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

Hi,

I'm using Firefox on a Mac, and I'm having trouble dragging screenshots from my desktop into ChatGPT. I can upload images using the "+" button. Dragging and dropping images works in other browsers. In Firefox, dragging images into ChatGPT is unreliable or stops working. I have tried restarting Firefox and disabling add-ons, but the problem persists. I also tested a private window.

Could you help me identify the cause and suggest a solution?

Thank you!

Xubuntu 24.04.5 Firefox 158

Firefox used to position a new window on the screen in a somewhat predictable manner prior to 158.

For example, if there was a blank space on the screen between other windows, the browser would locate it and be placed there. A new instance would also appear on the active screen (I have two: left and right with a single window manager spanning both) where the mouse was located. Now the window is just placed in some arbitrary locations and may appear on the non-active screen.

I have a number of scripts that load various sets of windows on the screen (typically a number of xfce4-terminals and the browser) which used to pretty much work, but no longer as the browser windows can show up any place and must then be relocated. When I start a new session I have eight distinct desktops with many versions of Firefox on each. It is tiresome to have to relocate one browser window after another.

Is there any option I can set that would revert to the older screen placement algorithm?

Also, I asked this before and don't remember getting any satisfactory response. Why is the -geometry flag not supported on Firefox any longer? What's the opposition to giving the user control over this? I want some command-line method for accurately setting the size (WxH) and position (X:Y) of the browser window on the screen. Am I missing something here?

Thanks for any pointers.

How can I write a review for a Add-on? I already tried selecting a star which is supposed to pull up a review window, but the stars are dead links/not active. I've attached the page of the Add-on that I'm trying to review. Thank you

Hello,

For some inexplicable reason, when I visit any Wikipedia page (as of Thursday 8th October 2026), the pages display with a huge oversized font that also impacts the format and layout of the page in my browser. I have not made any adjustments on my PC to increase font display size. Wikipedia is the ONLY website that displays in this manner.

I am running Firefox 115.42.0esr (64-bit), which appears to indicate Firefox is up-to-date on my Windows 8.1 desktop PC. Please note that I am still running Windows 8.1 on this device out of choice.

I reported the fault initially to Wikipedia itself, and the response is that any fault is at my end. I have visited the same Wikipedia pages via Chrome Version 109.0.5414.168 (Official Build) (64-bit) and the pages display normally.

I have attached a sample screenshot to illustrate.

Any ideas how I can resolve this issue please?

Many thanks - Dean

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?

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).

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.

Firefox 157.0 is displaying some websites incorrectly. Newsmax pages turn white and McMaster-Carr is also displaying incorrectly such that I cannot make an order even if logged it. The same sites work correctly in Edge which I have an intense dislike for. I have already restarted Firefox and rebooted Windows. This started after the Firefox 157 update.

Hello, I wanted to add a passkey to my Firefox account, and to do so, I need to receive a confirmation code sent to my email address. However, this code is not arriving. My email is an alias (email forwarding is enabled). I have tried requesting the code multiple times, but unfortunately, I still cannot receive it. Furthermore, when I try to add an alternative email address - so that the verification code could be sent to a different mail - I am also required to authenticate using my primary email. How can I resolve this issue? Thank you in advance!

After an update (seemingly, I did not run 'sudo pacman -Syu'), the tabs have changed in look and to be frank i find the new layout ugly. How do I turn it back? Attached is a photo of the new tab groups, i couldn't get one of the circular tabs.
