Firefox supportforum

Previously this seemed to driven by an addin which I removed. Now each time Firefox updates itself every 1-2 days this problem reappears without the original addin. Because the chinese characters float over the top of the tab name it makes it difficult to read the tab name is is plain irritating.

Hello I have a bunch of tabs, and some of them get periodically replaced with some javascript code? I'm not sure, but i did find a few people that have exactly the same problem:

And further this:

Now ,my pc is windows 7 ,running whatever the last version (always up to date) of firefox was at the time (a few months ago it started and then happened a few times)

I still have the tabs sitting like there like that , and would appreciate if there's a solution. I would like a solution to prevent it from happening again and i want to understand what the meaning of the code is and if there's somewhere within it that i can find the lost webpages.

Thank you

Firefox was hanging up. I got frustrated and I ended the session using task manager. On restart my windows came back, but the tabs were missing the page information. I ended the firefox session again, and did a restart of windows for good measure, hoping to get everything restored.

Then, when windows restarted, I restarted firefox, and I was presented two options - SAFE MODE, or REFRESH. I did SAFE MODE. Things looked ok, so I ended that session, and tried restarting again, hoping to restart normally, without SAFE MODE on. I got the same two options again - SAFE MODE or REFRESH. So, I thought REFRESH would get me back to my prior session. Nope. That reloaded a bunch of things, like bookmarks, etc. and gave me a new session.

So, I looked under the three line menu. No ability to RESTORE PREVIOUS SESSION!

I also looked in my profile as found in ABOUT:SUPPORT - PROFILE FOLDER, and in my SESSIONSTORE-BACKUPS folder in my profile folder my RECOVERY.baklz4, and my RECOVERY.jsonlz4 have todays date as DATE MODIFIED, but only are 33kb each - way to small for the hundreds of tabs I had open in multiple windows - I believe.

So, do I have any other recovery session folders available that I might be able to use?

After I've installed Firefox 29.01, my tabs and windows from the previous season is not restored. In addition "ctrl+shift+T" hotkey is not bringing back the closed tabs.

Under Options/General "Show my tabs and windows from last time" is selected. Options/Privacy/History is set to "Remember History" Under about:config, "browser.sessionstore.restore_on_demand" is set to "true"

I tried to uninstall and reinstall Firefox 29.01 and 30 beta 6. Same results. I installed no extensions during these trials.

When I check my profile folder, I see that sessionstore.js or sessionstore.bak are not created, neither while Firefox is running nor after I exit. I have tried with a new profile as well. Same problem with both profiles.

I have used the instructions for changing the new tab page. This did not change the start page. Do I need to close firefox for it to take affect? If so it is not in the instructions. I used to have a Google start page but now it is from Ask.com and that is useless for me. I get no good results from Ask. I tried changing to Google, I tried changing to blank, still it does not change. Any suggestions on what I can try?

Last night I decided to check the monthly weather forecast just before going to bed. I googled, "weather" then clicked through to a website before realizing it wasn't the one I meant to click. I backed out and clicked another link further down the list. I thought to myself, "That's going to screw me up in future because the wrong website will be a visited link and I'll mistake it for my preferred site."

I'm a long-time Firefox user and upgraded to Quantum when it first came out. I had made a cursory inspection of some of the new features at that time, and remembered the little counter-clockwise arrow in the toolbar was supposed to be a shortcut for deleting a set time frame of browsing history. Remembering this, I clicked it and a little menu popped up with options for how much history to forget. I clicked the option to forget 5 minutes.

I'd had multiple windows with multiple tabs open and they all disappeared instantly. I don't know if the browser crashed or simply intended to restart itself, but when it reopened there was only one window with no tabs.

I quickly hit the three bar menu button in the top-right and navigated to Library > History > Recently Closed Windows. Both this menu and Recently Closed Tabs were entirely empty.

My secondary Windows were of secondary importance, but my first and primary window had a large number of pinned and ordinary tabs that I did not want to lose. Tabs that I have been saving for months - some more than a year. Many that I migrated from Firefox I to Quantum. In the past, they have always been recoverable through the History. Now they seem to have been erased without a trace because I clicked, "Forget 5 minutes" from the toolbar.

I tried using Window's System Restore to reset my computer to a restore point from yesterday, but this had no effect on my Firefox session. Is there any way to reverse this and recover the session I've been using daily since before Quantum had been released? Is it anywhere?

Hi, Firefox 67 recently automatically downloaded onto my Mac computer that uses High Sierra. Since it downloaded, when I quit Firefox and then reopen it, it no longer restores my previous sessions even though it is checked in my preferences to do so. I have to start all over when I open Firefox and this is the first time this happened since I have been using it for over 15 years. What can I do please? Thanks.

HI, I've been struggling the last few days to get back all the opened tabs I had in my Firefox window. My deault setting was to resume the Firefox session from where it was when I last exited Firefox. But some weird toolbar got somehow installed in my PC and when I uninstalled it all my browsing history was deleted (from all my browsers, IE, FF and chrome) and my precious Firefox tabs were gone.

