Firefox-Hilfeforum

Hi,

I always have dozens of tabs opened, if not hundreds. They have vanished. I’ve been trying to follow the topics on the matter, such as the one named ‘Session won't load’ (questions/1254740), to no avail.

Finally, this time I remembered not to close Firefox when I saw my tabs where suddenly missing. I’ve never seen the ‘Restore the previous session’ on the Firefox menu, and neither did I this time. Without closing the browser, I did a backup of the ‘sessionstore-backups’ folder. It contains:

‘previous.jsonlz4’, from 22/11/2020 17:42 ‘recovery.baklz4’, from 22/11/2020 18:57 ‘recovery.jsonlz4’ from 22/11/2020 18:58 ‘upgrade.jsonlz4-20201027185343’ from 31/10/2020 13:42 ‘upgrade.jsonlz4-20201108180448’ from 10/11/2020 15:05 ‘upgrade.jsonlz4-20201112153044’ from 22/11/2020 10:34

The one I need is ‘previous.jsonlz4’, since by 18:57 I’ve already lost my tabs. From the update backups I think I could also use the one from 22/11. In any case, I don’t understand what I am doing wrong so as to recover the ‘previous.jsonlz4’. This is what I’ve tried from different threads on my profile folder:

The ‘-backup’ and ‘OLD’ changes belong to different attempts

- Rename (on ‘sessionstore-backups’ folder) ‘recovery.jsonlz4’ and ‘recovery.baklz4’ to ‘recovery-backup.jsonlz4’ and ‘recovery-backup.baklz4’, and also tried with ‘recoveryOLD.jsonlz4’ and ‘recoveryOLD.baklz4’ - Rename ‘sessionstore-backups’ folder to ‘sessionstore-backupsOLD’ - Rename (on the main profile folder) ‘sessionstore.jsonlz4’ file to‘sessionstore-backup.jsonlz4’, and also tried with ‘sessionstoreOLD.jsonlz4’ - Copy/paste the ‘previous.jsonlz4’ file into the main profile folder. - Rename ‘previous.jsonlz4’ to ‘sessionstore.jsonlz4’

Nothing has worked. Once followed the steps, Firefox keeps opening my startup page. Note that it does not restore my previous session (that is, some tabs regarding this same subject), but my startup page, which means my attempts are having some effect, although not the desired one. I do have the ‘Restore previous session’ checkmarked in ‘Setting/General/Startup.

I also tried to replace ‘recovery.baklz4’ (on ‘sessionstore-backups’ folder) with ‘previous.jsonlz4’, from 22/11/2020 17:42, hoping to be prompted with the ‘Well, this is embarrassing’ + ’Restore’ window. I had no success.

I’ve been trying to recover my tabs for hour by now and don’t find what I am doing wrong. Why does Firefox refuse to load my ‘previous.jsonlz4’ file? Am I missing something? Maybe ‘previous.jsonlz4’ is corrupted or something? Should I try to use the ‘upgrade.jsonlz4-20201112153044’ from 22/11/2020 10:34 file? (Although I would lose some information)

Some people talk about a ‘History > Restore Previous Session’. I cannot find anything similar.

Thank you very much

I've recently noticed an issue with Firefox not loading some content for me. On one page it failed to load embedded videos, and when I contacted the site to alert them to the problem they troubleshooted and the issue seemed to be with my browser. A second time, when trying to use Instagram scheduler Planoly, I discovered that none of the images of my feed would display in the program, and again when I contacted support they could find no issue at their end.

I have followed advice and: - cleared my cache and cookies - disabled extensions one by one - scanned my machine for malware.

Any advice would be much appreciated.

I am unable to get the 'recommended by Pocket' panel to appear in new tabs with my normal user Firefox profile (Firefox account sign-in) on Mac Catalina. When I go to about:preferences#home the option simply is not present.

I created a new user login on my mac to access banking and other financials. This uses a separate Firefox profile (including new Firefox account sign-in and email), and the 'recomended by Pocket' panel is present.

