Every time I try to use my camera or microphone on some websites from on firefox it says can't detect camera or microphone? It doesn't show up with the 'allow this website to access your camera/ microphone' pop up it does with other websites. I went into permissions and manually changed it myself and it said it still couldn't detect the camera/ microphone

I have Norton 360. I just reinstalled a brother printer and now I get the "Your browser is being managed by your organization". While I sync with my laptop, as others have said, I'm not an organization. There is an Enterprise policy .

I can't store or edit any bookmarks. How do I correct this? I need answers in very simple terms as I am very much a layman with computers. Thank You!

hi, I love supporting this independent browser - I know its not perfect but it does a great job of doing most things well.

However, and there is a big but. I can be in the middle of an investigation that requires sharing data to a new tab - on opening the tab I'm blocked from going further as Firefox needs to do an update! This is really infuriating. No update can be SO urgent that you stop me using the browser. This is the Microsoft mentality, and its wrong. Can you please investigate NOT forcing users to update their browser during session.

I teach an online Adobe Illustrator Course. Students upload (.ai) Adobe Illustrator files. Not .svg or .pdf. But Firefox changes the (.ai) extension to (.pdf) upon downloading. This is HIGHLY irritating. Firefox, in prior versions, did not do this. In Firefox settings for Applications, there isn't a choice for .ai (Adobe Illustrator) files. I 'assume' that when AI (artificial intelligence) became available is when Firefox began automatically changing (.ai) files to (.pdf). PLEASE SOLVE this as I have to manually change the (.pdf) extension BACK to (.ai) HUNDREDS of times a day.

When backing up bookmarks to HTML - HTML Back-Up does not include the TOOLBAR Bookmarks. Please advise how to include the toolbar bookmarks in HTML format. Thank you.

This feature/option is not working. I close with multiple tabs open, and restart and only the generic search/home page is there. It is tedious to have to reopen if many tabs have been used.

Hi,

I just updated to the latest version of Mozilla FireFox and my bookmarks dissappeard.

All are gone, I wonder how I can get them back?

Many thanks,

My local network is 10.10.10.x and I can't log into my NAS, web server or another computer on the local network... Internet access is fine. Happens on Wi-Fi or Ethernet.

If I access the same web address using Safari or Chrome it works just fine and it used to work before the software update to the 147 build.

So what switch/setting got kicked over during the upgrade that I have to turn off?

These kind of issues really make me mad at the Firefox Dev team... and I'm a very long time user.

I have updated my firefox on W11 laptop to the latest version 147.0.3 (64-bit) but it cannot show any pictures from some, but not all, sites. Not from www.svt.se nor from www.yr.no But its ok from other sites, as www.tradera.com and www.kjell.com

It works fine using android firefox version 147.0.3

Any ideas, anyone?

I on MacOS and I'm facing this issue last half of the year. As usual mac book user, I have many WIP items on my laptop, so I don't reload my laptop every day, even months it can leave without reloading.

So, after a workday I just closing it and come back tomorrow. When I back to the work and want to open new tab: Jira, Gmail, LinkedIn any other tabs - FireFox just keeping in loading state. In comparison, the Google Chrome that opened as well all the time but with fewer tabs, open the same links in seconds.

I though the FireFox is not latest version, and updating or re-starting of it, sometimes helped me to fix the issue. But now it seems stopped work either.

So, after a 5 years on FireFox I'm seriously started about my migration back to Google Chrome. I'm not sure that you can help me in this forum, but at least I would like to hear you option. Maybe anyone else have seen such behavior also and FireFox could find the issue

After updating to Firefox 147.0.3 all of my browser history (along with open tabs at the time of updating) is lost. I just updated to Windows 11 workstations (plus a couple of older Windows 10 workstations) to the current (Feb 2026) updates too. However the history data was lost before the Windows updates. I noticed that with the previous update of Firefox that saved login information was also lost. Who is doing your program updates, a chimp?

In the past when an update was done the browser would open back up with all of the previous versions session tabs in tact. But not now.

I've lost several tabs of research that was being done. Based on what has been happening, I will HAVE to change to some other browser. This is a shame as I've been a loyal Firefox user since day one. Good bye Mozilla and Firefox.

Obwohl in den Einstellung automatische Wiederherstellung alter Tabs eingestellt war, wurde dies nicht durchgeführt. Da ich es zu spät gemerkt hatte, konnte ich nicht über die Chronik die alte Sitzung wiederherstellen. Was kann ich jetzt machen?

When I try to exit the fire fox browser I delete all cookies then select exit and close it out. However when start my computer the next time I get a message that fire fox is already running and if I hit the cancel button it freezes the screen and I have no options to move on. So how should you do a normal shutdown off the browser?

Whenever i go on my yahoo mail I get a security alert that says: we have prevented your access to cowhuntforenenst.com I have run my anti virus and malwarebites thinking it may be a virus but it didn't come up as one. And it's only happening on firefox not other browsers. Is there a way to fix this?

It seems that the bookmarks function and history files are possibly "in use by another app". I do not understand much of this. I think it happened after an update. I tried a restore point. I deleted the Icons file as it seemed that might be an issue and they would automatically update on restart. I called Dell support, they could not fix it, neither could my smart, younger friends. So after hours of frustration, I had to install chrome, which I hate. What I want is for someone to just fix it. Its 2:30am and I need to get some sleep, I will check this tomorrow afternoon and see if I can get anywhere. Good night all!

The last few days I am unable to load websites that I regularly use. I get a cannot find error message. I have no clue what is going on. I turned off the vpn but that had no effect. This is really hindering my getting things done. Anyone with insight? I cleared the cash and cookies and all that, rebooted the browser as well as the desktop. Thanks

Is there something changeable in Firefox that would allow things to display better? On Tue, Feb 3, 2026 at 11:27 AM Douglas Flegal <toemeister@hotmail.com> wrote:

Answer: Thanks for flagging this. We’re aware that some parts of the newsletter may not display correctly in Firefox, while they do load in other browsers. Unfortunately, this is a browser-specific issue and not something we’re able to control on our end.
