Can you help me out, please?

To display this page, Firefox must send information that will repeat any action (such as a search or order confirmation) that was performed earlier.

Could you please disable your browser's Firefox addons just for a minute, make a post and see if you are still seeing that message?

How do I disable the Firefox browser's addons?

I don't want websites to store my credit card information. I always say don't save but even websites i have never used have my information. How an I prevent this from being done?

A few days ago my saved passwords all disappeared. I have been logging in manually and when I do Firefox asks if I want to save the password and I click yes. The password then shows up in the saved Passwords. But... in a day or so it disappears again. What's going on? I have not changed any settings.

All of my bookmarks disappeared. I have followed all the step to restore from the profile folder and to restore manually. It works to a point, then I get an error message saying Firefox is unable to process the backup file (see attached image). I even tried it in Troubleshooting mode.

I just bought a new laptop with Windows 11 and installed Firefox onto drive C: of the 1 TB SSD. I then decided to partition the SSD into three drives and put Firefox on the E: drive. After I partitioned the SSD and uninstalled Firefox, I downloaded the Firefox installer from Mozilla, and ran it, but it somehow perceives that I had had Firefox previously installed and only gives me the option of re-installing Firefox at the original (C:) drive location. There is no longer an option in the installer to change the installation location. How can I get around this and re-install Firefox on my E: drive instead of my C: drive?

Firefox Sidebar view only shows a 'Search' window and no Bookmarks or History lists

I have never had this problem before.
I can still view Bookmarks or History but only if I select it.

I use Norton Password Manager. I use Firefox most of the time as my main browser. I added the Firefox extension for Norton Password Manager when I got my new laptop, but it never does anything but hang when I try to utilize it. Today I finally turned off the extension and just ran the Password Manager as a new tab on the browser and had no problem with it running. However, it doesn't give me full use of the PM. (It does at least give me my passwords and user names, which the extension wasn't doing.) I keep notes with some of my passwords that are important to me. Using the PM on Firefox on this new laptop, I've found that none of the notes show up in the windows. Is there something I haven't turned off or on that's causing the problem I'm having? I use the PM on my iphone as well and have had no troubles with it. Thanks for any help. Sally 12/14/2025

I am at my wit's end with this. checked every single post on every website but nothing works. anything larger than 30 megabytes always fails in the middle and I have to keep resuming it. It also keeps giving me the same error message "Downloads\example.part could not be saved, because the source file could not be read. Try again later, or contact the server administrator." I have tried safe mode. I tried changing the download location, it still tells me that the .part file in the Downloads folder can't be read. This .part problem started recently after a firefox update for me. But the downloads getting cancelled for no apparent reason has been a forever problem. Is switching back to Chrome the only real solution? (I've been told this)

I designed a label in Avery, downloaded as a PDF and told my download to always open in Adobe Acrobat Reader. When I try to open the download I'm told that Reader can't pen because it is either not a supported file type or the file has been damaged. How can I change the program that opens my downloads? I'm using latest Firefox on a Windows computer.

I have about a dozen computers synced to Firefox. The Bookmarks go nuts when an older seldom used machine powers up. I spend days cleaning out my bookmarks only to have old ones come roaring back. I have began manually backing my bookmarks up to a hard drive. Firefox has failed me. I wish to delete all, or some of the backed up bookmark files.

How do I do that!!! I've spent hours over weeks online trying to stop this madness. Can I wipe out all the files by deleting any of the three "places.sqlite files? Is there a way to selectively kill the very large files that keep coming back and keep the other recent backups?

Does someone sell a pay to play bookmark manager similar to Foxmarks / xmarks?

Thanks for your help Lee

I recently installed v. 146 for both FireFox and Thunderbird on my laptop which is running Windows 11 Pro (Version 25H2 / Build 26200.7462). Since the upgrade to v. 146 I have been unable to use my older HP printer (Laserjet 2300d) on both products. When I try to print a browser page or e-mail using either the printer icon or the "File/Print" menu selection, the print dialog comes up like normal. However, when I click on the "Print" button, my screen flashes, the dialog box disappears, there is no indication from the printer that a file has been sent and no document is found in the print queue.

My newer HP printer/scanner (Officejet Pro 8130)works fine, as does printing to my older printer from MS Edge. So, the issue is with the Mozilla products. Using "Troubleshooting Information" and clearing the Printer cache has not resolved the issue for either FireFox or Thunderbird. Nothing else like this shows up in the knowledge base.

Do I have to retire my older, but dependable and inexpensive to use, laser printer in order to continue using FireFox/Thunderbird or is there a software solution?

I used to be able to download from these two web sites Israbox and Farescd.com, but lately it said data could not be verified. Sometimes it allowed but other times it won't . Please help. Thanks
