Firefox Support Forum

i think my mozilla had recently an update. now all my bookmarks from Years back all gone!!!! thanks!!!! i tried to restore it but it says: unable to.... NOW WHAT????

Just now, after a massive and catastrophic SUPER-MELTDOWN-crash that arbitrarily decided to absolutely murder my day, ALL my tabs and windows and ALL history of "Recently Closed" tabs and windows is gone!

THIS IS COMPLETELY UNACCEPTABLE!

What is the reason for the existence of a SYNC feature if it isn't to MAKE SURE that a record of open tabs and windows is SECURELY maintained no matter how many times the application crashes, so that AT ALL TIMES, this information is kept INTACT, regardless of the state of the end users device? That is BY FAR the most important part of the sync feature! Are you telling me that there is no backup process of that information?

This is the kind of thing I never expected from you guys at Mozilla. I've been using Firefox for MANY years because I trust what you do. Today that trust has been SEVERELY and BRUTALLY wounded, most likely beyond repair...

I need you to fix this...

I need you to recover that information for me and I need you to make sure that what just happened could never, ever happen again unless God himself caused every digital storage unit on earth to disintegrate.

Since the latest update of Firefox, I now notice that each time I download anything the downloads icon in the toolbar expands the download history and remains in front of the browsing window until I click out of it. This behavior is reminiscent of the Chrome browser opening a pop-up bar every time I download anything which had to be manually closed — a regular irritant. I can see where some may prefer to have the pop ups, but I don't appreciate it becoming the default. Is there any way to disable this behavior so that it downloads in the background as it used to?

I used a siteblocker and i tried blocking about:addons, wouldn't allow it so someone tell me how. im literally trying to prevent myself from removing extension i literally jumped from one browser to another just to make this shit possible please.

How do I create a TLS 1.0, 1.1 exception in Firefox 100.0+ for my legacy devices (NAS), that no longer get firmware updates from the manufacture, that are on my private network and thier configuration is done through a web browser?

 I have been using Firefox browser for a long time, since it was called Mozilla browser.  An answer such as "I'm out of luck." means I will have to look for a new browser.  I prefer not to do that.  I trust the Mozilla brand and like you products and recommend them to my friends and customers.

I am reinstalling Windows\Firefox, and would like to hide\remove Bookmarks Toolbar & Other Bookmarks, as shown on the images. The Delete Folder option is greyed out for both, and Other Bookmarks is empty.

Both were hidden\removed in my original installation, but I can't remember how I did that. I've seen posts mentioning e.g. browser.toolbars.bookmarks.2h2020 (it doesn't exist) in About:config, right-clicking on the Other Bookmarks and uncheck it (it doesn't exist).

I'm using Firefox 101.0.1 (64 bit).

In settings, Start-up, I have the box checked for: "open previous windows and tabs" but it doesn't work. In order to do my work I need the 23 tabs I currently have open to show up again after a reboot of the browser or computer. What gives? How long will it take to get this corrected? Please give me help. Thanks, Mark

I've tried everything and read all the instructions but none work.

The latest update for Wondows 10 prevents Firefox (and Edge) from loading. Everything works fine once I've uninstalled the latest update so the problem is clearly theirs. I can't be the only person experiencing this problem but contacting Microsoft is next to impossible. I wonder if you can: 1) alert them to this issue; and 2) pressure them to fix it as constantly uninstalling the updates is a pain!

Lately I refreshed Firefox so I can boost it's performance cause it was running just a little bit slower than usual. Since than YouTube does not remember my selected resolution. Every time I close the tab, in the new tab it will have a much worse resolution and I did not have a problem until now. I am a system administrator and I'm currently learning programming as well, so I tried a lot of things to try to overcome this problem. The only extensions I have is Bitwarden, uBlock Origin, Cookie AutoDelete. And yes, youtube.com and *.google.com IS added to cookie AutoDelete. But even without it it's not working.

I have provided the Troubleshooting Information from about:support: Click Here for Troubleshooting Info

I also know that there are extensions like YouTube HD or Enhancer for YouTube what would solve this problem, but I would like to keep my extensions as minimal as possible.

Thank you!

Hi there

I've had firefox for years and never had much issues. I've never had this issue before the most recent update where now youtube videos constantly stutter. It's just Firefox as other browsers work fine. I've updated my graphics card and did a little bit of research but none of the fixes quite did it for me. In the past couple days I've always had Firefox crash on me twice, which hasn't happened before either. So I'm not sure what's going on, but I'm prone to point fingers at an update. I don't install extensions or themes, so the only extension I have really is uBlock Origin but that's been there forever. I've restarted my computer as well. It is not my resources, they are more than fine my RAM and CPU and Graphics Card. Task manager shows nothing is even above 50% (CPU, GPU, Memory) when playing the video. I've also tried creating a new profile and opening up a new profile. Same issue.

Can anyone suggest any fixes or is this a firefox update bug?

EDIT: This appears to be for all videos I am playing on Firefox. It also does not matter if I set it to the lowest quality, even 144p, it will still stutter nonstop.

My bookmarks have been broken up in the categories for years... ie: Research, Health, Shop, Weather, News, YouTube, etc. Suddenly today the News tab is missing from the Toolbar??? I can't find it when I search in Manage Bookmarks. Where did it go and how can I get it back???? Help!!

For some whatever-reasons (TLDR; I need to see the whole domain (including subdomains) clearly, unlike the default of only highlighting the TLD&second-level domains[1]) I want to disable the color-distinction which highlights TLD and second level domains.[2] Is there config to do so? If not where should I propose one?

Thanks.

[1]: for example ko.wikipedia.org and en.wikipedia.org will have wikipedia.org highlighted, and that's what I can't accept because ko.wikipedia.org (Korean) and en.wikipedia.org (English) is completely different site. (Some might say you can distinguish by language, but there are some English sites which shares the same domain on wikimedia.org, so you get the point here.) [2]: From the screenshot you can see only `wikipedia.org` is highlighted. I want to make it highlight all of en.wikipedia.org. (If I need to highlight everything including the site path below the TLD, I can accept that.)

In the last few weeks Firefox will not open even when using admin rights. NOTE: I have followed all available posts including multiple uninstalls (complete), deleting Firefox folders, reinstalling, etc. There have been no major (or known) changes to my Windows 10 Pro system. I run Heimdal Thor and Kaspersky antivirus protection and there have been no conflicts running both at any time. I also use Acronis Protection (I know it may seem like overkill but it works). I have turned off each of the above and Firefox still does not open. Firefox runs with no problems on my personal and work laptops. I am CompTia A+ Certified so somewhat knowledgeable (a little knowledge is a dangerous thing!) and have run sfc /scannow with no issues noted. Plus, two Heimdal support reps have logged onto my system, attempted to find a solution, found no issues with my system (Omen 880 even though I don't game). My wife is a dedicated Firefox user and wants it back.

I'm not sure if this is the cause but a few days after windows update my firefox crashes. I restart it and only screen opens and doesn't respond. Deleted Firefox, did fresh install. Firefox starts again but as soon as I log in my account, crashes again. Delete firefox and again fresh install. I don't login, I save 3 bookmarks and it crashes again. Delete firefox again and fresh install. But now firefox starts in the background (seen in task manager) but does not open a window. Download latest installer and try to install but now install says, "something went wrong" during the download. (could be the enterprise network here) this I tried a few times but no success.

So I download Firefox 101.0.1 ISO and install. But again running in background and no window.
