This is the 2nd issue arising from a v158.0.1 update disaster. FF won't print a page: it seems to start, and then blanks the screen, returns to windows wallpaper. the printer stirs but prints nothing. The printer tested OK from the windows test page. As recommended in the fix suggestions, I tried the clear printer option in troubleshooting, but that does not work. How do I fix this??

Using windows10 on the ESU program on this machine.

This category seemed the most appropriate from the list. Bookmarks are the first of 2 issues I need help with.

On my first start after upgrading to v158, all my bookmarks are missing, normally shown in a sidebar. All the suggested means of getting bookmarks back via a profile simply did not work: the restore panel asks for a file and all the various bookmarks in a profile are in a folder. the 2 did not mix. I do have exported bookmarks as a json file, but obviously it's hidden for FF, but not for explorer. Nothing recommended in the articles worked. In frustration, I removed the software and downloaded a new copy. Same issues applied. I copied the latest json file to the desktop, and restored it from there. AND after a restart, there were none of those bookmarks on the browser page. BUT selecting managing bookmarks and there they all are.

So how do I get the bookmarks from the management page to the normal user interface??

I am running win10 in the ESU program on this machine

When I try to open Firefox browser, it keeps giving an error message stating that the browser is already running. I've tried to clear cache and other recommendations that were provided, without any success. I am unable to even get on the landing page of Firefox, the one time that I managed, all my shortcuts were missing!

Be careful. Something doesn’t look right.

Firefox spotted a potentially serious security issue with schoolscholarship.cg.nic.in. Someone pretending to be the site could try to steal things like credit card info, passwords, or emails.

schoolscholarship.cg.nic.in has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site.

How about moving the pop up away from the original text, so we can see both at once?

Or show the original text in the popup as well? It really helps to be able to see both at once.

Otherwise, it's a bit of a hassle to use.

Thanks for considering!

Hi, I have Windows 10 Pro OS.

I am an eHarmony subscriber, and the program Grammarly does not work, but it works when I use Google Chrome. Can you please help me?

Regards.

Today, 2026-10-24, it appears google is blocking me from using most tabs in Firefox. Versions are 115.18.0esr (64-bit) and 100.0b7 (64-bit). Worked fine yesterday. I have various Win 7 versions on my three machines. I've been getting warning messages from google for some time about stopping support for Firefox and I contacted them to get a date, but never received a reply. On one machine, when I start Firefox, it immediately dies. On the other two machines, it only lets some websites run, but not my personal gmail or my HSU student gmail. I was planning to install Win 11 on at least one machine, just have done so yet. I could try upgrading to 115.43.1esr. Yes. I am a bit of a Luddite; I started working in computers in 1977.

I have no issues on other sites, even sites with embedded video content.

YouTube, however, performs extremely poorly whenever it is the active tab. Page loading is extremely slow visually - the page itself appears to be loaded, but elements haven't appeared, and some elements that should disappear when video playback begins (the YouTube logo, or the play/pause icons) persist on top of the video. Buttons and icons on the page are extremely slow to respond, even scrolling is very slow, and sometimes even mouse movement is slow - clicks take anything up to 15 seconds to register, and it takes several seconds for hover highlighting to appear.

Video playback, when it starts, may not actually be shown - that is, the audio plays, but nothing happens on-screen. Pressing pause often takes several seconds.

And, closing and reloading the tab often takes far too long as well - as in, the time between when I actually click the reload or close, and Firefox actually responds.

Sometimes, I will get the warning banner that the site is slow, but not always. If the banner appears, as long as the video is already playing clicking 'Stop' on the banner seems to resolve the issues (but, I can't use functions like the comment box, 'like' button, search bar, etc). If I do this without the video playing, I can't start the video - the playback controls no longer work.

I am reluctant to turn off uBlockOrigin or Disconnect to use YouTube. I've tried disabling other extensions to see if it makes any difference, and I've also tried switching off hardware acceleration and using the recommended performance settings instead. I haven't found any way to force YouTube to only show videos at 720p at most, but I've tried switching videos to 720p (and where I can, away from 60FPS). It makes no difference.

Are there more fine-grained performance settings that I'm missing? Is there something obvious I'm missing? It seems that it's literally only YouTube that performs this badly, and only for about the last two weeks.
