Firefox Community Forum

I rebooted my laptop to find that Firefox removed all of my data. I looked up for ways to fix this and then arrived at the conclusion that I could create a profile and set the folder to one of the profiles that weren't listed on Firefox. It seemed to save my history correctly and my saved downloads, but they all said that they were moved or missing. I checked the passwords and instead of the long list of passwords that I normally have, there were only a couple, and the passwords were also sometimes outdated. I cannot recover some of these passwords. I've tried checking the passwords in the other profiles that were listed in the profiles and nothing shows up. None of the cookies were saved either

firefox suddenly stopped showing any history or book marks. also no history. i've re downloaded, no change. all works well with chrome but i like firefox. and thoughts?

I went to [https://support.mozilla.org/en-US/kb/firefox-backup] and under "Create a Firefox backup file" at step 3 it says, "Scroll down to Backup, and click Manage backup" but when I went there no such "Manage backup" option exists as you can see in the attached screen capture. So what gives? How can I "Create a Firefox backup file"? I am using Firefox v147.0 (64-bit) on Windows 11 Please instruct. Thanks RJB

As of 12/9/25, Firefox seems to now prevent Theme add-ons from working if there is a contrast setting configured in Windows configuration. (Version 146.0) Previously, this allowed a very aesthetically pleasing view. I would greatly enjoy having that option again. Thank you.

Good morning,

I have been using the Dashlane Password system on my desktop for several years and it works great with Firefox, however, Firefox was recently upgraded (automatically) to Firefox version 145. Now I can no longer access the Dashlane application which contains all of my passwords. What should I do to recover my Dashlane application?

I noticed recently, that you cannot copy and paste with the right click mouse buttons and seems to want me to use the Cntrl C and Cntrl V. Is there some way to re enable that on the mouse? It works in every other application except firefox, and I would prefer to use the mouse, as I am the most comfortable with that.

For some reason after I restarted my laptop (firefox was opened) Mozilla was reset. I was logout from my acc and also firefox isn't my default browser (I didnt anything with it). Btw if I tried to open any link system will open it via firefox. But firefox still said that its not default browser in system. And if I open default apps in Windows I have 2 firefox there (and both recommend me to set is as default). Except FF I have only edge that also said that I can set is as default. After I login in my acc in firefox I haven't anything. No history, no passwords, extensions etc. What I can do here? I tried to use sync but as result I still have nothing.

Never cough smth like this before in same cases.

How do I remove the pop up blocker on Firefox for certain websites? I am doing an online course and each introduction for each chapter has a short video that pops up but as soon as that happens Firefox sends a "Critical error" message then the video stops so I thinks that's happening because pop up blocker is turned on and I just dont know how to turn pop up blocker off for specific websites only like this one I am using for my study course. How can I turn the pop up blocker just for this one website so that this doesn't keep happening?

Javascript is not working in my firefox. Even going into settings to enable java script doesn't work, because it says java script is enabled. But the webpages tell me that they need javascript enabled in order to work.

When I access Facebook via Firefox browser there usually are issues - site does not load properly, videos stop working, and more. I do not encounter the same problems with other browsers.
