Diễn đàn hỗ trợ Firefox

I downloaded a program and I made sure the check boxes asking to install addons were disabled. Next thing I know I had a snap do toolbar on my firefox home page. I went to control panel and uninstalled the toolbar. now when I try to use firefox i get the snap do search page come on.

I have tried this in IE8, Newest firefox, Chrome and all get the same issue. I have looked at so many articals and done all of the suggested things but still no luck. I am also getting this on my laptop as well. Others are not getting this issue. Any help appreciated. These are pictures I am trying to view. I know we used to be able to view them. the site is something I have to log into. www.hceusa.com is the site but I would not be able to provide any other info to log in.

Firefox will not open. I tried every single troubleshoot recommendation, and it still won't work. I thought it may be under the "corrupt profile data" troubleshoot article, but when I followed the recommendations to change to a new profile, the profile manager would not open or run on my computer--as if it never existed. I tried downloading a different browser, and as soon as I imported my firefox data, it started misbehaving in the exact same way.

This is getting extremely frustrating. Anybody know what to do?

this problem has been going on for about a week now. while surfing, a window pops up saying " type error:oE is null at random times, and it then causes the browser to crash.

My Firefox crashes when trying to open 75% of web pages. I get the windows standard "Firefox is not responding" window after it freezes while trying to load the page.

I have singled out the problem to be the Shockwave Flash (11.5.502.149) plugin as everything works correctly with this disabled.

I have tried updated flash, uninstalling and re-installing it and the same with FF but nothing seems to work so far.

I have tried nearly everything I have seen suggested so far, but nothing seems to work. Firefox started hanging and lagging randomly a few days ago. When scrolling, hovering over buttons, clicking and typing, there tends to be a half-second or 1 second delay. Youtube videos and other video websites are basically unwatchable because they lag so much.

So far I have tried:

- starting firefox in safemode - resetting firefox - using hardware accelleration and not using hardware acceleration to see if there was any changes. - disabling all plugins and extensions and disabling each one-by-one to see if any took up a lot of memory usage. (Firefox memory usage was sometimes over 400 Mb) - downloading a freeware program called "Firemin" which apparently stops memory leaks when used to launch firefox. (Memory usage went from 350-400 Mb to 4-8 Mb !) This helped slightly when watching youtube videos but not with any other hanging and lagging problems.

I'm currently using Firefox 22.0.

Please if you have any suggestions respond because I do not want to have to resort to using Chrome. I am too used to using firefox and don't want to lose my bookmarks.

I keep getting this popup when using Firefox: "WARNING! your flash player may be out of date." I can tell it's phishing and I've never had this problem before. How can I get this to stop when using Firefox? It doesn't happen with IE.

Hello, I have this problem were whenever I try to type in something into the search or addresys bars, nothing happens. It's like the enter key isn't working. There is not usual picture next to the search bar (the one that shows you what search engine you're using. If it's google it shows a "g" next to the bar). Instead there is just a picture of a blank page as a placeholder. When I try to go in and add a new search engine by managing the search engine list, there is no option to add a new search engine. I have already tried going into the firefox folder on my computer and deleted the formhistory.sqlite file that is the supposed problem. No avail. I have even gone so far to delete and reinstall firefox to my computer. Well, that didn't work either. So I waited until the next update to see if my problem would be fixed THEN. I am currently on firefox 19.0, which is, as of writing, the most current version. I have tried restarting firefox with all addons removed. And for good measure, I deleted anything that ended with ".sqlite" in my firefox folder. I have tried to get the the about:config menu but do not know how considering how my address bar refuses to search. The greatest thing is that my address bar can still remember all the sites I've typed into it before, but for some unknown reason, cannot take me to any of them! I really don't know what to do next. I can only suppose that I could try completely deleting everything firefox has stored on my computer, as I don't know if just uninstalling the program actually did that. Other then my search bar problem, firefox has been acting fairly normally besides a few minor hiccups here and there. I am trying to remember if I downloaded anything before my search bar problems started or not, but it is always a possibility. I did download the firefox beta for windows 8 metro mode but I can't remember if that was before or after firefox started acting up. It's possible considering that softonic thought they were being really nice by including fbdownloader for free with my firefox metro browser. I am now no longer using softonic ever again. But that's all the evidence I can think up right off the tip of my head. Sorry if this was kinda long, and if any of my description isn't clear or make sense please ask and I can try to verify. Also, if I haven't said this already, my search bar is only not working in firefox. Chrome, Internet Explorer, and Safari are all working fine. Just my luck, I guess. If anyone could help me out, I'd be much obliged. Not being able to use the address bar has been really inefficient. Thank you.

