I set a theme with https://addons.mozilla.org/en-US/fire.../firefox-color/(Firefox Color), I tried changing the theme in settings to light or dark but neither work. I'm wondering if there are other ways to do so in Firefox that I could try. I'm on zen browser which is why it may not have worked.

I have just purchased an iMacAir 3, 2024. For the last 12+ years I have used an obviously much older iMac. I think I have successfully installed Firefox in my new laptop, but want also to tranfer all my passwords, bookmarks, etc. How do I do this?

I have set E:\ as my default download location. However in some cases Firefox does not respect my choice and silently downloads stuff to C:\Users\Name\Downloads. I really hate this. One example, a pdf downloaded from here https://scribd.vpdfs.com/. Please fix it. Thx.

For about 2 weeks now, the audio volume on youtube videos fluctuates up and down. The volume starts off low when a person starts to talk. For example, when the person in the video starts to talk, their voice volume is very low then within a second or two, the volume rises to normal as they talk. When they finish a sentence and start a new one (when there is a short pause in the audio) their voice is again at a very low volume, rising to normal in a second or two. This repeats as they speak throughout the entire video. This is not specific to any youtube video or youtube channel, it happens on all youtube videos. I have tried updating all audio drivers in Windows 11 - no improvement. I have tried rebooting the computer - no improvement Firefox is up to date, version 133.0 I have tried watching the same videos using Chrome and I do not have this problem.

I have been using Firefox as my default browser and Kaspersky Antivirus for many years. I was forced to switch to a different antivirus when the US denied Kaspersky from selling in the US because it was Russian. I decided to go with Bitdefender Plus. Since then every several times I open Firefox I receive the below notification from Bitdefender Plus I receive the following notification:

Can I get rid of this without losing my shortcuts and histories?

Subject: Clarification on Adding Username and Password to Proxy Settings

Dear Firefox Support Team,

I hope this message finds you well. I am reaching out to seek clarification regarding the configuration of proxy settings in Firefox. Specifically, I would like to understand how to include a username and password along with the IP and port address when configuring a proxy server.

Currently, I can enter the IP and port address in the network settings, but I am unsure how to include authentication details, such as a username and password, for proxies that require them. Is this feature natively supported in Firefox, and if so, could you please guide me through the steps to set it up?

Thank you for your assistance, and I look forward to your response.

Best regards, Emmanuel

I haven't received any emails since Dec 11 just before the last update. The tray on the bottom of the screen indicates that emails are down loading but none appear. Now I'm wondering it here is some kind of jam since there are now quite a few. I have cleared the recent history .

J'ai 2 boites mails dans mon PC Windows 11 recevant des messages sur 3 adresses mail (domdom@nordnet.fr /valerie.blomme@nordnet.fr / valerie@uzun.net) Une messagerie (domdom) n'étant plus lisible, j'ai réinstallé l'application Thunderbird mais cela a créé une nouvelle boite mail domdom. Voulant désinstaller cette nouvelle boite mail, j'ai finalement désinstaller les 2 anciennes et perdu l'ensemble de mes messages. L'assistance technique de mon serveur m'a permis de retrouver ma messagerie mais elle a rencontré un blocage et me conseille de vous contacter pour que la configuration des boites mails soit acceptée par le logiciel Thunderbird. Merci pour votre aide

I would like to ask you for supplementing system requirements for Firefox on Linux machines presented on pages like this, https://www.mozilla.org/en-US/firefox/133.0/system-requirements/ All the requirements shown for Firefox 133 on this page are satisfied in my Linux Fedora 20 with versions of the required libraries updated but Firefox cannot start GUI. As this concerns all Firefox versions newer than Firefox 95 that has the same requirements concerning Linux system and is functional in my system I have filed a bug report to https://bugzilla.mozilla.org/show_bug.cgi?id=1938497 Almost immediately I have seen the comment below my report, "Fedora 20 saw its end of life 114 months ago. Nobody cares about supporting Fedora 20 anymore." with status RESOLVED WONTFIX that means, "The problem described is a bug which will never be fixed." This means that some other requirements exist whence maybe a minimal number of Linux distribution should be noted as required for new Firefox versions to work. For "older" Linux users this would save them a lot of time.

