I-Firefox Community Forum

Please help, can anyone answer me. I am on Windows 11. Asus laptop PC. 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. This needs to change PLEASE.

Today IMDb Pro and Linked In pages will not load on my desktop.

I have cleared the cache both using Firefox and CCleaner. Nothing helps.

Linked In has a loading indicator that never completes.

IMDb Pro has a blank feed for the home page. I can search some pages and get data. Many pages will not load.

I've been a user of Firefox since day one, now to me the browser is utter garbage, always fighting to do something that was so simple in the early days of Firefox. Wheres that bring the internet back simple browser gone ???

Every update breaks something its like you have a bunch of kids sitting in a play pen hoping the next release will be wow waw great brill but no its turned to garbage, utter garbage, did you sell out to another company or something ??

I was hoping to be saved from Chrome but you just cant beat an old dog forever.

RIP Firefox Im done with it !!!!!

I actually signed up for an account for this, thats how strongly i feel ive been let down.

I have enabled the option to open the previous windows and tabs. I had one window that I always closed last as it had a lot of groups that are important for my work, so it used to open every time I started Firefox. Sometimes, even if I closed the window by mistake without closing other windows, I was able to get it back by pressing ctrl+shift+n.

But yesterday, I might have closed it by mistake and when I pressed ctrl+shift+n , it didn't come back. I wasn't able to access my window and now it's all gone. I don't see anything in recently closed windows in history.

I need those tabs back as they are very important for my work. they were a lot of tabs. I had many groups but now all are gone. I tried by using the previous.jsonlz4 in the sessionstore-backup by renaming it in the default-release profile as sesstionstore.jsonlz4 but still wasn't able to access my window.

I didn't clear my history as the tabs opened in the window still show up in the history.

Kindly help as soon as possible

Dear Mozilla Support,

My name is Sizhe Xiong. Today when I launched Firefox on my Windows computer, the browser suddenly required me to select or create a new profile before continuing. I had no option to skip this step, so I created a new one.

After that, Firefox asked me to log in or register a Mozilla account. I used the same Gmail address that I’ve always used for Firefox Sync, but it seems that a new account was automatically created, and all my previous data — including bookmarks, history, saved passwords, and extensions — disappeared.

When I checked my local Profiles folder under C:\Users\<username>\AppData\Roaming\Mozilla\Firefox\Profiles, I found several new folders created around the same time, but none of them contain my old data (all places.sqlite files are around 5120 KB).

These bookmarks and passwords are very important to me. Could you please help check if it’s possible to recover my old Firefox data, or if my previous Sync data can still be linked to my Mozilla account (using the same Gmail address)?

Thank you very much for your help.

Best regards, Sizhe Xiong

I am incredibly frustrated by the continuing problem of all my Bookmarks disappearing with the usual "The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. Some security software can cause this problem." This issue has been going on since NOVEMBER!!! I usually manage to get my Bookmarks back by closing all txt files that I need to keep open, store them in a new folder on my laptop, and then restart my laptop. This time, it didn't work.

Can anyone steer me to a permanent solution to this problem?

Thanks, in advance, for any help offered.

I own three laptops and they are in my Firefox account and synced. I have several bookmarks for site I frequently visit. On two laptops, based on my settings, when I tap a bookmark it opens up in its own tab. This is how I want these to function. For some reason, my third laptop does not behave in this manner. The new bookmark opens up on the tab I am currently in. It gets bumped and the new bookmark opens. This is exactly how I do not want it to perform. What is going on? Also, when I set up settings doesn't it work for all my laptops since I am signed in?

I like keeping my search bar clean. In addition to the Favorites star, now there is a "add tab to taskbar". On occasion (not sure what triggers it to appear) there is also a "Toggle reader view" icon as well. How can I control what symbols appear in my search bar. I only want what I need not what Firefox thinks I need. Dislike this feature.

CCleaner wiped out my bookmarks and their functionality. I have repaired, then uninstalled CCleaner. I have refreshed, uninstalled then reinstalled Firefox. I have logged in and out of Firefox. I have made an HTML file of bookmarks from another device in order to try to import them. Firefox bookmarks will not proceed to an upload stage. I went into setting to add the HTML of bookmarks and it said "this is not a bookmarks file." Well, Firefox made that HTML bookmarks file so I have no idea how that could be. Nothing I have tried has worked.

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 do not care it it’s optional. I do not care if there is a “kill switch”. Firefox should not be wasting it’s time on these features in the first place, as it has been nothing but an active detriment to the user experience on every platform on which it has been implemented. Nobody asked for this. Nobody wants this. I installed Firefox because I saw that it was different from other browsers, mainly in the way that it was not following the latest tech fads straight off a cliff. If the new leadership decides to change that, then I see no reason to stick around.

When I play YouTube videos in Firefox, the video stutters and drops frames, even when set to 480p. The audio continues to play normally. This issue does not happen in Chrome on the same laptop.

The problem started about a week ago. I’m using Firefox on Windows 11. Restarting Firefox did not resolve the issue. I’ve attached screenshots for reference.