These tabs are really priceless, I collected them through some months of research and it would be impossible to redo all my work. Although I managed to find some of these sites in my browing history when I restored all of it via the "restore" function in places.sqlite file properties (in the "previous versions" tab), it's impossible to find the other sites I need by checking every visited site in my browsing history, there are thousands of them and it would be the same as starting all over from scratch.

I know too that it was unbelievably stupid of me to not bookmark these sites before, but please, isn't there any way of retrieving those lost tabs? What irks me the most is the fact that the tabs weren't loaded when I opened Firefox, but only when I clicked on them, which means that I have no clue on which dates to find the tabs, since they were only visited at the time I found them, and never loaded again.

I'd be most grateful to any hint that might solve this problem. Thank you for your attention.

PS: I should mention I've already tried Window's "System Restore" but to no avail; when I open Firefox, after having a previous session restored, it will display the same tabs I left recently (as opposed to my previous tabs, that remain lost). My OS is a win7 64 bit Ultimate

I am using FF 31.0 on Windows 7 Professional 32-bit. I have a number of FF windows open, one for each project on which I am working. There are some tabs in wndows that I do not want any more. So I either close those tabs or go to other URLs in those tabs. I then cleanly exit FF. But when FF is restarted, the tabs that I had closed or changed URLs re-appear, as if I had done nothing to delete or change them. I assumed that FF, when it exited cleanly, would save all of my current windows and tabs settings, and when I "restored my previous session", I would get the same windows and tabs that I had when I cleanly shutdown. But this is not the case. How do I tell FF to save my current window and tab settings? Thanks.

Before shutting down Firefox I deleted history/cache/passwords etc from the past day

I do this all the time but since I had restore previous tabs selected they always get restored when I start up again

However this time they weren't restored when I restarted

Without closing Firefox I navigated to the sessionstore-backups folder to see what was there but the files were only 2KB - much too small for the number of tabs.

So I installed ShadowExplorer & Shadowcopyview to see if I could recover older versions I was able to locate jsonlz4 files from a few days ago that were around 11000KB in size so I assumed they would have most of my tabs

However when trying to use the files nothing happens - I tried 2 different steps that I read here had worked for others

1 - Renaming previous.jsonlz4 to sessionstore.jsonlz4 , moving to the profile folder (deleting the old one first) and restarting FF

2 - Deleting sessionstore.jsonlz4 and copying the recovered previous.jsonlz4 / recovery.baklz4 /recovery.jsonlz4 / upgrade.jsonlz4-20201014125134 files to the sessionstore-backups folder and restarting FF

I also repeated the steps after creating a separate profile

None of these worked so I tried examining the jsonlz4 files using https://www.jeffersonscher.com/res/scrounger.html but I got an error message 'Session history file contents could not be read?'

Now I've previously used recovered Jsonlz4 files to restore tabs with no issues but this time they won't work

I read here https://support.mozilla.org/bm/questions/1189759 that updates may cause compatibility issues and the upgrade.jsonlz4-20201014125134 file indicates they was a recent update

The recovered file sizes indicate they contain data so I want to know how I can recover it - if not through FF then through some other software

One day the tab titles partially dropped down off the black strip of the tab bar into the web pages. It is now very hard to read the titles. How do I get them back up? Thanks for your help.

When I click on the URL bar, the whole URL or whatever i type in is indentured to the right. I reinstalled Firefox and the problem was gone. But after two days the same occurred again out of nowhere.

I normally have more than 1 tab open and Outlook is one of them. When I am on another tab, I normally see number of new emails received when new one arrives. But this is not the case recently.

In the new interface on Firefox (which started for me today ... May 2 ...), I cannot open a new tab via the "+" sign along the top or by using Ctrl + T. If I want more than one thing open at the same time, I need to open a "New Window", which doesn't make much sense. I don't necessarily want a bunch of windows but may need a few tabs open at the same time.

I have many tabs like 200-300. Firefox crashed today. I also have 4GB page file on top of that. Strange! After I restarted Firefox it was using only 6.8GB RAM. Perhaps memory leak. BTW if I have browser.cache.disk.enable set to false. Is page file still used?

Thanks for help.

New ver. of Mpzilla has same bug. Tabs cannot be re-loaded. Have you sSERIOUS idea what to do ? I imported file to another PC JSON and HTML files and loaded it. Bookmarks are supposed to be ok. However in this case there is another bug - TABS DO NOT OPEN So pls make a brainstorm - 1. on my old PC how to re-load or open anew tabs  ? 2. on the new PC how to open tabs  ?

Regards Maxx

After recent update, when I start ff, there's always this page showing: https://www.mozilla.org/en-US/firefox/29.0.1/whatsnew/?oldversion=16.0.2

I went to option->general->home page and changed it to google.com, but everytime I started ff, above page still show. I googled around and couldn't find a solution.

Please help. Thanks.

On re-opening ff all of the tabs to the left of the last open tab have re-opened as per normal but none of those to its right.

There are far too many to try to re-open manually one by one.

HEEEEELP MEEEE!!!!
