Within the last hour or so, I needed to close Firefox while installing an app (the setup was recommending to close all Windows programs).

Had 8 windows open.

Right-clicked on the Taskbar Firefox icon, then selected the option "close all windows" - it proceeds to close each window consecutively, asking me each time for manual confirmation whether to close this window with x tabs in it - and I just confirm each time.

So then after that setup is completed, I open Firefox again - the last closed window is restored (as per the settings);

then I click on History, "recently closed windows", and.... there's only 2 windows on that list. I restore those 2, and then the list is empty - nothing more to restore.

So if I had restarted the PC, it would've just restored the 8 windows upon reopening Firefox, as usual - but since I opted to just close Firefox like this, "close all windows", I just lost 5 windows.

So could anything be done here?

Something in the files? Maybe the C:\Users[user]\AppData\Roaming\Mozilla\Firefox\Profiles\4qu1kfr9.default-release\sessionstore-backups path? There's a file called "previous.jsonlz4" in there, something I could do with that one?

Or something else?

Any help would be appreciated!

Good afternoon, hi admin, regarding the latest update, please for the printer settings for landscape and portrait to be displayed on the right as before and permanently for the choice of portrait and landscape settings. because we are constrained by the print settings for PDF, we have to go to the printer settings all the time. please help for the next update. thank you for your concern.

I noticed this morning that the radar site of theweathernetwork.com has stopped working on Firefox. I am running the latest Firefox from OpenSuse Tumbleweed. The strange thing is Vivaldi also has the same problem so I suspected it's not a Firefox problem. So I logged into Firefox on my two other Linux distros, Debian and Fedora and Firefox has the same problem on them!!. Strange that Vivaldi suffers the same problem, the radar site never loads in Firefox, and in Vivaldi it sort of loads but runs VERY slowly. I tried restarting Firefox in troubleshoot mode and it got as far as a page saying some browsers don't support the site and suggested I update my browser. It appears the radar site has made some sort of change which two browsers under Linux cannot cope with. Unfortunately the radar site of theweathernetwork.com is the best of all the sites available.

Hi, The DM has an annoying popup that only appears on the sports page ( which is basically the only page I actually read, the rest of the comic I just skim ). I've searched the web for a solution but to no avail, hence my asking here. I have the popup blocker ticked, but this annoyance just keeps on.

cheers,

I had a personal certificate installed in Firefox and it was working well. It expired, so I got a new one from the same provider. Both appear in Firefox under "Privacy & Security" -> Certificates -> View Certificates... The previous one is not valid any more, and every time I try to access some page with a certificate, it uses the old one. So I tried to delete the old one. Nothing has worked so far. Doing the straightforward way of selecting it in the Certificate Manager and deleting it makes the certificate disappear from the manager menu, but if I enter the certificate manager again, it is there again. I tried to delete both certificates, same issue, both reaper in the manager. I tried to delete them, close firefox, delete cert9.db, cert8.db and key4.db and nothing. Only thing left is delete my current firefox profile and start again... Any other idea or something that I might delete before to solve this?

Why does firefox constantly ask for capchas on VPN when doing searches on Google? It is a serious problem. The vpn is for my security, not google.com

Steps to reproduce : - go to YouTube - open a video - press the full screen button or tilt the phone sideways to trigger full screen - Firefox crashes and forces back to home screen - if opening Firefox again only half of the video component shows as in portrait mode, rest is black screen - if attempting to go side/full screen does properly show the video, but going back again to normal screen still shows the half black screen

I can reproduce this with a almost 100% rate, it only fixes itself by restarting Firefox, where it will work until phone is put to sleep mode.

I tried reinstalling Firefox from scratch, as well as deleting my browser cache and it didn't fix.

Hello Firefox,

When loading a page I work on, I sometimes see something like this:

14:54:44.103 Error in parsing value for ‘margin’. Declaration dropped. instantiate_obj.php (With a yellow-ish triangle with an exclamationmark in front of it)

The warning is clear: somewhere in the html/css a faulty margin-value is used.

But how to find out where, or what causes it?

Is it something inline, an external CSS, something dynamically added by javascript?

What I tried:

1)  Clicking on the link on "instantiate_obj.php" just opens a tab in "view-source:" mode.

Not very useful. I don't see any problems on quick inspection, but the page is pretty big. I want something easier than checking everything in the source and the linked CSS.

2) Looking at the timestamp (14:54:44.103) I see it ends in 103. Maybe a linenumber?

Nope, that particular line contains only
.

3) Searching https://developer.mozilla.org didn't shed any light on how to approach this problem.

I can only find out references on how to do it when you see the yellow-ish triangle in inspector, in the second pane (css with that 'filter styles' on top) I already checked my external stylesheet and it came out fine.

Does anybody know how to find out what caused the warning?