The panel is present on new tabs opened for my normal Firefox account sign-in on my iOS (iPhone) Firefox install.

The about:config settings searching for 'pocket' appear to be the defaults, and match the settings in the financials account.

I have tried in 'safe mode' (add-ons disabled) and have done a Firefox 'refresh', however my add-ons (and presumably everything else) were restored when I signed back into my normal Firefox user account.

Hovering over the Pocket icon in the address bar displays 'save to Pocket', implying to me that it has signed me into Pocket. I've signed in at getpocket.com. New Firefox profiles without signing in do not show 'recommended by Pocket' in either new tabs or the about:preferences#home configuration page, but I expect the functionality requires being signed in to a Firefox account.

Help or suggestions much appreciated.

cannot log in to my Bank of Montreal online banking!!!

I've used Firefox for years, and for years I daily do my online banking.

Now all of a sudden, without any warning I cannot log into my bank account. I've tried clearing history, etc. I've tried the about:config change...

I can log in fine with Microsoft Edge.

My wife uses Firefox and she can log into the bank. I suspect that is because Firefox has not updated on her computer.

This is maddening, to put it mildly.

This is basically a copy of what I put in the Ubuntu forum. The problem is the same, no matter where I post it.

Originally I was using Ubuntu 18.04 LTS.

I thought it would be good to update to GG (20.10) though I did briefly try FF (20.04).

As the install was done on an existing 18.04 version things remained the same for programs, book marks, etc.

Ok, now the crunch: I USE Firefox ""A LOT"". When it loads, there are...... 8 x 6 windows of FireFox and each of those have anywhere from one to ""THIRTY"" tabs loading.

Believe me: ""It worked!!""

I could use it, also run other tasks as well - though a VM was pushing it with the RAM. But the entire machine worked.

Now, I am lucky if FireFox loads at all. Let alone let me browse.

When it loads some of the window's tops are flashing. A screen shot does not really show this. (I tried)

All that has changed is the O/S from 18.04 and Firefox from (what ever it was) to 83.0

I don't want this to be a finger pointing exercise between Mozilla and Ubuntu. I would prefer it is helpful to all.

What have I tried? I've tried starting FireFox with all addons disabled. Still happens.

I am going to try to remember to (next time) launch FireFox from a Terminal and pipe the output to a file to look for things.

The machine I am using has shown it is well up to being able to have this running. I have had it working for a few years like this.

This post is (for now) to establish there is a problem. I will post more information when I get it, rather than waiting to get it then post, as I feel there are a lot of people who have very similar problems and I want it known: ""You are not alone!""

Now a bit of extra stuff.

Other things which are weird: When I am watching stuff - youtube for example - the playback is/WAS jerky. I hadn't touched anything in the settings.

After digging around, I discovered that I had to turn ""OFF"" the hardware acceleration for the graphics. Question: How did it get turned on? (Semi rhetorical)

I have a lot of local pages I open with passwords. When I load them the CPU load goes through the roof and nearly invariably the program just exits. No crash report.

Which is a good 50% of how it happens. The other 50% is the machine just locks up and I have to power it down.

Even though I'm in the UK I was previously able to use the form auto fill function by changing the extensions.formautofill.available preference from "detect" to "on" however I updated to Firefox 83.0 and it reverted to "detect" and I am now unable to save any changes to it becasue it has always reverted to "detect" when I restart Firefox.

Form auto fill is such a simple and useful function that really needs to be available, Chrome has had it working for years.

Here is the crash info. Recently, usually when scrolling through sites, my tabs would crash unexpectedly. This is a brand-new laptop that I have had for a little over a week now. Any help would be greatly appreciated.

Crash Reason: EXCEPTION_ACCESS_VIOLATION_READ

Crash Address: 0xffffffffffffffff

Hello Community

Do hope someone can help?

