Firefox Support Forum

Each morning, when I first cold boot my computer, the moment I open my Firefox browser, I receive numerous (10+) identical error messages from Bitdefender:

Suspicious connection blocked: Feature: Online Threat Prevention

firefox.exe attempted to establish a connection relying on an unmatching security certificate to content-signature-2.cdn.mozilla.net. We blocked the connection to keep your data safe since the used certificate was issued for a different web address than the targeted one.

Question: Is this ACTUALLY coming from Firefox? If so, please match your security certificates! If that's impossible due to a technical issue, then please email me your confirmation so that I can add an exception to Bitdefender.

Question: If it's not coming from Firefox, please email me, letting me know what additional system information you require so that we can get to the bottom of who/what is masquerading as Firefox while attempting to establish an unauthorized Internet connection from my computer.

HP Envy laptop, Windows 10 OS, latest update.

This has been occurring for several months.

Thank you for your time.

Hello,

I'd like to decrease the font size and change the font type in the pull down bookmarks menus. Is there a way to do that? There is no effect after tried Fonts and Colors under Preferences - Language & Appearance. Thanks.

I want to completely disable the 'restore previous session' option.

I want to start a new session with my preset home pages 100% of the time.

Having Firefox display a page 'unable to restore previous session' with the options of 'display previous' pages and 'start new session' is inconvenient at best. I do not want to see that page, I just want Firefox to automatically start a new session every time I open it.

In the Tools menu settings tab, the 'Restore previous session' checkbox is not checked.

Logging on to my bank web site is no longer possible with Firefox. It used to be, so I assume the bank's computer security protocols have changed. However, I can log on with the Microsoft Explorer browser - works every time! Moreover, in the past, when I could still log on with Firefox, I could never "register my device" for the bank site; it always gave me an error message. With the Explorer browser, I can register my device, with no error messages. I have tried all the suggestions in the Firefox help section: erased remembered history, erased all history, erased all cookies, erased cookie profile files. Nothing works.

According to FAQ of Caching Mechanism (mozilla.org), it is by design to cache “documents specifically marked for "not caching" through-- "Pragma: no-cache" or a "Cache-control:" directive specified as an HTTP response header” in memory to improve performance. So, it is possible for you to view sensitive information from the Firefox memory cache after you log out an web application and keep Firefox open.

I am constantly unable to access websites. My data seems to clog up. I'm in my 70's and have no patience or training for sifting though numerous fixes and possible solutions. I've done my best with no improvement. My husband is having the same issues on his computer. All my previous efforts erase my sign ins and require me to constantly enter new sign in information for my common websites. I can use Safari and Chrome without these issues so unless I get some form of personalized help that doesn't require a great deal of technological skill, I'm leaving this browser greatly disappointed in the lack of support.

Having issues that started this morning once I start up the Firefox browser. The browser font for all numbers and letter are extremely blurry. Never has happened before, tried to look for a trouble shoot but cannot find anything to help anywhere.

Go to this page... https://electronics.howstuffworks.com/prepaid-cell-phones.htm

Click on any of the links embedded in the text, such as _United Press International, TCM Net, Wireless Guide_. No response.…

EDGE and Chrome have no issue with these links.

Until recently, when I started typing in the address bar, FF was offering suggestions that were clearly based on addresses I had gone to in the past and seemed remarkably prescient about where I wanted to go. For example, if I typed the name of my hosting service, Seanet, one of the top 2 or 3 choices would be Seanet's login page.

Now, if I type "sean" for example, I get a bunch of irrelevant stuff ("sean connery") and about 10 lines down, it says "firefox suggests" and one of those is the login page. I ran into an article talking about how to change settings under privacy/address bar, but those don't affect this behavior. They change what might be the source of suggestions, and I limited it to browsing history, and that didn't help at all.

Maybe this is something that can't be fixed, but things were easier when FF listed very near the top the actual addresses I went to. Not all have deteriorated, e.g. (to reveal stuff about me) typing "x" gets xkcd.com as the first suggestion, and typing "e" gets explainxkcd.com as the first (sorry, sometimes I don't get the computer references and need an explanation).

Any help would be appreciated.

Hello, A folder titled 'Old Firefox Data' keeps appearing on my desktop. I googled when it orginally happened and after reading the help articles decided deleting it was alright. I had refreshed Firefox and wasn't concerned about deleting anything important. Now everytime I restart my computer a new folder with the same name appears. This wasn't happening before and doesn't seem normal. Thanks!

I just formated my laptop, when was asked to give a name i just ended up writing the same one as the last one, then i logged in in Sync and all my data was lost, passwords, bookmarks, history, everything. I'm pretty sure it was because the laptop had the same name and was registered as the same device in Sync at the time of formatting. In my smartphone the data was gone too. Is there anything i can do? or it all lost?

Hi, my mac broke, All my passwords were saved in firefox account. As everything happen so suddenly, I did not remebered my firefox account password and changed it. Now I can't find all my saved passwords even I logged in. I did this fiew hours ago. Is there any possibility to restore them? :( I just sit and cry.

There are extensions that I am not using 99% of the time or use them at one website.

There a two options:

• Make UX more friendly: add button to list an extensions with checklist to disable OR add "Disable extension" option inside menu between "Manage extension" and "Remove extension" (by right mouse click at extension icon at Toolbar.
• Be cool if Mozilla Team will develop mechanism to switch between extension modes. As example I create my default exts mode (ublock, firefox notes, multi-account containers), but also time by time I save webpages by SingleFile extension, also I use proxy extensions so I create list for it. Lists may be as additional (default + proxy) as independent from scratch (proxy only).

Why? Privacy by isolation processes in the browser.

hi, when i right click and see the contextual menu, i no longer see great options and i miss them. (eg, scan with virus total, or google reverse image lookup)

how can i add such items to my contextual menu in firefox browser? thanks!

Hello, Firefox on Mac doesn't sync tabs because of the following problem:

Sync.Synchronizer DEBUG Updating enabled engines failed: Error: CreditCards is not initialized. Please restart if you flip the pref manually.(resource://autofill/FormAutofillStorageBase.jsm:2018:21) JS Stack trace: get@FormAutofillStorageBase.jsm:2018:21

Do you have an idea what's wrong here? FYI: I use a custom user.js file.

I would like to create a FireFox shortcut in the Windows 10 Startup folder so FireFox loads automatically at boot time, in a minimized Window (or better yet, the system tray). There does not appear to be any way to make this happen. I have searched pretty extensively. If there is a way, I'd like to hear about it. If there isn't, I would like to suggest it as a feature for future development.
