Firefox reset done worse; is slow, it crashes, will not open web pages, what should I do?

I had Windows 8/1 on my desktop Dell XPS 8500 with 24 GB of memory; a fast machine. I have a strong internet connection through my phone company Qwest; still works perfectly. Firefox worked fine. Then, last week or so I downloaded the upgrade of Windows 10 and since then, I continue to have problems. Firefox has slowed to a crawl, when it works. It often breaks down, web pages, I'll often does not open.
I tried to re - set my modem; no improvement.
I "asked" Mozilla how to fix and the answer I got online didn't make any sense. My Firefox - which is the last - had none of the places the answer told me to go.
Line 4 icon does not open as the answer say in 'options '.
Obviously, I'm not an expert, but I'm not a fool. I can follow the signs except the indications that I received was irrelevant to everything I could find on my Firefox to my display screen.
When I re - configure Firefox I lost too much of what I had saved. I won't do that again.
Is there a problem with Windows 10 and Firefox? Like I said, on 8.1 everything was exceptional.
Is there a conflict with software I use?
Where should I look to find answers?
Also, I could NOT access the Firefox health report. Directions to find it, I received are not
correspond to anything on my Firefox or my Options page.
I don't know what to do. Please, I hope you can help me.

  • Links will not open Web pages in Firefox (they will be in other browsers).

    I have re downloaded Firefox and reinstalled. But in vain. Won't open links in web pages. Can do in Safari. Download Chrome. But if I can't solve this problem, I'll have to give up Firefox.

    You can try Mode without failure of Firefox to see if the problem goes away? You can restart Firefox Safe mode either by:

    • By clicking on the menu button

      click Help

      and selecting restart with disabled modules, or;

    • Now the button option key when starting Firefox.

    If the problem is not present in Mode without failure of Firefox your problem is probably caused by an extension, theme or hardware acceleration.

  • Firefox still crashing when I open Facebook page.

    Firefox still crashing when I open Facebook page and crash that appear just after the report is in Greek (?!) I have an English version of Firefox.

    Hey Pacovilla,.

    Do you by chance have the LastPass Manager as an add-on of Firefox?
    (You can click the icon settings at the top right and choose Add ons).

    If you do, try to disable it, or from Firefox with no Add-ons to see if it works.

    This add-on seems to cause problems with Facebook on Firefox.

  • Firefox does not. Have done all troubleshooting but still does not. It will not open again now. Help please.

    After all the troubleshooting suggestions and also uninstall and reinstall Firefox, it won't always work. First it fades and a "does not" review appeared on the letterhead, with the pointer regarding the timer but nothing did. He was recently working fine for ages and I have not added anything, or deleted, so does not understand why he should stop suddenly work.
    I followed all the troubleshooting tips and disabled the plug ins, also removed a lot of the add - ons, did not always work. Then I uninstalled and re-installed.
    Now, it will still not open. A window pops up saying: he's fallen down and giving me the opportunity to re - start or leave. If I click on start, it only re - start.
    I even started it in SafeMode but which will not open either, it opens for about a minute then just closes.
    Please help, I really want to use any other search engine.

  • I don't know what to do about Java - my Mac is horribly slow, and I was advised to remove Java. But now it will not open Photoshop without Java.

    I don't know what to do about Java - my Mac is horribly slow, and I was advised to remove Java, it installs adware. The more I studied, the more information, I've seen say that most of the Web sites and software do not use Java on Mac more. So I deleted everything related with Java. But now it will not open Photoshop without Java. It will be safe if I get it directly from the Oracle site?

    You can download the installer for OS X directly from Oracle. Be sure to uncheck everything installs 'optional' which can appear at the beginning (I think on Windows it wants to install McAfee trial or the toolbar Bing - not really malware, more as desired and useless crud-ware).  I have a course Java JRE install on my MacBook Pro retina like some internal tools we have developed to work are currently java and I use a tool of u. Toronto called CytoScape is Java.  Sites Web will use Java Script, a very different beast and does not require a full Java or JRE install.  But with Java/JRE installed, just be sure of the source of any software that you download and install that is java based (as you should with all the software that you put on your machine).

    In addition, for PhotoShop, it says that you need the legacy Java 6 for OS X?  If so, then don't waste your time on the current version, just install that release 6 legacy.

  • 30.0 Firefox is so slow since updated. IE & Chrome not having problems loading pages, showing the blank pages, need two or more tests to open Web pages.

    30.0 Firefox is so slow since updated. IE & Chrome not having problems loading pages, showing the blank pages, need two or more tests to open Web pages. It seems to have something to do with the Visual data on the pages. My MSN homepage gets old and dies every time I open the page after the re-opening and closing of firefox. It takes forever! What is a memory drain? Each open page in a new session of firefox suffer the same fate.

  • Why can I not change opening Web page when starting Firefox with my PC no - adm account.

    I created a non - adm account on my Dell PC and installed Mozilla Firefox with my Adm account. In my non - Adm account, I used the Options menu to set my default to open the Web page to a Web page, that I love. However, when I restart Firefox, it comes back to the original default Firefox opening Web page. I don't have this problem with my administrator account.

    You can check for problems with preferences.

    Delete a possible user.js file and files numbered prefs-# .js and rename (or delete) the file prefs.js to reset all default prefs.

  • Extremely slow to open Web pages.

    My PC Dell 2 years contains Microsoft Windows XP Home Service Pack 2, with a processor Intel Pentium 4 3 GHZ processor and 504 MB of RAM; and I installed Norton Internet Security 2010.
    In the months it has become increasingly slow to open web pages, and in particular one I opened after the connection. This page now takes about 2 minutes to open, and then another 30 seconds before the download links and I have my slider control.
    I delete my files and cookies every day and I clean the disk and defrag every week, but nothing I try will speed up performance.
    A couple of days, I ran 2 scans of Registry Cleaner programs, and both indicated that I had literally thousands of flaws, including registry entries. Residual unwanted files; Elements of privacy; Bad Active X; and not optimized Performance characteristics.
    I considered buying one of the registry cleaners, but did a little research and found that they could cause even more problems that I currently have.
    I am somewhat a novice in the computer game, and I hope a kind person might explain in layman's language what is wrong and how I could fix it (easily).
    A big thank you to you all.

    Hi Malkeleah:
    My deepest apologies for not responding to your more sooner - my wife and I went away for 10 days just after your reply and when we arrived home I found myself with a virus, but I don't think I caught the computer!
    Both myself and this machine of circuits, wires and chips (or other) are now back to normal, and as promised, I'll give you a walk through of what has past. (will probably not be in the right order, but you'll get the gist of it, I'm sure). Son of my co-worker was the computer expert who got everything running.
    Basically, what he was doing was: remove all unnecessary programs that were run in the background. uninstall Norton 2010 SS and replace it with McAfee Security Suite (linked to the BT Net Protect Plus); Remove my 504 MB of RAM and replace it with 1.24 GB of RAM; back up everything I had in my computer on a flash drive. delete a lot of unnecessary programs from Windows; close the whole 'thing'; and restart using the 2 CD from Dell. There are other things that I'm sure he did, but I just don't remember.
    Thus, in a Word, my friend, this little baby now works as a Cray computer (starting & closing and opening web pages, all now faster than a bullet speeding - well, to me anyway).
    Malkeleah, as I said, the sequence, I gave you is probably all out of sync, and I realize that you're not a fan of McAfee, but my young friend knew a lot more than me and Philadelphia lawyer I was talking, and everything that has happened wonderfully since its development.
    Thanks a lot for your help. My apologies again for not having affect earlier; and if I ever need your help once again, I know how to get in touch.
    Sláinte!
