Firefox Support Forum

After rebooting a Windows 10 computer, and starting Firefox, two Firefox Windows open. The second one opens Yahoo on it's Tab with no other Tabs open. Before booting, there was only one Firefox window open. This has happened before in the past.

Could this be fixed.

I have also reported several times that at times, Bookmark folders are found missing but found in strange places where I did NOT move them. I have been told that this could be possibly caused because of my very large Bookmark file. It would be very nice if this was resolved. I have reported this at bugzilla.mozilla.org.

Yesterday firefox private window comes up on my browser...I do NOT want that, how to get rid of it?? My desktop is set up with menus for quick reference; I cannot get past this private window

As per subject. When i click a Mailto link in a webpage, eMClient opens OK, but message window does not. Seems to be a Firefox problem because it works fine in Chrome. I've checked the Firefox and Windows (10) settings; all seems as it should be. Any suggestions? Thanks.

I often use Ctrl+Number to jump to a fixed tab, whereas on Linux the shortcut is Alt+Number, which causes some inconveniences. Is it possible to make Firefox use Ctrl+Number to switch tabs on Linux?

I'm trying to load a jsonlz4 backup of 88.4 mb with 1 146 851 items. When creating a new places.sqlite, the majority of the bookmarks inside Other Bookmarks don't have a location url. Like this:

Name_____________| Location

Normal bookmark | site.com My problem_______|

I tried using https://www.jeffersonscher.com/ffu/bookbackreader.html to convert it into html and json. Importing the html into firefox puts everything into the Bookmarks Menu and everything is missing their location url. Opening the html in writer I see that every bookmark does have its location url but as hyperlinks on the names. Restoring the json, 1 time after not clicking the Check/Repair JSON button and another time after clicking it, gives me all the bookmarks in their correct place but the majority are still missing their location urls.

I also tried creating another places.sqlite with my jsonlz4 backup and exporting as html and json through the bookmarks Library. Importing them, separately, into new firefox profiles just gives me the bookmarks that weren't missing links.

Also tried creating a places.sqlite in windows but it stopped before the Other Bookmarks folder, I guess.

I don't know if its relevant but between restarts and shutdows I always have 18 kmozillahelper processes before even starting firefox. I don't know since when they haven been there or if they have increased.

Any ideas on how to restore correcly my bookmarks?

At some point after a Firefox and/or Windows update, Firefox started to stall after working for a while. When I open Firefox, I start surfing using multiple tabs, using bookmarks, typing URLs, or clicking on web links and then suddenly, the little dot in the current tab where I am trying to access another link, starts moving right and left indefinitely, apparently waiting or unable to access the desired page. After that I type well-known URLs (such as google.com) that I know "always" work, and the same thing happens. From then on Firefox cannot access any URL I throw at it (no error messages or warning of any kind) until I close Firefox and reopen. Once I reopen, the cycle repeats: it works for a while until it doesn't. I have cleared all cookies and caches, I have erased or disabled all extensions, but the problems persists. Any advise? Thank you.

The first time i enter fullscreen for the on the current monitor, the window is not filled completely. It fixes itself if i exit fullscreen and enter it again.

I did not observe this behaviour in 124.0

this also happened like 1 year ago. i made a comment about this in a bugzilla thread right here: https://bugzilla.mozilla.org/show_bug.cgi?id=1763981#c119

The fix mentioned in that thread is applied for me.

It does not fix it.

I can't use Firefox on my Mac with the Reddit.com web site because letters vanish. I started to type "Mac" but aafter the "M" nothing appeared and I got the message "Server Error."

I just had a similar thing happen on the InternetArchive (archive.org).

Chrome and Safari work perfectly.

I've updated Firefox several times with this problem.

My internet has 750mb of bandwidth. Updated 64bit Firefox can only provide 320mb. I installed Chrome and the internet went to 800mb. What could be slowing down internet speed in Firefox? I restored Firefox, restarting everything. I did the same with Windows 10. I restored it to an earlier date. It didn't improve anything. What to do ?

Version 126.0 (64 bit) Mozilla Firefox for Linux Mint mint-001 - 1.0

I use a wireless keyboard and mouse via a USB connector. History - I have had to reboot to clear the mouse interface error when it occurs for many months. I've had a open issue in the linux mint forums as I thought it may be a driver issue. Things worked tolerable until 5-29-2024 as my wireless mouse has been deactivated. I opened a second window(tab) in a new window and my wireless mouse permanently no longer works. It was quite startling. The wireless keyboard is fine. A wired USB mouse works. My HP laptop mousepad works. However, once the error occurs mouse clicks are no longer responded to and the active area remains the partial window where the mouse was last active. Currently the mouse cursor does not respond to movement inputs from the wireless mouse, so seriously worse.

Have the mouse settings or driver have been tampered with?

Hi, I would like to remove the hints that appear below the sign-in box for my email account (yahoo). I want to be able to type in my email address each time without being prompted by a hint address (windows 11/firefox browser). Please help me eliminate/delete the addresses that auto-populate the hints email addresses. Thank you.

ps: please note that I do not have an in-depth understanding of computers or computer development language (mostly computer illiterate). I cannot write or change code.

I always had one version of Firefox installed. I regularly update the software via Help >> About Still, after every update, I am getting multiple versions of Firefox listed at [Settings/Installed Apps] and [Control Panel/Uninstall or remove apps] on my Win11 23H2 22631.3593 (screenshot attached).

In order to get rid of outdated items from the list, I need to reinstall Firefox completely, but the same thing is happening with every update of Firefox.

Is there a way to resolve this and why is this happening?

Hello! I've been noticing for several versions of Firefox that the response times reported in the “Network” tab of the developer console are wrong. In Chrome it shows the true value, which are a few ms, while in Firefox they show that it takes several seconds!!!! I attach the images of the problem.

Is it a bug, or a configuration problem itself? Thanks in advance

When I start FireFox most times the browser comes up then stops and restarts with a pink color on the web address line. I have tried making changes in settings but I can not find a setting for this. If I restart Firefox right after this happens, I cn search or browse without the Pink address line. Why is this happening. It would be nice if FireFox technicians would respond to help questions instead of sending questions to a forem...

Firefox spawn too many child processess, with cause the browser to freeze.

Proposed solution:

Reduce to absolute minimum the spawn child processess. The value should be set according to the device performance and additionally show allow the user to set manually the limits.

Example: 1 (maximal 3) child process per tab/window

Please help me to understand why I keep getting the 'Gah! Your tab just crashed' message. This only started a couple of weeks ago, but is extremely annoying and makes me doubt the integrity of Firefox. The problem can be circumvented (at least for a while) by closing and re-opening Firefox, but I'd prefer not to have to keep doing this.

I restarted my Windows 11 laptop and got error message about user profile. Restarted again and looks like it was corrupted so deleted my my user profile and Firefox config and bookmarks are gone!

Still have all the files just a new user profile and the old one is gone?

Any help how to get Firefox bookmarks back would be much appreciated

for example: discord.com => discord.com/app

Is there any better way than adding a bookmark for it?
