I attempted to install Firefox by clicking on the download button then clicking "run" on the pop-up for Firefox Installer in Internet Explorer. Then I click "run" again on the Open File Security Warning pop-up. The hourglass pops up for a few seconds and then disappears. I've also saved it to my desktop and tried to open from there. In that instance it says it is extracting, then an hourglass, then nothing. I've also tried "save and run" as well. I have all the system requirements. Thanks for your help!

If Firefox is open, system hangs, runs slowly, loses mouse functionality, and automatically toggles between open programs. Started after an update several months ago. The next update fixed issues, but the following update brought them back. After an update this morning, everything got worse, so I uninstalled Firefox, and everything improved. But I need it back - I use the internet for a bunch of stuff.

Am operating on Windows 7 Professional.

i'm running win10 and ff 44 x64.

Thanks, David.

So Firefox decided to quietly update from 32bit to 64bit, and it will not start after that (i.e. It just crashes). No Crash Reporter popping up from the crash.

Clean installed, removed every mozilla firefox folder from users, and it still doesnt work. I had to move back to the 32bit version

The instructions for adding folders to bookmarks is not correct. I can't find the "Show all Bookmarks" at the bottom of the list. Where is that item?

In the old Outlook Express, I could set up folders to sort bookmarks. The instructions in support do not appear to be correct. How do I add folders to the Bookmarks and then move bookmarks into the folders so that I can more easily find the one I am looking for? The bookmarks are not even sorted alphabetically, which would be helpful if folders cannot be set up. Again, in the old Outlook Express, I could move bookmarks in the list so that I could alphabetize them, even within folders. Can someone please let me know how to do this in Thunderbird?

I`m using an older version of Firefox because when I update to a newer version I don`t like the changes. Since getting a message the other day that Firefox had crashed, my bookmarks are all out of order and I can`t change the order by clicking and dragging. How can I put my bookmarks back in the order I would like?

Firefox keeps blocking all sites

Hi, For as long as I remember, i preferred using Firefox as my standard browser, heck I always had only one browser, Firefox. But not until recently I've encountered a serious problem with Firefox that actually made me uninstall it and use Chrome! o.O

I had to reinstall my entire system, which went quite well until I downloaded and installed Firefox and used it for a couple of minutes. At first everything was fine, Firefox took me everywhere as I was used to. But when I customized Firefox to my own preferences, added the new-tab-override extension and changed the home page address Firefox all of a sudden started blocking access to all websites. I am permanently getting the following warning: "Your connection is not secure" with the error code: "Error code: SEC_ERROR_UNKNOWN_ISSUER". Even to go on this site I was forced to use a different browser. :(

I am quite a computer veteran (or I at least think I am) but I tried and tried and tried to solve the issue but I had no success. I looked up people who were experiencing similar problems but I couldn't find a working solution. I tried reinstalling Firefox, which at first seemed to work again, but after a couple of minutes and some adjustments to my aforementioned preferences, it blocked all access again and made me quite frustrated that this can happen just like that. At least I would have hoped that Firefox would ask me if it should block sites in this manner, but I cant fix it at all. I'm now using Chrome, which I detest. I want my old Firefox back! Good ol' Firefox that doesn't scr€w me over when I install it, change the homepage and change the new-tab... Hope you can help me out here, or I'll be stuck with Chrome for the rest of my computing life... x(

Q: How do I fix this "Error code: SEC_ERROR_UNKNOWN_ISSUER" from occurring?

[Problem after passing to Firefox 64 bits - now I've the 55.0.3 version. Bug already there after fix procedure of firefox and without plugins] When I want to save a file (=when I click on "browse" button), the dialog box of Windows appears and freezes (and Firefox crashes without specific error message). I'm under Windows 7, I've got comodo but nothing about Windows or firefox is blocked]. There is one week, this bug appears after some usings/download [I need to do the fix procedure when the bug appears]. now it's directly during the first one. It's very embarassing. I've got Chrome for waiting ... but I don't want to use Chrome ;-) help !!!!

[for example, I can't use the button "Browse an image" in this Web page, else Firefox crashes]

I was having Firefox (slow) performance issues and decided to re-install. After re-installation, firefox would not start (could see the process firing but closing immeadiatey, the app didnt even open). Upon advice received here (, installed an earlier version (54) of firefox which started. Then I did all the updates to recent versions and it kept working. Only then I realized I had just installed the 32-bit version. As I try to use the same procedure to install the 64-bit version, I am back to the same problem (firefox not starting). Now I found that I can get firefox to start by renaming the firefox.exe to something else (e.g. firefox1.exe). It does start but it seems the intial performance problems persist. Additionally, it keeps asking me if I want to make Firefox my default browser. I keep answering yes to no effect as every time I start firefox it asks me the same thing. If I try to make Firefox my default browser through windows settings (or control panel) firefox is not listed by windows as an installed application. In short, I cannot get the 64-bit installation being recognized by windows (windows 10 home) and without renaming the exe file. In addition It seems to perform poorly.

I have also checked for malware, nothing detected.
