Firefox 技術支援討論區

I recently changed to Firefox from chrome and the focus on security and privacy was a much needed upgrade. However, every time I close my windows I'm logged out of all my accounts. I checked all the settings that would have that effect even escalating it to a clean install and unfortunately nothing works. After checking the support forums this setting seemed to be the one that fixed things, attached is a screenshot showing that its unchecked and that there is cookie data stored, so I'm really at a loss.

While on michaels.com I click on a product, it goes to the product then immediately the screen goes blank. It also happens when I do a search, multiple products show up, then the screen goes blank. I don't have that issues on other websites. What is going on and how do I solve this issue?

4 PM, November 7, 2023 EST. The "About" page of all YouTube channels suddenly disappeared, whatever the the login status. A compressed version will show up from a channel's home page when clicking on the site description from its Home page. Make things weirder, ~6:15 PM it WAS visible from the Tor browser but started acting the same. I have no ad blockers, or ANY extension installed on any apps, including Firefox/TOR browsers. Updates to both browsers were made prior to this behavior. It may be Google/YouTube's fault but it's becoming frustrating because I prefer Mozilla's browsers over Edge or Chrome.

Had to reinstall my pc over consistent error messages (thank you windows 10 for being the same pos system), and now all my bookmarks are gone, the bookmark backup folder is also empty, I have two years worth of personal and business related sites saved that will cripple me financially and mentally if I can't get them back.

Reaching out to Sync to try that, but looking for any kind of alternative fix here to recover the bookmarks.

Firefox is running x 8 in my task manager at the moment. Why does it keep multiplying and slowing down my computer? I am almost ready to uninstall Firefox. If I merely need to revert to an earlier version of Firefox, please let me know how to do that. Thank you. Shannon

my electronic health record is freezing using Firefox on 2 different computers in 2 different locations. Internet speed 45 mbps at 1 location and 900 mbps at another. Able to use it on chrome.

Recently have been unable to access the USPS Website from any of my Firefox Browsers. Firefox displays the following Message:

You do not have permission to access this page If you have found this page in error, please contact support Reference:10593116689666961403465577003670526342620034968299102359

Hello. I am currently trying to play a web game, but something is very annoying. The game doesn't implement pointer lock, so I have to play fullscreen for the movement to be continuous. Unfortunately, every time my mouse passes past the top of the screen, Firefox automatically unhides the titlebar and controls, and over all tries to escape fullscreen mode. This is very bad for the game, as the mouse movements are frantic and need a continuous mouse. How can I disable this behavior, so that Firefox keeps everything hidden in fullscreen until F11 is pressed?

Firefox not responding to general websites on the web (Ex: Amazon.com, etc.). I have several Mozilla-recommended security extensions that may be working against my firefox connecting to these general-in-nature websites.

I've created 22 themes and in all of them the drop down menus such as "downloads", "history", "extensions", and "application menu", all became white instead of dark like they used to be. I really don't want to go through the process of fixing and reuploading them, I'd apprecate you looking into this and hopefully fixing it with a simple update. Please fix this problem, thank you!

My current install of Firefox seems to be corrupted, because every time i try starting firefox, even in safe mode, it says "Could not load XPCOM". So my only option now is to reinstall, but i have some password and my search history and bookmarks and generall data to backup. So my question is how can i do this. Im on a Windows 10 22H2 Machine, and i am a pretty expirienced computer user.

hello

I downloaded Qwant browser some years ago out of curiosity then took this laptop offline. When I allowed this laptop back online, I noticed Qwant and disabled it, as I am accustomed to DuckDuckGo and no longer feeling curious, just want to get work done. Qwant is showing as disabled (under the Disabled heading, and greyed out).

However, when I use CTRL-N, the new browser window is Qwant, not Firefox, not DuckDuckGo.

I check that Firefox is my default browser and the laptop checks every boot-up that it is the default browser.

Can you help? I know there's a line of code somewhere but don't want to do more than I have -- endlessly search the settings, checking that there is nowhere that allows Qwant to load, let alone preferentially loads it.

Thank you! filterfeeder
