I can open links to my local files in IE but I need to be able to do this in Firefox. All of the information I found online is not helping. Is there a way to do it through the Internet settings?

I am using Firefox 4 with Fedora 15. Attaching files in yahoo mail is not working. It did work with Firefox 3 and Fedora 14. I can attach files in gmail with Firefox 4 / F15 and I can attach files in yahoo mail with Google Chrome. It is just the combination Firefox 4 with yahoo mail that fails. Any suggestions what to look for to resolve the problem will be appreciated. I have also tried with all add-ons disabled and in safemode but this did not change anything.

I was using the Firefox 4 beta for a while, and Youtube had always worked. Then when the final RC came out (or one of the last betas, don't fully remember), I immediately installed it, yet Youtube gave me the message stated above when trying to play any video. I have even tried switching to the HTML5 trial to no avail. I have been having to downgrade to the latest 3.6 version to be able to view Youtube videos.

I have lots of bookmarks in hierarchical folders sometimes 3 deep. Only some of them, and the first level of folders, were imported. How do I get them all? Manually? [Pathetic groan]

I spent about 40 minutes reading up on bookmarks on the Help site. No luck. I tried importing them again and received some more, again with folders at one hierarchy. Some of the bookmarks are also in the wrong place.

Every time I open Firefox I get the following message. We noticed you may have signed in or signed out in another window. Click OK to reload your page. Is this normal?

I have just installed the new FF (which actally looks a lot like Explorere). I used to be able to type a word into the address bar eg: Facebook, and I would either be redirected immediately to Facebook otherwise FF would perform a google search. Has this feature been eliminated or is there a setting that can do this.

BTW, I do not like the new FF. The previous version was much more user friendly and visually pleasing.

For a while now, Firefox has been randomly signing me out of certain websites. The ones most commonly (or at least noticed) affected are Facebook, LinkedIn, and a site I visit called Two Peas in a Bucket. It happens on both my desktop and my laptop, so it doesn't appear to be just related to one machine. Sometimes it happens when I close FF, but just now, it happened after I closed just a tab. I've cleared my cache, deleted the cookies for those sites, but nothing seems to help. It's been going since before I upgraded to the latest version of FF as well, so I don't think it's just this version that's having a problem. I've tried searching for a solution online and here, but can't find anything. It's quite frustrating... Any ideas?

I am using FireFox 4.0.1 and I have Yahoo in my menu bar. I would like to remove it. I do not have Yahoo installed on my computer. Did Yahoo come automatically with version 4.0?

Hey Every time I try to run firefox, I click on the shortcut on my desktop, and it will not open. I tried going to the mozillafirefox/firefox.exe to run it but with no luck. I watched the processes tab in task manager while trying to run firefox. It loads up for a few seconds then instantly ends. It will only open when run as administrator. I am running on windows 7 64 bit with the latest version of firefox (tried unistall/reinstall newest version, no luck). Any help is appreciated! Thanks!

The last update for firefox warned me if I downloaded it my realplayer would not work. I do not want to download the firefox 6 update if I will have an issue with realplayer

I spent 90 minutes in live chat yesterday without a resolution or follow up.

Suddenly Firefox can not display video, animation, flash, etc. It replaces this with white space (no errors, no red X).

I have uninstalled Firefox and reinstalled with no success. I have re-downloaded flash 10.1 with no success. Content settings are set to load images automatically. Clearing cache/history does not help.

This issue happens ONLY in Firefox. Chrome, Opera etc perform as normal.

This is a Windows 7, 64-bit OS.

When using Firefox, it does not happen on Internet Explorer, certain words are treated as a link, double underlined in blue, and if you click on the underlined word, they link to a website that is advertising a product. I think this is an advertising ploy, and I don't know what is on my computer that is making these words in the text show up as a link.

I have repeatedly set several applications as "pin as app" tabs on Firefox because I use them frequently throughout the day. Yet, when I close a browsing session and open a new one later, all the app tabs are gone and I have to start from square one. Very frustrating!

I use Command+W to close windows. Unfortunately I often hit Command+Q by mistake, and quit Firefox when I don't want to. Back when Firefox used to ask if I wanted to save my tabs, that gave me the opportunity to cancel quitting. But now there is nothing to prevent the huge pain in the neck of having to restart Firefox and wait for a zillion tabs and pages to load.

