Two days ago, my firefox browser started not restoring the previous sessions. I changed nothing in the configuration and I don't remember I had a crash. The option "Restore Previous Session" does not appear in the "3-bar menu > history" and it appears grayed in the History Firefox main menu.

What I've already tried or verified following the instructions of mozilla forum: 1) Settings > general > “Open previous windows and tabs” is checked as it always have been; I unchecked and and rechecked but nothing changed; 2) Settings > Privacy & Security > “remember history” is selected. Also tried to Settings > Privacy & Security > "Use custom settings for history" with "Always use Private Browsing mode" not checked. No success 3) I also deleted sessionstore-backups folder under my profile. The new created folder, even after closing some new sessions, has only the "recovery.jsonlz4" and "recovery.baklz4" files. There is no "previous.jsonlz4" inside which seems weird. 4) through about:config I checked that browser.sessionstore.resume_from_crash was true. In fact, I have Firefox in a second computer with no sessions restoring problem. I compared all browser.sessionstore.xxxx variables and the values are the same.

I still have the problem and do not know what to try next. Reset Firefox?

Hi guys. I'm on a Lenovo laptop, using Windows 11. Was NOT experiencing this issue (or any other issues) till today. That is, I've been able to download PDFs attached to Yahoo email for years, including recently (till today).

Trying to get Firefox to be DEFAULT instead of MS Edge, I changed some 'Apps associated with File Types', selecting Firefox as default for all file types that seemed appropriate, BUT, this issue then began.

Feeling I went too far, and should go step at a time, I reset All File Type settings back to default (MS recommended settings). Still can't open attached PDFs. I tried an Excel attachment and it opened fine.

Error I get is: "Firefox Can’t Open This Page To protect your security, dl-mail.ymail.com will not allow Firefox to display the page if another site has embedded it. To see this page, you need to open it in a new window."

The emails I used to recreate the error, were sending an email to myself, and attaching a PDF.

Other things I tried: I used Firefox with gmail email and the PDF attachment downloaded fine. I used MS Edge with Yahoo email and PDF attachment downloaded fine. Also, btw, CAN view a PDF attachment with Yahoo email. Just now download.

I CAN "open it in a new window" as the error suggests, than print to PDF, but don't want to live the rest of my life doing that.

Thanks in advance for any help that can be offered!!

Now all i have are the upgrade.jsonlz4 files, i know those are old session backups from when we upgraded. how do i go about restoring those as a session? when i follow the typical session restore steps nothing happens seemingly because its a jsonlz4 - XXXXXX file.

Any way to change it to a normal jsonlz4 file?

This story is a bit long, but please be patient.

I have used firefox for over 10 years, it can keep about a year's or 1.5 year's history (randomly expiration). So, I save places.sqlite per half year if I remember.

I have so many places.sqlite's backups. These backups proved that, in the past, firefox only delete some "expired" history records about one year ago or earlier in these years.

But suddenly Firefox started to only keep history in 3 months.

I save my profile in a path : "C:\Users\Admin\Documents\Firefox" and use -profile C:\Users\Admin\Documents\Firefox in shortcut.

And let's tell what happened(a bit complicated.)

I installed windows 10 in 24, July, in another harddisk. I entered the new windows, installed a firefox, and used my old profile as usual. It looks normal, until I returned to my old Windows 10, I noticed that, my history is kept for only three months and the left is gone.


I first thought that, the version in the new windows had wrong settings and deleted the old history, so I restored the backup, which is 2021.6.4-2022.7.24. But Firefox continued to delete my old "expired" history, after a while. This never happened before. (I am still in old windows now, from now on everything happened in old Windows 10)


Ok, I assumed that the new firefox in new windows 10 "comtaminated" my whole profile. After a really hard try I still can't find out what is the comtamination. So I created a brand new profile, copied:

all extensions and its settings, cookies, passwords, etc. just a few json and sqlite files.

And then I recovered the places.sqlite with my 2021.6.4-2022.7.24 version, which has about 60,000+ history.


And---guess what, firefox still deleted my old history.

This never happened before, for so many years.

Firefox used to delete "expired" history, that's true, but still can keep more than a year's records. But since I installed the new windows everything changed. I don't know why, and I don't even know their correlation between all these things.

I have to keep history more than a year because I need to check many records. 3 months is unacceptable.

Version: 102; which is months ago's version but it still delete my history! Actually I tried 100-104, same results.

I tried every possible idea, but it just delete my old history.

In conclusion, since the firefox(not international version, but local version by our country's official web) "comtaminated" my profile, I can no longer return the status that firefox keeps more than 1 years's record. I tried all possible methods, for example make a clean new firefox and only put my old places.sqlite(2021.6.4-2022.7.24) inside, but it just delete it to only 3 months left.

Everything sounds like magic. But I am a programmer too, and I don't believe magic. I checked the source code of history expiration. (decko-dev )(Yes, it doesn't have anyway to absolutely ensure preventing from deleting, but I can't find any code that just precisely keep 90 days' history, either.) I am not sure whether I found the right place.

My questions are below: 1. If firefox doesn't keep so many records all the time, then why I have so many backups with more than a timespan of 1+ years in these years(from firefox 20+ to now)? I used firefox for many years, I changed my profile or create new profile for so many times with so many versions, but none of them delete my history only 3 months left, at least give me one year+ left. 2.Did I correctly find the correct source code? 3.What triggered the firefox started to delete my "expired" history so precisely, only 90 days left? 4.I need a method to return to before 24.June, the time firefox history manager works well.

I am not local, so some words may be wierd, please forgive me. Any any information will help.

Hey all,

Last night I made the mistake of clicking a sketchy link on twitter thinking what it was some meme site( the person who tweeted is someone I know personally so I thought it was safe) once I clicked on it, I wasn’t redirected to the site so I thought it was weird then once I learned that he deleted it because it was compromised. I got scared and I was running scans through Microsoft defender. After the full scan it said that it detected Trojan:HTML/Phish!pz and the affected files where C:\Users\….\Local\Mozilla\Firefox\Profiles\cq0glqqq.default-release\cache2\entries. I deleted my cache a few hours later than I should.

So I reached out to a friend and they told me that it was probably was a false flag and I didn’t need to delete my cache. But I’m nervous that it’s an actual threat and I should do more to ensure my computer is completely safe. Also probably a lot of grammar mistakes I haven’t slept since I got this information.

I first realized an issue with downloading PDFs through the Firefox viewer - I cannot. The download button does nothing, there is no prompt, no popup, and no file downloaded. I have also tried to print to pdf, that also seems to fail.

Today I realized I also cannot attach any files to an email through Gmail in Firefox, which is now leading me to believe that the software is unable to interface with my files at all.

Things I've tried include: - Turning off popup blocker - Refreshing Firefox in the ->Help->More Troubleshooting Information Menu - Starting Firefox in safe mode - Reinstalling through snap

The only way I can currently download files is through wget, and the only way I can send attachments is by installing Google Chrome, which is kind of a last resort for me.

I am running Ubuntu 22.04, this is on Firefox 106.0, though it didn't work last update either.

Thanks for any help


Edit: I have been googling for answers but after posting this question a similar thread popped up, the solution is to install the following packages:

After upgrading to version 107, there is a huge space between the open tabs and the address bar. Can't figure out how to remove it. I am thinking it has something to do with the fact that I had enabled multi-row tabs. I can fill up that space with tabs if I open enough of them. In the older version that space was not there and the space would just expand to accommodate the extra row of tabs as needed. Any ideas would be greatly appreciated!
