My desktop is running Windows 8, which recently crashed. Since then, every time I start up, Firefox 17.1 (which is in the startuo folder) does not load, but brings up an error window saying (Couldn't load XPCOM). Dismissing the window then allows me to start Firefox myself. I have uninstalled Firefox (but not the personal stuff), downloaded a new copy of Firefox 17.1 and re-installed.... same thing happens.

Just to clarify ..... this only happens once, following the initial boot up of the desktop. I dismiss the error window and all is well after that.

Any bright ideas please?

What is XPCOM referring to? A missing dll file? can I find this file elsewhere and move it to the correct location?

Many regards.

Morning. Two days ago I reinstalled FF on on clean install of W7. After installing every (software, ext., personas, etc) when I start FF, the "add tab" is sometimes on the far right (which does not bother me), but when I clik on the plus sign, the new tab opens to "Delta Search".

Other times I start FF, and the plus sign is right nest to the tab. And when I click on that Google opens, as it should.

Right now, I'm writing/sending this in Safe Mode. All my software that I have installed, is the same software I have on my XP machine (minus a few things that would not work/or needed anymore).

Any thoughts?

(sorry for long link) i have tried disabling some of my add-ons to no avail. i have scanned my computer with Avast! and malware bytes. i haven't been on any dodgy sites when it happens. i have just realised, but i think it might be every time i click a link, a new page with an ad will open. it only happens on any link once.

any ideas?

Hi, after updating to Java 7 update 10 Java stopped working. Plug in checker indicates Java Deployment Toolkit 7.0.100.18 is installed correctly, but Java test page says plugin needed and Java Runtime Environment 1.7 u10 is available. Install fails. Uninstalled Java and tried manual install (including as administrator) but no resolution. All old Java versions have been uninstalled. Thank you for your time.

Is there a way to disable the HSTS ( HTTP Strict Transport Security ) list built into Firefox or to allow exceptions?

HSTS is problematic in that it incorrectly assumes that all users trust the default list of CAs and makes the adding of exceptions impossible even by advanced users.

For example, torproject.org is inaccessible on Firefox unless I am willing to trust DigiCert to never sign a fake certificate either by negligence or by court order of any country in witch they operate, thereby making every https: site ( not just torproject.org ) vulnerable to a MITM attack.

A user disabling CAs in the browser is not unreasonable given the ever growing list of CAs built into Firefox ( each one a potential point of failure ), the number of CAs that have been recently compromised and the very low standards required to obtain a certificate.

While I understand the desire to protect the average user who doesn't understand how certificates work and will click past warnings without reading them, this protection should not come at the expense of more security conscious users.

I would recommend an about:config setting that would allow the creation of exceptions by users who explicitly choose to do so.

So far the only kludge I have been able to come up with is to modify c:\program files\mozilla firefox\xul.dll with a hex editor and replace the sites on the list ( this is far from an ideal solution ).

Hi, My Firefox plug-in check is telling me that there is an update for Java, but when I visit the link it's still taking me to the old update (the Java 7 update 9). Also, according to the Java test page, Java 7u9 is still showing that it's the latest...it says I have the recommended version.

Is there an newer update somewhere?

Thanks.

Ever since Firefox updated to 17.0.1, the flash and silverlight plugins just disappeared. I tried to clean installing the flash player, it did not work. I tried clean installing an earlier version of flash player, that did not work either. The plugin manager is less than useless as it says the plugin has been successfully installed yet I cannot use Netflix nor any flash video. I did all of the above once again with all plugins and addons disabled, and still nothing happened.


This is getting really frustrating and I am in fact contemplating moving to chrome after the string of crappy, forced updates mozilla has shoved down my throat... PLEASE HELP!

I updated my wife's WinXP laptop to Firefox 24 last night and as soon as she tried to run RuneScape (runescape.com) the above message appeared in a window. (I can't remember the exact wording.) On one hand it appears to be telling her to activate something. On the other hand it seems to say don't activate it. How should she or I respond to this message?

As of late, my Firefox browser has been freezing my entire computer. It keeps saying that it is "not responding", my mouse turns into that blue circular loading screen, I can't exit anything, I can't even open task manager, I have to take the battery out just for my computer to turn off.

I scanned everything with Norton; didn't detect anything. I even did the Norton Power Eraser, still nothing. I set Firefox to run the program as an administrator and I thought it was fixed but it wasn't.

I even update my plug-ins and for some reason, your website keeps telling me I need to update the same ones, so I can't even rely on that.

I noticed that it does happen when I'm on a Youtube page. Like when I've paused a video.

It opens fast, it browses fast, it goes to certain websites fast. It's this annoyance that has really bothered me and has considered me switching to Google Chrome.

If you don't want me to, then tell me how to fix this issue.

we have firefox esr version which we use in kiosk mode. we want to disable navigation bar but should be able to open multiple tabs and access them.

Now problem is : once i enable tabs and navbar is hidden. then we are not able to access next/previous tabs. key shortcut (Ctrl+tab or Ctrl+shift+tab) doesn't work. so we can not see another tab.

once i show navbar/tabs then address bar/search bar is also visible which we don't want.

Our requirement is to see multiple tabs with no address/search bar. Please provide help on how we can go to solve this.

Thanks

About 4 days ago, Adobe Flash Player updated to 11.5 and started crashing multiple times a day. So when Firefox updated to 17 today, I immediately uninstalled Firefox and reinstalled the new versions in hope that the problems would be fixed. When that wasn't the case, I followed all the steps for Flash 11.3 and nothing has worked. This is only happening in Firefox. Flash works fine in Google Chrome and in Internet Explorer. My school's primary requirement is that I use Firefox with Flash to do my schoolwork. This is an issue if I have to restart Firefox multiple times during my session. 25% of all Flash crashes also crash Firefox. I need help soon.

I am running the latest version of Firefox (17.0.1)

I have a number of add-ons all of which are disabled and which I would like to remove. Unfortunately there is no remove button.

I have read the FAQs and community help which tells me that if there is no remove button then the add-ons are there through being added globally by other software. However on of the add-ons that I want to remove is Google Toolbar for Firefox - how could that have been added by another application?

Any suggestions gratefull received.
