Last night my Firefox 94.0.2 was hacked. When running Firefox, it would lock up my desktop. It disabled Norton Security, it disable other installed security software, and it disabled Windows System Restore. The hacker put up a message claiming to be Microsoft Support, with a phone number to call for help. This was a scam. I ran Firefox refresh, and that removed the hacker's program from Firefox, but then I had to do a full repair of my Window's installation. To protect my system, and prevent this from happening again, I added "xpinstall.enabled = false" into about.config. Please let me know if this will prevent a web site from installing a dangerous hack into Firefox, or if there is something else that I need to do. I have used Firefox for years, and have never encountered this problem before. Firefox is my favorite browser, but I am now afraid to use it. Please advise me what to do. Thanks, Jim

Hello! Since a month I have a strange problem - Firefox wont connect to any Google service - REcaptcha, google-analytics. Any site that uses these services would not load, or loads and waits until connection expires. I tried refreshing Firefox, the uninstalling and re-installing - the problem remains. I do not use any proxy or firewall on my computer. Opera and other browsers do not have this problem. Please, advice.

Until recently, I resisted allowing updates for Firefox because of the announcements of changes to prevent access to some technical kinds of website which I use. These include the public websites of the Paris Observatory which include useul informational ftp pages with important text, data and software files.

  I did recently allow a Firefox update, and now I find that I am cut off from access to these ftp pages. 
  How can I re-enable access to ftp? If it can't be done in the new version of Firefox, how can I return to an older Firefox version that does allow such access?

I am a Firefox user for 5 years now and never had such bad experience before. Since 2022 February 8 my Firefox application keeps crashing all the time. The browser opens and I can open webpages as well, but shortly after opening the websites, most of the pages result in Firefoxing crashing. I have latest version of Firefox and I have checked in safe / troubleshooting mode as well, but it did not help, Firefox still crashes. I have submitted a lot of crash reports in the last two days, the latest one has this ID: bp-94f69edd-95cb-40e3-84de-33cb20220210.

Please let me know what to do, as currently I cannot use Firefox and without a fix I have change to another web browser. Please also note that the same webpages that crash under Firefox work without errors in other browsers.

Is there any way of making sure it works consistently? I need to right click then click "Open Link in New Tab" to have it work reliably. Maybe something in about:config? Using latest Win7 64 bit Firefox. I've noticed this for probably 2 years now at least. Not sure if it ever worked 100%.

Firefox Version 103.0.1 Private Browsing Mode ('Never Remember History' is set).

Issue Started: The morning (Pacific time) of June 26 (Before then, clicking 'Clear Data' reset the KB to 0 without having to close and reopen the browser first, without having to 'refresh' the page after clearing the cache, and without having to restart the computer

The browser webpage has been refreshed, the browser closed and reopened, and the computer restarted but the cache does not reset.

Made several posts about floating videos and never one answer over the course of two years that I can recall. One of the biggest user problems with FF and we get -- nothing. If the developers are incapable of solving this go ahead and tell us ! We can look for other browser options. I have researched everything to do with the matter and the topic just round and round and round in circles. Dozens claim to have the answer but they are all full of hooey. Simple question -- time to start looking for options other than FF ?

Fire Fox no longer appears on the menu bar. I have to go to programs and open it each time I want to use Fire Fox. It will appear on the menu bar as long as I have it open but leaves the bar if I close it.

My current Theme is Dark Fox. But, previously my backgrounds and menus were all white and easy to read. Now for some reason they're black and difficult for me to deal with.

How do I reset to white and sync them on all my devices?

hi =)

So what hapened?

Now there is a huge white bar up top with my open tabs.

I prefer it how it was in v88

How do I get it to look like it was before the update?

Thanks)

(it really is terrible now, and while i always promoted FF to whoever, I think this unwanted change makes me want to look elsewhere, sadly)

For weeks I have been trying to find a solution to getting "Error 15" on certain websites when using Firefox. Opera and Edge have no problems with those sites, only Firefox has problems. I have tried every "fix" that I can find on the Mozilla site and none of them work. Is there anything else I should try before I abandon Firefox? Could it be that Firefox is now unreliable under Win7 Pro 64-bit? If so I will have to abandon it because this computer cannot run Win10 or later.

On a website I regularly visit Firefox does not know what to do with an mp3 link and will not prompt for an action.

How can I add MP3 to application list?

Copy of application list attached.

The update Firefox 100.0.1 ( or 2 ) has a bug: Firefox doesn't "see" the Fritz!Powerline ( LAN over Powerline adaptors ) and thus I can't enter the Fritz!Box. Even typing the IP address of the Fritz!Box doesn't help, because there is "no connecting" beyond the PC. The hardware works, so I can send and receive emails, but I can't access the internet via the firfox browser. Stepping back to 99.0.1, I had to "create a new profile" and all my previous ( before the update to 100.0.1 ) settings were lost, all bookmarks vanished ... I am rather angry, you know? This mail I'm sending via my notebook, as I this connects via 100 Mbit Lan network from an other room and as I had to "register" just to be able to complain ...

Lately I've found on a number of occasions that I've pasted the URL of an image into the Firefox address bar, but instead of the image loading, it's somehow led to a page opening - even though the URL STILL shows that it's an image and not a page?

Here's an example: https://64.media.tumblr.com/tumblr_m0p5jy7Lhh1qzfdsjo9_250.gif If I paste this GIF URL into the address bar, it often loads a page which says "tumblr" in the corner. But sometimes it just loads the image!?

Any idea what's going on here?

Firefox 94.0.1 (64-bit) ~ Windows 7 ~ No anti-virus except Windows Defender ~ No new extensions installed that haven't already been operating for weeks or longer.

Suddenly, after doing NOTHING except restarting my computer, my 'minimize', 'maximize', 'restore' and 'close' buttons are missing.

Any 'solutions' I've looked up talk about "Tablet Mode" (which I highly doubt I'm in) or other nonsense, the options for which either didn't exist when I opened suggested menus, or were simply techno-jargon-gobbledy-gook.

I doubt it's anything to do with Windows, since 'Waterfox', 'Microsoft Edge', 'Chrome' and other browsers all have their buttons intact.

When I opened Firefox in 'troubleshoot mode' the buttons were back. But nobody in those unhelpful 'help articles' said what to do after opening in troubleshoot mode, so I closed it, opened Firefox the usual way again, and the buttons were still missing.

Some logical, properly explained help would be greatly appreciated.

I have three devices, a desk top, a laptop and an iPad. The desktop is running a very outdated version of Firefox which means it is not compatable just to update it. The forum tried to help me with this a while back, but it was deemed not to be possible, and the best way would have been to do a fresh new install, but there was noway to save log-ins/passwords bookmarks. My devices all have the Firefox sync and that is so far working well. My question is, if I dragged my PC's Firefox into the present by performing a fresh new install, would my synced items install ok....after invoking the Sync feature on the new install. Logic tells me this should be so, as it worked ok with the new iPad, but I know from experience that logic doesn't always come into play. (Windows7) Many thanks

Since its latest update, I think, not sure which one as it has so very many, all causing me problems; firefox now no longer takes me to my homepage even tho that is the one I have chosen in my ff settings. It is the page that came on everytime I go online or open another window. It is my main email account and I go on it for many reasons through out the day. But now instead of taking me to my homepage it puts up a stupid message telling me the page doesn't need authentication and could be a trick, do I still want to go on it. As I am always working and going on this page this has become a big time waster and aggravation. I have tried several things, can't fix it. How do I get rid of this stupid message. My homepage has been the same for years.
