Forum d’assistance Firefox

Immediately on update to 96.0 this afternoon, multiple sites failed to load - Google(Maps, News etc), Yahoo, Flightradar24 etc - others partially loaded - then sat there blank. Explanation of errors is NOT clear -

Is it possible to revert to previous version? Everything seems to work fine when using EDGE!

Hi, I can't install Firefox and I don't know what's going on here.

Yesterday I installed the latest version of Firefox and it worked fine. Then, I turned off the laptop and the next day when I was going to use Firefox, it didn't load any pages. Edge was working fine, Chrome was working fine, but Firefox was not working. Trying to fix the problem, I decided to uninstall Firefox and installing it again. In order to clean even more the previous installation, I even manually deleted the C:\Program Files\Mozilla Firefox folder to remove all possible traces. I restarted the laptop and downloaded again the Firefox installer. I don't know how, but the installer detected that I had already installed Firefox before. I unchecked restart Firefox and hit the button to continue with the installation. After this, was impossible to install Firefox again. I got a message saying that the installation cannot continue because the VCRUNTIME140_1.dll was not found. The message said that this problem can be fixed by reinstalling the program, but that is not true, everytime I try to reinstall it, I get again the VCRUNTIME140_1.dll error.

After this, the installation stops and the Firefox icon appears on the desktop, but it doesn't install properly the software and when I open it, I cannot browse the Internet.

Do you know what's going on here and how to solve this?

Cheers

I need to use Google Meet for a professional purpose. When I use is from the Chrome browser, I can present a specific tab on my desktop; however, I prefer to use Firefox as my default Browser. The problem is, when I use Meet on Firefox, the presentation options don't include sharing a tab. Is there a way to fix this, or do I just need to use Chrome when meeting?

Thank you.

When clicking on an article link in an email from Wired, "Header overflow" is the only thing that is displayed in Firefox. It worked prior to latest upgrade. The link works fine when using Safari. Here is the link: https://link.wired.com/click/26376218.29116/aHR0cHM6Ly93d3cud2lyZWQuY29tL3N0b3J5L2hvdy10by1wcmVwYXJlLWNsaW1hdGUtY2hhbmdlLW5vdz91dG1fdGVybT1QNCZ1dG1fc291cmNlPW5sJnV0bV9icmFuZD13aXJlZCZ1dG1fbWFpbGluZz1XSVJfRGFpbHlfMDExNzIyJnV0bV9jYW1wYWlnbj1hdWQtZGV2JnV0bV9tZWRpdW09ZW1haWwmdXRtX2NvbnRlbnQ9V0lSX0RhaWx5XzAxMTcyMiZieGlkPTVjYzlkZmViZmM5NDJkMTNlYjFlNWY5ZSZjbmRpZD0yMzU2ODE5NCZlc3JjPUFVVE9fT1RIRVImc291cmNlPUVEVF9XSVJfTkVXU0xFVFRFUl8wX0RBSUxZX1paJm1iaWQ9Q1JNV0lSMDkyMTIw/5cc9dfebfc942d13eb1e5f9eDe873c205

Until yesterday everything I customized for Firefox 89 in June of 2021 and FF 91 in August of 2021 was working fine.

Today I updated to Firefox 96.0 and when I open my Firefox returned to that old visual that I hated

tabs with spaces , but that's not the worst. The worst is the newTab visual that came back to the small and ugly bookmarks of the page we usually navigate. That are set on userContent.css I remember.

I checked some vars at about:config and everything is as it was.

So do I need to set true or false any new var there? These .css files are like they was never read. It looks like to me there is a new var, we need to change it.

What did happen?

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

I have Firefox 96.0.1. As of this morning, images will no longer load on any websites. The only thing that has changed since yesterday is that I followed some advice from the Washington Post on how to prevent scam emails. I have spent nearly two hours searching for and following advice to restore images on Firefox, but nothing has worked. I need more direct assistance!

Fire fox updated t his morning now half my web sites I used yesterday come up with this PR_END_OF_FILE_ERROR, bing , yahoo, usps and faacebook just to name a few!!!!!! Not Happy!!!

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.

Hello, I am using a personal PC. So I don't require the Firefox to be managed by an organization. In settings it shows "Your browser is being managed by your organization" . On clicking on it, it says "The Enterprise Policies service is active but there are no policies enabled". I have attached screenshots for the same. Does any one know how to resolve this bug?

edit: fixed formatting cause by space before I am

Yesterday my firefox updated to version 96.0. It changed to screen to dark theme. I prefer the light theme and need help to change it back. Thanks

Email me at [email]@Hotmail.com.

The BBC website believes I am in another country, other than the UK. It currently redirects from bbc.co.uk to bbc.com, with some content no longer being available.

I have checked my IP, and it is currently a UK-based IP address. I do not have any active VPN profiles.

I have refreshed Firefox, deleted profiles, and redownloded but still the issue presists.

This problem is not reflective on any other browsers on the same machine.

Grateful for your help.

This is the BBC's advice, which I have followed - https://www.bbc.co.uk/contact/questions/behind-the-scenes/website-domain-change

I'm running Linux Mint 20 and have installed a free version of ProtonVPN. My firefox browser has a banner at the top stating "Your Browser is Being Managed by Your Organization". Not sure how this happened, but I am unable to update the browser because of this. I read some of the previous posts and they all appear to reference a Microsoft OS and Avast.

How to change the Tab color for inactive tabs?

I have a userChrome file and have been able to change the color of the active tab but cannot do so for the inactive tab. The inactive tab color blends into the toolbar color. If I move my mouse cursor over it changes to a slight darker gray color.

Active tab color. I made mine a off white color:

.tab-background[selected="true"] {

   background-color: #f9f7f1 !important;

}

Something happened to the Firefox browser (Windows 10) that caused a file named "old firefox data" to appear on my desktop. My passwords, bookmarks and other data have disappeared in the browser. How do I restore them?

This morning there was an Ubuntu software update and afterwards Firefox wouldn't work, it just opened and hung without ever connecting to a website. So I uninstalled, purged and reinstalled from Ubuntu Software and everything seemed ok. However, whenever I now try to save something, for instance images, the save to directory will default to /run/user/1000/docs even though I have my downloads folder selected in settings. I can change to the directory I want to save to and it will save there, but when I next save something it will again want to go to the /run/user/1000/docs folder. Further, I find that a copy of anything I save has also been saved into that folder, creating a new sub-directory to do so. I tried clear data in settings but that didn't delete those files and they are protected in file manager so I can't delete them myself. This will fill my hard drive pretty quickly as well as being really annoying having to change the save directory every time. What can I do to rectify this? I've now got version 96.0 (64 bit) installed.

On my convertible laptop (Windows 10 20H2) the on-screen keyboard doesn't open when clicking a text field with the keyboard flipped back and the tablet mode deactivated. In all other browsers I've tested the on-screen keyboard opens normally. Is there any workaround or plan to change this behaivour?
