I had something like 7 windows open 10 minutes ago (yes I am a tab hoarder). I was trying to run a game that used a lot of RAM, so I decided that I would close ALL of my firefox tabs in hope that the game would run smoother with the 5gb that Firefox was using. I didn't think anything of losing the tabs because I had accidentally closed windows in the past using the big red 'x', and an easy ctrl + shift + t always restored the entire window no problem. When I tried to open firefox again within the next 5 minutes, only 3 of the windows restored themselves, I assume using the general > startup > open previous windows and tabs setting. Using Ctrl + Shift + T did nothing to restore them. Please help, as the windows that did reopen were the ones that I cared the least about.

First, I am not tech savvy. I deleted my browsing history but, I see a new list of recently searched places. It is listed as Firefox suggests: then identifies my desktop and recently searched websites that are no longer needed. I want to be able to delete these tabs, or whatever they are called.

Dear Mozilla

I wrote to you earlier today about a problem i am having with themes.I change themes quite frequently and have a lot of them on my list. After opening and closing the browser once or twice the list of themes no longer shows what each theme looks like. I reset Firefox and the image of each theme reappears. It's quite tedious as i said to have to do this once or twice a day. Is this problem occurring because i have too many themes on the list?. I have turned off all other extensions and the same problem keeps happening. I don't know what to do.

After the latest update I could not access any websites

I thought it was the VPN I just installed, so I uninstalled it, but that still did not fix the problem.

I did 3 system restores and still it did not fix the problem.

My browser had changed and I spent hours trying to sort this problem out.

I uninstalled Firefox and then re-installed but still had problems connecting to the web.

Then when I was going to uninstall Firefox again with a special program, it gave two choices, uninstall or repair. I selected repair and sure enough I could access the web

All my browser extensions on tool bar had disappeared

The tool bar was full of junk, so I used Customised Toobar and finally fixed the problem.

I have disabled auto updates

Thank you Firefox for the inconvenience you caused , but I forgive you, because I consider you provide the best browser to use for access to web

firefox monitor does not allow me to sign in using dashlane password manager. Every other website responds by either filling in the name and password, or asking if I want to use Dashlane data. Please help. thanks

Hi,

I have been trying to use the extension "Sidebery" to replace "Tree Style Tab"

If my tabs are nested, bookmarking the tab tree will give me nested folder structure in firefox's bookmark.

If I right click on the top level folder in the bookmark, select "open all in tabs", firefox will only open those bookmarks in the 1st level folder, but won't open those bookmarks in the nested folders.

I wonder is there a way to do it? That is, open all bookmarks in a folder with those in the nested folder, all at once?

Best, Jake

Some websites like youtube, twitter, reddit and maybe many more don't properly load. On youtube videos freeze after a couple of minutes, I don't have any of these other issues on other browsers like Chrome

I've been attempting to use FIDO2 w/ PIN support to log into Okta. This occurs with a pre-registered security key (Yubikey 5C NFC on most recent firmware) that has a PIN already configured. This key works on all other browsers and devices without trouble. Firefox is unresponsive to Yubikey interaction after the notice "Touch your security key to continue with <company>.okta.com" and will eventually time out if I do not cancel.

On the other hand, I can register a new security key on Okta through Firefox on this device. When I go through the registration workflow, Firefox is responsive to all interactions, allowing me to enter my PIN and complete registration.

I have been able to replicate this issue on other computers and with a different user / security key.

I've had this problem off and on for the past month or so. I've read through every related question and tried all solutions presented without any luck.

When I press the star next to the address bar it turns blue, but no bookmark is actually created. When I press the star again it remains blue. No dialogue box shows up. When I right click on the open tab I get a grayed out dialogue box. I *can* bookmark several tabs at once, but that's it.

I've tried changing the preferences in aboug:config to true/false and back again. I've renamed/deleted the favicons folders. I've restarted both firefox and my computer. I'm running in safe mode with no extensions. This happend once about a month ago and resolved itself. Now it's back and doesn't seem to be going away.

PLEASE help. I've tried all the solutions mentioned here before but nothing is helping. :(

I have tried every solution that is on support to get rid of robot head with red eyes . Have went in to about config , changed dev tool remote to false and it gets turned back on everytime .Have uninstalled firefox ,nothing works . I would love to keep the browser but if this cant be fixed I have no choice but to uninstall for good.

Every time I log on a site where I have previously searched something in their search bar, whatever I searched either gets auto-filled (even if I want to search something else) or appears in the bottom of the search bar. They disappear if I clear all my search history but then I have to re-log into every site on my browser.

How can I delete those suggestions/make them not appear anymore without loging out? I have tried checking the autofill settings but everything is password related.

Hi Folks. My web browser shows "United Kingdom " near bottom left hand corner. I live in Christchurch South Island of New Zealand. My searches seem to direct me to UK sites ? I recently upgraded fire fox. How do I change this setting. back to NZ or is there some other problem Thanks Peter Royle

I have four active Firefox windows, each with quite a few tabs. I have been closing and re-opening Firefox with no issue until today. Earlier this week I updated my Mac OS to Ventura 13.5, and Firefox was still operating normally after the installation (closing and re-opening with all windows and tabs intact).

Today however, when I restarted Firefox, no windows opened automatically. I closed and restarted a few times, and finally one window opened intact; however the other three windows (still dispalyed on the "Windows" menu) refuse to open. When I look at my Firefox app on my iPhone, it also shows all the tabs intact.

What can I do to get these to open? I am running Firefox version 115.0.3.

Firefox .pdf viewer has documents shifted too far to the left. there is no way to center them with the tool even reducing the doc. from 100% to say 80%, they remain too far to the left. without any left side margin, any printed doc. that must be 3 hole punched for a LL binder, has data punch through it. this doesn't happen with any docs. printed directly through hotmail. they are centered correctly but any .pdf, even downloaded say through Adobe Reader but opened with Firefox will have the same problem Why? thank you, Michael
