Firefox abruptly factory reset itself after I turned my computer off and back on again. All of my themes, extensions, and bookmarks are gone. My phone, which was connected, is still normal and has my full search history+bookmarks.

How do I fix my computer?

(This is copied nearly directly from a post on r/firefox made a few hours ago—I decided it was best to spread it here for more exposure. The only change was the removal of the add-on names from the title due to character limits; these are Form History Control and Text Area Cache.)

I hope the title explains what I am looking for well. My main computer has had... spooky behavior with its file system recently, and I have been recommended to make a back-up, format my drive, and re-install my operating system (possibly upgrading from Windows 10 to 11 in the process). The biggest hold-up to me doing so is this, as I have no idea how to transfer the extension data between installs, or convert it into a human-readable form. The sheer number of writing drafts in those extensions both make losing them an unacceptable situation and copying the data manually into a document entirely impractical. So, can anyone help me with this? For context, I was on Firefox 138.0 when I stopped using my main computer due to those issues. (Note: It will certainly last long enough to do the Firefox Syncing and other back-up operations, just not for many more weeks or months.)

I reinstalled Firefox on my laptop after it crashed. I also have Firefox on my iPhone. The profile there is up to date. How do I sync that profile to the laptop installation?

Well being an OAP I needed new laptop. Always used Firefox browser but finding it difficult to get restarted. Had to opt out of window s to even download. Apparently I can transmit(?) my existing passwords etc from one laptop to another is this correct? Only basic computer knowledge but trying hard !! Karen x

Hello, I was wondering if there is a way that I can only sync certain things from my firefox browser to my firefox developer browser? Everytime I log in to my firefox acount on the developer browser it changes things that I don't want changed. For instance it will change the dark theme from the developer to the regular, and if I turn it off then it also turns off the dark theme on my developer addition, then I have to log out and fix everything on both of them. But it is nice to have my passwords on the developer addition, that is really the only thing I have found so far that I need.

Hello, I have been sending links from my iphone to telegram, then clicking each link individually to open in firefox and then saving all the links as bookmarks. Is there a way to send links from my iphone to my computer or firefox so that I can open the links as a batch or save them as a batch of bookmarks without individually clicking on them? I was thinking about sending them as I get the links on my iphone individually as html files, then highlighting all of them with my cursor and opening them all at once as separate tabs in firefox, then saving them as a batch of links (which I know how to do), but I don't know how to send links from iphone to my laptop as individual html files.

I tried firefox sync but it does not work well with iphone, because it will sync and sometimes delete previously saved bookmarks. So I'd like a new route if you have one. Apologies in advance if I should be on the apple or microsoft forum, please redirect me if so. Thank you so much!

The title pretty much says it - I have Chrome and Firefox on both my iPhone and my windows PC. I want Chrome to sync with itself on both devices (it does this just fine) and Firefox to sync on both (does this fine too). What I don't want is my history, bookmarks, etc. syncing between Chrome and Firefox. I didn't set this up intentionally but that's what they're doing now - my Google search history from Firefox is showing up when I open the main Google page in Chrome (on both devices). I'm not signed into my Google account in Firefox so I'm a little baffled by how this is happening. I have two completely different use cases for these two browsers and don't want them swimming in the same pool, as it were. Anyone know how to fix this?

Hi.

I have lots of Firefox tabs open on one laptop. I’m signed in. I have another laptop and want to open all those tabs in the second laptop. I’m signed in on the second laptop as well.

I can’t seem to figure out how to do that. Can anyone please give me step by step instructions?

Thanks in advance
