there is already another question with the same problem I am having, but to be able comment on it I needed to ask my own question to register. I am running windows 8. I was using firefox when the prompt came up "firefox needs to update... and will reopen in a few moments". Firefox never reopened Instead I received an error message "C:\Program Files (x86)\Mozilla Firefox class not registered". I have uninstalled, reinstalled, deleted C:\Program Files (x86)\Mozilla Firefox , reinstalled and still receive the same error message "C:\Program Files (x86)\Mozilla Firefox class not registered". When I reinstall firefox it never opens its always comes up with the error message. Any solutions?

Facebook crashes Firefox when typing a comment by making "@" suggestions.

This is the same problem as https://support.mozilla.org/en-US/questions/987650

What the moderator, cor-el, did not understand and the poster could not seem to explain is that it is not Firefox's autofill that is the cause of the problem. So, clearing the forms history will not fix this issue.

It is Firefox's reaction to Facebook's attempt to present a dropdown list of friend and page suggestions for addition to your comment the same way it would if you typed "@" first. FB's attempt to make things simpler for it's users by doing this without the "@" symbol seems to be causing a conflict in Firefox that totally freezes the browser. "Mozilla Firefox (Not responding)" is displayed and no amount of waiting changes things. No option for a crash report or anything but to close it.

It happens randomly when typing in a comment or status, usually after 2 or 3 letters into a word that matches the first 2 or 3 letters of someone in your friends list or liked/followed pages/groups or even other commentators. Unfortunately, for me, that means even typing "the" can cause this issue. As far as I can tell, there is no way to turn this off in FB's settings.

I understand that this is caused by Facebooks implementation of the feature, but it is my hope that someone at Mozilla can offer a fix or patch for this since it's unclear how many FF users are affected and it may take some time before FB addresses the issue.

Please help. I would really prefer to not have to type my comments in Notepad before pasting them on FB.

Thanks.

With all due respect, Problem: YouTube videos not streaming on Firefox. Error Message displayed:- "an error occurred, please try again later".

Specifications: Mozilla Firefox Version 31 beta 7. Windows 8 64 bit.

Procedures I've followed to resolve problem: 1)Started Firefox in safe mode. 2)Reset Firefox. 3)Uninstalled Firefox using "YOUR UNINSTALLER". 4)After uninstalling Deleted folder: C:\Users\admin\AppData\Roaming\Mozilla 5)Re-installed Firefox. 6)Uninstalled Google Chrome. 7)Updated Adobe Flash Player. 8)Updated Shock wave Player. 9)Deleted and Re-installed Adobe Flash Player and Shock wave Player.

NO RESULT FORM ABOVE PROCEDURES

Failure attempts: 1)Tried to delete/remove Addons, But unfortunately there is no option for removing or deleting Addons. and that is annoying!

As diagnosed by myself: The problem might be because of some Addons but I am unable to delete any addon.(Not Sure) YouTube is streaming videos in Google Chrome and IE.

Need Some Expert Advise. Thanks in advance, Warm Regards.

Hello, after update to Firefox 26.0 (CS version, but as I checked, e.g. SK or LV versions does that too, I did not try EN version), my pages (written in PHP, running on Apache) after sending form with method POST starts to ignore header content-type charset=utf8 and broke the encoding by reset to win1250. In older versions of Firefox and other browsers, no such problem appear. I did some search in older messages, but without result. Could you please suggest some solution? Thank you, Lida Chroma

I cannot sync my firefox after a format of my HDD. I am synced on my android phone, but cannot get a reset password for my account. I cannot get to my addons nor bookmarks. Reset does not work, new account on my email doesnt do either. "Attempt limit exceeded." is all I get from firefox. I am one step from getting rid of it after many, many years of our relationship. I pitty that firefox is getting slower and slower, I get more and more problems, and still hang on to it. Today I couldt find any useful help. Its quite disturbing. Maybe it has come to "Attempt limit exceeded."?

Please help.

