Firefox Community Forum

I had to uninstall Firefox. I briefly added then removed an extension called "atlas speed dial". Since then, I haven't been able to get a tab to open. I uninstalled and reinstalled Firefox. It recognized that Firefox was on my pc before when it reinstalled. I had some tabs open and organized. I tried to recover tabs. I tried just using a new window and opening new tabs. Finally I just uninstalled for good, unless someone can tell me how to fix this issue. I'm using two other browsers. Luckily, when I installed another browser I'm using, I decided to temporarily set the new one as my default. I've setup several shortcuts and organized my desktop since then. So all of the shortcuts work through the other browser. But, I'd really like to still be able to use Firefox and especially would like to restore my open tab organization.

When composing an email the cursor often disappears and has to be replaced in the correct position. It seems to only happen in Firefox. It usually happens after I hit the space bar or sometimes in the middle of a word.

I just tried Edge and the problem did not occur.

My email server is Yahoo.com.au

Have others reported this?

Why isn't there a setting to open closed tabs from the history menu in a new tab, rather than overwriting the current tab? This is incredibly frustrating as I just lost a lot of progress on a page that doesn't autosave when I tried to open a tab I had closed a day earlier with information I needed. Is there anyway to do this with config files or something?

Reposting until I get help from someone. Windows/desktop. On Google Chrome, any streaming website I used with autoplay enabled would KEEP full screen mode ON after changing episodes. It would automatically go to a new page with the following episode and remain full screen. Why doesn't Firefox have this feature?? I'm seriously considering going back to Google Chrome for this one small feature. Every time I had any streaming service playing with autoplay enabled, I didn't have to manually select the full screen option every time. I am having to stand up and manually click full screen function. Every. Single. Time. Somebody please help me if there's a way to active that function.

I reinstalled a new win11 and downloded fresh firefox. Sync is not working and I have no previous data to resume working. All tabs and logins are not showing in new firefox. Pls fix the issue.

I have a new laptop and am using Firefox as my browser. But when I'm on Facebook, go to chats it says that video chat isn't supported by this browser. Does Firefox not allow this? I've tried going to permissions to allow Facebook to access my camera and microphone, but unable to do so. How do I use the video chat feature in Facebook chats?

Desktop Computer. Still on Windows 10.

Not sure of category. This began when I launched the computer today. I opened Firefox and got the message "The bookmarks and history system will not be functional because ....."

When I started to shut down the computer (first mentioned step here) I saw there's a Window update. I selected Update and Restart. That went okay, but still don't have my Firefox bookmarks.

So I clicked on Learn more. I found the Firefox > Profiles folder. There are two folders, one from today - qkuxm6ws.default-release - 15...... 0196 with 94 items, and 7ghfiw 15.default, from Jan 5, 2021, with 3 items. I assume I should use the one with today's date.

BUT .... from this point, the information on this website was full of information - NOT step-by-step information telling me what to do with which files in this folder.

Also, I have McAfee as well as Windows Defender. I opened Windows Defender Firewall. State is On. Notification state: Notify me when Windows Defender Firewall blocks a new app. I've gotten no such messages.

Under allowed apps and features:

 "Firefox ... private not checked; public checked.."  
 "Firefox (C:\Program Files\Mozilla Firefox" - private is checked, public not checked.  

Can't make changes.

Under Overview window: Not checked is "Inbound connections that do not match a rule are blocked."

• • • • In the "Monitoring\Firewall folder" - Firefox (with path) is listed twice. Both entries have Private, Allow, NO Override -
      • Differences - the first has UDP; the second has TCP. Nothing under "Group."

My last bookmarks backup was Jan 2025. 😕 😟

I don't know where else to look or what to do. Please help. Kami

Mozillers,

I depend heavily in my environmental and other work on Firefox and am grateful for its ability to restore previous tabs when my laptop, not infrequently, stops working abruptly.

Now the much-used bookmarks have disappeared. A search site states promisingly:

"To restore Firefox bookmarks, use the built-in backup feature by going to Menu > Bookmarks > Manage Bookmarks > Import & Backup > Restore, then select a dated backup or a manual file (like a JSON backup) to bring back lost bookmarks..."

But my Firefox's Bookmarks drop-down menu has no Manage Bookmarks option. PLEASE, what must I do?

Elsewhere I managed to find this file which apparently contains recent bookmarks:

"C:\Users\User\AppData\Roaming\Mozilla\Firefox\Profiles\unk14jlv.default-release-1647366062305\bookmarkbackups\bookmarks-2025-12-26_95_4IdGtYxezJpwuH1UIiT1bRwe1K6bcGO8rv0mqa9rUWU=.jsonlz4"

But attempting to open it with Applications\firefox.exe (default) accomplishes nothing.

FOOL-proof instructions would be wonderful. Thank you.

I have a Firefox icon on my Windows11 desktop, Start, and one on the taskbar. If I click one either the Firefox icon on the desktop or Start I will get another icon on the task bar and I can do this over and over on my personal desktop getting many Firefox icons.

I just purchased a new Dell Windows11 desktop and have installed Firefox. I set it up just like my personal desktop and have icons on the desktop, Start, and taskbar but every time I click the Firefox desktop or Start icon I don't get a separate icon in the taskbar but they pile up behind the original Firefox on the taskbar. If the cursor hovers over the Firefox icon then I can see the multiple Firefox homepages that I generated.

I have searched for an answer to this problem but have been unsuccessful. I would really appreciate some thoughts on this issue. Firefox has been my one and only browser for many years and I love it 99% of the time, just not this one time. :-) Thank you in advance. Chuck Hall

If I don't use the custom adjustments in my Chrome css, seven buttons on that right side of the menubar are hidden, including the min-max close buttons.

This is problematic when I'm troubleshooting Firefox, and the css is disabled. If I want to close or take the browser out of max mode, I must move those buttons to the navbar, which has no such restriction accommodating those buttons, not to mention why is it necessary for that min-max close trio to monopolize 20% of the menubar. Waste of space. Inefficient.

I'm also curious why must that frame at the top of this sites pages remains persistent, and follows the user down the page, so that when you're composing, and accidentally (and all to often) touch one of those links, it get superimposed over the message, and you must move the cursor to the bottom of the page get rid of it. Not to mention, that frame shrinks the working area of the page about 30% vertically.

I mean, once you have already navigated to the destination page, and you're composing, how often/likely are you going to need to access that area?

I'm getting announcements of a virus threat that purports to come from Mozilla Firefox. Usually one or all three of the attached small windows that say: 1. "Viruses Found. Antivirus notification. via https+++d512ucanaffc739fe48g.cgm-defender.pro" With a Dismiss button. 2. Attention! Click here to secure your data!. via https+++d512ucanaffc739fe48g.cgm-defender.pro" With a Dismiss button. 3. "System Warning!. Click here to remove them! via https+++d512ucanaffc739fe48g.cgm-defender.pro" With a Dismiss button. I have run full scans and offline scans with MS Defender, but these warnings still appear. Is this legit? I suspect these are a virus of some sort. Either way, how do I deal with this?

For the very first time, today I got the following, "Gah. Your tab just crashed." and it now happens every time. What's up? Is this a Mozilla problem? Should I be moving on to a new browser? Help!
