Форум поддержки Firefox

I want to use the Advanced Preferences (about:config) to select 'Manual proxy configuration' setting. I have been able to set the HTTP Proxy and associated port but I am unable to find the setting in Advanced Preferences that will select Manual proxy configuration. Could someone please help. Thanks

Firefox removes the exceptions after every update and they have to be manually re-added. This is a very frustrating user experience. Can you please help me identify if this is an issue with Firefox that can be updated or is it an issue with some setting I have setup.

Exceptions that get reset - Cookies and Site Data, Pop-ups, Add-ons, etc.

Permissions that get reset - All of them Location, Camera, Microphone, etc.

• Side note, the Troubleshooting Information section below has a link to share data, that link does not open in a new window. It opened in this same window, erasing all the content I had typed up the first time.

Even after numerous Uninstalls and a Reinstalls I keep getting this error notice when trying to open Firefox...

The application was unable to start correctly (0xc0000022)

I've received my new PC and will be migrating from my old PC (Windows 10) to the new PC with Windows 11.

I use local folders in Thunderbird to keep various projects separate and more easy to manage. I have copied the current Thunderbird profile on to an external hard disk, I have found the location of the local folders and they reflect the structure in the Thunderbird screen I see. Thunderbird has been unstable for a few weeks so I would prefer a clean install but don't want to lose a lot of content that I still need.

1. Is there a way to copy over just the local folders, eg export them, rather than the whole profile? I deliberately haven't cleaned the server recently so that I can get back emails that still are in the in_tray but once they are in local folders they disappear from the Yahoo server. 2. Is there anything else significant I should be aware of before migrating? There is a backup on Mozilla but I prefer a clean install.

Thanks in advance,

Anne

Hi there,

I'm curious if it's possible to configure Firefox on your own to make it a portable browser. Specifically, I want to disable data encryption and machine ID checks. I know that some chromium-based browsers allow you to do this through specific switches that turn these features off, resulting in a fully portable browser. While I'm aware of third-party applications that offer ready-made solutions, I prefer not to use them for security reasons. I'd like to prepare my own version of Firefox.

I understand some may have security concerns, but I know what I'm doing. The files will be stored on an AES256 encrypted drive. Could anyone share insights or guides on how to achieve this with Firefox? Thanks a lot

PS.For those who might suggest using synchronization, I assume that, similar to Chromium, Firefox can't sync all plugin settings, and for me, plugins are essential—without them, it's not really a browser.

Many questions and answers I see regarding the sync function. I would like to know the depth of what Firefox does. I have multiple PC's and an Android. What is the depth of sync for extensions? Is it possible to have mirror images of the entire Firefox setup duplicated? It would be spectacular to move from one PC to the other and find that Firefox has the exact same setup.

I reinstalled the Visual C++ and Firefox loaded when i ran the Firefox repair but totally locked up. Unable to get to settings or any website and will not run after closing it.

For some time now, e-mails have been arriving with a delay, e.g. from April 15, they arrived only on April 18. The mail is on the home.pl server pinned via IMAP.

I am watching a Twitch video on Firefox. When I open a new Firefox tab and drag it to another monitor, the Twitch video skips forwards about a minute.

I also occasionally notice skips or pauses when I switch from one tab in the same window back to the Twitch playing tab.

Is there any way I could fix these problems?