I am unable to re install Firefox on my Windows 8 PC. Since yesterday trying to launch Firefox causes my PC to crash and then as it shuts down I am advised to search online for bad_spool_header info

After I did (both Chrome and Explorer work) I found a" search by conduit" add on which I was able to uninstall and completely (?) clean out from my system I also ran several malware tests and cleaned out my registry keys. The computer works fine only issue is with Firefox. Since Firefox immediately launches after install and this causes PC to crash I am stuck in an endless loop and cannot even go into safe mode for Firefox, attempting to do that to stop the launch caused not only a crash but a weird vibrating noise from PC.

Please note I use Win 8 as old style Win programs from regular desktop/start menu, not via app/charms interface (in case you are sending me instructions). Hope you can help me get my Firefox back!

Every time I go to Yahoo.com and try to sign into my mail accounts, I get the Recaptcha. It may ask me to click on all cars in the pictures. When I do that I notice the "Continue" button is superimposed on the pictures of the cars and then when I try to click on the "Continue" button, I get a circle with a diagonal slash mark through it. Yahoo won't help me with this until I pay money. This problem started when their pay for phone tech program started. Please help!

For a new search I open up a new tab and start typing in the Awesome Bar. Then, before I hit ENTER, I Alt+Tab to a different program in Windows and Alt+Tab back to FF with the INTENT of typing/pasting the rest of my search query, only to find out that what I had typed initially has been replaced with the new tab's URL (homepage). This does not happen when I set the new tabs to be FF's default or I use a tab that is NOT new (no problem when The problem does not occur when I navigate to my homepage from an old tab and try to search.

It's quite common for me to Alt+Tab away from FF in the middle of typing my search query so that I can type in particular phrases precisely (e.g. an error message).

Here are some workarounds that are problematic, please do not suggest them:

1. Do not set new tab to display homepage / do not have a homepage / set new tabs to be FF default then press Alt+Home to view homepage.

2. Use search bar (Ctrl+K) instead of awesome bar. Can't use shortcuts for different search engines in search bar, also doesn't give suggestions.

3. Start the query with what's on the other window; type or paste in this information first.

This problem did not exist for earlier versions of FF. It started a few versions ago.

...it opens .html files when it's not running.

1. .html files are set to default to be opened by Firefox. 2. Click on any .html file (or a link in Thunderbird or any other program) and nothing happens. 3. Nothing happens if Firefox is running for first time since computer was started and user logged in. 4. If you close Firefox or restart it via console, then it all starts working and opens .html with no problem. 5. What is this magic and why do I need to keep restarting Firefox each time to fix this? 6. Firefox is clean installed. I did try safe boot with no addons.

colors are always basic and no css buttons are displayed. most sites are unusable. google main page text box is lagging. windows 8.1. i'm not exactly layman and have reinstalled FF 2 times, including deletion of all data folders and registry entries, before i realized the problem is deeper (that IE11 doesn't work neither - note that chrome uses a different engine or setting and works just fine). Either some windows component is bugged, or some setting has been accidentally changed, and i can't find it. Been checking accessibility options (nothing checked), page style (basic), scanning for viruses, doing stupid things advised around the web to no avail. i guess either my FF/IE think i'm on some primitive device (whereas i'm on a desktop pc), or they neglect CSS for some reason.

i had problems posting this question from FF so i'm posting it from chrome - i guess it's useless to try the troubleshooting information button. there is no dependence on FF version. i can try posting again if this info is critical.

Greetings, I have been having the with Adobe Flash crashing. I also get many Tab Crashes. Sites that use Adobe Flash don't work. Tried everything. Here are my 5 latest Crash IDs and maybe this might help figure out the problem. Windows10; Adobe Flash 23; FF 50.0.2. Using FF SafeMode does not solve problem. Uninstalled/reinstalled FF and Adobe Flash does not help.

When I click on an area in a site that requires Adobe Flash, the FF menu item begin to pulsate, making it difficult to select a menu item and eventually can cause a Tab Crash in FF. Two such sites are: https://www.speakeasy.net/speedtest/ and http://www.speedtest.net/

Crash ID: bp-25fc8276-04d0-4a9c-8658-ac51d2161106 Crash ID: bp-ac42088f-05a7-4e90-9baa-155222161106 Crash ID: bp-09c61a5e-5d96-4be3-8b37-872eb2161106 Crash ID: bp-6fbcfc92-fe94-4194-9c72-e27752161106 Crash ID: bp-ed581173-4604-476d-ba2e-4aa2c2161106
