A few updates ago, headers and footers started appearing on anything I print from Firefox. No other printing from any other source does this. All the settings (advanced settings) show header/footer as off, and 'none' in all the header footer options. I have attempted every combination available and can't get rid of the headers and footers. I Don't Want Them!

Добрый день. После последнего обновления Firefox появилась проблема. Суть такая, При перетягивании вклдаки с одного окна Firefox на другое они не объеденяются. А переносится как новое окно. А в окне в которе переносится появляется синяя полоса и висит так бесконечно. Еще вчера, до того как я обновил до последней версии все работало нормально. Помогите решить проблему.

Google translate: Hello. I've encountered a problem after the latest Firefox update. When I drag tabs from one Firefox window to another, they don't merge. Instead, they move as a new window. A blue bar appears in the window being moved, and it hangs there forever. Everything was working fine yesterday, before I updated to the latest version. Please help me solve this.

I had automatic updates turned on for Firefox on my older Windows 10 Thinkpad. Update 154 (64 bit) has made my machine fail to connect, run very slowly on loading sites and caused mailchimp to malfunction. I have already spent hours trying to undo all the damage, but the sites are still loading very slowly. Can an update be reversed easily? Do I just need to change some settings? I have cleared cache and site data several times over, set tracking to standard and added mailchimp to ublock exceptions. What else can I try?

I hit the "Clear Private Session" icon, confirm, but then I have to go to:

Open Settings >

Privacy and Security >

Browsing Data >

Clear Browsing Data >

"Everything" (every check box has to be checked) >

Clear.

I have Firefox in permanent Private Browsing only, and Privacy and Security Settings are set to Strict / Do Not Fix any site problems.

Why does Firefox retain browsing site data even after I exit out of Fiirefox completely unles I do all of the above?

I have the latest version of Mozilla Firefox 155.0.Every time i update to latest version my Norton 360 for Gamers antivirus Safe Web application blocks the update process and i report it as False Positive and Mozilla Firefox updates ok. I have attached and image of Norton's Safe Web application analysis. Also,have submitted this issue to Norton using their Report False Positive form and have not had a reply yet. Thank you

Hi I've attempted to disabled the entire new block of 'Stories' but they continue to show up cluttering my screen. Why isn't 'disable' working? How can i get rid of everything except the search window and my single line of helpful links? Gary

I work for a school district. At some point over the summer, a Firefox update started triggering my districts web filters. The filter says it's connected to Firefox VPN, but I don't have the VPN turned on. After a minute or two, I am able to access the internet normally in Firefox or any other browser.

There must be a setting or something in Firefox that triggers this since I can use any other browser normally, but once I open Firefox, everything on my computer is blocked from internet connectivity until the timeout is over.

I have switched off the "story" but want to get rid of the overlay for this. How can I do this. It is visually offensive to have this big gray blob in the middle of my screen. I have been loyal for firefox because I do not want this kind of intrusion.

Hi, I believe this is some kind of bug/issue after the latest browser update (as I've quite literally never had this issue before). I like my launch page not to be cluttered with nonsense, no widgets, no activity, just my standard pinned shortcuts and the google search bar. However, after the latest update, "stories" have been on and have stayed on (despite altering all the settings that should get rid of it altogether). Even after turning it off, it appears it turns itself back on immediately. I don't want to see this junk and shouldn't have to, no one should, I even went to the trouble of blocking all topics in hopes the thing would just vanish. It did not. I hoped to report this to Mozilla more directly but couldn't find a meaningful bug report option. If anyone else has encountered this or if anyone has a true solution, I'd like to hear it, thank you.

Only with Deepl, I click on this program and immediately I get a window which says "Checking if the connection is secure". Underneath this, I have to check a box which says "Verify if you are human", with the Cloudflare logo.

I've tried everything to get rid of this as it slows me up. I've tried Settings/Installed Apps, Search, Programs etc but it is not contained in any of these lists. I contacted Cloudflare who gave me some suggestions which didn't work (can't remember them), then said it was part of Mozilla and it was them that have attached this window so I need to contact you to get rid of it.