I updated Mozilla yesterday and as it happened, this new PDF viewer it magically came with doesn't cooperate with the sites I need to use for my workplace. I want the old way of viewing PDF's back, or just to be able to disable the built-in PDF viewer so that I can use the Adobe PDF viewer and see my files once again. I found a way to disable all PDF viewers, through about:config, but now I have to download the PDF's to my desktop to even view them and this doesn't exactly flow with my work. Please help!

I downloaded some program from cnet, which used to be a reputable source, but now seems to be riddled with malware. The item I downloaded was not what I thought it was and I promptly removed it from my computer. I also managed to remove snap.do toolbar from all my browsers and my computer with little effort. HOWEVER, I cannot seem to get rid of snap.do. It seems as though it has hijacked the startpage of all my browsers, IE, Chrome,Safari, and Firefox all show snap.do whenever I open them. Of course I can click past this and go to a different page with no trouble. I can reset the homepage in tools-internet options and every time I hit the little house button, I can go back to that homepage. BUT if I turn my browser OFF, when I turn it back on, snap.do is the homepage once more. I have run anti-malware from Kaspersky and Webroot, neither finding anything. I have reset Firefox. I have done a flushDNS through config. I have checked all the settings for the LAN, Internet protocol, and HOSTS folder. I have even reset the router to factory settings. I am at a complete loss. All I want is for my homepage to come up when I open my browser, any browser. Since Firefox is my preferred browser, I am asking you. Please help Running: Windows XP SP3 with latest available Firefox

I was having issues with Videos playing so figured I had to update my Flashplayer, but when I tried to update it kept failing to install and on the Control Panel for Windows XP I clicked on the Flashplayer Icon and went to the Advanced Tab and it states that there are no ActiveX Control installed but I know I have ActiveX version 10 installed due to some Games I have installed on the PC. So I was wondering how FireFox worked with or around the ActiveX Controls. This is for my piece of mind and future reference as I do all my own Tech Support for my PC and am self taught through trial and error about XP. Am running an Intel Celeron processor, 697MHz with XP Service Pack 3, FireFox 12.0, 192MB of SD RAM. Yeah it's old but it works for what I do. LOL Anyway any info on this would be appreciated.

Thanks in Advance Craig

I do not appreciate Babylon.com taking over my computer without my permission. Please help me delete Babylon.com

Whenever I watch anything requiring Adobe Flash (a YouTube vid, an anime episode on Crunchyroll, the latest episode of a show on RoosterTeeth's website, etc) on my Firefox (Version 22), it's horribly laggy and slow, with the picture AND sound lagging and 'skipping', and occasionally for YouTube the image will 'pixellate' and/or the sound quality will nosedive. According to the right-click option, my Firefox uses Flash 11.8. However, watching a vid on my Internet Explorer 7, which uses Flash 10.0, produces no such problems; the picture and sound are excellent. This problem has persisted ever since shortly after I first installed and began using Firefox earlier this year, when I (apparently mistakenly) accepted the offer to update my Firefox's Adobe Flash to Version 11 (it kept giving me "your Flash is outdated" messages that I had to click away to watch a vid, and that annoyed me so I wanted to make it stop).

This problem has been plaguing me for several months, and now that RoosterTeeth no longer supports IE7, I am unable to properly watch their new episodes. I have tried nearly everything - disabling Hardware Acceleration (with Firefox AND with Adobe Flash), having other tabs closed, several Flash updates as they become available since this problem's inception, upgrading my graphics driver, desperate prayer to God (and I'm a fairly secular man), EVERYTHING.

Could someone please tell me what is causing this months-running problem and how I could possibly hope to fix it?
