Firefox Community Forum

I just downloaded Firefox and came to the page for importing data to Firefox, where it says " Import browser data" followed by a box containing "Microsoft Edge" in the next line, then

Select the data you’d like to import. Favorites Saved passwords Browsing history Form autofill data

then the prompt to Import

Is this a trick for Edge to import the data rather than Firefox or as it should be for Firefox to Import the data including that in Edge? As you might have guessed - I don't trust Edge or Microsoft one little bit.

I forgot my primary password and understand that resetting it will wipe all my passwords. Does this wipe the passwords locally or across all devices ? Will I able able to use my phone to sync my passwords back to my desktop after they are wiped from said desktop?

Hi all, I'm having an odd problem. For some time now, whenever I look at a list of programs on my computer, Firefox shows up twice. In the last week or so, a new problem has cropped up. When I click on a link in Thunderbird, Firefox opens, but it's like I'm in a totally new instance of Firefox. My browsing history doesn't exist, it will not remember that I have already told Firefox to always open Zoom when I click on a Zoom link, and if I'm streaming a radio station, that tab will be in a separate window rather than in a new tab as it was before. What's going on here?

For some reason my Firefox has started to become much slower when I view / watch anything in full screen, it doesn't matter from where. A Twitch stream in full screen? The Video Player becomes slow, even using the escape key to leave fullscreen takes a bit. Youtube video in fullscreen? Same thing happens. No matter what site is being used, if I go full screen on any video player, everything becomes suuuper laggy. I've tested other browsers and they don't seem to have that issue so it's not a hardware or connection issue.

After my pc has been on for a while, seemingly random duration, Im not able to open firefox anymore. For example if clicking on a link in discord, or if I close the browser and want to open it again. I've tried refreshing and reinstalling but that didn't help.

Hello everyone I just updated my operating system to refresh Win 11 and downloaded a fresh copy of Firefox signed in The problem I am having is when I switch to a theme it does not stay or show in the tabs Has anyone found a solution?

I had my startup page EXACTLY as I wished with two rows of most often used links to websites. While trying to find a solution to "page jumping" I use Help; "troubleshooting mode" and selected "Restart Firefox in Troubleshooting Mode". It did not solve the page jumping issue but did remove MY customized startup page and I do not how to get it back. I also used "Exit" and restarted Firefox but Firefox set my page to the default start page.

How do I get back to MY old startup page?

This is but one frustrating experience setting up MY computer to perform as I wish ... the computer culture has become "user unfriendly" .... what was once simple is now "too highly geek-ed".

Thanks in advance for your effort in solving yet another Firefox rabbit-hole problem.

You seriously need to remove the AUTOMATIC tab grouping, it's annoying as hell!

I know there's a workaround, but that's beside the point. You don't break into someones home in order to re-organize it, that's just bad practice all around.

working with miro site using firefox is terrible -

- too long downloading and redirecting - half of times strange errors occurs - https://disk.yandex.ru/i/PFQTbYdKGSKS0Q - no problem with chrome or edge - https://disk.yandex.ru/i/XBY6SIzk_gGBYw - just search all troubles - https://www.google.com/search?q=miro+is+not+working+firefox

Something happens to the images when I upload them to any service in the Mozilla browser. Instead of the image I see a strip. There are no such problems with any other browser. Attached is an illustration.

I'm having major problems with Firefox and was able to use it for a long time and I love the software to death. But it has given this problem that I have run into before which the only way I was able to fix it was a full wipe of my computer to factory settings. So with this I started to troubleshoot on what I could do and reinstall was the first and send commands to refresh the dns but I found to what seems to be a startup incomplete file in the Firefox software and it seems to create itself even when deleted. It could be this which is causing problems but all I know for certain that when I click on Firefox it won't open at all or startup. With the only evidence that it responded from task manager or a popup talking about wanting to refresh Firefox for 0.1 milliseconds

For no apparent reason, all Firefox 140.0.4 on Windows 10 crashed and when it was relaunched it did not restore any open tabs, reverting instead to the home page. All history is gone, no previously open tabs are windows appear in the history list. This computer has syncing enabled.

I used about: profiles on the Win 10 machine and it only shows the one that is currently in use. I copied the 2 files found in the along with places.sqlite into a temp directory. I did a search for index.dat and it is not found on the Win 10 computer.

Even worse: another computer running Win 11 that is syncing with the Win 10 machine is also now missing its history. Is there a way to recover from this?

Note: I am generating this from the Win 11 machine, not the problematic Win 10 machine.