Can you help me please?

I have a new Windows 11 lap top and have been trying to make Firefox work the same as on my Windows 10 laptop. I looked at "Bookmarks import doesn't show bookmarks on title bar? " and tried to follow the instructions. The result is that the bookmarks toolbar contains both "Import bookmarks" and "Bookmarks menu" but not the actual Bookmarks Toolbar titles. The Library shows:

   *All Bookmarks                   (The asterisk is bold inside a square)
         Bookmarks Toolbar
         Bookmarks Menu

              Trade
                (et al)
   %Other Bookmarks           (% is actually folder emoji)

As you can see, I am going round in circles. I do not understand properly how bookmarks work. On my old Winows 10 laptop, I managed by trial and error to get something that I could use, but now I am mostly getting error.

Firefox prompted me to update, I hit download, my entire PC froze, I restarted the computer, when I opened firefox again and hit "restore session" it restored a session that I had opened months ago. When I checked my history, everything after that older session had been deleted. All of my history from the past few months has been deleted. I tried a few different solutions from trying to research the problem, nothing so far has worked. The only thing I have found is a session restore error saying "could not decompress file", but I could not find the file it was attempting to decompress. This is the error message I found.

1785894397652 SessionStore ERROR NotReadableError when reading session file: recovery: NotReadableError: Could not read `C:\Users\ansen\AppData\Roaming\Mozilla\Firefox\Profiles\xpnhovd6.default-release\sessionstore-backups\recovery.jsonlz4': could not decompress file: invalid LZ4 header: wrong magic number: `00 00 00 00 00 00 00 00 00 00 00 00' (NS_ERROR_FILE_CORRUPTED) No traceback available 1785894397756 SessionStore ERROR NotReadableError when reading session file: recoveryBackup: NotReadableError: Could not read `C:\Users\ansen\AppData\Roaming\Mozilla\Firefox\Profiles\xpnhovd6.default-release\sessionstore-backups\recovery.baklz4': could not decompress file: invalid LZ4 header: wrong magic number: `00 00 00 00 00 00 00 00 00 00 00 00' (NS_ERROR_FILE_CORRUPTED) No traceback available

Any help is greatly appreciated. I'm one of those people that tends to have way too many tabs open at once due to poor memory, and losing months of tabs and progress is a huge setback. I'm very desperate to get the history and tabs back.

From Firefox, I have launched Earthlink Web Mail. When reading an email, scrolling doesn't work. It worked yesterday from firefox. It works today on Edge. It works today on my Android phone.

Now when I click on something in Firefox, for example a Facebook post, it opens in full-screen mode, not just in the selected window size. When the new window opens in full screen, it covers other stuff already on the desktop. It's f'ing annoying. How do I choose to have new windows open at the existing window size?

I am using the latest 155.0 build of Firefox on Windows

Edition Windows 11 Pro Version 25H2 Installed on 21-08-2026 OS build 26200.9278 Experience Windows Feature Experience Pack 1000.26100.360.0

Recently, probably around a few weeks ago, I have found that i am no longer able to reorder tabs using the mouse left click and drag to reorder.

The mouse is working fine and I am able to do the same reorder on the Chrome browser however it doesnt work on Firefox anymore.

The only way to reorder tabs is to use the popup menu and select Move Tab.

Kindly fix

Regards Sanjay

Issue persists on Incognito Mode and it goes away if I use different browser.

Since 2 days issue like this happened and it is retroactive meaning all previous conversations are also blank, all replies of chatgpt are blank except replies with image generation, those are fine.

Before you recommend me to do something please keep in mind that Incognito itself does not help.

I am able to share that chat, paste it in my firefox and page is blank. https://chatgpt.com/s/t_69f4b354cc188191a7959c2d443fed9d

I can use this adress on different browser and it works fine

After today (Sep. 2, 2026)'s update, I noticed that the the plus "+" button for new tab is canceled. Instead, I have to now click right on the work function and click "New Tab" for a new tab. This revision is quite counter-intuitive. Could you please add back the plus "+" button for new tab in the next update?

Thank you very much.