Have tried all suggestions in Support area on topic: Lost/Recover Bookmarks. Also spoke to Windows Support and was told to call Mozilla Firefox Technical Support. I've been unable to find a number.

I had a Windows update around the same time as a Firefox update, May/June, only realised all saved bookmarks prior to June 2020 have disappeared. This has never happened before.

Urgently need to find out if there's a method of retrievel or have it confirmed that all of these very important bookmarks are permanently lost.

Thank you in advance

How fix this. Have googled the problem and tried all proffered solutions. No change. Others seem to have had similar problem, mentioning certificates, but got no help from Mozilla, that I saw. I have put the little jigsaw icon o the search bar, to no avail. Am deadended.

Hi folks. I know this is an easy question for you has me baffled. My old computer (Windows-7) has Firefox configured to automatically start my AOL account. But.......I can't recall the settings to make my new PC (Windows 10-Pro) do the same thing. Any ideas/suggestions welcome. Thanks Crady Adams

Strangest quirk happened recently. When I scroll down a Fox News article to the reader's comments, half of the comments are embedded with question marks etc. that make them unreadable. Not the end of the world but a little bothersome. When I use Microsoft Edge or Explorer this problem does not occur so it must be the Firefox browser. I am running the most recent #83 Firefox browser. Thanks for any help.

Hi,

I recently downloaded and installed some Android emulator named "Andy". Unfortunately, the .exe also installed all kinds of other Software on my Windows 7 system.

I removed most of the unwanted Software but one problem remained: A search result hijacker was part of the package. It replaces the top 4 results with some cryptic redirect links that are luckily displayed in a different font, otherwise I wouldn't have noticed at all.

I tracked the issue down to a addon in Firefox (see attached screenshot) that I cannot remove, no matter what I try.

What I tried to remove it: - I tried to remove the addon via about:config - I tried to run Firefox in safe mode and uninstall it - I tried to factory reset Firefox - I Installed Avira and made a system scan - I installed MalwareBytes and made a system scan - I check all the extension folders for addons that I do not know but can't find anything - I checked my whole system for any xpi-files but couldn't find any.

I am out of ideas. I can disable the addon but thats about it. After a while Firefox will shut itself down and the next time I start it, the addon is on again. When I resinstall FIrefox, the same thing happens. The addon is always back.

When I inspect the element it loads some invisible icon file that is supposedly located in "src="jar:file:///C:/Windows/Installer/%7BB28AF4A4-C997-4A5B-A111-FD1E65138A8D%7D/%7B02E337C0-4D70-452D-AA64-92D0A8C5D953%7D.xpi!/icon48.png"", if that helps. But the location doesn't exist on my system.

Can anyone here help me? I alread sent a problem report via the official tool.

Sincerely Florian

Suddenly tabs won't close & hitting "Command" & a link opens a new window instead of a new tab. Anyone know how to make tabs close & also how to revert to allowing "command" + clicking a link to open in a new tab & not a new window? I've tried shift + re-opening Firefox & I tried 'safe mode' & it's still happening.

When I wan't to use add-ons in Firefox for Mac, they just don't work. I can install them but they do not open. I have tried re-installing Firefox, installing the Firefox Beta (which supports Apple Silicon but crashed a lot) and restarting my computer, as well as re-installing the Add-Ons. Nothing works. How can I fix this?

I was asked to update my firefox browser now I have no passwords my sites are not remembering me by password, my bookmarks are gone. my history is gone my auto fill is gone why?

Yahoo has hijacked my searches from my Bing homepage and also from my Google tab in menu bar - I need to get rid of it as I find it select items that are of no interest and ignores what I have requested as my search.

Hello,

I have been having weird problems with my Firefox since I tried getting back to using it. I have reset everything before using it again. I changed the language back to English but the hamburger icon list is in Japanese. A minor issue but I can manage.

But this one is really annoying. I click on a link and it closes it down for me in 1 second. Here's a short clip of what I'm referring to.
