I keep getting a screen popping up that says "Urgent Firefox Update". My protection software is blocking it, saying it's a Trojan. When I go to Mozilla, it says my Firefox is up to date. Is there an Urget Update or not?

We used to be able to toggle the navigation bar on and off with Ctrl-L. New, "improved" versions made it difficult so a plug-in was created to "hide" the navigation bar but it didn't work consistently and newer versions of FF disabled it. I am holding off updating until this problem get fixed

Couldn't open original download ("Blocked Publisher" notification). This morning, I received a second notification from a different URL. Smells like a malware scam to me.

Firefox 47.0 on Windows 7, HP, 64bit.

Margins in the Page Setup... dialog box were in inches. A couple of updates ago they changed to mm. In about:config I've reset to default values all printer settings related to paper size and margins with no luck.

Is this a permanent change to Firefox or is there a way to reset to inches?

seems the reading of lengths of mp3 files is wrong in the newest public version of firefox, please refer to the screen shots.. firefox, edge, chrome.. site: www.djjaybird.com every browser has a small difference, firefox is completely fubar.. the image uploader is not working on this page; please see: www.djjaybird.com/chrome.png www.djjaybird.com/edge.png www.djjaybird.com/firefox.png

I had selected "Don't open tabs until selected" but all of a sudden they are all opening on startup. The "Don't open tabs until selected" option is not there anymore when I go to Options. What can I do? This is urgent because I have multiple tabs open and they're all going strong at the same time and some of them are YouTube videos!

I was removing VideoConvert by myway and then found I'd lost Most Visited facility tab, so I was following a Support advice to go to browser.places.smartBookmarksVersion;7 - double click amend value to 0 - and etc. I tried this several times and some how I managed to convert the 'Type' to String instead of integer.... so I then tried to alter it back to 'integer - unsuccessfully, so now find I cannot change it back.

And I still do not have the Most Visited facility.

What should I do?

Hello, Version 47.0 of Firefox has just been installed on my PC and I find that it is impossible to change the magification on the screen. It seems to be permanently set on 100% and neither the minus or plus buttons do anything.

I am unable to sign in. My password reset doesn't work 1: Click on "My password isn't working" 2: Enter email address. 3: Receive confirmation. 4: Enter new password. 5: Enter username and new password. 6: Receive the message "Please enter a correct username and password. Note that both fields are case-sensitive."

I have entered both my username and my email address. I have entered as many passwords as I can remember using in my lifetime. Nothing seems to work.

I have just created a new username with a new email address and it seems to work. Past experience has shown that once I leave this session I will never, ever, be able to logon again. So, this is my only attempt to ask a question. My next attempt will fail because I can't logon.

My inability to logon is long standing, going back for a couple of years or so. There is no way that I know of to ask a question unless I am logged on, and there is no way to logon. Catch-22.

Since I am unable to logon I don't believe that there is any way that I can verify any answer directly, and I can't respond to give any more needed information. I am stuck.

I recently bought a new computer with windows 10 and ever since, the left and right arrows are missing on the yahoo news scroll bar. So I can only read the first 5 stories and not 80 (as shown in the picture) . I checked the chrome and microsoft edge browsers but the arrows are missing there as well. Any help would be greatly appreciated.

Ever since the MAFF extension was introduced, I've downloaded literally hundreds of web pages archived in that format (I fell in love with it because the format used up so much less space than the mht format). Only problem is, I cannot open them in Windows 7 because it will not let me add Firefox to the list of available programs even after I browse to the firefox.exe after right-clicking the file and selecting "Open With" in the context menu. Is there a reg fix for this?

P.S.: I'm planning to install the Extended Support Release version of Firefox which should give me another six months of support for this extension while I come up with an alternative for archiving web pages. But for now, I desperately need to open these files because prior to switching to the Windows 7 machine I'd downloaded a boatload of maff archived pages containing instructions and tutorials I needed to ease my transition to Win 7.

Thanks,

I want to be able to open a new tab in an existing window from the command line on Mac OS X. The help indicates that I should be able to do this by running:

/Applications/Firefox.app/Contents/MacOS/firefox-bin --new-tab <url>

but this attempts to open a second copy of the browser, which results in the error:

"A copy of Firefox is already open. Only one copy of Firefox can be open at a time."

Is there a way round this?

Clicking the above link in FF47 has normally displayed until not long ago a list of my e-mail clients present on my Win 10 Pro 64-bit PC. In the list, Thunderbird (my default) was highlighted. After confirming it, Thunderbird (v. 42.2) was launched with the intended URL (of the given Web page) in the e-mail body. This was what I wanted. Several days ago, the e-mail link stopped working and it does not do anything any longer although it behaves (in the toolbar) as "live" (not "dead") icon. I am an advanced user but cannot find out or figure out what has happened and how to restore its previous normal functionality. Let me add that I have quite a number of add-ons in FF, some of which I have added recently (they are all related to security). Please, advise what should be done to solve my problem. Thank you for your attention.

I received notice from Firefox about its latest update. After completing the update (47.0), the cache will not clear to '0' as it has done for years. I went to about:cache and saw a 'cache2' that will not clear 62kb. I know this is not much, but I do not like the fact that it will no longer completely zero. Then I noticed a folder called 'doomed'.

Can cache2 be disabled? Is there someway to completely clear cache2? Is 'doomed' malware?

Upgraded to 47 (had difficulty where normally I don't). Slowed down so slow so I ran Ccleaner (which normally dumps 400 to 500mbs maybe). Now it dumps up to 1500 mbs and I watch it scroll through Internet Explorer - seems like all temp files go through IE as well as Firefox. I tried turning IE off - did not help so I turned it back on. I just increased my internet provider speed from 7 to 12mgs (now with WiFi). On my network I only have my desktop and my one older Kindle. I have watchnet and only see those two items on my network. This is terrible and I have to keep running CCleaner to even use my email. How disappointing. Please, I would appreciate help - how can I roll back to version 46? Thanks so much.

I have tried this a few times and still goes back to old way - only homepage opens, and new tab shows tiles, I click show blank page and next time goes back to tiles. Thanks

I have two PCs. One if them has updated to version 48 yestarday. The other one will not update. When I go to the 'about firefox" page it checks and says my firefox is up to date with 47.0.1.

I can provide console logs and all that are up to date. But I don't understand most of what the logs say or what they are supposed to display. Any help is appreciated.

I'll link to the console logs here:

I'll use this link for all of the files anyone needs (logs, pictures, etc.)

My router is a Netgear WNR2000v5 with the latest firmware update.
