I have been using Firefox on my Mac computer at home and on my Windows computer at the office. Firefox started launching automatically when I booted up my office computer. This only began quite recently (since last update?). When I went to undo that setting, the browser prompted me to sign in, which had never occurred before to my recollection.

Today when I logged on to my home computer and launched Firefox, all my bookmarks had been changed to my work bookmarks.

Can my home bookmarks be retrieved?

Hello again.

In 2023, when I had Firefox v110.0.1, an unfortunate hiccup caused my handful of windows and their many tabs to not appear when I restarted Firefox. I asked for help here and jscher2000 was lovely and walked me through some things to do, which are discussed in https://support.mozilla.org/en-US/questions/1408206 and https://support.mozilla.org/en-US/questions/1396868.

Unfortunately, though I now have Firefox v158.0, this happened again a few days ago and I've been trying to retrace his steps the best I can with the newer version, but to no avail, unfortunately, partly because I don't now see a sessionstore.jsonlz4 file that jscher2000 referenced back in 2023.

(As I remember it, a system upgrade was taking place on my PC, and, also, a new version of Firefox {the v158.0 I mentioned} was also being installed, too.)

I found a Profiles folder (C:\Users\Bram\AppData\Roaming\Mozilla\Firefox\Profiles\p9f543mv.Default User\) that seemed to be relevant, and found a sessionstore-backups subfolder there. However, while that subfolder did NOT have a sessionstore.jsonlz4 file, it DID have files named previous..., recovery..., and (possibly connected to one of those updates), an upgrade... file, too.

When I first found this subfolder (in that "Roaming" area...I looked also in the "Local" area but wasn't confident I found anything more relevant), I copied/renamed previous... (with a timestamp from around the time of that system update, and large filesize) to previousOLD..., and the MUCH smaller recovery... to recoveryOLD, similar to the instructions in those threads. However, even if I also copied that previous... file to sessionstore... (to match those earlier instructions), Firefox would launch but with only the most-recent tabs (i.e., the Advanced Preferences {about:config} tab along with about:support {to provide Troubleshooting Information}) showing, as I'd launched them as part of my efforts to restore the session, and nothing else.)

I have "healthily-sized" recovery... and upgrade... files with the same date/time-stamp and filesize, though my efforts to try to get Firefox to open correctly have removed a similarly-sized previous... from that folder unfortunately -- hopefully the fact that recovery... and that upgrade... file have similar sizes mean they might(?) be valid substitutes for previous... should one be needed.

I hope that this described my situation well, but am happy to answer any questions you might have about it to the best of my ability.

Clearly, Mozilla updated some Firefox characteristics in the intervening three (3) years but I'm not sure how to adapt the new set of filenames to those previous instructions although, as I wrote, maybe one of those larger files will end up being what Firefox uses to try to restore everything...I just don't know what to do with it (i.e., what to rename it and/or where to copy/paste it) in order to make that happen.

Can you please offer some advice in this regard?

Thank you very much, Bram Weiser

I want to use your built in VPN. Every time while I follow instructions the process becomes circular. ie., when asked to click on VPN icon the same dropdown menu appears to activate by clicking on VPN button

Hi Guys,

 My password for MasterCard never reloads anymore.  I've followed all your recommendations and turned on "ASK FOR LOGIN" but nothing works.  
 It use to work before MasterCard changed the website to Citi Bank.
   Whenever I typed in the first letter of my username it would fill in the address automatically....
but now I have to type in the whole address every time ........

I've called MasterCard and they said call you ???

Thanks for your help, Peter Carbone

I have a lot of bookmarks and am always adding new ones. Suddenly, a couple of weeks ago (Oct 2026), when I go to bookmark a new page, the star goes from clear to filled-in dull grey, not bright blue as it always used to. In the same way, when I go to a previously bookmarked page (and I've checked this on about 30-40 sites, so it's not a specific site), the little star is dull grey, not blue. I can't make any new blue stars and I can't turn any old ones blue again. They are all dull grey and I find them hard to distinguish. Was this part of the recent Firefox 'new look', and if so, can anyone help me get my blue stars back? I'm using desktop (not phone).

With the push towards 2FA in many websites, I now need to use an authenicator, passkey, or physical token to access some websites.

I've chosen to use authenicators and physical tokens as my means of doing so.

However, whenever I try to use a physical token to access websites while in Firefox, there's no way I can find to do so. Firefox seems to default to passwords or authenicators... and there's never any way to actually select the physical token plugged into my USB socket.

So how do I get Firefox to recognize a physical token and to allow me to use it when accessing websites that I've already prepped to accept them?

I Have Windows 11 and Firefox version 158.How do I stop getting gray Mozilla Firefox pop up boxes with notifications in,sometimes get 2 the same.Firefox is my default browser.

Rogers Yahoo! Mail login is stuck because

the CAPTCHA verification fails or will not load.They said to Enable JavaScript: Ensure JavaScript is turned

on in your web browser settings. They have inserted CAPTCHA in the browser console ,but the error is at the server end.I talked to eight people at Rogers but they just ignore me and pass me on to someone else,I told them it was okay when CAPTCHA verification wasn't there.Thank you From Peter

Firefox is still suggesting alternative websites when I type in the search bar despite the fact that I only have the bookmarks suggestion enabled.

You can see in the uploaded screenshots that when I typed "FFXIV," the search bar brought up a page that is *not* a bookmark and is some random site I've never been to. My settings are set for only my bookmarks - or so I thought. What am I missing here? Is there another setting I need to disable?

For some reason, the time on my browser (time displayed on Discord and such), is one hour behind the actual time. I never had Resist Fingerprinting enabled and there's no setting anywhere to change it manually.

Firefox freezes some seconds or some minute after I open the program, I end task and wait to reopen the program, opening up the program it continues to freeze. I've reset firefox multiple times, cleared cache & webdata, completly uninstalled FF and reinstalled it, doesn't solve it. Starting firefox in troubleshooting mode also freezes and hangs. After end tasking firefox multiple times it eventually stops freezing but during the next day when I open the browser the issue returns, The same goes after I reinstalled it after uninstalling it, works for the rest of the day but the next day the issue returns. Background: I switched from chrome to Firefox some months ago and imported webdata from chrome to FF.
