have mac 10.10.5 -tried to install newer firefox browser (not compatible) and in process lost old version of broswer and all bookmarks. Can find and reinstall original browser and regain my bookmarks

I'm buying a new computer and I'm wondering is there a method/procedure that I can use to transfer the entire FF browser including settings, extensions, bookmarks, and passwords without having to reinstall all those items individually? I know I can save and import bookmarks but what about everything else? I look forward to anyone comments. Thanks

I downloaded the latest Firefox to my Linux and got this error message: W: Download is performed unsandboxed as root as file ......etc. There's more, but can you tell me what happened and if I need to worry? I haven't had any trouble using Firefox since the update. I've attached a screen shot of the whole message.

I appreciate any help.

Hello,

IS there any plan for TLS to go away with any upcoming release? Is there away to sign up for release notes to come to your inbox in advance?

thank you, Amanda

I just discovered this PPA thanks to OMG Ubuntu. But is this PPA official?

I'm trying to migrate my Firefox application and all of its associated data from my old computer (Windows 7) to my new computer (Windows 10). I copied my Mozilla folder from my old computer onto a flash drive. Then on my new computer, I executed the application from the flash drive, but it doesn't have my associated data from my old computer. What should I have done?

I updated to version 99.0.1 but it keeps on going back to 98.0.2. Things I had tried:

• Uninstall and reinstall Firefox
• Refresh in about:support
• Use a new profile

I think it is happening daily around the same time. Suddenly my pages in Firefox will stop loading. Then I need to close and reopen it. And then it will prompt me to start with a new profile because I am using an older version. On check, my Firefox had been reverted to version 98.0.2. Then I have to update and then only I can change back the profile.

I use Firefox as the browser for my email. Recently I have been unable to open or download pdf attachments (or any attachment) to emails. When I click on the attachment I get the message javascript:void(0).

I contacted the email company who said there was no problem at their end and that the problem was with Firefox and pop up blockers. I followed the advice in the attachment to unblock for my email account - but this did not solve the problem.

So I then tried Edge for my emails and I can open attachments in Edge.

So the problem is with Firefox.

Any advice please? Thanks

Is there an easy way to downgrade back from the beta channel to stable? The downgrade protection feature seems to be a major blocker of just installing the latest stable version. Noticing high RAM usage on Firefox 100 and crashes which is making it hard to use for a daily web browser.

Hello, since migrating from Chrome to Firefox, I have used the Import Wizard to successfully transfer over my bookmarks and history, but I just can't seem to get my logins/passwords over. The wizard finishes saying that it successfully imported saved logins and passwords, but nothing shows up in the password manager. I am running Windows 10 64bit and Firefox is up to date. Anybody have any suggestions?

Thanks

Every week, for work, I need to download at least one large video file from Microsoft OneDrive and then upload it to YouTube. (These are MP4s in the range of 200 - 800 MB.) For the last couple of months, maybe longer, the download keeps failing in Firefox. When I switch to Chrome, the same MP4 downloads with no problem.

Any idea what might be going on? Usually the file starts downloading just fine; I see the bar gradually filling up in the notification area, but then it suddenly stops and says "Failed." If I retry, the same thing just happens again.

I'm not using any kind of download manager (that I'm aware of), just relying on Firefox's default download behavior when I click on the "Download" link on the OneDrive web page (sample URL: https://olucdenver-my.sharepoint.com/personal/YADA_YADA/_layouts/15/onedrive.aspx?id=LONG_QUERY_STRING_HERE).

Thanks in advance for any help you can provide!

I've always used the "Always ask you where to save files" option when downloading. Recently (beginning of April 2022), files go directly to the Downloads folder. The "Always ask" option is still selected in Settings.

I've tried un-selecting and re-selecting, restarting Firefox, restarting my computer - basically every iteration of 'turn it off and on again' that I can think of.

I have just freshly installed a windows 7 on my computer which I have some old programs which won't run on windows 10. I am trying to download firefox with windows explorer which comes with windows 7. It seems I can not download anything. I try to download the firefox I get a message, The security certificate presented by this website has expired or is not yet valid. I downloaded once the firefox installer but in the middle of the installation I get a message OOPs something went wrong and it won't install. what is going on?

I've read all the articles here about importing my passwords and history, but the Import Wizard is ONLY giving me the option to import my bookmarks. Even if I can't get the browsing history I need to be able to migrate my (extensive) password list.

I've exported my Safari passwords as a .csv file, but there doesn't seem to be an option to import a .csv file.

The page here regarding it says the feature is 'disabled by default' but does not say it's unavailable and I can't find clear instructions for how to activate the feature so that I can import my passwords. Can anybody help?

Some how Yahoo jumped in and displayed a yahoo Home page with no way of deleting it. I tried installing Firfox..But it became stuck half way..what should I do to get back to Firefox ?

I lost my arrows on my scrollbar again after an update early last month. I tried adding lines to the gtk.css config files with no success unlike I've been successful doing in the past. It appears they are gone forever unless I can find another way to get them back. I noticed that the scrollbar arrows are gone on only Firefox and Thunderbird. As mentioned, this has happened in the past after some updates but in the past I was able to edit the gtk.css files in both gtk-2.0 and gtk-3.0 to get them back. Is there anything else I can try. I'm using the latest version of Ubuntu (Pop OS to be specific) and the arrows to the scrollbars disappeared around April 2nd for both Firefox and Thunderbird. I didn't notice any other applications where the arrows to the scrollbars disappeared. Is there something else I can try and a way to prevent this from happening in the future. This seems to be a common problem that happens every time there is an update.

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?

Hackers will be very happy now that Firefox automatically download their malware and backdoors.
