any help welcome.

At some time in the past I installed regular Firefox and updated throughout the years. But for the past maybe year or so, the updates have been Firefox ESR. I don't recall ever having installed the ESR version. Why am I only getting Firefox ESR updates?

I am using Firefox Nightly. It receives updates every day, but most of the time I cannot restart Firefox as soon as update is available. I want to delay it till next natural restart (ex.: night), however, Firefox shows notification about the available update. It's a minor issue, but seeing notification every day and having it to close every time gets annoying very quickly. I want to disable update notification but keep automatic updates. How can I do this?

I use Scenesource to download items of interest, after scrolling down to find what I want, the settings do not allow me to get to the last page I started from and goes back to the first page. I know that I found the setting before but at my age I cant seem to get to it anymore. Can someone tell me how to get that back?

I followed the instructions on the support pages to transfer my profiles from an old W7 laptop to a new W10 one. After the copying of the profiles to the correct locations neither Firefox nor Thunderbird would start complaining that they could not find the profiles.

What I did (same thing for Thunderbird) 1. Opened Firefox troubleshooting on the old W7 laptop, opened the profile folder. 2. Closed Firefox 3. moved two levels up 4. copied the Profiles folder to a usb drive.

On new W 10 laptop 1. Opened Firefox troubleshooting on new W10 laptop, opened the profile folder. 2. Closed Firefox 3. moved two levels up 4. renamed the existing Profiles folder to Profiles OLD 5. copied the Profiles folder from the usb to the same correct location on the new laptop

When I tried opening Firefox on the new laptop it would not open complaining that it could not find the profile. Firefox had opened correctly previously.

Then when I renamed the moved Profiles folder to Profiles NEW and renamed Profiles OLD to Profiles, Firefox opened normally on the new laptop.

Identical procedure and result with the Thunderbird profile transfer.

What should I do?

Thanks.

This issue is occuring for couple weeks now. When i click download nothing happenes. No matter what i try to download, it wont work. I do my downloads in another browser :D Why is that happening? I did reset firefox by the way and there were couple downloads and then it broke again. I have this add on saves backup automaticly and here we can see there is something wrong because it cant save the file.

Hi! I'm trying to import my passwords from Chrome and I can't because there isn't the option, like it is described in this tutorial. https://support.mozilla.org/en-US/kb/import-login-data-file

What can I do?

I have downloaded the latest browser today. I can access my Yahoo Mail, but I cannot delete or send any mail from it when using this browser. My Yahoo Mail is now useless when using Firefox. Please advise me of the solution to the problem as soon as you can.

On my MacBook pro running macOS Catalina 10.15.7 (most recent version) Firefox crashed after an update around one hour ago. I've uninstalled Firefox in the end and downloaded a new one from the site. I get 'error code - 36' over and over, see attached screen shot. I've downloaded Firefox on various different browsers, bat always this same error code. Always enjoyed Firefox without any hiccup up to now! Suggestions anyone? Thanks. Chris

Hello, is this the standard behavior for downloading the FF by using some different web browsers? I am talking still about the same version of 64bit FF for Win10 offline installer US but downloading this in different web browsers... The (final) downloaded file has exactly the same size of file but "slightly" different content - this is happening only when downloading FF. If I download different browser in various browsers then the size and content is exactly the same - but not in case of FF. Is it OK (some adjustemnt..) please or could it be virus? Thank you in advance for your respond. Jiri

i have lost everything and struggling to get all my bookmarks back after a update from firefox- HELP! Is there a number where someone can talk me through this as I cant seem to sort it from the support pages

I'm getting the XML Parsing Error message on Firefox after the latest update. I have tried every fix I can find in the help guide and the community section but none of them have worked. So far I have:

- completely uninstalled Firefox and everything related
- emptied cache of Chrome (which is what I am using to re-download Firefox)
- deleted everything in Windows Temp folder
- re-downloaded a brand new download of Firefox directly from the site
- run a full clean re-install of Firefox (same error message)
- restarted the computer (still getting XML Parsing error)
- unable to start Firefox in safe-mode as I don't have the button on the browser to do so.

Any other suggestions would be greatly appreciated as Firefox is my favourite browser and I want it back!
