Ever since Monday, August 21, my browser has been having many unexpected crashes. As these crashes have been happening, I have done some research and found out that the latest versions of the Firefox browser and Adobe Flash Player have been using up a lot of memory and CPU. For instance, a recently opened browser uses up over 100 MB of memory, and a single YouTube page will cause the Flash Player to take up about 50-60 MB of memory. Since then, I've been using various programs and add-ons, such as MemoryFox and Firemin, to reduce Firefox's memory usage to 6-7 MB. However, the Flash Player is still using large amounts of memory, and the browser will still crash under conditions that it would have handled properly 3 or 4 weeks ago. If you could provide any help on the matter, I would greatly appreciate it, since I need my laptop in good condition for college work. I apologize if this letter was too long, but I thank you for you time irregardless.

When I am on a shopping website and I try to add something to my wish list or bag I get the javascript:void(0); in the bottom left hand corner of the screen and nothing happens. It doesn't add it to my bag or list. I have tried many things to resolve this but nothing has worked and this only started happening within the last month.

Hi There,

As of today I seem to be having a strange issue with Firefox 31, I'm unsure as to when this problem began as I haven't developed on this project for around 2 weeks. I have a PHP Development server running on localhost port 8000 using the following command: "bin\php -S localhost:8000 -c php.ini" (without quotes)

Upon trying to connect to this server via Firefox I'm presented with "Firefox can't establish a connection to the server at 127.0.0.1:8000." the message adjusts to show "localhost:8000" when connecting via that method, I've tried running Firefox in Safe Mode, reinstalling Firefox and also changing the network settings to "No Proxy" from "Using system proxy settings".

I'm able to connect through Chrome, IE and also by running a cURL command.

I just installed FF 63 on a 64-bit Windows 7 machine, and I'm getting SEC_ERROR_UNKNOWN_ISSUER errors at many, but not all, websites. Reaching the same websites via the same URLs using Chrome works fine.

All discussions of this problem seem to lead to https://support.mozilla.org/en-US/kb/error-codes-secure-websites?redirectlocale=en-US&redirectslug=troubleshoot-SEC_ERROR_UNKNOWN_ISSUER, but it's not helpful. My antivirus is Bitdefender Free, which appears to have no option for disabling the interception of secure connections.

Running FF in safe mode behaves the same as in "normal" mode: I get SEC_ERROR_UNKNOWN_ISSUER errors at many (but not all) websites.

Help? As things stand now, FF is pretty close to useless for me.

My laptop’s keyboard is not working in Mozilla at all but works anywhere else. I am currently writing this in Word and cut and pasting it into the feedback box. I really need to fix this because it’s really making things difficult because I really don’t want to use another browser. I’ve already tried restarting with all my plugins disabled but that hasn’t helped and I have the newest version of Mozilla. I have not downloaded anything recently and have no idea why this started. The last thing I typed was into youtube which worked but as soon as I typed something else my keyboard wouldn’t work.

Please help!

The computer knows as much about this site as I do which is precisely nothing. I have tried removing and reloading Firefox but the same problem occurs again and again. It is almost enough to drive me to Windows . Please advise how I can get rid of this problem.

My firefox has been fine for years up until a couple of days ago..

Sometimes when typing into google the autocomplete changes what im typing and sends me to the wrong site.

Any site i visit randomly redirects to worldsocialsurvey.com, and then takes me to loads of shopping pages when i cancel it.

I have ran virus scans with, Trend,Malwarebytes, Superantispyware and used combofix yet all of these say i am clean and nothing is wrong.

I have looked in about:config, and looked for anything that may redirect me like Babylon has a habit of doing, but it all appears to be fine.

Any ideas?

I have the latest version of firefox

The message comes often some seconds after a new site or adress was opened but not everytime. In earlier versions it was quite rare but now it comes almost with every change. The solution I have found in the web

    1- In the Firefox Address Bar, type in "About:config"
   2 - Click on button to continue
   3 - In search bar, type in "Websocket"
   4 - Set network.websocket.enabled to false 

worked just for the first day. The parameter is still set to false, but it does not help any more. I have the german message but the problem seems to be general and was not solved up to now.

Apparently pushed the wrong "Download" button. Now instead of my homepage (which I have reset), when I open Firefox the "search.conduit.com" page opens. I used the "about:config" procedure several times but it didn't work. There is nothing listed on "add/remove" that is related. Also scanned with Ad-aware, Super AntiSpyware and Norton 360. How do I clean search.conduit out of my browser?

I think that I'm pretty much done with FireFox and this may be the last straw. When I try to open Firefox, I'm getting the error message "A copy of Firefox is already open. Only one copy of Firefox can be open at a time." I tried all of the things that I could find on the web. There's no process running, so can't kill it via "Force Quit". I tried deleting the .parentlock file, using terminal, which seemed to be an approach that others suggested, but there was no such file. So, I'm stuck. Before I just completely give up on FF and move to Chrome, does anybody have any other ideas that might work?

I've been experiencing this problem since Firefox 18 and now that I have Firefox 20, it's still happening. I've done all the recommended things on the forum and checked around the net for possible fixes, nothings worked.

I've done the create new profile, malware check, check add-on's for updates and updated them to the latest updates, enabled/disabled add-on's/themes, etc. Nothings worked. Is there anyone out there with a fix? Not the stuff I have already mentioned or other stuff that's on the forum or already asked questions, those don't work. If not, I guess it'll be time to switch to chrome or something, cause this is a pain and to be frank, it just isn't worth that stress. I've had Firefox since Firefox 1, it'll be a shame to have to switch, but if no one knows how to fix it, then I will.
