Firefox Support Forum

Before updating to Firefox 96, I could close tabs no matter how squished they were. Now I cannot. Someone with a similar problem at https://support.mozilla.org/en-US/questions/1194322 was able to find help, but I'm not meeting with any success implementing their chosen fix. Is there a way to keep the close tab button active with this many tabs anymore, or is that out?

Dear Mozilla/Firefox,

I've been using Firefox over the last couple of months/years but I just can't get the restore recently closed tab shortcut (CTRL+SHIFT+T) to work on my windows PC.

Here's a (Loom) recording of me showing that Firefox does correctly track the history of closed tabs and that I can click on them to restore but the shortcut (which is also mentioned as CTRL+SHIFT+T) just won't work: https://www.loom.com/share/7048894683654dccb4926aa4dd09e6a6

What I've tried so far: - Check if the history is actively collected - No I'm not using private browsing - I've read another support thread to check "about:config" and in there check that "browser.sessionstore.max_tabs_undo" is set (in my case it's the default 25) - Disabling all extensions (which I don't think are any suspicious or weird ones but disabled just to check - see attached image) - Resetting Firefox through the windows uninstaller - Fully uninstalling (using Revo Uninstaller with advanced check) and reinstalling Firefox

Please help me because I'm about to quit Firefox for such often used feature just not working...

P.S. it's working perfectly on my Macbook and I'm running the latest 96.0.1 64bit version

The Firefox Sidebar is a very nice feature that I use to provide favorite bookmarks to an non-computer-savvy elderly parent. Unfortunately many times the "X" in the upper right of the sidebar is accidentally clicked which results in a phone call or remote login session to recover. It would be helpful if there was an option to "lock" the sidebar so it cannot be closed by an unsavvy user. In addition, it would be valuable if the sidebar lock prevented the user from collapsing/expanding (changing) the bookmark lists in the sidebar. Once they are "locked" (by a computer proficient person), no changes are allowed to the sidebar by a careless user.

I am on MacOS X with the latest firefox. I refreshed it and disabled AV and all plugins, it still crashed.

There are also no logs of the crashes I can find.

What should I do to enable them, or diagnose further?

Hi

I had two Firefox windows open. One with 100+ tabs and the other with 1 tab. I closed the Firefox with 100 tabs, and then closed the one with 1 tab, without thinking. I then realised that I should have closed them in the opposite order, because I want the 100 tabs to get restored.

I opened Firefox again and was dismayed to see just the single tab get restored. I did some searching and backed up the "sessionstore-backups" folder.

I then tried to close Firefox and replace sessionstore.jsonlz4 with previous.jsonlz4 from the backed up "sessionstore-backups" folder. This did not work, as when I opened Firefox I still only got the 1 tab back and "recently closed windows" remains grayed out. Ctrl+Shift+N does nothing as well.

I used https://www.jeffersonscher.com/ffu/scrounger.html to inspect the backed up previous.jsonlz4 file and it shows

Open Windows Open Window 1 Tab 1 [...]

Closed Windows Closed Window 1 Tab 1 [...] [...] Tab 125 [...]

So the previous.jsonlz4 file does contain my mistakenly closed window but I can't get Firefox to restore the tabs!

Can anyone please help me get my tabs back? I'm on Firefox v96.0.1.

Hi; When I close FF (V96.01) it does not seem to close properly and when restarted trys, usually unsuccesfully, to reopen previous tab. I have , open previous tabs and windows, unchecked in settings. I have tried both the X and exit. If I set, browser.sessionstore.resume_from_crash, to false in options it does not happen. as per https://support.mozilla.org/en-US/questions/1292610. But when I reset session restore to true the problem resumes. This makes me believe FF is not closing properly Win10 is up to date with all latest updates as is FF.

Is there a fix for this?

I need to set up an outlook mail account for a part-time employer. I was advised to use a different browser than the one I use for my day job, so I chose Firefox. I have a user name and password. How do I proceed?

Hello, i had microsoft edge since i bought my laptop which i usually get rid of instantly. But recently i started getting these errors especially trying to go to the T-mobile website. The errors i'm getting are " Secure Connection Failed An error occurred during a connection to www.t-mobile.com. PR_CONNECT_RESET_ERROR " . Any idea how to fix this?

My appearance settings are set to dark mode but Firefox is only displaying in light mode. I've tried downloading various dark mode extensions to fix this, but they only seem to work on websites other than the firefox homepage or settings.

every once in a while firefox would just not load youtube and I have to switch to something like chrome to get on that site, and today after firefox updated i now just get the "Secure Connection Failed" error message and get told to contact the website owner like lol. and i understand there's an error and the connection is not secure, but like it's youtube... before it updated i cleared the cache and that fixed the problem of it not loading, but now it just goes straight to an error message. i tried troubleshooting a bit and nothing really changed, anyone have any way I can just bypass this?

hi, it has been 2 days since firefox starts to behave in an unusual way. when opening many tabs, and if i dont click on them (ie inactive) in 2-3 minutes, they go blank. when i click on an inactive tab, firefox quickly refreshes it and shows the page. example: let's say i have 3 open tabs: tab1, tab2, tab3. i am reading in tab3 for 15mins. in that period, i didnt click on tab2/1. if now i click on tab2, it is blank and no longer displays the content of the page it is supposed to show. then, firefox quickly refreshes the page and displays the true page.

not really sure why this is happening now. never happened before. it is a really annoying behavior as every tab had to be refreshed automatically if i dont click on it in very few minutes. firefox 96.0 ubuntu 18.04. thanks

Hello!

I am multilingual and write in multiple different languages, and the red markings from spellcheck underneath non-English sentences get annoying when they are so frequent. I understand that I can install multiple dictionaries, but that does not allow me to use more than one language's spellcheck at a time.

Is it possible to activate 2+ language dictionaries in Firefox?

Thanks for the help, Sylvan

I recently deleted all cookies & site data & now whenever I search for something using Google I get the following message (below) where I also have to fill out a Captcha in order to proceed. This only happens with Firefox. On the same computer I have Microsoft Edge which has no problem with Google search. What's the problem with Firefox? Will give up this browser if this continues.

Hello,

I connected my router to my PC via ethernet cable and I want to change the SSID and password but the site router.juplink.com is flagged as insecure. I get this message:

"Warning: Potential Security Risk Ahead Firefox detected a potential security threat and did not continue to router.juplink.com. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details. Learn more… router.juplink.com uses an invalid security certificate. The certificate is not trusted because it is self-signed. Error code: MOZILLA_PKIX_ERROR_SELF_SIGNED_CERT View Certificate"

Please advise.

Thank you, Mlichael Pilger

Someone has logged into my new laptop's Firefox, I've changed my password but they keep logging into my accounts... paypal, amazon, credit cards. Please help me. They've charged almost $500 already
