Firefox Support Forum

I have recently (today) installed a device (Mini Wireless USB adapter) on my desktop computer. I am now connected to my ISP modem wirelessly. I have been using Firefox as my browser for many years (ten?) and have not had a problem until today. When I attempt to go to a web site I get a notice that says: "Unable to find the proxy server. Firefox is configured to use a proxy server that can't be found. Check the proxy settings to sure they are correct. Check to make sure your computer has a working network connection. If your computer or network is protected by firewall or proxy make sure that Firefox is permitted to access the web."

I am able to get to any web site I choose when using another browser. I am also receiving my emails, and able to send emails. So I know the computer has a working network connection. When I have visited the Mozilla support site (having to use another browser) I see advice that shows opening the Settings page and getting to the Proxy settings. When I open my "Settings" page from the menu on the Firefox home page upper banner I do not see any option to get the Proxy settings. How do I access the Proxy settings page? Or how do I access the Firewall settings? Don't forget, I cannot open any web page from Firefox.

I wanted to make a lengthy post on a website today, but I accidentally hit CTRL + R twice which bypassed the "This page is asking you to confirm that you want to leave — information you’ve entered may not be saved." safety net. Is there a way to deliberately disable any and all refresh shortcuts and buttons when a safety net shows up, so my buttery fingers don't ruin my day to it's absolute maximum?

I want safety nets to be deliberately annoying.

Hi, Mozilla Relay/mask is connected to an old, defunct email address. How do I change that? The verifications are going to the old address that I can no longer access.

I just had to clean install Firefox after having problems. I've pretty much set it up how I want it, except when I quit Firefox and then re-open it all the tabs come back. Which I don't want. The box in the settings page for opening with previous session is unchecked. What else am I missing? I re-started my computer just in case that was an issue but the problem continues. Thanks

From: Dell XPS 13 (5 years old) on Windows 11. Up to date with The most recent version of Firefox which I believe is 120. Always stay up to date.

To: Dell XPS 13 (brand new as of this week), Windows 11 with all updates and Firefox most recent 120 again always up to date.

I have tried reading several articles on here and using different methods from multiple answers and threads and have failed to find a method which exports All of my bookmarks from my old computer to my new computer.

NOTE:

Would highly prefer a method that replaces all bookmarks and data on my new computer exactly with everything from my old computer!

I don't care about my bookmarks on my new computer because I don't really have any but I do care very much about my old ones. At one point when I was syncing them, The bookmarks on my new computer which didn't include The vast majority of them disappeared from both computers for a short time until I restored to a specific different date a few times and luckily have my bookmarks on my old laptop still.

I have tried exporting them as a JSON and as an HTML to put them on my new computer. I've read the HTML method puts them all in one place as opposed to replacing all of them. Obviously I would prefer the JSON method. However I have tried both with no success. I've also tried moving them into the documents folder both times as recommended. I've tried to restore to date on the new computer.

Transferring bookmarks individually would be way too time-consuming as I have a ton of different folders.

Someone please help me find a solution to do something which should be basic which is transfer all my bookmarks for my old computer to my new computer. I'm also logged into my Firefox same account on both computers and have tried syncing with no success as well. No matter how many times I do it. I repeated all of these processes many times with small variations.

Please someone help me get my bookmarks! Thank you for your time and help!

Best regards,

Nate

i had to rebuild my laptop computer and set up firefox on it, set up/turned on sync and the browser does NOT match the broswer srttings on the desktop where the sync comes from. bookmarked weblink icons only show up when a new tab is opened and vanish once a website is opened, icons for bookmarked weblinks on the bookmarks bar are generic wireframe globe-like-icons only, the custom firefox colour setup i struggled to create over the course of several weeks does not appear at all, nor does the dark theme. how then do i get this to -really- syc???

I use a MacBook Pro. I recently created a new profile for Firefox (for work purposes) and set it as the default profile, because I'm trying to get off Chrome entirely. The preexisting no-longer-default profile contained all my "personal" data - bookmarks, extensions, etc. Continued using both profiles for about a week with no issues. Last night my MacBook updated and when I reopened Firefox, the new default profile was fine, but when I went into about:profiles and launched the secondary profile in a new browser, it was completely empty - no history, no bookmarks, no extensions, nothing. That's at least a year's worth of data completely gone. I've looked through support articles and past folks' questions and am just completely lost as to how to restore it or what went wrong. If it's not possible to restore that data, how can I at least prevent this from happening again? I've very much lost trust in Firefox profiles because of this. Help please?

I just updated my Firefox browser. Now it doesn't work: "tab is crashed" - an endless chain, always again this.

You should try harder to release bugfree software ...

What about short-time help?

I can't download anything anymore. I get the "failed" message. I see in support questons that this has been going on for a long time even though there have been repeated "fixes" reported. I've used Firefox for a long time and really prefer it, but I'm having to change to Chrome to be able to complete my work.

I am suddenly getting pop-up windows from "Firefox Software Updater" as soon as I click the Firefox icon on my desktop (Windows 11) and laptop (Windows 10). The Firefox log in the pop-up is not in color, so I am immediately suspicious. The pop-up window did not happen on my laptop yesterday, but I got it on my desktop today, for the first time. I have answered "no" to the "do you want this app to make changes to this computer?". Is this legit from Mozilla? Usually, the browser updates automatically when I click the icon, saying I am now using the latest version of Firefox. Thank you.
