Hello world! Is there any documentation explaining if FireFox Sync is the best way to merge different computers and/or devices with different logins saved? And if yes, how to use it (which computer log in first, etc). Has anybody done it and can explain if in the process entries with the same URL were duplicated or if the newer login information overwrote the older one?

I have found this question ALL OVER the internet (phrased differently) and yet, NOT ONE OFFICIAL ANSWER or an unofficial one that actually answers the question. Many well intended volunteers suggest to export and import but then again, there's no information on how the process works. (Duplication or saving Account #1 Over Account #2 or newer over older, etc). How can we get a an official answer? I am sure the coders know how their tool works... why is it so hard to help so many people in need?

For users who have been using FireFox in different computers over the years, it's a VERY REAL problem. Right now, I have to switch between my different devices when searching for passwords as I'm unsure what the Sync would do.... We should not be sorry for having chosen FireFox over other browsers... Thank you.

Good evening. I'm seeking some help with an issue I'm having with Firefox.

As stated above, Firefox insta-crashes on startup. Hangs on opening in troubleshoot mode, then crashes after another 20 seconds and asks me to submit a report.

I believe this may have to do with the amount of tabs I had open when last using the browser. This morning I opened it up with about 7.8k tabs, and then closed it after adding another hundred. After trying to open the browser again, that's when the issues started. Until that point, the browser had been responsive and stable.

I've tried doing fresh installs of the browser and inserting the old data from the old profile, restoring to yesterday, and even trying without internet connection.

I have a Ryzen 5600X and 32GB of RAM, so I do not believe system resources are an issue.

Attached are some images. If any help could be provided, that'd be much appreciated.

The citibank site has not worked for a week or two. I get the following error:

Bad Request

Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit

Every day, I get multiple bookmarks added to my list that I do not want. They include, among others, things like Get Involved (there are at least dozens of these), About Firefox (again, Dozens), Help and Tutorials (many added). They clog my bookmarks on all things that access Firefox (work computer, home computer, IPhone, IPad) and the only way is to go in an delete them. I don't want nor do I need multiple versions of any of these. For that matter, I don't want even one of each added to my bookmarks. I've looked for help but unless you are a tech expert it's almost impossible to understand how to do that. I just want it to stop or I want to know how to stop it in the simplest way possible.

Hi, for a weeks I´m having error messages from firefox.

I have already updated windows and mozilla, restarted mozilla and my antivirus doesn´t detect any threat.

What can I do?

thanks!

I log into mydish.com, get into the website O K then I click onto my account and the screen will come up for a couple of seconds then the screen white and a complete blank and that is all I can get.

So how does one disable popup notifications like the one in the image?

The text just says cant show ads, disable vpn and/or adblock blah blah blah. It always pop ups when i load a page in that website

I've been running into this issue for several months now on Windows 10, currently using Firefox 1070.01 but has been occurring long before that. Only happens on my home PC, using identical accounts on my work PC is unaffected.

When opening a new window of Firefox, the home page and anything clicked within 5-20 seconds of the new window will load normally. After this brief window, all other loading will fail for an indeterminate amount of time, the bars will show filing but will not progress past 80% often resulting in connection error screens. Functionality will sometimes return, but closing and reopening Firefox is always a faster solution.

On this same PC, Edge and Chrome never fail to load pages, even directly alongside a failing Firefox load. This occurs 100% of the time on any webpage.

The same behavior can be observed after clearing my cache, removing all extensions and running the browser in safe mode. It has even continued after a fresh re-install of windows as well, but only ever on this PC and while connected to the internet via Ethernet.

I've replaced the Ethernet cable several times as well as swapping my motherboard, had my ISP swap my router and change the cabling that attaches my router. The issue does not persist over WiFi, but using WiFi only or swapping to it when needed is not an acceptable solution.

My ISP has been out here to test my connection on multiple occasions, no other online connectivity is effected as online games, online chat applications, as well as upload, download and ping monitors all return a stable connection with no interruptions. Only Firefox fails to load.

Would love to work with someone to get this solved. This issue has almost driven me back to Chrome

I am sending in a new laptop to HP(Windows 11) for service on the keyboard and want to physically remove the stored passwords setup and synced via my Firefox sign-in, but want to make sure they do not get removed or get unsynced to my account(so can still use on existing Firefox at home). I see where you may find the location of the directory which they are stored, so can you simply delete or clear that directory on the HP device before sending out for service? Will it re-sync when PC is back at home and not effect my other live devices I will be using?

cannot access one particular website. either error message 'timed out' OR 'problem loading page' appears. I have tried two browers and several search engines; removed bookmark/favorites and saved password for this site

I get this error when I try to use Firefox to get to this website "www.Fieldglass.net". I get variations when I use Edge and Chrome but it does not happen with Opera. I'd appreciate any help.

Thanks

I just started to run FF107, I don't understand why setting the compact option, do not really make things more dense. Same goes with all the menu.

Who needs all that spacing?

I have this

menupopup:not(.in-menulist) > menuitem, menupopup:not(.in-menulist) > menu {

 padding-block: 2px !important;

}

in the css file and still no "compactness"...

Thank you.

I am so fed up losing my pinned tabs.

I want a Firefox facility where I can have permanently pinned(locked tabs) and normal pinned tabs.

The permanent ones must not be able to be removed without myself physically clicking and removing them individually and are persistent when opening new browser instances, cannot be cleaned/removed by other cleaner programs are not saved in History.

Permanently pinned tabs should show a mark on the tab like a red padlock.

I use One Tab, but that has it's down side in that it clears my Tabs from the browser in to one single tab and then it is difficult to manage them, there are others and they all have their failings.

Please provide this locked tab facility.

I am trying to set the Firefox language to French in Linux system using the below code(Before running the above code, I am setting the system language to fr_FR): FirefoxOptions firefoxOptions = new FirefoxOptions(); firefoxOptions.setHeadless(isHeadless); FirefoxProfile firefoxProfile = new FirefoxProfile(); firefoxProfile.setPreference("intl.accept_languages", "fr-FR"); firefoxOptions.setProfile(firefoxProfile); driver = new FirefoxDriver(firefoxOptions);

But Firefox Accept-Languages header shows just "fr" as the code.

I need Firefox to pick up both the code and the region i.e. "fr-FR".

Please help.

Up until the last few months, I've been able to do a Yahoo image search, click on one of the images, and click through all the images one by one, JUST seeing the images, and NOT going to the website containing the image. Now, when I do the same search, and click on an image, it goes straight to the related website. I know it's Firefox related, because it works as it used to if I use another browser. I've cleared the cache and cookies, and Yahoo history and it still doesn't work. It was fine until a few weeks ago.

The process to change email address requires a verification be sent to old email. That account is not active so no verification can be received. How can I change my email from the dead ([edited] @cox.net) to the new email ([edited] @mailfence.com)?

I can't log into harryanddavid.com anymore because I get this error message. I have cleared browser history and cookies, and rebooted with no success.

Starting this morning, I get 'access denied' or 'unrecoverable error' on many sites. These are sites I frequently visit: retail, air travel, etc. Edge doesn't have this problem but I prefer not to use edge if I can help it. My Firefox is uptodate. So is my Windows 10.
