Diễn đàn hỗ trợ Firefox

I have several profiles. They all have the same Chrome folder contents, but only some of them have the "chrome_debugger_profile" folder.

I'm guessing I must have generated it along the way while tweaking the Chrome folder contents?

Hello! I have used Firefox on and off so I don't have a time frame of when this would have started exactly, but I have had some random completely black screens on both of my monitors dating back to at least 2-3 weeks ago that can only be fixed by powering down the entire PC. I've reinstalled my (NVIDIA) GPU drivers, rearranged display-port cables and just about anything before finally finding a fix, switching to edge. So far I've gone a week without black screening when with Firefox I'd get around 4 give or take a week (some days getting to 3 alone). I don't know what could cause it but I have noticed it only happens when first starting a video. Mostly YouTube but other video sites seem to have also caused it occasionally, I would just like to know what could be causing this, as I do prefer Firefox vastly and would like to switch back as soon as I can.

Will provide anything else as necessary!

I'm having issues with the cursor when opening a new tab and I've tried a few different fixes and none are really working.

When I open a new tab the cursor goes immediately to the start of the homepage URL which is not helpful as if I type it just retains the URL after what I've typing(See Image). I've tried playing around with about:config to get the cursor to populate into the google search bar on the browser home screen but, it doesn't work.

I've also tried setting the new tab page to blank but, then sometimes it doesn't search google even though it says it should and says URL unrecognised(see the other images).

Why is this happening, I just want to be able to not have to manually delete the URL to search using the search bar and this seems like really basic functionality to me.

Any ideas why I am seeing these strange rectangles on Google maps?

Confirmed not caused by an extension as I still see them in Private window and do not see them when using Brave.

They don't stay in the same geographical location when zooming in and out.

I have followed the steps in the "Prevent Firefox from starting automatically" article: https://support.mozilla.org/en-US/kb/firefox-starts-automatically-when-i-restart-window

But Firefox keeps starting automatically when I restart my computer. Attached is an image of how the settings are now.

What should I do? This is a bit annoying. I don't use Firefox as my main browser but I work as a customer success manager for an online platform and always need to do some tests on Firefox, but I don't want it to start automatically when I turn on my computer.

I'll for instructions.

Thank you

I got a notice that Firefox (and Thunderbird) were updated this morning. Took me an HOUR to find out how to make the miniscule font in my inbox larger. So.. suddenly, new problem.

When I click the Firefox icon to launch the browser, and reopen my tabs, It opens for a millisecond, then closes faster than I can try to read if there is an error. When I click it AGAIN, all my tabs are GONE and I have to search for them manually, which is a royal pain.

Why is this happening? How can I stop it from happening? This is annoying as hell.

When i go to google.com and enter search query the tab "hangs" for about 10 seconds before the next page starts to load Same issue on 2 separate machines (1 intel laptop, 1 amd pc) both on newly installed windows 11 pro

what i've tried: safe mode, disabling hardware acceleration, disabling antivirus (kaspersky, without any browser plugins or safe browsing) , but the issue persists

I use Firefox on a PC to access Facebook (website, not app). This week the Messenger/Chat feature stopped working. I click the icon and it opens but nothing appears in the box, it just hangs. There is an option to open in its own window, but that also is blank - no past messages, no contact names, no ability to start new message. When I log onto Facebook in Edge, Messenger works fine in Facebook.

I've tried everything I found on the internet for this issue - updated and refreshed Firefox, cleared history/cache/cookies/site data, uninstalled and reinstalled Messenger, refreshed Facebook to initial settings, used Firefox in troubleshooting mode, reset everything, turned off browser, turned off my computer, used shift key to reload tab - nothing has worked. There are some instructions about stuck cookies, but I didn't understand them so I didn't try that one thing. I've gone into every menu I can find to try to figure out this issue, which isn't the end of the world, but I would appreciate some other ideas for what is suddenly causing this. Because now I have to redo all of my settings and preferences and logins and the problem still isn't fixed.

Hi, I have been searching a way to change the Firefox new tab background image keeping its vanilla design. I found I could use a userContent.css file in this post from a few years ago: [https://support.mozilla.org/en-US/que.../1271362] I have followed the instructions step by step but it doesn't currently work.

I ran a loghttps://pastebin.com/jydVHHs0 of playing a youtube video mediaencoder? not sure if encoding issue or something else

The videos take a long time to play. I upgraded my system recently and was removing and reinstalling audio-related utilities with DNF.

From a security / QOL pov I'd like to disable an extension on some websites, and was wondering if there were any methods to do this?

I searched this question first through reddit and the support site and found similar questions with no updates asked between 4-6 years ago, wondering if there's been a method implemented yet or if it's still not possible.

Thanks!

I am unable to login to my Prescription provider's website (which I do every day). Problem started Sunday and still persists.

I am able to login using Chrome, so I know the website is working properly.

Help - I DO NOT want to use Chrome.

Hello!

I recently got a new computer with Windows 11 freshly installed. I downloaded Firefox, went to take a screenshot, and the usual shortcut of Ctrl + Shift + S does not work. I can right click and Take a Screenshot, and I can use other Ctrl + Shift shortcuts, like Ctrl + Shift + T to reopen closed tabs. The only one that doesn't work is screenshots. I can also put Screenshots in my top row Toolbar and use it, just not the keyboard shortcut.

I refreshed Firefox, uninstalled and reinstalled Firefox, as well as checked the about:config extensions.screenshots.disabled preference. It has been set to false, so I have set it to true and false again hoping it would "reset" it but nothing. Thank you!

Few days ago, some of our clients and few (not all) internal PC are get stucked on a PR_CONNECT_RESET_ERROR on our website. Only on 117 windows version (118 developer version and 119 nightly seems ok). We tried to repair firefox, it works on 95% but we can't ask our client to do this. It works on Chrome & Edge.

We running out of ideas : - we only accept TLS 1.2 / 1.3 - checking CSP - Both IIS and Apache are not working - Firewall are not blocking

Hi! I was wondering why nearly every single page these days opens to the message :

"400 Bad Request Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit. Apache Server at canvas.instructure.com Port 80"

Nearly every link I click on a website refuses to open! It has become impossible to do school work on this browser because I can't open any link on my school website, and nearly every website struggles to open except from google. I know the links work because I copy/paste them into Google Chrome and they open immediately. Truth be told I prefer Firefox and would much rather keep using this browser! I also can't find an update for Firefox so I believe my Browser is up to date (and I know my laptop is up to date and virus free). Is there a fix coming soon? Or a setting I can change to be able to open links? Classes start this week and I'm stuck!

Thanks for your help!

When a bookmark is made, there is no option anywhere to add tags using windows 11 - I had no problem with tagging bookmarks using Firefox in windows 10, but that option is not showing up for me in windows 11. I have refreshed Firefox with no success to try to correct this situation - thanks in advance for any help you may provide – del

I want to navigate on search results using the keyboard. I could use tab but it suggests all interactive elements such as news, images, books, videos, search settings and etc one by one. I want to press something and make active first result, then second. If such hotkeys are not provided, maybe there are any extensions with similar functionality?