Please put in a choice to be warned before quitting regardless.

I've had Firefox 4 since the release date, but today it's been acting up - it's not loading certain webpages properly, removing all the formatting and just putting all the text/links/etc in a list along the left hand side of the window. It's also not showing some pictures at all any more, although they're all hosted on Photobucket. This is literally ther first time there's been a problem with it since updating, and I've not changed any settings on it at all, so I have no clue why it's suddenly broken. Is anyone else getting this?

when the bookmark toolbar is selected, a space for it appears where it should be (above the tabs) but with nothing on it. When you deselect, the space disappears. The items on the bookmark toolbar are accessible via the bookmarks menu (bookmarks/bookmarks toolbar). Another thing is that "organize bookmarks" option is not listed on the menu under bookmarks. Everything else is working fine.

The new Yahoo Mail wont work properly on Firefox it says that my internet connection is to slow and yet it works perfectly on explorer. How can I revert to the old yahoo mail?

Since installing Incredimail I have had the My Start Toolbar in both IE8 & Firefox4, I removed it from IE using Add/Remove programmes but it has not gone from Firefox 4 Any idears,??

The extraordinarily severe Firefox 4.0.1 memory leak issue(s) (at least as seen under Windows, but also other OSs that are affected), urgently needs to be formally addressed by official or officially delegated Mozilla technical experts, and all effective solutions, work-arounds, or troubleshooting tips for this precise situation should be provided in a single, centralized location. This is necessary because, as of now, there are a very considerable number of different posts, alleged solutions, and other strange suggestions, many of which either contradict each other or are ineffective or entirely wrong-headed in the first place.

A staggering number of FF 4 users are reporting this often astonishingly severe memory leak problem, while others who might justly be described as Firefox 4 apologists (well-intentioned, I'm sure) either deny the problem exists or offers suggestions or strategies that are either: (1) beyond the technical ken of most users; (2) would require many weeks of painstaking trial and error (such as enabling only one add-on or extension at a time, which is far more complex than one might at first think because most add-ons have numerous options which could very well affect the outcomes depending on their settings and/or depending on which web sites the user browses to, and/or depend on subtle interactions with other add-ons such that the problem would not appear if they were disabled at the time, etc., etc., etc.). Considering all these complexities, expecting users to "heal themselves" is both absurd and arguably arrogant as well.

I will provide more information in the other fields of this form, but I wish first to identify the extreme nature of this memory leak issue, which began only after updating from the latest version of FF 3: When I launch FF 4 from a saved session with several tabs already opened, it consumes no more than around 200 MB or RAM. After it finishes loading, with NO user interaction whatsoever (I just let it sit there, untouched), I bring up a process monitor and watch as Firefox 4 (just the .exe, not the container process) acquires at least 12 additional megabytes and often around 50 additional megabytes PER SECOND!

Yes, 12-50 megabytes of additional memory PER SECOND!

And I'm not doing anything at all.

Within ten minutes -- even while doing nothing whatsoever with FF -- FF 4's RAM footprint reaches about 1.5 GB (of 2.3 GB available to XP out of 4 GB physical RAM), and after 20-30 minutes it consumes all available RAM and thus VM usage soars, resulting in a dramatic increase in disk I/O.

This is, shall we say, unacceptable. FF 3.6.x had no such issue at all, no matter how many tabs were open and with almost exactly the same add-ons installed.

I realize that Mozilla is primarily a volunteer project, and I tremendously respect and profoundly admire every last one of you folks. And Firefox IS, in my view, the finest web browser in existence. I absolutely do NOT denigrate or minimize the enormous efforts you all have undertaken or the value of your products! That I ask for still more effort and for consolidation of your findings suggests just how highly I value these efforts as well as the wonderful fruits of your products rather than the reverse!

Thank you all

Naturally I have pop-up blocker functional but there is a new and really, really annoying "coupon" pop-up that is always on Amazon but also on other sites. Close the coupon window and it pops up every time I navigate to look at any product. It really is bad and vexingly doesn't even offer anything that the Amazon template doesn't already offer ("free shipping" above a certain expenditure on some items etc.). It has a distinctive green border and appears on other sites as well. How did they get around your software? How can I make this stop?