I am lost. Not a computer savvy guy. I am very old guy. How do I download the latest version of Firefox. and what does it look like. That is what are its numerical designations. Thanks, Jim

I have used Thunderbird for years (now on 128.5.2esr (64-bit) for Mac). I have a very large number of folders, and I would like to have a default setting for columns in new folders I create. I am aware that you can change the column setting in the folder by clicking the "Select columns to display" button and selecting the ones you want, and that you can change the setting for all folders in an account by going to the "Apply columns to..." > "Folder and its children..." > select the account > select the account name at the top of the list. But I would rather not have to do that every time I create a new folder, but I can't find any other way to do it anywhere, including on another answer to a question in this forum, https://support.mozilla.org/en-US/questions/1426413.

Then I found two settings in the Config Editor... that seem like they might be where this can be done:

• mailnews.database.global.views.conversation.columns, whose settings in my case are:

{"selectCol":{"visible":false,"ordinal":"1"}, "threadCol":{"visible":true,"ordinal":"3"}, "flaggedCol":{"visible":true,"ordinal":"5"}, "attachmentCol":{"visible":false,"ordinal":"7"}, "subjectCol":{"visible":true,"ordinal":"15"}, "unreadButtonColHeader":{"visible":false,"ordinal":"9"}, "senderCol":{"visible":false,"ordinal":"17"}, "recipientCol":{"visible":false,"ordinal":"19"}, "correspondentCol":{"visible":true,"ordinal":"21"}, "junkStatusCol":{"visible":false,"ordinal":"11"}, "receivedCol":{"visible":false,"ordinal":"23"}, "dateCol":{"visible":true,"ordinal":"25"}, "statusCol":{"visible":false,"ordinal":"27"}, "sizeCol":{"visible":false,"ordinal":"29"}, "tagsCol":{"visible":false,"ordinal":"31"}, "accountCol":{"visible":false,"ordinal":"33"}, "priorityCol":{"visible":false,"ordinal":"35"}, "unreadCol":{"visible":false,"ordinal":"37"}, "totalCol":{"visible":false,"ordinal":"39"}, "locationCol":{"visible":true,"ordinal":"41"}, "idCol":{"visible":false,"ordinal":"43"}, "deleteCol":{"visible":false,"ordinal":"13"}, "xnoteCol":{"visible":false,"ordinal":"1"}}

and

• mailnews.database.global.views.global.columns, whose settings in my case are:

{"selectCol":{"visible":false,"ordinal":0}, "threadCol":{"visible":true,"ordinal":0}, "flaggedCol":{"visible":true,"ordinal":0}, "attachmentCol":{"visible":false,"ordinal":0}, "subjectCol":{"visible":true,"ordinal":0}, "unreadButtonColHeader":{"visible":false,"ordinal":0}, "senderCol":{"visible":true,"ordinal":0}, "recipientCol":{"visible":true,"ordinal":0}, "correspondentCol":{"visible":false,"ordinal":0}, "junkStatusCol":{"visible":false,"ordinal":0}, "dateCol":{"visible":true,"ordinal":0}, "receivedCol":{"visible":false,"ordinal":0}, "statusCol":{"visible":false,"ordinal":0}, "sizeCol":{"visible":false,"ordinal":0}, "tagsCol":{"visible":false,"ordinal":0}, "accountCol":{"visible":false,"ordinal":0}, "priorityCol":{"visible":false,"ordinal":0}, "unreadCol":{"visible":false,"ordinal":0}, "totalCol":{"visible":false,"ordinal":0}, "locationCol":{"visible":true,"ordinal":0}, "idCol":{"visible":false,"ordinal":0}, "deleteCol":{"visible":false,"ordinal":0}}

The first one matches the columns I see in a newly created folder better, having the "xnoteCol" entry, but my new folders also have several columns related to my CardBook extension at the bottom of the list. Moreover, the settings' arguments don't make sense in terms of what I see. For example, I see the Thread column, whose settings – ("threadCol":{"visible":true,"ordinal":"3"} – make sense since "visible" is set to "true", but I also see the Attachments column, whose settings – "attachmentCol":{"visible":false,"ordinal":"7"} – *don't* make sense because "visible" is set to "false". Similar no-sense settings occur in the second setting.

So there *is* a way to change the default column settings in Config Editor..., which makes a whole lot of sense, but the way the settings are set in these two settings, which apparently are not the ones that fully determine my default settings given the CardBook-related columns that I see, do *not* seem to make sense.

The "Folder and its children..." approach works, but it makes it harder than it should be, and it seems like there must be a way to change the defaults in Config Editor.... If there is, please tell me how.

Thanks for any help you can give...