===========================

I asked also on stackoverflow but didn't get a response, so for reference:

Thanks for your time!

Could someone from this amazing community go in and update it?

I just changed my Thunderbird to accommodate Microsoft Exchange (and had to enable the Owl add-on to do so). Now there is NO option available to set reply text at the top of a reply message. Replies are automatically set at the bottom after the first message in the string by default (which makes no sense and shouldn't have been the default). The option which used to be available in the Composition page of the Settings page is not there. How do I set reply text to appear at the top of a message as a standard??

Hello Mozilla Support Team,

Since one of the last updates firefox Download Setting seems not work properly...

Into Settings > Files and Applications > Downlods > Save files to option is ALWAYS on, even when "Aways ask you where to save files" option box is checked. When I open a PDF in view mode with Firefox, it automatically download it to the location described into "Save Files to"..in my case Desktop. It seems that the "Save Files to" option doesn't gray out when "Always ask..." option box is checked.

Do you have any idea why I can't chose just one of the two options?

Thanks for you help...

DIRECTLY after 114.0.1 update, I get a CONSTANT UNENDING PROMPT telling me all about firefox , ON EACH AND EVERY SEARCH, I am here to find out how to remove this intentionally annoying, "thing" from MY PC(of course Mozilla couldn't be bothered to tell us they were installing a continuous advertisement for google, and FORCE installing it as search engine). I want this endless advertisement removed, post haste.

Hi, not sure what I'm doing wrong, but my logins and passwords simply will not synch between devices. I principally use a desktop Win10 machine, and an iOS version of Firefox. Have double-checked settings on both devices, tried forcing a manual sync from each to the other, all to no avail. Any ideas on what I need to do differently? TIA.

All my search results now use google, thanks to the FORCED installation of the search engine google. Even after I have deleted it and deleted it and deleted it and deleted it and deleted it, ALL SEARCH RESULTS ARE NOW FROM GOOGLE, whether I like it or not. Mozilla has FORCED A COMPLETELY BROKEN SEARCH ENGINE ON MY PC(google), and now i can't rid of it, AND THEY ABSOLUTELY REFUSE TO HELP ANYONE.

Why is there not a simple means to take a link and pin it as a tile on my home page? I've expanded the number of rows displayed which as an odd history of my browsing, yet the latest links I've visited are not there - meaning the link to the location I would like to pin. Seriously, the entries in the rows (other than previously pinned links) is a hodgepodge. It might be useful if there was some evident logic to the items included. It is disappointing the number of times this question has been posed and the "answer" is to display more rows. Similarly disappointing - an old knowledge base article that says to click the 3 dot icon next to address bar for Firefox on android - would have been handy had such a control appeared in the latest version of Firefox I'm running on my Mac.

All my history, passwords and bookmarks got deleted on my local when I deleted my firefox account. This was not the intention and now I am unable to recover any of that? The logins.json file seem to be modified after this episode and I can't find a previous version. How to recover my passwords and history?

No matter what I do every time I close Firefox and reopen it all of the sites I am logged into log out.

I have reinstalled Firefox I have tried both beta and Enterprise versions. I have completely wiped all Firefox data from my appdata folders. I have refreshed Firefox multiple times. I have tried to mess with all the privacy, history, and cookies/cache settings and nothing has worked so far.

No matter what I have looked into the problem is not occuring the same for other people. It seems to be local to my PC however, as I am logged in perfectly fine on other Windows 11 PCs in my home.

The only major difference between the last time I used Firefox and now is that I reinstalled Windows11 to fix a bug with its calendar. I completely formatted so there cannot be any left over old Firefox files.

Hello,

after porting my SSD Arch installation from my old Laptop to a desktop PC, i have a really long startup time (about 30s-45s) for the first time after booting my PC. This problem doesn't occur with any other programs. The subsequent openings of firefox happen instant.

Have tried using "refresh" functionality to clean up firefox so my about:config is as clean as it gets, didn't help. Have tried starting it with "firefox --no-remote", didn't help. Have tried starting it with "firefox --safe-mode", didn't help. Have tried starting it with a completely fresh profile, didn't help. Tried purging it from the system and reinstalling it, didn't help. Same problem when I start it normally via dmenu/rofi.

I don't get any stdout log on any of these methods of starting.

I also don't know where to look for helpful log files.

Any help or hints on where to trace this fault are much appreciated.

Have a nice day :)

Reinstalled Firefox after a computer upgrade and now I'm stuck with a disconnected account and a sync loop. I login and it shows login confirmed but I look in the top right corner where you access your account and it shows that it's disconnected. On top of that, I backed up all of my tabs, favorites and passwords but I don't have the ability to import it from the back up. I'm only given the options to import from another browser. Any help in this matter is greatly appreciated.
